Ok.Atessa has nothing to do with the engines ECU. The 4WD has it's own ECU.
I wouldn't question why you'd like to bother with the Autronic
Wrong.Atessa has nothing to do with the engines ECU. The 4WD has it's own ECU.
Just tried to call you. Got your number from LarsWrong.
The Atessa ECU need to communicate with the engine ECU.
Autronic is FAR FAR better ecu then most on the market that are plug`n`play for skyline.
The best thing about it is, it uses a cranktrigger for crank position, and not the CAS.
He must have done something very wrong.Although the engine and 4wd ecus are separate, there are shared sensors between them. Now I read that on some aftermarket ecu setups the shared sensor's voltage is reduced by the aftermarket ecu, which isn't a problem on stock ecus.
This causes the 4wd ecu to go into rwd only mode.
I can't remeber how to fix it specifically, but if you try PMing dirtgarage on SAU, he sorted the issue for his vipec ecu
What part of the wire loom do I have to leave in the car?Ok, I stand corrected. There seem to be some wires that need dealing with. But as I thought (and remembered), it isn't exactly rocket science.
Most people think that the Atessa is build into the engine ECU, so is removed when you change it for something else. This is wrong and thats what i basically tried to state.
In other cars ive built, we have removed the whole engine loom, abs loom.What part of the wire loom do I have to leave in the car?
Can i Take it all out and just use the wires to the atessa ECU?

You just keep all the wiring for the atessa system, abs sensors, g-sensor, and give the atessa ecu tps + - and rpm.
If youre not completely comfortable with wiring, and electronic diagnostics, it can be a pain in the ass :chairshot
