I am having misfires when I go WOT, I'm pretty sure it is the MAF because I'm getting an immature code saying the MAF is getting low voltage (or sending low voltage) not sure what it means, but it's code p0102

as you can see from the log attached, I wasn't able to go WOT (traction issues ) until I get up to 40mph, which exactly at this time a knock retard of 2.6 to 1.8 is applied

is the misfiring (due to the MAF) causing the knock retard? or is this something that has to due with the forced induction tune making it normal?

also, if anything else looks questionable with the scan results, let me know!

thanks!

 

You need a wideband... I'd also suggest a 2-bar MAP and tune.

From what I'm looking at, it goes lean at the same time you start getting KR. What's going on with your fuel system?

 

fuel system stays good throughout going WOT

also, how do you know it is going lean? I'm new to this, I'm guessing you are looking at the o2 B1 and B2... or are you looking at LT b1, b2 --- what values of those mean they are running lean?

also, I don't plan on tuning my truck for a while as I want to learn the software before I start screwing with my truck. I'm keeping the Nelson tune as is right now. I'm really just wondering about the knock retard

 

Looks like burst knock to me.
