OK well I finished my swap, drove for a day and now ECU is in limp mode, will not rev past 3k and no power watseover

The question is I have no CEL comming on and it is certain i am shooting codes, should the light come on or I have to re-wire the PIN's to make the CEL work. I need the CEL to read what codes the car is shooting out.

 

any one? i need to check codes and check engine light no worky

 

On the 2.5 GT Soarer you get the ECU error codes like this: http://www.toyotaimportsforum.co.uk/...ad.php?t=11529

I assume that this won't work for you if you aren't using the JZZ30/1GZ-GTE ECU and I've no idea how it would work on the SC300 dash but you might get lucky!

 

i think ur out of luck man.

 

So the best option is to take it to a dealer pay the crazy 105/hr and let them give me the codes

yeah its a 1JZGTE ECU but my CEL never lit up, It works fine for the MKIII Supra guys, is there a way I can re-wire so I can get the CEL to work, it shouldnt be hard since its just a warning light basically. I have the wiring diagram for the SC300, but for the 1JZGTE ECU which pin outputs the warning signal

 

I've never tried anything with this, but there is a "W- Warning light" pin on the ECU.
