i was just like you a couple of months back, lost and confused, so first off i would suggest that you get a Wide Band sensor installed just as 5FDP mentioned, and then you can start doing some magic...

okay so i did a ton of reading and from what i understand is that i have to use the formula you've posted in one of the threads which is , i am sorry if this is too much to ask but where do i add...

Yeah that has been fixed or so i think, i dialed in my VVE quite a bit so i'll take it out for a long and see how it goes, and i will look into the Rich after re-flash issue, thank you very much for...

btw other than that, car runs and drives great I've dialed in the vve good enough to let the O2s handle the rest and MAF does a good job at WOT, even fixed the shifting issue by dialing in my trans...

thank you for chiming in, i have tried doing what you've recommended for quite a bit now, nothing is really working as it still does the same thing. :/



They're from DeatschWerks and as far as...

i don't think the stutters i feel are due to it going lean but i'll give it a try.

I've been trying to fix up my MAF and VVE after my mods on my 13 ZL1 A6 and it's going great and i am learning fast as i go but i'm experiencing a few issues, this has been discussed on here before...

I'm having the same issue, and i'm pretty sure he is setting up for MAF, but either way my AFR err does not log to either MAF or VE graph set ups.

i am maxed out as the injector data provided is larger than what i can input into HPT, so do you think all the injector data is fine? as the car drives pretty well.

you see the thing is the numbers provided exceed what i can input.
i'll try what you've recommended and get back asap.

Thanks for the Help Sultan, i see you lowered timing and added a bit of protection here and there, about the fuel pump do you think i'm running out of Pump or there is a problem with my Pump? i have...

thanks for replying, and yeah i'm hooking it up to my pro link soon enough, 98 pump gas where i'm from and my actual AFR reads 10.9-11.2 so i guess i'm good there
i've added a few pids now so i will...

thank you so much for replying,
and i'm sorry i should've mentioned that i live in the UAE so we have 98 octane pump gas so i'm guessing that's why timing is high? as i haven't touched the tables...

Bump, anyone?

that's only if it worked.

I've done a few changes here and there in the tune, car (2013 ZL1) seems to idle and cruise fine and WOT seems to be decent and the car feels strong, the only issue is that it just knocks when i down...
