L36 pcm in a L67 car



besides your PCM not knowing what to do with the boost, not being able to control the boost bypass valve, the wrong gear ratio in the trans files, the wrong injector sizing, the excessive WOT timing you'll be running, etc...?

a lot. how is the car even running?
 
Yeah, it certainly could. The excessive timing could very well blow a piston, and the fueling is doing god knows what with faulty MAF and MAP readings and injectors the wrong size.
 


how is it running? my car was running so rich it barely would stay running when i went from 33# injectors to 43#s
 
Wow. This is good info. Thanks guys.

1 more question.

If a rod or piston is thrown or damaged, what part of another used engine should i get to fix the damaged engine?
 
To do any serious damage, you would have had to have driven it fairly hard. As badly as that thing had to be running, I hope you didn't do that. Thinking back, since you had the L36 TB on there, your MAF calibration would have been right. This means the only MAJOR problem with it even running was the injectors. You were running incredibly rich. This won't usually destroy the engine, although it'll do in the plugs, cat, O2 sensor, etc.

Did you happen to notice any fuel pouring out the tailpipe? :)
 
No but i was misfiring on cylinder 6 and had 3 codes.

1. p0306 - cylinder 6 misfire
2. p0036 - H02s heater control circuit
3. p0449 - evaporative emissions system vent valley solenoid circuit.
