Thread: OBD2 fwd VVl+t problems !

hey guys and gals I've been having some management issues lately , first ill give you the specs of my car then maybe you guys can recommend something for me to do . SR20ve+t , garret gt30 turbo, z32 maf sensor , 608cc yellow top NISMO injectors , NGK iridium plugs , JWT ECU , NEOAFC piggy back , and walboro 255 pump .

so first thing is my car runs fine until you decide to full throttle it , for some reason if you keep it in first gear and take time to redline it runs fine but if a any time you try to open the throttle it won't even try to go through RPM , now at first i thought it was the ECU so i sent it back to Jim Wolf to get remapped . Once i got it back nothing had changed the car was still doing the same thing .right now I've stopped driving the car because now something is killing the battery and the radiator fans won't turn on ......someone please help

Heads up they are going to blast you for using a JWT product..

close the gap on your plugs to .25 try that and see if it will pull all the way to redline.

Not tryn to try your intelligence, but make sure that your maf is facing the (it has an arrow pointing) right flow direction. dont ask me how i know, it can happen to the best. Also ensure that your safc connection are properly insulated;stranger things have happened before, lastly check your main fuses under hood for obvious problems.

Get rid of those iridium plug and get standard NGK bkr7e plugs and gap them at 28. Check the spark on each plug wire and spec out the coil and ignition parts for corrects ohms. If that does not fix it sell the jwt ecu and get a nismotronic SA.

When you had the ECU remapped, did you clear the settings for the NEO AFC? There may be something lingering on there that is causing the issue. If the JWT ECU is properly tuned for your set up, unplug the AFC for now and see what happens.

As for the battery draining....well time for some eletrical diagnosing fun... good luck with that.

Onto the fans... They should not kick on untill 212*F. If the car is actually getting that hot, and they are not turning on check your relays and fusable links.

Interesting.. I've been running NGK Iridiums since I've had my VE, think I will try your suggestion and see if I notice any positive changes

They are fine NA they are just harder to adjust gap on due to the thin electrode. I have seen many broken or burnt/ melted electrodes with these plugs. Carbon build up also seems to effect them more.

your n/a right?

no your not trying my intelligence and yes its facing the right way
