hay guys I'm new to zilvia . net but I own a 93 240sx and I just put a sr20det red top swap. It runs but it won't rev. over 2500rpm well thats a guess really b/c the tach doesn't work but the speedo does and so does the gass gauge. I'm kinda stuck on the whole situation and wich to get it fixed so I can run the car. I think I got the o2 and maf wired correctly I've followed heavy throttle and nissain perfor. mag. swap guides.

remember when checking maf wiring use a DMM/DVOM - an analog voltmeter will very likely ruin your ecu

also try cleaning it off with a little bit of carb cleaner too

did this happen right after your swap?

or was it normal up until now?
