Gen 7 help
Kinda a weird questions
There are a few things that I have had all year
code 23 tps voltage it is there every time I start the car ? I have talked to another guy with an LT1 and Gen 7 and has had the same thing?
Is there anything that might pop into your head on what to look into?
2nd...
the car all year has had a miss???? but the miss is intermittent...
you drive the car and it feels like for that one sec something is Turing off it is a real dead spot, it will do it under light load under 3000rpm or if you are trying to pass someone on the highway under 1/2 throthal, I don't think it is doing it at WOT...it didn't show anything on the dyno......
what should the WB02 line look like when driving around town......mine is spikeing up then down..not very smooth at all....should it be straight and what should I set the read time at..
thanks

THe WB will fluctuate some, but for the most part it should be pretty steady. You might have some 13.X - 15.X ranges, but nothing line 10.X to 17.X stuff. There are times when the car will self EGR and fresh air will be going through the exhaust, so it will seldom be exact on anything. Now under a constant load, or cruise, it should hold fairly stable.
The code your getting needs to be resolved before continuing, if you have a miss this will come through as a lean spike, and might be causing what your seeing on the WB.
Get that resolved then see where you are at.
I can probably look at your logs if you send them to me and can assist you in any tuning you might have. I do them for guys on here for their OEM systems, and have been doing the DFI now.
Shoot me an Email and we can discuss...
