I just bought an S13 240SX w/ an S14 SR20DET swap. This has the stock MAF and (I think) stock injectors. It runs really rich and has problems idling/running when it is cold, once it warms up it still runs rich but it runs pretty strong.
The ECU already had a nistune type 3 board installed so I hooked my laptop up to it today and let the car warm up to get some base readings and see if I was throwing any codes.
I was worried about the RED for the VTC Solenoid, Fuel Pump Relay, and TPS Idle until I read in the Nistune documentation that it was normal (odd color choice for normal).
I am a little worried about the Knock Sensor Code and the TPS voltage being so low, I was under the impression it shouldnt be under around .4.
Can anybody chime in on whether or not any of this might be the reason I run so rough cold and so rich?
Thanks
