For those who know me well, know that I’ve been in the automotive racing industry for 12 years and I mainly now deal with data acquisition and track support. One of my specialties is the installation of data logging equipment - mainly MoTec and other systems to cars, bikes, boats, planes and other interesting platforms - even trains.

So I've decided to set upon my own bike to do some more research with proper data logging on bikes and not taping your iPhone to your tank. Since there are a lot of different brands at different prices, I've decided to go with a unit we sell that is affordable - let's face it, how many of you could afford a MoTec Dash with logging and GPS, that unit installed would set you back approx $ 10,000.

The unit I will be using is the Race Technology DL1 GPS logger. It is a small unit that basically measures raw data as voltage, freq and GPS with additional rpm, speed and serial inputs. So those of you with a genuine OBDII diagnostics system on your bike can log with a simple Can loom connected.



These units retail for $ 1395 inc and have genuine 20Hz GPS, 8 AV inputs, 4 Speed, 2 RPM (1 x high and 1 x low) and a bit more. They can be combined with their Dash 2 and also the new Video 4 system which I will talk about later when I install it. Also sorry for the pictures. I used my phone camera, as I forgot to bring my camera from home.

Here are some more technical details and pictures.
Race Technology DL1 Logger

I have quickly made up a data loom consisting of a few AV inputs and RPM. I have allowed for speed as well, but will be using the GPS speed for now.



I’m installing this into my 2008 Yamaha R6 which has a small amount of room under the pillion seat to mount the main unit. It has to be close to level with the bike at ride height (Inc rider) to get the Long G trace accurate. Since Lateral G is not used this doesn't matter - but have squared the unit up for that as well. As you can see below I have made a simple bent bracket to level the unit in the rear tray. My power and data loom then goes forward to the under seat section.




Under the seat is the Denso 32Bit ECU and Battery, Inc a few relays. Here I will tap into the sensors I require for now and Ignition power.


First the Ignition feed - this needs to be a good feed that isn't disturbed by engine kill or starting voltage noise. So I've decided to go for the ignition feed that runs the starter solenoid. This is feed is the best and without running power straight of the barrel, plus it has a good power source as well. Ive placed ground onto the battery as there wasn't any power loss between there and the ECU ground which is close by.



Now that’s done and fused I'm ready to move onto splicing the sensors I want from the ECU. I wanted to grab TPS, STPS, Gear and Water temp. Since I found out that the R6 doesn't have a variable gear sensor, I decided to leave that and tap the TPS's and RPM. Ive also left water for now as well, but will tap later.


Here you can see I basically strip the wire back from the loom and splice the data loom into it without breaking the original loom. The Denso ECU uses the same connectors as the MoTec 100 series so I basically already had the knowledge of getting pins out to heat shrink and secure the wires.


As I've noticed for the wiring diagram (Thanks Tony), Yamaha like to use the same colours and size wire for different things. This is something I noticed when installing the Shift I to the bike, they use the High beam activation (which is ECU controlled) and RPM colour. A simple continuity and voltage test had insured me which wire was which for RPM and also TPS, which had two of the same wires to the ECU.




Basically, after that was to check power and voltage levels to the unit and to install the GPS. For now I've just placed a steel wash under my pillion grip rubber and it works fine. I haven't tested the GPS yet and if it falls out of range whist leaning, then I do have one of the Moto GP antennas that are designed for bikes.


Upon looking at the data, everything is working well. I haven't test ridden the bike yet, but will on the way home. All I want to do is to install the remote logging and status light button. It basically gives me the ability to start and stop logging and the button has a status light built into it. I could set the unit up to start recording under a variable condition; ie RPM > 1000 for 5 secs and stop rpm < 1000 for 30 sec. But I'd rather have control over it. I will put the button near the dash.

So, here we have is a system that will basically do the following just by giving it power.

  • Speed via GPS
  • Track mapping with Google overlay if needed
  • Accelerometer measurement in 3 axis at 2G, upgradeable to 6G
  • Gyro, as an upgrade

When hooking the system up to sensors we can add more variables.

  • Temperature
  • Pressure
  • Linear, Suspension Pots
  • Infrared or height
  • Angle and position
  • Steered angle and loads cells

All of this at a starting price (that could be installed) for $1500. Package includes DL1, Connector and power plug, GPS Antenna, Mounting tabs and Software.

I will keep you updated on the progress as I play with it more. I will also be adding the new Video4 system that has the ability to log 4 cameras with all the information from the DL1 via a serial connection. So I can design my own Screen template (in fact I have the Moto GP template) and show my data over the video. These units are normally around $ 2600 for a 2 camera system and $3400 for a 4 camera. But state of the art and used in a lot of top end racecars around the world.

