Where Is That Damn Auto Ecu Mounted?

[CruiseLiner]

hey guys anyone know where the auto ecu is? ive found the attessa/abs ecu at the passenger side cargo area behind the panel on the side, and when i traced the wiring from the auto plugs in the engine bay it joins with the factory harness that runs under the dash near the drivers feet area, so maybe its under the dash, though i have ripped that apart previously and dont remember seeing it?

cheers

There is no separate auto ECU, it's incorporated into the main ECU

Is this why we apparently can't use Power FC's in auto Stagea's?

Mine has been converted to a manual, so would this still be an issue, or is the ATESSA also a problem?

There is a few "tricks" which can be used against auto ECU's to run a manual gearbox, but it cant be done the other way around (trick a manual ECU to run an auto)

If you are converted to manual, you wont have any issues (but one) to run a powerFC. The issue that i came across was the ecu plug on the engine harness. Now, ive HEARD and mercury said they could supply me a power FC to use the stagea harness, but i assume this was a r34 GTT one. Well, there is differences in VVT 33/34, so i dont know how good that would work and ska doesnt know what model PFC is in his car.

I have bought a r33 s2 stock ecu with the plug from japan, ill chop the engine harness on the stag and the replug it up, to suit the r33 gtst PFC i have.

The attessa ECU only needs a few ecu outputs, which are on the gtst anyway. (engine throttle position, car speed and something else)....sooo in theory, my method will work....just need a damn gearbox now !

attessa has 3 wires to the main ECU and they are:

engine speed signal

throttle signal +

throttle signal -

thats about all i know, and im trying to work out whether mine is hooked up correctly with the Autronics smc ecu installed.
