Adjusting HIGH/LOW RPM timing

[WildHorse]

On the T2 is that a global setting ? Thanks.

the WOT spark adjustments let you increase or decrease the commanded timing for the given RPM range.
For your Nitrous adventure, you could use it to command less timing at WOT after 4K when you'd have the window switch set for example.

Thanks.
So we finally got some Shell 93 octane ... I can use this parameter to add timing to WOT then ?
Currently got 91 tune, how much can I add ? Add to both the below and above 4k ?

yes, that will work. we usually find 93 can take 1-2° over the 91 settings.

Some random over at Mustang6g , engineer mike I think his name is, that doing a global adjustment is the worst possible way to adjust timing. Something about a whole lot of other parameters have to be adjusted as well. So, it kinda got me worried so never bothered to try it. So question is, is he correct ? Or does your software make all necessary adjustments ? Cause all my knock sensors are doing is adding timing, not taking away with 93 octane on your 91 tune.

On a side note, I got all kinds of PB's this year using your custom 91 tune. No nitrous. All motor.
60' / 660' / 1320' ET & MPH by a large margin.

the issues could come in under part throttle since the global adders add everywhere, all the time.
Using the WOT spark parameters will only add in the WOT ranges, which will avoid any part throttle issues.

Good to hear on the PBs!
I hate seeing everyone chase custom tunes when they're all getting the same basic canned tunes.

My 20 GT went 11.78 @ 119.5 with our tune as the only change. I was plenty impressed, and don't see many tune only cars running better.

A10, right ? My 17 GT ran the exact same ET but @ 117 mph with a 1.6 60'.
This was with the MT82 & 305/45R17 MT ET Street R Drag Radial .

Yes, A10.
I actually did it on the stock Michelin PS4S tires
1.78 60'. I rolled in s l o w.

Went back the next week and went 10.98 @ 129 in my buddies stock/tuned hellcat with the same tires in 275 width

Gotta love fly paper tracks.

Try it with a manual trans, IRS, and drag radials on a basically no prep track.
Then you can brag hahaha.
