DOHC ZC Turboedit, Engine Problems
Okay, I really need help, I'm getting nowhere. I'll just tell the whole story to make it easier:
It's a DOHC ZC, built (forged pistons, skunk2 intake, sleeved block, etc..), it's in NA form right now. I put it in a couple months ago, did a quick tune on turboedit with a PR4 ECU. It ran good.
I decided to put my Delta 272 cams in, but first I hooked up my Hulog to make sure everything was working. It was working fine. I then installed the cams and my LC-1. I calibrated the LC-1 correctly (programmed it at 0.1-3.80 volts, because the wideband signal goes through the stock O2 sensor wire). It would start and run very rich and would not want to idle. I first noticed a vacuum line that broke and replaced it and checked everything else. It still wouldn't idle and run extremely rich like 10:1-11:1, and then the CEL came on for a TPS.
I noticed that even with my foot on the gas like 10-15% (so it wouldn't die) it would say 44% for the TPS on ECUControl software. I checked the voltage range on the ECU control and adjusted them to fit with the TPS voltage. I checked the voltage at the TPS and it was 0.45 volts at 0% throttle and it had the 5V and a good ground (30ohms of resistance to ground) and 4.40 volts at WOT. I checked the voltage at the ecu (inside at the terminals) and they were the same, but for some reason the ECUControl thinks it's almost always at 44% throttle(sometimes it acts normal for a second or two), and the ECU itself thinks the TPS has something wrong. I really don't know what to do, I know it's running so rich because it thinks it's at 44% throttle all the time and it won't idle. Any help is very appreciated.
