Wow, necrothread alert : )

If you're looking for an OFT tune suitable for ACE, look at WayneRoms.com - that would be the way to go.

I've got Wayne's tune, but I think it needs some tweaks for my case.
The only difference between Wayne's tune for standard EL header and his ACE tune is that the VVT Intake table has uniformly about 4' less from 2800 to 6000. The VVT Exhaust and all other tables are identical between ACE and non-ACE EL tunes. So almost no difference, at least not what I would expect.
I assume this is because he has ACE 250 which has shorter runners than mine which is the equivalent of ACE CS400 with the longest runners.
This is why I am looking someone who's got for VVT tables for ACE 350 or CS400

36 of maximum intake advance I usually use for forced induction lol
just use El table from left, it s already good and then adjust afr and then maximize ignition timing advance and you will have the ace gains

Don't forget that for ACE, Wayne recommends running one level of timing above your chosen fuel type, 'Please flash one timing level above normal. E.g. flash 100 RON file for 98 RON fuel'.

You may have done this already, but if not, it's worth mentioning.

Thank you, I tried the tune for 93/102 octane it and it knocks pretty bad (6 degrees FLKC). with 100 it is only about 3 degrees. The AFR also looks a bit wild and does not change much with adjusting MAF. Not in the parts with the large dips and peaks.

With default MAF:

after adjusting WOT MAF:
https://datazap.me/u/thornad/m2-3?lo...11&zoom=30-138

So I'm thinking it must be VVT.

How closely are you following the dialling in process on Wayne's page?
If you're knocking, you may need to flash a richer map.

There are moments during your WOT pull that look a bit lean.
As you may know, aside from the default map, Wayne provides maps from lean -4%, through to rich +4% on his site.

Have you tried reaching out to Wayno?
He's usually pretty responsive on email.
