Hey all

I have been trying to get my car fully tuned on speed density
i just wanna recap my car

Evo 9
stock turbo
omni4bar

I copied all the fuel/timing/map calibration maps over to the SD Rom

i got my car to idle great warm or cold start (cold start need a little help until for a few seconds)

this is the RPM VE / MAP VE Tables i have thus far

the issue im having is when im boosting 0-5lbs the car goes REAL rich right away to about 10-11 a/f

then when i boost a little more 15+ psi (just did it once i know its bad)

it gets super rich and holds at about 10 a/f
i tried both lean spool off and on...same results....

i did do logging with map/sd with evoscan

and trying to figure out further adjustments is really kicking my rear end

yes i did check the forums and ive read through the speed density threads...but its not enough info to get this to work good .

 

nothing ? I guess speed density isnt something many of you guys mess with.

 

lower the VE values for the load and rpm regions that are rich, do it a 5% at a time until close

 

I can look at your MAPVE and RPMVE and without even looking at anything else know your injector scaling is too low for the size of injector you are running. Lean your car out globally and start over on RPMVE and MAPVE.

....and your last column in the MAPVE should be 340 on the right, 430 on the left....at least to start with.

 

My injector scaling should be correct
