Opinions on log. (HPT)
So I did a quick log today to get started, and after making several trips working out bugs I got a short log with a WOT pull. I'd like to get some peoples opinions on it. Getting lots of knock up top, but I'm guessing its from my crappy 98 knock sensors. Mods are as follows, 98 Trans Am M6 with 1-7/8 lt's, ory, magnaflow cat back, ls6 intake, lid, 9" with 3.89 gears, and just installed BR7EF plugs in prep for a 150 shot. Thoughts?

It's lean when you enter WOT, richen it to 12.4 AFR (set power enrich EQ ratio to 1.18)
Lower all power enrich enablers to a point where it will react faster, like RPM 100 and MAP to 10.
I think you are having burst knock and not real knock. Is this with 91 octane?
Disable all burst knock and log again.
It appears you are running out of injector, are they stock?
Don't try the shot yet, too risky with you current tune.
Post your tune file too

This is the tune that was in the car. The only thing I've done so far is adjust the speedo for gears, turn of the rear 02's, AIR, and EGR MIL's. Thanks for your input guys.

Monte the injectors certainly do look max'd. I would say it isn't burst knock as it's logging under knock retard and not burst knock. I feel as though your timing map is veeeryyy sporty. I would be more sensitive to timing values especially at peak torque. You should take a closer look at your afr error to get your VE in check.
On a side note what is going to control your timing with your 150 shot?

Was planning on doing the IAT resistor thing. As soon as the rain stops im going to start fresh with the stft's and get that as good as I can. Then I will start looking into the spark. Funny thing is I thought the car was all stock except the bolt ons I had done, but comparing my current tune to the stock 98 in the repository, its much different.

Also, can you guys explain how to filter a histogram? I know you use a code, but I have no idea how to figure that out. I want to filter out when im decelerating from wot pulls.

Thanks. I got some good news today. A friend of a friend just opened a shop with a dyno that is going to let me tune my car on it for next to nothing so he can get a good look at HPT. I'm still going to work on it street tuning over the next few days to make sure I understand everything before I go.
