ECMlink Fuel trim p0170

[Velmin hu]

Greetings I got eclipse gst 1996 with p0170 it has dsmlink straight pipe bigger 550cc injectors, twin Supra fuel pump, 16g Evo big turbo, a/f wide band ,turbo timer, blowoff valve, but I’m get code for fuel trim on bank 1 malfunction.

I got reading off of mine long term and short term along with o2 reading here is what I got.


I’m having around 17% reading which means lean condition if I’m not correct it at idle when I give throttle it reading goes to normal range at cruising. But my voltage is low on bank 1 sensor 2 not sure where it goes or located? Could it be that having issue since I have downpipe

If it has DSMLink (ECMLink), then post a log for us to examine. You probably need to tweak the Combined and Short term fuel trims. You would do that with Global and Deadtime settings in Link.