And no I’m not using this as a sales pitch – but I’m sure people would’ve asked how much and where do you get them from.

Cheers

RE: Project - Data logging your Race bike

:drool:

You're a bastard.

So what resolution would those cameras be? :blush:

Also, how much would linear pots and another wheelspeed sensor be and can you interface it directly with the DDA port on... say... a 1098? :dodgy:

I know this is one of those gadget you want.

The VIDEO4 records at D1 resolution; which is the same as that used on DVDs and broadcast video. For PAL this is 720x576 and 25 frames per second and for NTSC this is 720x480 and 29.97 frames per second.

High Resolution Camera
The VIDEO4 can use up to 4 composite video cameras to record video from. With a resolution of 540+ TV lines and using a 1/3" Sony Super-HAD colour CCD combined with the excellent Sony HQ1 chipset, the high resolution camera is ideally suited to capturing the main D1 resolution video. The Super-HAD CCD used in the camera is designed to allow more light to pass to each pixel, giving increased sensitivity and reducing noise. Cameras are supplied ready to fit to our VIDEO4 system, with a 2.0m long cable and VIDEO4 specific connectors.
The high resolution camera comes shipped as standard with a 6 mm (53° angle) lens

The high resolution camera is housed in an IP67 sealed robust aluminium enclosure. The camera measures 21mm (Diameter) by 90mm, and features a 1/4" -20 standard tripod mounting thread for compatibility with our suction mounts.

Standard Resolution Camera
The VIDEO4 can use up to 4 composite video cameras to record video from. With a resolution of 420 TV lines and using a 1/3" Sony Super-HAD colour CCD combined with the excellent Sony HQ1 chipset, the standard resolution camera is ideally suited to capturing the additional picture in picture scaled videos (because the PIP videos are scaled down, a higher resolution camera does not offer any benefit). The Super-HAD CCD used in the camera is designed to allow more light to pass to each pixel, giving increased sensitivity and reducing noise. Cameras are supplied ready to fit to our VIDEO4 system, with a 2.5m long cable and VIDEO4 specific connectors.
The standard resolution camera comes shipped with a 3.6mm (90°) lens.

The standard resolution camera is housed in an IP67 sealed robust aluminium enclosure. The camera measures 20mm (Diameter) by 78mm, and features a 1/4" -20 standard tripod mounting thread for compatibility with our suction mounts.

:newspaper:
I don't think we could use the DDA system, but we could surely use the OBD system. I'm currently help set one up on the New Aprilla RSV-4 in the Aust Formula series. But I could look into the DDA system to see if it's Serial protocol or OBDII.

Linear pots that we sell for moto use are around $ 380 each for the same units the Superbike and some Moto GP guys use. I'd just use your rear wheel speed sensor against GPS to calculate slip, but this can be done anyway with a Gear sensor and/or gear ratios against RPM. I will hook my speed sensor up as well, but mine is gearbox based unlike yours being in the rear wheel. But with sprocket changes the gear ratio is a better option and GPS in not affected by this.

RE: Project - Data logging your Race bike

I don't know whether the DDA port on the 1098 only spits out data when the dash dictates or if its on the bike databus but I think the 1098 is CAN so it might just be plugged into the main bus with a signal to start and stop data recording? :D

RE: Project - Data logging your Race bike

The DDA is USB though. So I need to workout how the data is stored. The bike would still have can anyway. I think the Dash turns the DDA on or off and you can wipe the data from the Dash on the DDA as well.

RE: Project - Data logging your Race bike

Is the DDA plug USB though? I know on the monster you can trickle charge the bike through it, so it must be running 12V instead of 5 there...

I had assumed that the DDA stick just got an instruction to harvest information off the bus and from then on just picked up tagged info that would be passed backward and forward from the ECU to the dash anyway...

I guess thats where those sayings come from about assumptions :blush:

RE: Project - Data logging your Race bike

No the Monster has the trickle charger on the left side near the trellis frame, it's one of those male/female combo plus that Bosch used to use. You disconnect it and then run the charger straight to the battery. I know the 696 does and so should the 1100.

I'm sure the DDA is a receive only serial unit, but I'm not sure how it's powered. If it's two wires then you would think it was RX and Ground. I can't see how Can would work as that would be Can high and Can low, but still no power.

I might call my friend at Magnelli Marelli and findout. Or look at Google later.

I just checked mine and its 4 wire 2 power and 2 other, not sure about the rest though. The trickle charger do M1100 thing I was told by a friend who works at the Ducati store (Rob). Aparently it doesn't work with the 1098, but on the 1100 it does...

