So plugged the new ECU in, pulled the fuel pump fuse (so as not to have pressure, didnt want to start it at this point), installed the noid light, and cranked it over. I have injector pulse! Plugged the fuse back in, I have fuel pressure! So i unplugged the ECU, opened it up, installed the type 3 bo...

New ECU arrived today. Plugged it in and turned the key on, I get fuel pressure! Thats a step up! I will have to borrow the noid light again and pull the fuel pump fuse and check to see if I am getting injector pulse tomorrow before I install the Nistune board into the ECU. But its definitely a step...

Thanks for the reply, Matt. I just double checked and i AM getting RPM signal in Consult while cranking. I used a noid light on the injector to see it wasnt receiving signal, but i guess i should try at the output from the ECU, like between pins 101 and 107? I guess the question i have at this point...

Hey guys, ive been running Nistune for a while now on my CA18DET, never even so much as a hiccup. Love it! So ive now got a 1993 KA24DE that ive turbo'ed and put into my 1990 coupe and i am having a problem getting it started. The body wiring harness has never changed from the car through the 4 diff...

I found it odd that it didnt come off as a dead miss, but rather as bogging down, limited rev, no boost. It was weird that all my Consult gauges looked NORMAL...

Yeah, coolant temp seems to be accurate. What is FTemp? That one seems to be spiked to max as soon as i start the car. That might be my problem. And yes, i can communicate with the ECU the entire time. Ive data logged the even, but nothing seems abnormal other than it wont get over 2000RPMs. On anot...

ECU goes to fail-safe mode, but only once engine is fully warmed? Ok, im having a problem. Not sure when it started, but i believe it was before installing NIStune. I havent been able to drive the car normally for nearly 2 months now. Anyway, start the car from a dead cold (like sitting overnight or...

Car is a 1990 Nissan 240sx, originally KA24E, swapped to CA18DET with socketed ECU and ROM tunes. Has been running for over a year and a half. Just got the NISTune type 1 board. I installed it and got it running for about 30 minutes total. I was having a lot of intermittent connection problems. The ...
