Title: Heat Warning
Post by: MaddogRX7 on April 28, 2005, 12:03:08 AM
EVERYTIME THE SECOND TURBO KICKS IN THE HEAT WARNING LIGHT COMES ON AND I LOSE POWER. I ALSO NOTICED THAT THE INJECTOR DUTY AFTER THIS HAPPENS IS RUNNING AT 0%

ANYBODY GOT ANY IDEAS WHAT THE PROB IS?

If i quickly flashes is it your knock sensor detecting a Detination.

If it stays on for a while i\'d say your hitting the Boost cut. (Especially if it kill fuel aswell)

Try lowering your boost with a controller or upping the boost on the commander. (Lowering is better btw)

Sounds like you\'re getting a boost spike as the second turbo kicks in.
The PFC will cut fuel if boost goes .25 Bar above preset level. Do you know what boost and duty settings you have? You can also set PFC to show what you\'re max boost hitting.

check on the pfc if any of the sensors has a problem..dracos car had light coming on as he accel in 3rd at 70mph and pops and bangs and it is the throttle postn sensor voltage fluctuating..the sensor is vta1 and vta2 in apexi
