New to these forums but i will be here for the long run. i have a red top sr20det in my 240sx that i just recently put in (two weeks ago). i was about to run some codes on my ecu when i noticed the led on it was lit. i cranked the car over and let it run for quiet some time and noticed the led was still lit, so i gave it some gas and held it at about 2k rpm for thirty seconds still the led stayed lit then the same at 3k rpm. does the lit led mean the ecu is shot? it said on one of the posts (when i was searching) that it means its time for a new one. mainly just looking for some more imput so i just dont buy an ecu for no reason. i have suspicion that it might be the ecu because my car is running strange its guzzleing gas like somewere around 100 miles to a TANK! i have a walbro and a aeromotive fpr. the car sputters at full boost 7psi in low gears but high gears its fine sometimes third and on. in first gear at about 4 grand it makes a brrrap! sound and a giant black smoke cloud engulfs ne1 behind me. i hooked up a wideband o2 sensor to it and its super lean under full throttle. pulled the plugs today and there was alot of carbon on them cleaned them checked the gap all good. hooked up a timing light 15 on the dot its a mystery to me and others. sorry for the long post i just want my car running good so i can enjoy it.
