Hey guys.. seems i've ive really hit a dead end here!

Attached is a link to my dyno graph..

Any help with A/F ratios would be great..

As for my mods, well...

basically

spoon engine
spoon T/B
comptech icebox
power FC/ hand controller
Spoon header,
2.5 custom exhaust

and a few other things..

Now I KNOW THE AUSTRALIAN dynos are diff to U.S. Hence lower figures

The car was tuned in 40 deg heat.

Also I think i'm at 16 TDC, 18TDC might invoke too much detonation so were keeping it at 16.

HELP!!!!!!!!

Am I reading the graph correctly? 13.8 A:F ratio at ~3,000rpm??

Do you have a fuel pressure regulator? Can PowerFC accomodate for the lean/rich condition by itself?

 

yes you are reading correctly, what should the value be???

also i have a FPR in my garage. Power FC can accomodate but only within small margins!!!

 

cmon guys help??????

 

fuel maps can only be modified with PowerXL or FC-Logit. Handheld can
only change timing and injector multiplier.
i would suggest raising fuel pressure.
Also with 11.1:1 CR i dont see why detonation would be an issue unless you
are using substandard fuel.

only change timing and injector multiplier.


Incorrect, you can change fuel injector pulse width with the commander.

 

keep them coming!!!!
