Those ecu are pretty straight forward to tune. With your setup your gonna want to spend a lot of time dialing in your volumetric efficiency, I havent tuned one of those in so long I dont remember what the files look like. I will say I was put in my place pretty hard yesterday by more experinced guys, so just take anything that Veefour and murfie say and apply it. Theyve tuned a bunch of cars and most likely know what they're talking about. secondly, always always post the tune as well if youre wanting help with it.

By VE he means the failed load table for transient fueling. Its still a mass air setup.

They are simple to dial in shouldnt have any problems.

Check out decipha page efidynotuning.com he has a lot of really good info about tuning the ecu your car has. It?s a lot of reading but he took his time to right it up when he didn?t have to. Definitely take advantage of it.

yeah ive done some datalogging but everytime i try to scan it freezes up on me this is the only vcm scanner sample of the start up of the car till i drove to work is there anyway anyone can tell me whats going on ive seen that the car is lean under 2400RPMs & after 3K it bucks like a wild horse so im trying to see how i can safely add fuel ive read a bit saying that all factory tunes are already rich but considering the car has stage 3 cams i need to add fuel safely but im still trying to figure that out on the editor.bullitt moring dive.hpl

Are you using an mpvi-2 or an mpvi1 also what update are you. Also if you?re using an mpvi2 don?t use the blue tooth to log sometimes it likes to freeze. Maybe private message decipha and get a base tune they?re $100 I believe and it will give you a strong starting point

ive looked at the editor for the 99-04 on hp tuners & it says i am able to disable the PATS system is that true & or can it be the reason why iam geting the car going into anti-theft mode while i have the scanner running but it wont do that for any other car ?
