You dont want to read them both combined.

Info is in the pre tune write up.

Nah wideband isnt needed.

Burning a chip is simple its all detailed in the getting started write up step by step.

Yeah that split second of richness on decel after you closed the throttle is from too much decel fuel. I reduced it quite a bit should be much improved.

Yeah something is definitely going on at that 4500 area. Looks almost like the ignition is breaking down. How old are the plugs? Have you tried running them wider than 40 maybe around 60 or so? Are you running the vb921 coils?

The fueling seems to be jumping back and forth up top.
imaf err
775 2
750 0
725 .92
700 .96
650 8
600 5
550 11
525 16

There's a bit of turbulence in the maf right around that 525 imaf range thats causing fuel to fluctutate a touch and again up top. Heres the maf curve to give you a visual.

In any case, load this in and shoot me back another.

yep its all the same

id recommend tossing a set of heads on it. any aftermarket head is a 100hp gain

yeah computer is not a concern

Your fueling went rich for some odd reason. This should have her corrected. Give this a go and LMK if its still there. I don't see any reason for it everything looks good.

LMK if she seems to make more power, less power or about the same as WOT as well with this.

The block probably got whacked. I wouldn't waste the time or effort. Unless the rod broke at the cap, oil pressure should be unaffected.

I used to score 94+ roller blocks complete from my local u pull it yard for $500. That's probably your best bet.

make sure the amplitude is .45 and the hego delay is all 20s

did you mean 2 wot pulls in the one log or did you mean to attach a 2nd log too?

the hesitation around 4500 is that at wot or while your at part throttle?

added a wot kamrf min clip yesterday. Verified it works great.

Excellent. She looks great and the new code works perfectly.

This should have her more stable on tip in.

yes

no

forscan polls generic obd2 data so the ecu is looking up what its asking for and giving it.