TBH I'm not sure how the whole thing works, so far I'm full up on assumptions, but I'll have to do some reading :D

RE: Project - Data logging your Race bike

So your DDA have four wires? Four wires would make more sense to Can or even Serial. Maybe even OBDII with TX,RX, GND and power for the unit. I'd still say it's 5v though

It should be located under your seat on the Monster. I will look at Sam's tonight. She will probably hide the keys in fear of me taking off on it again.

I did tell her it needs a Shift I. Somethings your's really needs - especially if someone rides it, who is normally used to 16,000rpm of madness:drool:

RE: Project - Data logging your Race bike

So I stayed back at work to finish off the main install. It basically was hooking up the Speed sensor to calculate slip in raw data and the remote logging button.

Here are a few more pics of the remote button install.






The remote button is the red button on the alloy bracket - which I haven't painted yet.

I will upload some screen shots of the logging soon.

RE: Project - Data logging your Race bike

I had the 430 Scuderia GT in here last week - but didnt get a photo next to my bike. That said, I did get photos.

Personally I think the 355 Spyder in gutlass and a heap of shit to get complianced in Aust. I'd rather a 4200 Maserati anyday. It has the same engine and gear box package but with more punch and better looks.

Just looking at the data now. I'm super impressed. These bike hardly ever got full throttle with the ECU controlling them. Will post results soon, you will be amazed!

RE: Project - Data logging your Race bike

Ok, I’ve played around building up a few templates in the Analysis software to get some info on Speed, Throttle and Lean angle on one corner (slightly damp - before you mention anything).

Below is a picture of the Speed trace with GPS and Driven speed. You may notice in this particular section the difference in the two. One is due to the GPS just slightly missing out at 180 kph, A few more tweaks and I should have that sorted, but you will notice the gear changes and slight wheel spin. Most of this is the bumpy section of road and also the initial moment of getting on the brakes hard for a few seconds - resulting in the rear wheel getting light.



I did some moderate brake testing this morning and have seen 1.4 to 1.5 g braking forces with semi cold tyres and not a lot of finger pressure. Track testing will see better results. With a Linear pot of the front and rear, we can establish the maximum braking point for the bikes setup. But more on that another time!

Below is a Throttle trace on another splat that was done. You will notice again two traces. One is the Throttle input and the other is the actual ECU controlled output. As this bike has Drive by wire (or ride by wire in bike terms) it uses a potentiometer to measure the throttle in put from your wrist (Still cable driven) and then the ECU controls the stepper motor on the throttle bodies.

This test below was to see how fast and close the two work together, On the Suzuki engine we have, we have noticed a huge difference - I feel it’s set on the wrong throttle map. However the 08/09 Model R6's have a very close 1.15:1 ratio on initial response! The throttle difference is basically an equation I put together to show the rate of change between them.



And the final was just an example of a roundabout taken at 270 deg, basically it shows how well (or how not well in moist conditions) the lean angle and be calculated. The R6 does have a lean angle sensor, but I think it is only a mercury switch ball system to shut the engine off when you drop it. So I haven't looked into it.

The map is coloured with a speed variable and the throttle position has speed against it to show you the transition of throttle to speed. You can see how much speed you can pick up just in a small amount of throttle of the apex of the corner. To be honest, it's a very good example of how you should be getting on the power out of a corner. A fast smooth transition to keep the bike stable and keep a constant wider contact patch with the rear tyre.

And yes Drew! It is that corner that your Ducati just didn’t do it for me:nod:




Once I have a bit more testing and some input I will be able to take it to the track.

Is there any sort of variable or logging that someone would like to know about? There are a lot more math and user channels I need to setup before I get anywhere near the ability of this amount of logging. A few more sensors and then the intergrated video will be perfect. Basicially the Video is sync'd to the logging frame by frame. To save money, third party video can be intergraded with a video licence. Then you can make your own video with the variables on the screen, Speed, TPS, RPM and of course Lean angle.

RE: Project - Data logging your Race bike

Thanks Bluey and Drew.

Ive done a fair bit more work and now have a few more inputs to play with. The lean angle and GPS is working extremely well and accurate. I've also got the maths equations sorted to workout Drag and Aero cd, which in turn can be used to calculate power and torque. Very hard to get close to right on a bike, but if I can nail that - then I can nail an open wheeler racecar. The software can also calculate with a simple netrual roll at 100 kph.

Hopefully tomorrow I can do a short video on the way to work to show the results. I've also got a few other things I can play with with testing as well, including the new RF rejecting GPS antenna. This should boost my GPS Acc Position up a fair bit, but only testing will tell.

So far I've only managed to do Yarra Bend to get some twisty data. Hopefully this weekend I will have the video finished and all the channels finished. I can either use my Go Pro Hero camera or try to incorperate the Video4 system which can run widescreen and wide angle lense if needed.

Keep you posted.
