91 Octaine program 1.1 1.2 boost
It was done on a dynapack the wheels where removed
and the dyno bolted to the wheels

your opinions please on the state of the tunning based on the dyno results





thank you

Looks like it leans out above 5300 rpms. I think you need more fuel.

I AGRREE as well. I had the same set up but I ran a 5 bar which helped alot...
but then hes running it on 91 octane and at 1.1/2 bars ... he probably should stay under 1 bar.
I ran 100 octane on the same set up and ran 11s afrs at 1.3 bars but anything after that I needed fuel.
Boris, is that ur stage 5 set up or is it something else.

 

Wow, if your wheels could do that alone imagine what numbers you could generate if they were actually attached to the car. J/K from another former E39 M5 er.

 

Wow, way lean up top. Looks good other wise. If you add more fuel it is going to make even more HP and TQ. It is too lean and will cause some issue if you hammer it to many times.

 

As suggested it is way too lean @ 5250rpm+.

 

This car is begging for more fuel. It needs to be fed with at least 60lbs injectors.

 

where did you connect the wideband...the exhaust?

 

Who did the programming for this tune? That could tell us a lot.

 

Whats the optinal air-fuel ratio, 12.0 to 1?

This looks like Kevin's package and dynapack. This setup got more to it with fuel upgrades.

 

all he needs if hes not doing it so already is run a 5 bar like I did and my afrs dropped dramatically from low 13s to high 11s... low 12s.... I had the exact kit... and it ran awesome at 1.3 bars with 11.7 afrs....
