OK here is the deal.
I have a 2G. Full race motor and P&P head with 1mm oversized valves. 750cc injectors with a PMS to control them. Also I have a TMO stage 2 ECU.
Now what the car does.. if I try to rev the motor up and hold it at a steady RPM or I try to drive the car. The motor will rev up like it should
but the all of a sudden it will cut the fuel.
I know this because the injector duty cycle on the PMS pad goes to 0% when this happens.
I can't figure out what to do. Any ideas.
One weird thing that I noticed is that the TPS load on the PMS goes from idle to high part throttle to WOT. There is no low or medium load that ever gets displayed. I have checked the voltage at the TPS sensor and I get the 4.5-.5V like there is supose to be. So I know it is not the TPS sensor. (I also tried another TPS too)
