K, so found the problem, i when i soldered the new connector in, i crossed VTA and VC. But, when they were crosses, the car seemed to pull harder, ion first it would break the tires loose as soon as it hit boost, and now it does not. It just seemed to have more power when the wires were crossed. I know its because the tps signal was very high, but what does this cause, timing advance, more fuel, etc?? Thanks
Both. With VTA wide open the mixture is near best power versus stoichiometric where it would normally be just before boost comes on. Can't leave it like that though. With full on VTA at idle exhaust CO is about 4%. Emissions and fuel economy would be in the toilet.
Okay, so basically it just spiked the AF Ratio? I just drove it again, and it had noticeably more power when Vc and Vta were switched. What needs to be adjusted? Thanks
