Sounds like your injectors are maxed out mate.
Whats you duty cycle show under the monitor section ?

the omp is down at the bottom of the engine, on the front. Just next to the bottom pulley from memory. The wiring is all on one multiplug.

Put a stock ecu back on if the omp has failed the ecu will go in limp mode.

Hello Brian, we already tried the stock ecu and it was running fine with it. The vmop is highlighted on the sensor screen but only when it\'s between .40 and .80 and goes out above this voltage. I gave lrp a little premix to be on the safeside untill we figure out why it\'s doing it. Thanks, Greg.

Had similiar problem with mine years ago,it was an oil leak from turbo return leaking over electrical connection on metering pump.This caused a change in electrical resistance which caused the fault.Fixed the leak,cleaned the pump connections and everything was fine.
