Underperforming Lund FF tune??

[stang305]

My previous car was a cobalt ss turbo and I had an e85 tune also on it. I would data log multiple times so that the turner could make the tune as best as he could. Here's an example every single car is not the same. Also where you live makes a difference hot temp area cold temp area. These tuners I'm sure make a general tune to the mods that you let them know that you have. How do they know if your tune is working properly on your vehicle for max performance if you don't data log your tune. It's that simple

Sct :doh:

Sorry, I missed that. I'm not sure to datalog one but there has to be videos.

Not sure how to log it. I can say on the factory display on 93oct it appears fairly rich with WOT A/F at 11.3 or so. On E85 it around 8.8

8.8 AFR ?! :doh:

Have you ran yours yet?

Just got the car a month ago haven't had the chance to run it. When I lived in Miami I went to palm beach raceway. Not sure how the track is near us?

8.8 AFR ?! :doh:

That seems normal in the 8 range from what I read on e85.

I know right? Seems lean for E85....

Whats ideal for idle and wot?
Idle I see 10.1-10.5 I assume the quality of e85 would affect that. And also affect the wot values if its not pure e85 right. That's the whole FF principal??

I'm putting it back on 93 today. Might even load up the non FF tune. Or through in my steeda tune and see where my AF is on that one.

Yours is an M6 right? could be driver.

Been racing my entire life.... I can shift lol. Like I said we raced just on the street.. even 4th gear pulls the stocker was right next to me. No driver error there possible.

Maybe you do have a tune issue, who knows.

 

[Sick03L]

The AFRs that you've listed have all been wayyyy off target. 8.8 AFR at wot is just unheard of and 10.X at idle is also unheard of. Either your figures are wrong or your car is running awfully.

On E85??
