With the final tunes, do all AFRs slowly drop?

 

not trying to start grief..

 

 

this was a revivsed map the day after the dyno tune I do not have a file of the original tune.

 

Look at the high end load!
Any mistakes would have been over written on the same day.
check out my original tune and leaner tune to help my turbo spool up faster on 91 octane gas.

 

regardless the cel flash for knock was turned off just checked

 

Sad to see that happen. In my experience I would definitely take the car to a differnt tuner. Hope everything goes well with your next build

 

Agreed. That high octane AFR map is a complete joke. Look how conservative he made it! 10.0 AFR on E85 is a joke. I recall that many tuners aim for 12.0 because it is ethanol. 10.0 is even more conservative than 91 octane gas which is 11.5. He is doing his best to cover his tracks but does he know you recorded him during tune?

 

maybe idk I was standing behind the car while he was in the car tuning

 

Man that sucks, I hope it works out for you in the end man.
This is the kind of thing that keeps my cautious when thinking about a mod that would require a tune afterwards

 

you can't look at AFR numbers in the map as if thats what the car is actually going to run, they are just values. I have 9's in my fuel map and thats what it takes in those load/rpm cells to get the 12.0 AFR that i want. They are not meant to be a 1:1.

 

Sorry to hear about that Mike, I've went thought the same issue 6 months ago when my engine went to hell so I know the **** you're going through right now. I finally finished my build last weekend(everything new ).

 

I'm really starting to think you don't know what you're talking about. The Fuel and timing maps look fine. Hards say for sure on timing without know what load is what hitting around peak torque, but it's fine out the top. AFR never matches what is in the fuel map, as fueling is a calculation based on whats in that map, the SD programming, Injector scaling, and MAF scaling. You could max the map out rich at 7.4, but make injector scaling 6000 and the car would still run lean.

 

This makes sense. I was wondering if these were for closed loop (which didn't make sense). Thank for explaining!

 

You're right. This is new to me. I've started logging and sending logs to my tuner to adjust for cold nights. I only load the changes and don't touch the maps since this blows engines.
