stage 2 fuelit just installed, VRSF downpipes/intercooler with v6.1 stage 2+ MHD 93 OCT tune.

Could anyone tell me if the timing corrections during wot here are bad?

It is so confusing, some platforms -KR is more timing and some platforms -KR is pulling timing.

Thanks!

I see a few of those hits that are showing 2-3 degrees on an individual cylinder.. seems to be favoring 1,2,4 for timing corrections.. and some throttle closures as well. Were these runs made with traction control all the way off? if not you should log with traction off in a gear that doesn't spin to ensure the throttle closures arent related to tire spin. You could add a little octane in it to get rid of those timing corrections. pulls would be better to judge from a 2k rpm pull to redline or at least 6500rpm and shift into the next gear for a few seconds before letting off.. a lot of rpm range up top there is no data for. even though you may always short shift, sometimes it is useful for seeing the bigger picture.

Yes log is too long and cluttered to review. Now that MHD has auto log the procedure should be easy. Floor it at 2000rpm in 3rd gear with traction control off and keep it floored until after you shift at redline for logging purposes (or whenever it shifts if its the girly trans) then let off the gas and save. Save NO cruising, no part throttle, no 800rpm etc. Just one clean wide open throttle 3rd gear pull. Repeat to see if things are consistent. For intercooler logging same procedure except extend the (single WOT) run as long as you can without going to jail (deep into 4th gear still WOT although that can get you in jail lol).

That log looks really strong. Those OTS flashes from MHD are either getting really good or you got lucky, either way there's nothing to worry about there.

It's not like it's hard to just drag a line over the parts that the accel pedal is at 100%, DataZap has a really great UI. Logs are for more than just WOT runs, you can tell a lot more with all the peripheral data when it comes to trouble-shooting things.

That's understood when you are logging for yourself and understand what you are looking at. When you want forum members to review your log you want to keep it simple and short. I just opened it and refused to un-zoom all that. I know that's kind of f*cked up but I'm sure many others do the same thing.

Boost -vs- target seems to be off by >1PSI in many areas. I don't know if the 6.x maps have more aggressive targets, but on my 5.x map, I'm typically <1PSI from target.
