your ecu could be toasted.
switch ecus and see if it changes anything.

tonyxcom

damn. I'll try that once I find another ecu.

thanks

Kamin

no problem
in the meantime
check the ecu fuse. (under the hood big *** fuse in the main box, cant miss it)

tonyxcom

yeah it looks fine. I have had it unplugged for the last 30 mins while I get some work done here at the computer.

I am bout to go plug it back in and see if it changes anything, which I doubt it will.

Well, I put my stock CX ECU on, and the car wouldn't idle, but it did throw codes.

I also went and picked up a JDM ITR ecu from b18c_powered_si, slapped it in, and guess what, NO CELS!

Drove it around the block, let it idle for 5 minutes and still no CEL's. Hopefully it will stay that way.

So now all that is left to do it get a cat sqeezed between the CTR cat back and the US ITR manifold.... And I can begin the break-in process.

I heard the jdm ecus dont throw the code 91, but if it does then it wont throw it for a couple of days I think the reason your car died when you installed the cx ecu is because the iac wasn't wired properly because of the ex harness your using. The ex harness is set up the same as bseries for the iac.

That is probably it. Suprisingly, there was a very strong smell of gas in the garage after 30 seconds, leading me to belive the CX ecu was actually making my motor run rich.
