After seeing this ve table and some other edits I am not confident by any means. Unless powervision 3d graph is that bad compared to tts this is one of the choppiest ve tables I have seen after a dyno. Especially on the rear cylinder. Had to upload the file again. Something went wrong with first file

No not exactly, That value was just recorded at that moment, If it was also accompanied by a Knock Retard event or shortly after one, Thats what the ECM is adjusting the cell to for a short time, It decays back to the set value over a few cycles. There may also be other factors from other setings adjusting values. I had wondered why I was seeing 0's when I had none in my spark tables. There is also the closed throttle spark table, Which I enabled and set a little lower than the 25 degrees that was already pre set there but not enabled. If Knock events aren't huge or reappearing at the same Kpa/RPM consistantly I was advised to let the ECM do its job. If you want to adjust timing yourself in those cells just pull a small percentage of the amount shown and look at the cells just before and diagonally of the knock event that was recorded.(things happen so fast theres a little lag time) And possibly add a little fuel there, I don't explain things very well, So I try to stick to the basics but there's a lot of good info in this thread.

Rev limiter issue... not working?
Im not sure it something is prohibiting the PV from bumping the rev limiter or if I am not doing something right.
I have it set to 6200 and flashed... it says its set to 6200, but still falls on its face at the stock 5800 rpms....
Any ideas or insight? thanks

you'd have to review a log of your ride data to see what's going on. if your motor is stock you're not going to get a lot out of revving the motor beyond 5800. besides we're only talking a 400rpm difference- it could actually be banging the limiter at 6200 before ya know it. depends how fast you're winding it up. but anyway post a log so others can have a look.

The PV is new to me and to read 800 + pages can be daunting to say the least.. LOL!
forgive me for my lack of knowledge ( I have a lot to learn on the PV ) is there a particular 'log' I need to run?
thanks again..

It probably just feels like it's hitting the limit. i.e. Look at any number of Dyno charts and almost no matter what build they all fall off at 5500-5800. Your just running out of gear, Time to upshift. Or try it in neutral when you hit the limiter you'll know it! It sounds terrible and you won't want to do it often.

I have hit it... a few times... tach is dead on 5800... it falls on its face. My 14SGS with the FP3 would go to 6200 and do the same....
I don't ALWAYS get up there, but when I do... Im looking for 6200 ( used to it with 14SGS) and she falls off at 5800.

Thanks... I'll start getting up to speed. IT's just nerve-racking to read thru it all and try to absorb it... overwhelming at times...

Slye, I took a look at the file you posted, dyno tune1. A couple of things, I would check to see if the rear pipe has a leak. I downloaded the DJ tune, and compared it to your tune. I would tend to think the dyno guy did not spend enough time affirming the ve tables. When Doc tuned my 12 w/tts, he worked the ve tables for a considerable time. It wasn't do the ve tables once and move on. I believe that is where the real issue is. The changes to the ve tables aren't necessarily wrong, but....I would run them a couple of more times to make sure. The other thing is that I didn't see the charge dilution tables. The tts tuner had egr tables, pv has the charge dilution tables. They are on the newer maps, just wondering if they used them, or allowed them to be adjusted for the 12's. Might call DJ to ask. Anyway you look at it, the tune doesn't look finished, in my opinion.
