LS4 TB installed...codes
I installed my NBS, Cam Gears, TVS, and LS4 TB last night. I have the following codes:
P0507 Idle Speed High ECM, PCM
P1516 Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance- ECM, PCM
P2119 Throttle Closed Position Performance ECM, PCM
Sorry for the noob questions...been out of the car scene for a year now....
My question is when I re-timmed tht engine do I have to do a case relearn? The PCM is the same and don't get the CASE relearn code but I get alot of TB codes. I solved the P0532 and P0068. I'm wondering if the TB is a lemon or I need to relearn.
BTW: I changed the P0068 to 8000 RPM to solve that one. I increased the other one (can't remember right now) to 4500.000.

you need to change something in the pcm for the ls4 throttle body. im not sure exactly what it is (scalar factor or something like that). if you didnt it may be whats causing the issues

if your idle etc scalar is set to 4500.000 then i have no idea what to tell you
check all your connections again, i had a vacuum hose or whatever it is blow off on mine one time
was your ls4 tb used or new?

I'm not sure what pulley I have on but.......I hit 23 PSI! I have a much smaller one but decided to go with the middle size. the boost guage maxes out and starts to go below the "boost" writing then freaks out and resets! Car pulls wicked hard!

Cool....well I know I have the 2.5 and the 2.75.....lsjwannabe what's the other size I have?
60lb injectors are at 110% 17* and scan guage reads 449 hp....I KNOW IT'S ONLY A SCAN GAUGE AND NOT ACURATE...SO DON'T FLAME ME!!!! When I come home for good in Feb I will get a better tune and real dyno numbers. I really want to hit the 400hp mark with a SC.
