13.2 is what I tuned for while tuning WOT N/A. Recognised as best A/F as far as I know.

alright thanks man. another question did you touch the degrees while tuning the a/f. cause when did my first log i was running consistant 11.5 from 2500-7900 and from 8000-8500 it was running 13.1-13.4 which is good. so i just adjusted the a/f from 2500-7900 about -8% but the a/f didnt move. should i adjust the degrees to?

You have to adjust the fuel for the right degree it's running at or alternatively a crude way is to make sure you have ticked the adjust all angles box before changes.
If you post your .kal and datalog I'll take a look.

this is actually the base map, for some reason i think the map i tuned got currupt and doesnt want to open so ill just start from scratch and i never had any counts of knock before this run and now its at 1.

What car do you have mate? I'v had a quick look and your 1 count of knock was before that datalog so was maybe on your part throttle.
Your also running really rich.
I'll take a look now and send you something back.

OK, I have done some quick changes.
I have a few questions for you though.
1. Your VTEC is very low 3k. Did you set it that low?
2. Your idle was 750. I moved it to 850 that ok?
3. I switched on flash MIL if knock detected for your peace of mind, that ok?
4. Is that the base cam angles your using or did you change them as they are very conservative.

Try this and do another run for me.

Just realised your VTEC crossover didn't engage at 3k like your parameters have it at but at 4.5k.
Also you can ignore the questions on cam angles, cross over and idle as looked at the base map in kmanager for reference.

Just took fuel out on your various cam angles and raised your idle by 100 and enabled the flash MIL light if knock detected.
Nothing else.

OK try this mate.
Done a few fuel tweaks.
I've changed your VTEC a little just to try something out. I'll put it back if you don't like it. I've raised the limits slightly and change the pressures.

i think vtec at 3000 is a little to low for me maybe around 4000-4500 would be good. unless thats a good spot?
