****ok this is what i folllowed for wiring. I have already tried two different mafs to make sure thats not the problem. apexi said the ins and outs should be 6 in and 7 out which is totally wrong it wont even run. after searching I found 4 in 7 out. which breaks up bad. the best i have got it to run is with 1 in and 6 out. it runs smooth up to about 5psi by that time you can tell its just not running like it should so i get out of the throttle. will a rom tune for n60 maf fix this? PLEASE ANY INFO IS APPRECIATED. THANKS

 

turn the key to ON and go into the SAFC and see what the actual mafs voltage is. It should be in the 0.5-0.8V range. That'll tell you if it's wired up right. I can tell you this... 1in 6out is NOT right.

 

so i took the n60 off and replaced it with a n62...set the in to 2 and the out to 7 and it runs perfect.....so i guess it was the n60. i just gnna get it rom tuned to z32. i need one though if anyone has one for sale...

 

There are shareware rom tuning programs out there that work quite well on ca18's. The ecu is quite easy to chip since you just pull the stock chip and solder a socket in it's place. U use a sst or 29c256 chip. Same as a Honda. I can socket your ecu and street tune it for $150 or dyno tune for $150+dyno time($150-200).
