Good morning
On way to work I got 2 CEL codes.
1 P0219 ??
2 p0159 o2 slow response?
What would cause p0219?
Thank you

Did you disable the secondary oxygen sensors? Shouldn't be a P0159 with the secondary sensors disabled unless Ktuner is not great on the J series. If you have them disabled you might contact Ktuner support. Might have a bug in your specific application.

P0219, did your tune adjust the rev limits? Could be the transmission control side that is causing that code. The automatics don't like increased rev limits.

 

Hi
yes I just disabled p0159
Yes I raised rev limit 7600.

 

Sounds like you quickly found two bugs with Ktuner software. I would reach out to their support team and see what they say.

I don't think you will be getting around the over speed error. As far as I know no one tunes the transmission side.

 

Will do .
another thing I'm confused is the drive by wire table.
In help section of ktuner it say 83% is 100%. Of TP opening.

 

DBW table is for changing how the throttle plate responds to the throttle pedal. Stock is not a 1 to 1 relationship and really it is probably best stock.

You could set it 1 to 1 like a throttle cable but they don't drive as nice. There are some other things you can do to improve drive ability or feel.

I haven't looked at Ktuner, They might be saying that requesting 83% or greater is the same as requesting 100%. Or they might be saying that 100% is going to be reported by the throttle position sensor as 83%. That would be more typical.

 

I just did a data log. And my tps at wide open reads 114%. .
I changed it back to 83% I'm trying to figure out the trims and AFR. SO IF IM IN -7 that means-7% fuel taken out. But I'm still at 14.4afr. So can make changes at higher rpm band and add 7% fuel?
