I am new to using the ecm link and tuning. i am looking for some advice on my log. the car runs like crude from 4500 rpm up unless the car is cold it seems to run better. i believe i am running lean in the 4500 rpm range and on up. please help me tune my toy

your o2 voltage is flucuating up towards 5k. whats your wide band look like at the time it starts running crappy? you arent pulling any timming so it isnt knocking.

i am hooking up the wideband tomorrow. so i will know more then. what would cause the o2 to flucuate?
and am i missing any step for my tune?? i think my MAFRAW is off but i dont know.....

your o2 volts will change as our afr changes, the only problem is that the stock narrowband o2 is kinda useless if you afr isnt at 14.7. and by mafraw you airflow our what?

I mean my MAFRaw seems off compared to other logs. i know everything varies car to car but this just seems way off. i could be wrong.

i disconnected my meth injection and that was the reasone it was running crappy. my wide band shows 9:4-9:8 pretty lean?

When i installed my Gm mas i had to move when my alcohol was being injected and i think it is to close to the throattle body and not getting adimized well enough. here is a 3rd gear log. Please critique it for me. the car seems to not have much power once im up to boost. I think its from running lean and knocking????

Thanks

I went and added 7% more fuel from 3,000-7,000 Rpm But i still read lean.(9:4-9:8) and get about 4.6Degrees of knock starting at 3,985 Rpm...???

had a brain fart.. i guess i would be running WAY rich at 9:4 ratio.. sorry about that hehe
