I found this in the AEM bible, thought you would find it interesting. Pressure (huge throttle plates or a positive displacement supercharger), you may Measuring the dTPS, you can judge how much extra fuel would be required.Īlternately, if the dTPS does not give a good indication of the change in inlet Reason, there is a 'decel pump', which, acts opposite as the accel pump. Vapor and small droplets of fuel being carried by the air stream. Liquid fuel that is on the intake track walls which travels much slower than the fuel

Stream at the injector and the fuel flow past the inlet valve. The primary reason for this is the time lag for the fuel flow into the air Requires a change in fuel requirements, beyond that dictated by a simple air-fuel ratioĬalculation. The idea being that a rapid change of pressure in the intake system Position (dTPS) and delta-load (dMAP) components. Support gives the aftermarket the push.The AEM EMS has a traditional accelerator pump which consists of delta-throttle Hell, if I have to go with an aftermarket turbo, then let's go. Geez, you can't even combine mod's without doing your own custom tweaking with HPtuners right now. I don't want a tune that needs to be custom changed for every bolt-on by shipping the ECU back, nor having a tune that is only good for a stock motor with no other updates, nor by having a module hooked up all the time to read all of the motor functions and tweaking the motor functions myself with software. It is too much to ask for 350 hp (crank) with bolt on's? I'm thinking a truly cracked ECM (something that has a database of programs for mod's), exhaust, IC? I'm still waiting.Ĭ'mon, let's crack the beast within. Give me an honest 350 hp at the crank in the GXP and I'd be happy. Well, I've been sitting here with my GXP now on 7 months and watching the aftermarket for a full year with this car.
