Yeah tyre pressure and maybe temp is something i want to do, but to be able to log it continuously, ie not just take readings in the pits, gets expensive, as each wheel needs a sensor/transmitter, if you have 2 sets of wheels at the track thats 8 sensors, plus the antennas, main control unit ect, prices for a good motorsport grade unit, like the set made by BF1 systems, starts bit under $3k but more around $7k+ for it all, so yeah adds up quick, something i can add many years down the track if i need to, but not high on my list, but in building the wiring now, i have allowed for this, well i have a spare separate CAN and power connector for it or other future devices.


No matter, it at least look very cool! I see there is a M130 available which is about the same price as the Haltech Elite. This is a game changer for a lot of applications. It has croseed my mind to make the change but chances are, I will stick with the current set up.
Great to see you are making your way to the MR2 30th. It will be great to see your car there but doubt mine will be due to its current state being less than yours right now!
Hopefully it will be running for the MTC 2016

with the M130 you would also have to get the GPA or GPR firmware package so theres a bit of money also.

I will not be going with the Motec. Will be sticking with my current set up then decide on a ECU in the next few months.

Ok cool. Well if any of its setup by your track day next year, ill help with what i can.
 
Ok finally had some motivation and spare time, so have been doing a few things on the car.
 
I put on the carbon fiber targa tops i got of Admin ages ago, and today i had a windscreen installed

 
 
Made up a new steering wheel, I had the switch plate drawn up and had it CNC laser cut up (if anyone is intrested in one, send me a PM) then anodized, dropped the steering wheel at the engravers to get all the button labels laser etched onto the wheel, ordered all the Apem waterproof buttons and wired it all up.

 
 
Here you can see the red button shrouds i used for the 2 buttons i dont want to bump by accident

 
 
All wired up, Raychem wire, DR25 shrink and molded boots, all sealed up, also got a Krontec quick release and spacer (spacer was needed for the wiring)

 
 
Krontec quick release with Deutsch Autosport 22 pin connector. 

 
 
Heres the center switch panel thats in front of the shifter that i also drew up and had laser cut up, anodized and writing laser etched. It has the inside switch for the fire extinguisher, main battery isolator switch which is a mil spec / aviation switch, cant be bumped, to switch you have to pull the lever out a tiny bit then toggle up or down, also 9 position switches for boost and traction maps and then the Motec CAN keypad.

 
 
Very simple bracket, nice and light. Using all factory mounting holes.

 
 
Good overview shot. On the left of the dash you can see the 2 connectors for the laptop, ones for the data logger/dash, the other is Motec CAN1 for programming ecu, PDM, LTC ect.

 
 
Also got a Motec SKM

 
 
A SLM, as i realy need the dash were it is to see it, i can see the screen great through the steering wheel when straight, but when turning a fair bit, cant see the lights, so ill have the SLM on the dash above the wheel and set it to mimic the ones on the dash or just shift lights and 1 led for warnings, dunno yet.

 
 
And the Racegrade 20hz GPS as i was talking about.

But seriously. Wow.

There is an extensive build thread for my car here: http://www.mr2australia.com/mr2play/tm.aspx?m=18316

I would have had the traction dial on the wheel and not the start button, but that's just me.
 
Also i think your build is starting to overtake most of the efforts of the guys at Motec's projects.
 
Looking good, i think that is the neatest steering wheel wiring i have ever seen.
 
Are you running wheel speeds to the dash or into the ecu??

Thanks for the complements everyone!
 
Well yeah, my thought was im not sure how often ill use TC and to what level, how well it will work ect, so wasnt a highest priority, start button i wanted to get to easy and can do blind (full face helmet and HANS is bit restrictive looking down low) so put on the wheel so if i spin and stall, which i will, and theres a car coming i can start quickly. Yes i can setup auto restart like some V8 supercars have were i would press clutch and throttle both to 100% to re start if i stalled within few seconds ect.
 
I was debating ECU or DASH, was going to be 50/50, but then when i was thinking TC ive decided all 4 to ECU's 4 DI's, im assuming this is the best way for the ecu to control TC, it means i would be logging them slower then if thay were in the dash direct, but thats not a worry.

There is no harm in running them all to the dash, we even split them between the dash and the ecu sometimes as we have digital inputs used for other things in the ecu (cam control sensors for example.) Also if you have the right help on setup, you can do some really trick stuff with the dash to predict wheel lockups and flash a certain light on a shift light module.

Have you considered consulting a motec application engineer on ideas and how to best maximise your package. I have one in mind that could be really good to help.

And when you are getting to this point, have you considered running a dbw throttle?? You can do some insane traction control when one is implemented, and if you ever run a sequential gearbox, auto blip downshift etc can be setup, getting the most out of the setup.

Thanks, but for a living im a wiring and electrical man, no guarantee any mechanical stuff i do will work!
