Exactly as it was wired in at Snetterton.

You got some screenshots then? I think I've looked at the manual for general GEMS canbus setting up, it's quite comprehensive in itself.

What you need to remember with signed values is you are losing 1 bit of range to give you the signing, so a signed number sent with only 16 bits will be a 15bit number and a sign, which in effect is the same overall range as you can go from -32768 to +32768. You can use you're maths function to deco...

The compressor is ONLY activated by the ECU. You turn the switch on in the car, if there is enough pressure in the system it will then send a signal to the ECU, which will raise the idle and perhaps turn on a fan and then turn on the compressor. If the gas is low, you can turn a/c on but the signal ...

The factory car will do this, as the A/C system has it's own temperature regulation in the evapourator (cooling bit). You need to check the status of the A/C system when it's doing this as it may not be the Syvecs at all. Also make sure the system has enough gas as low gas will cause the output from...

I would prefer to have the ECU in direct control of the ignition and fuel, I don't think the racelogic can't do any retard either. But I dare say the racelogic is easier to get running and working to an acceptable level, the Syvecs will require more thorough tuning for sure.

It sounds like you are missing something here. Look at "CalSwitchV" if it is above the top threshold in position 8 you WILL be in CAL08. However there is one thing I thought, you need to do a "Device->Program" before the cal switch thresholds are used, so you need to set them pro...

I don't think you're lambda will react fast enough, and with large transients from low RPM you will probably get a lean spike due to a momentary loss in atomization. Suddenly you're putting a lot of extra fuel in but the airspeed is quite low, compared to say 4000rpm and 0.1bar of boost. You should ...

You are correct in your assesment of what is required. CAL01 = 0.015V - Thresh01 = 0.3v CAL02 = 0.61V - Thresh02 = 0.9v CAL03 = 1.23V - Thresh03 = 1.5v CAL04 = 1.83V - Thresh04 = 2.1v CAL05 = 2.44V - Thresh05 = 2.8v CAL06 = 3.08V - Thresh06 = 3.3v CAL07 = 3.71V - Thresh07 = 4.0v CAL08 = 4.28V But re...

There isn't a document per say but I can tell you how to structure the can. The custom can is configurable and has 4 16bit words per frame. There are 20 frames, with offsets that start at 600h by default. Each word is spat out in motorola sequential byte order. I can be more specific with a little t...
