Hey,
the Eforce 1580 has not enough power - my feeling.
I correct the horrable settings from SCT, but it wont wake up.
Throttle is full open by 62% relative TPS.
I have corrected the LWFM Table and the Maf Airflow.
It runs stock at 5PSI .
Is this really all ?
My previous N/A Setup had only 360 HP and was close to the Eforce.
With 2500 Stall and 3.73 I expected much more Power....no wheelspin in 2nd.
Can anyone take a look at this?

ETC Max Throttle Angle vs. RPM----- set all to 82 degrees
LTFT Learning Max TPS----- set at 40%
Fuel Base vs. RPM vs. TPS-----Set fuel lambda to .80-.81 you have it commanding too lean
Spark Load Increase Correction vs. RPM vs. Load---- lower table to pull less timing for IAT I usually dont pull any till 130 degrees
ETC Pedal Position WOT Start----set to 300
ETC Pedal Position WOT En---set to 500
You need to log more items like fuel commanded. Youll want to check it all with a wideband as well.
Thanks.
corrected / check your points.
I think its the low PSI. Other users say with 3.50 pulley theyve got real 460—480 HP at Engine.
Set Fuel to 14,6 and 11,7 at Wot, corrects transient.
Do WB when 3.50 pulley is installed. AFR shows 11,7 this time at 0.84 lambda.
thanks for the response...
after changing pulley I m going to a new setup.
I take care of your tipps.
I just want to calibrate the maf failure load table - by logging it is much lower than the stock eforce file.
first I calibrate the Maf, then log the load table and take the max values - is this right?
At last I use WB to set Fuel Base Table....
the base fuel table is a set and forget table. You do not use the fuel table for anything other than setting the commanded fuel you want.
To dial in the failed load table first you need to make a WOT pull. Plug in those load values at the top of the table.
then set up a histogram to plot load across tprel and rpm same as the failed load table. After you've driven around to get some what ballpark data plug that in to your tabl- it doesn't have to be perfect.
Then set the backflow region switch and set the backflow minimum tps to 0 and the maximum to 1023
Disable long term fuel trims and set up a histogram to plot fuel error with rpm on the x axis and tprel on y axis same as the failed load table. Then wait for her to get in to closed loop and try to hold each cell as stable as you can until the fuel corrects. After you've gotten enough good data apply those corrections to the table and then repeat until you have minimal fuel errors.
If you still have the SCT give me a shout and I can help you out significantly. There's absolutely no reason why you can't spin the tires on a supercharged 3v unless you have some slicks or stout drags etc..
seems like my fuel pressure drops to 165 kpa.
will work on that, rise voltage to 13.5 - if this doesn't work, a new FP will be the answer.
maybe the rising of pressure will help at tip in at closed loop.
I got time and will find the answers.
I had an issue with my fuel pumps that caused me to replace them as well, that helped drivability. I found that increasing the upper limit on the torque inverse table to 535 and modifying the spreadsheet to recalculate helped a bunch. At that point I just used the stock values and recalculated both tables and my fuel has been right since.
