Standalone in 993
 

hello from Poland!
Its difficult to say straight what for but I decided to install standalone system in mine 993. Motec to expensive, Megasquirt.. rather not.
I decided to install polish ECUEMU system - advantage? costs, documentation and smart people to do a job. Standard brain cables with connected to that ECU system. Later on photos. This car is ex USA C4 (currently C2 :) ) with Motronic 5.2 & 88 pin system.
Still have a problem with:
- blinking immobiliser light
- ABD red light
any ideas which pin is responsible for above?
with pleasure I will consult maps
photo from last track day - do you recognize a place?
thanks
Marcin

I have installed standalone (VEMS) on 993 '95 (with 55pin Motronic) on the factory harness as Plug'n'Play.
Getting rid of ABD light required feeding pin52 (marked as "PWM" in factory manual) with TPS signal in PWM mode (not analog 0-5V mode). I used boost controller output for that and configured the outout curve just as linear relation to throttle pedal position. Seemed to work fine and no annoying lights.

Can't help you with the immo light other than putting a black tape on it or pulling the bulb :)
You have to study factory wiring diagrams and experiment a little but my guess is that the immo communicates with the ECU via CAN bus or K-line. Might just buy an immo emulator from ebay for few euros and try.
