mods in sig

i am pulling 17% from 2K to 4.5K in the Airflow map @ 100%
Boost is hitting 18 psi and finishing at 20 psi at redline.

a/f is in the 9s from 3K till 5K were it leans out gradually to 11.1-11.5

my fuel pressure is 41psi vac line off 34-35 vac line on

Car feels like ass till 5K when it leans out. Pulls hard right near redline.

I have clamped as low as 4.10, but the a/f is still in the 9s.
I have upped the clamp to 4.64 from 5K to 6.5K.

PLEASE HELP

[Ant]

here is a the e01 screen
boost is in bold
10.2 reading is the A/F, the e01 will not read any lower, my lm-1 reads 9s





my ad injection map is 0 everywhere

what else should i do to lean out the midrange?

[Ant]

any suggesttions?
lower fuel pressure more?
help

Maybe try fooling around with your map clamp a little bit.

Sounds like a boost leak problem is the start here . . .

The increase in boost pressure towards redline would be a cause for your A/F to go up. Boost should be spiking then falling towards redline. This will allow you to start at a lean condition and drop to rich. Mine hits 12.0 then falls to 11.8 towards redline.

ok, i was trying to use the rpm offset but not working because i have not hooked up the brown wire from the e01 to the tach driver. gonna do that to get consistent boost.
I have lowered the pressure more and now it is in the mid 10s when boost comes on and i added fuel after 5K in the aif flow map to keep it from going lean. and 9s at redline, will update with more info as i keep tuning it.

Sorry I really can't help you too much with tuning the E01, but I can help you with boost and A/F.

Keep updating though . . .
