Serious Issue

'The ECU wants to see 0.63v from the TPS sensor when your foot is off the throttle and greater than, say, 4.6v when you're fully on it. You can datalog TPSvolts to see what the ECU is really getting. The value at idle (foot off the throttle) is probably more important than the value at wide open throttle. A value that's too high at idle can prevent the idle switch from activating or it will prevent the “simulate idle switch” functionality from working properly.'


Hopefully somebody will correct me if that is wrong or doesn't apply if he isn't using link...

Thanks for the info! Hopefully somebody will reply to what you said haha ;)

Just start from scratch and get this thing setup correctly for starters. Adjust your tps exactly like brad wrote. Set your base timing and idle properly, refer to vfaq if you don't know how. Verify your idle switch is working. Verify your isc is working. Get a bypass plate to block off the fiav to rule it out, plus you will never have to worry about it again. No idea what injectors you have but ensure your injectors settings are decent. Make sure your o2 sensor is working, or just force it into open loop.

Hooked up a scan tool today. Adjusted the tps to 0%.. air/fuel is a little better not 100% idle is sitting at 12.8-13.2 and cruising its at 14.8-15.2... ideal would be idle n cruise to be 14.2-14.6. Still gotta do a boost leak test and I did not install the bypass plate yet. My tuner told me idle should be at 5% so after I do a blt I'll adjust the tps to 5% n see what happens. Scan tool only shows % not volts. O2 sensor and maf sensor seemed be to okay also.

I run a bypass and mine works fine

So that didn't work.. I took off my TB again and gonna install that bypass plate.. Do I still use the o-ring gasket with the plate? and do I use some sort of sealant with the plate on either side?

Even with the bypass plate installed im still having issues with it running rich but it is better than before. It'll run good for a awhile then go rich again, So I'm thinking it's the tps, Still gotta adjust that to the right %.. Hopefully I can get a tantrix cable hooked up and get more in-depth with it and see what's going on.
