How can you tell its bank 1?

Ok, I was thinking injectors also, so I installed 8 new gm injectors for 5.3 truck engine #12613411. No change. Would fuel delivery issue show up on the o2 reading? I'm going to try new plugs. ...

ok thanks, will do. I did some wot blasts tonight and definitely heard pinging.145444

Ok thanks, I ordered knock sensors. I've noticed there's a misfire that sometimes coincides with knock event. I banged around on stuff but didn't notice anything unusual. Oddly, 93 octane seems to...

Ok thanks, Yes I'm getting knock at wot also.

Ok thanks, So I am correct in assuming that real knock is not possible at zero advance on a stock setup?

thanks, I'll replace them. DO you have a log of what a typical gen4 should look like?

Has anyone seen KR at zero degrees of advance? Not sure how this is even possible. I swapped out the LC9 for an L96, everything is stock. I've spent over a year on this thing and can't rid of the...

I submitted the logs that hp tuners requested, but got no response. The truck runs pretty decent now. I've went back to almost stock timing table for now. I smoothed the high octane table and...

thanks ls rob, I haven't messed with timing that much yet. Another thing that makes the timing spikes less aggressive I noticed, is having the vve absolutely smooth. Also When I would smooth the...

When I use your formula and leave the maf enabled, the bucking hasn't returned. The formula gets me very close to commanded vs actual afr. I'm not sure what I am missing but, my commanded afr is...

Alvin.. Ok thanks. When the maf is reenabled does it stop happening? Once is more than enough for my liking. But you?re right it doesn?t happen often.

GHuggins. Ok thank you. I couldn?t find any info on this issue. So which tables will I be changing when using your formula? The truck came with 5.3 not the 6.0, I didn?t think it would be this...

here's a clip of a spike where engine torque is 1300 ft lbs at 1200 rpm and timing drops to zero.

its definitely not torque management. There is no shift occurring, the accelerator pedal is not moved, the converter is not applying. Every time it happens, there is a spike either up or down with...

For some reason every time I touch the stock vve table to tune my new cam, I get wild advance and retard spikes randomly while cruising. The vve table is smooth. The delivered engine torque spikes...
