Im giving up.......the car wont run properly

[nismodave]

I cant take it anymore.....

The car will not cold start without starting fluid, and stutters while driving.

I have checked my z32 maf connections, and adjusted my fuel pressure to 40psi, changed my plugs, and checked for vacum leaks.

My car has 550cc injectors and a Enjuku ecu and s-afc. I have adjusted it every which way possible, and even tried my old ecu.

The car just wont run correctly.

I give up.....the car will sit until I can come up with another solution......or take it all the way to FL.

Could the TPS have anything to do with this. I doubt it, but I am just guessing

Put a normal MAF back in there. didnt it run before the injector/maf upgrade and ECU retune?

Do you have a tuner shop near you? I say take it to a dyno and have her run. Check all readings on the s-afc and try your damndest to figure it out.

I am a big fan of enjuku (Ken rocks) but it is possible that they made a goof on your ecu. Hence the ecu not reading or adjusting fuel propperly and your having your problem. I have no clue what they do at enjuku as far as retunes go (didn't even know they offered the service) But get a good idea on what they do and see if it can be undone then send your ecu to JWT

If Ken is reading this "Sorry d00d":(

Your issue has to be something simple. Since this is a new post and none of us want to reference back to the old post(lazy Baztards) Didnt your car run right before you added everything and what all did you add? How long have you had your afc? There are a few settings you need to have set up on your afc or it will do this. I dont think its the maf. You can start the car up without that so its something else. Could be the injectors but does it flood out and fowl the plugs. When you do get it started with the help of fluid does it run rich and what does the afc say. If anything take the injectors out and put the stock ones back in and use the stock ecu and get it somewhere so someone can help you. If you can get it to a shop and let them look at it I bet they would figure it out in less than 30 minutos. This is frustrating to me and its not even my car but I feel bad when someones redhead is down.

Ok I decided not to be a lazy azz and I went back and read up on it again. Im gonna lean more toward the ecu but check your maf wires at the maf and at the ecu. Did you just install the afc. If so there could be something wired incorrectly. What does your afc say when idling or trying to drive it? Such as Air %, injector duty cycle, etc? If you want you can disconnect the afc which just requires unplugging and making sure the maf wire is plugged back into the ecu.

Ive decided to pull the whole wiring harness and have it checked by a professional......to see what is not hooked up properly....

Im going to start with a clean slate with this car......I havent been confident with the wiring job since Project D hacked it in....

This way I will start with a perfect wiring harness so there are no questions on that front.
