Friend of mine sold his Autronics ECU due to not having any quick and cheap way to tune it. Trying to convert back to stock and looking for info on what all needs to get changed back over and so on. Noticed a purple and pink wire seemed to be swapped out on the car's wiring harness at the ecu.

 

I think you need to swap the fuel pump wiring. You can do this by swapping A22 and A8. For full details download the manual from the following link and check the section about immobilizer:

Also make sure the stock resistor pack is actually wired up proprely so that you don't fry the stock ECU by driving the lowZ injectors directly.

 

Any more info on this^ didn't see anything about that in the manual so far.

 

so today i went and tried again after nasty and tyler addressed the wiring issue i engaged the pump with evoscan it worked fine ,
we unhooked the fuel line turned the key to on and cranked it over fuel shot out ,
still wont start ,, i already disabled the immobilizer the proper way ,,
the car will sometimes fire but not more then 2-4 consective pops and thats it .

 

The resistor pack is located on the passenger side firewall on the engine side. A picture of it can be seen here.

On some standalone installations with big injectors the resistor pack is bypassed to allow peak and hold operation instead of saturated (as used by stock ECU). Just make sure that this resistor pack has not been tampered with (i.e. all 5 wires shorted out to bypass the resistors).

I can't think why the car won't start, especially if you did the immobilizer delete thing with the code. Since pump runs then you have the wiring spot on. If you're using non-OEM injectors make sure they are low impedence (around 2 ohms).

 

Thank-you very much well try this next^^^

 

We flipped the cam angle sensor trigger 180* and the car starts now but it's giving off 2 crank sensor DTC's now. Will the 4g63 run if the cam angle sensor is 180* out of phase?


Edit.. I found found out the proper way to install the trigger. It is current installed correct.
