Breaking up under partial wot to full wot

[StreetTunedTSi]

--------------------------------------------------------------------------------

OK, so the problem im having might not exactly have to do with the safc2 but, i tuned the car my self i read up on it a decent amount, car ran fine for a while, but now i cant got wot or partial wot without the car breakin up alot, the a/f ratios read between 10.5-12 @ smei to full wot, but car runs fine under cruising a/f stays between 14.6 - 15.3 and no breaking up, should i set more ne points?


my low settings
1k,0 2k,0 3k,-7 4k,-6 5k,-6 6k,-5 7k, -4

high settings
1k,0 2k,0 3k,-22 4k,-20 5k,-18 6k,-16 7k,-14

low throttle is @ 25% hight throttle is @ 75%

Correction: reads -7

karmen sensor type, 4cyl with arrow up selected

you can look at my part set up, im still on the t25 set up not 16g.

Thanks guys!!!

your af ratios look ok I dont think it has to do with the tuning aspect of it. Did you check your plugs,gap,wires,coil pack?

If your running stock inj, then your high settings are takeing away to much fuel. I'm running 580s and your settings are not to far off mine on the top end. I'm not sure how your AFRs are Reading what they are.

I think this is a double post but like I said in the other I think 12.0 afr is a little lean for gas. 10.9-11.1 is about as lean as you want to be at WOT.

is it breaking up around 2k at all? Also make sure your MAF isnt dirty try cleaning it with Mass Air Flow Sensor cleaner and see if that helps. Check the PTU plug

my guess would be the spark plug gap

Try changing spark plugs and wires.

yea i deff should ###### change out the plugs and wire, deff the coil pack 88k on my car and its deff the stock one, but i did my plugs maybe a month ago with oem ones and i gapped them a little colder than factory i went with .032 instead of factory .034 or sum linke that,pep boys wires done with plugs. not the best but they meet oem spec so i guess the wires should be fine
