Power FC problems (sr20) Hello guys, I am new to this forum. I am just your average 21 year old dude who bought a Nissan 200sx S13 with a SR20DET and I did some modifications. I assume this is gonna be a long post, but please bear with me. So I started my car after 1.5 years and during those months I bought several parts. (Apexi Power FC Djetro, S15 turbo, 555cc nismo injectors and different things but that wont matter) Anyway, 2 days ago I started her up and it went great, except for getting the car to idle. It just WON'T idle at all. I found out that my injectors had the wrong latency. I did 66% and 0.72ms and it should've been 66% and 0.10ms? So I changed that and after a few resets and start ups it went great. First 10 minutes idle, amazing. 800-900rpm, car not shaking. Then I had to turn on the A/C which I dont have. I thought using the climate control and do some cold air would do the trick. Well I guess not. Car was doing weird things. 480rpm-900rpm over and over, here is a video; https://www.youtube.com/watch?v=GZXVeiSi1y0 I don't know what to do. My map sensor and IAT are working fine. The car was idling fine but I had to complete te self-learning process. My defroster doesn't work either because some cables are missing. (I found some cables so I am gonna try it out tomorrow, it might work) Other things that you guys might find interesting; My O2 sensor stays at 0.0v, even at idle. I found out today that there is a fat O2 sensor in the elbow, and the redtop ECU uses a Skinny O2. (I had a black top ecu, so this is why there is a fat o2 in there. Black top = fat o2 || redtop = skinny o2) Can it be because of this? How much influence does the O2 sensor have when it comes to the self-learning process? Also, the car starts with boost control on. And I don't even have a boost controller. (I turned it off) My mod list: 555cc nismo gt28 turbo Apexi Power FC D-jetro Apexi powerfilter aftermarket IC HKS wastegate Mishimoto rad AEM Wideband (haven't hooked it up yet, I don't know much about this thing. But it was necessarry for tuners?)
