Just wondering if any of the people out there who know about computers could offer me some suggestions/explanations?
Ever since I did the EECV conversion the car has been seriously overfueling - to the tune of about 5km/L.
I wasn't too worried, figuring it was just a sensor.
I have since replaced TPS, MAP, and O2 sensors with no effect. I have checked the regulator, that's OK, am basically stumped now. I will try testing the coolant sensor tomorrow but I seriously doubt that would cause that sort of overfueling. Basically I am down to computer faults, or wiring faults.
Now I did not touch any of the sensor wiring when I did the job, so I don't think it's that, but if all else fails I'll have to pull it out of the car and go over it again.
About the only lead I have left to try is: Can anybody tell me what the black/white wire is for which connects the TPS, MAP, O2, and P/S? Various different books tell me it's a common power, common earth, or data bus. Neither of these really make sense to me due to conflicting apparent functions on various plugs.
Haven't been able to get a reading off it with the analogue voltmeter, dunno if I should though so this is not much use to me.....
