Re: ls vtec with a pr4 ecu with a msd rpm activated switch for vtec (GOLDBERG)
on a VTEC ecu, there are two separate fuel and ignition maps. one for the nonvetc part and one for when VTEC kicks in. when VTEC is on, the car puts more fuel and more timing into the motor. the LS ecu only has one set of fuel and ignition maps so u risk the chance of running lean.
just buy a P28 ecu and have it chipped with a GSR prpgram or have someone make and tune an uberdata chip for u. u will most likely need to run wires from the ecu to the engine for the vtec solenoid and VTEC pressure switch, since ur friend ghetto'd his ls-v setup
