rt .11560' 2.262330 6.1191/8 9.147mph 82.781000 11.7401/4 13.897mph 105.46

my setup is a stock internals dohc ka swapped into a 90 hatch, XTD "stage 4" clutch, full interior, T3 chinacharger, dw 440cc injectors, z32 mafs, 9 psi, emance tune open diff. etc...

And my wot afrs were like 10.1-10.3 on my eugo which i NEED to get fine tuned, because i'm honestly very upset about that.

That was my first run of the night and my only good one. My other 2 runs i was having issues with my mafs wiring rubbing on my waterpump pulley and causing me to obviously go nowhere once it ate through the wiring. I don't know much about drag racing this was my second time at the strip and the first time i ran a 15.1 and had no traction in first and part of second, but i feel i could have done a bit better.

I was pretty happy but i feel i could have done better and next time i go i'll be running more boost *around 12* and hopefully will have gotten it fine tuned and dyno'd at a shop, because this rom tune honestly isn't cutting it._________________

Good time for a very rich tune. get an afr X rpm graph and send it back for a fine tune, one of the guy from nico have rich tune w/emance also. that afr is robbing a lot of power from you. when i dyno my car looong time ago i had 10's for afr and after i got it fixed i gained a good 40whp. you should also check to make sure your oil dont have fuel in it or it will be deadly to your motor. change the oil.

Yep, afrs that rich are a surefire way to get gas in your oil and destroy everything in your motor that likes oil. I know from experience..

Dont boost much until you get that fixed. Grab a SAFC and lean it out, or try to get jason to fix his ish.

yeah i kind of gave up on jason honestly. I emailed him concerning my afrs a few weeks ago and he responded once and then i replied back twice and haven't heard from him at all since i asked what he could do for me about a retune because it was obviously way too rich. So i can't say i'm too happy with that at all..

I have an safc but i don't know how to use it and i don't want to mess anything up... I've been trying to find someone nearby who knows how to use one or find a GOOD tutorial online on how to use it, and what everything means.

try dropping 5% fuel in the areas you are rich(IE boost), if its not enough slowly reduce fuel till its in the 12~11.5 zone(towards the 11.5 IF you are worried about the tunes safety).

IF his tunes are relying on richness to be safe, that isnt a good tune IMHO, rich washes oil from cylinders and thins it to the point it no longer lubes... FAIL

I shouldnt talk **** atm, I have a rich tune on my n/a setup, but have the turbo waiting to go back on
