SV: VS: MC2 running very lean

[Dag Bøsterud]

I ran the car without the OXS today. No change what so ever :/ Ran just as
shitty. The car runs just the same when cold, although I don't floor it when
it's cold, but as mentioned before it will start to misfire before the turbo
kicks in.

 

I ohmed the coolant temp sensor for the ECU when the engine was hot, and got
about 89 ohms. This should be okay, Bentley book says 60-1000 ohms when
coolant is 20 C (68 F) minimum.

It is possible the ECU is bad, but I'd eliminate everything else first. Have
you run it with the O2 sensor unplugged? How does the car run when cold?
Have you ohmed out the Coolant temp sensor?

I've double checked everything once more. I'm lost. I really can't find any
clue as to why it's running so lean.

 

What about the ECU? I have a chip from Ben Swann.
