Okay, I just got through firing up my SR20DET after putting the Enthalpy tuned Ecu on the car. It starts fine but is SUPER rich. Plus, when you take it for a spin, the minute you give it gas, it sputters because it is so rich. I checked the Injectors, they are not leaky and are all working. The only other mod I did before this was the Z32 Maf. I'm pretty damn sure it is wired correctly. Any idea what to check? The car did not do this before the 550cc Injectors, Z32 Maf, and Enthalpy tune..Suggestions welcome.

sounds to me like either your maf s wired wrong or rou have a bad MAFon a side note....(scott) knows these ecu's so well that i would not even think of a possibility that he made a mistake..when you had him retune your ecu, did you tell him everything you have done to th car as far as upgrades..injectors, MAF.etc.

Yeah, I did let him know all the mods I had. I'm guessing that the maf may be wired wrong even though all the volts read out right on the correspsonding wires...I'm just not sure. It's just DUMPING fuel. So much you cant drive it because it just sputters as soon as you give it gas.

True, I'm in the process of looking for another one. I did unplag the Maf while it was running and it did not make a difference. I also switched the wires around and it was the same, so, I'm not sure. I would hate to buy another maf and that not be the problem.

well hopefully you do have a buddy near by you or maybe a nico brother soemwhere close so you can do the swaparoo. if you have no luck in doing that than i do have another z32 maf that i will loan you...i can send it to you, but i will most definatley want it back

ps if you do need my maf then i will ask that you send me a little money for the shipping at least for the trip to you

I would Def send you double the amount of shipping if need be. I def appreciate the offer. If I can not find another one, I will look you up! Thanks again. I am desperately trying to get this thing running properly. It should be a very streetable beast.
