I got the KB installed...not too bad of a job but a couple things turned out to be PITAs...like the blower to intake bolt right under the plenum...never did get that thing tight enough. The vacuum lines as well. I should have put the vacuum line into the boost bypass before putting the blower on as it was not fun finagling that hose into that opening.
Another issue is the car doesnt idle correctly. I bought a new LFP SBTB and it looks like a nice piece but the blade wont close completely...or I have TPS issues. When I open the throttle and just let it close on its own it will not idle back down to 850...it stays around 1200-1500. I can manually push the blade closed and it will then idle correctly. Is there a way to tighten the spring on the TB? Or is this a TPS issue? I tried to datalog the TPS voltage using only the xcal3 but I am not sure if what I was doing was correct. The idle TPS voltage read 203v...I unscrewed the TPS and turned it clockwise as far as it would go. The datalog reading only changed to 195v. Any ideas? Thanks.
I tried doing the method Doug at BF suggested but it didnt work...
1. Warm up car
2. Turn engine off and REMOVE THE KEY
3. Disconnect negative lead from battery and turn head lights on( this removes the capacitive charge in the system)
4. Connect negative lead to battery
5. Back off the stop screw on the throttle body
6. Start car
7.While grasping the throttle lever with your hand, give it a small amount of throttle and let off SLOWLY.
8. Adjust the stop screw to just meet the lever and give it another 1/8-1/4 turn and, then lock it down.
9. Turn ignition off.
10. Turn key to "ON" position and check TPS voltage.
11. Turn key off.
12. Repeat steps 1-4 to reset ECU.
13.Drive car as you normally would so that the ECU can relearn again.
So the only change I made was adjusting the set screw to where it touches the blade stop. It still reads 203v on the TPS and the idle is still around 1000. It threw 2 codes due to this as well...p0511 and p0507. I cleared them but they will return if I dont get this fixed. I guess I could put the set screw back where it was and put a second spring on there...
