i just got my s5 t-ii running new warranty rebuild with the ap power fc. had a couple questions. i hope some of these issues are partially due to the low compression of the new engine > 100 miles.

#1 throttle response is not sharp sluggish for example when blippiing to downshift i have to really gas it. I assume this can be corrected through the commander under acceleration enrichment. i have know idea how to adjust the injector lag and decay times. also when i press the acclerator quickly the car goes lean for a second, 15.5-16.1 on the wideband, so im real slow with the throttle right now

#2 when im coming to a stop, if i push the clutch in from say anywhere > 1500 rpm and let the revs go down it dies instead of idling. if i tap the gas right at 1000rpm as the tach drops it will idle.

#3 is there a way to set up the pfc to cut the injectors when you crank the car at w.o.t.

hybrid turbo, 3in exhaust, screen over turbo inlet, 550/1200 inj. cosmo pump, stock fpr, stock i/c, street port, plx wideband, ap power fc.

 

also, in the sensor check menu on the commander i have "***" and 4.98 volts in the "slot" that is normally used for the fuel temp voltage which my car does not have. this information is highlighted in the commander to suggest a malfunction but i get no exhaust temp light, could this be causing problems? also my check engine light does not come on at anytime now. is that normal?

 

Check all your intercooler piping and stuff. Make sure you don't have any vacuum or boost leaks

 

i wish it were that easy

A1: Assuming that you have a DATALOGIT: Settings 2, INJ vs TPS1, bottom row,
increase right column to apply more of the fuel listed in the Accelerate Injector (ms) table.

#2 when im coming to a stop, if i push the clutch in from say anywhere > 1500 rpm and let the revs go down it dies instead of idling. if i tap the gas right at 1000rpm as the tach drops it will idle.
A2: adjust the dashpot to slow down the throttle closure rate. Settings 1, increase the F/C fuel cute value (rpm) up higher. I use 1500 rpm.


#3 is there a way to set up the pfc to cut the injectors when you crank the car at w.o.t.
A3: The PFC does it if your TPS voltages are set up correctly.

Even though you have a FC, I sell a set of PFC tuning notes which might help you even though they are FD orientated.

 

thanks for good advice unfortunately i don't have a laptop or datalogit so im out of luck. it doesn't matter know anyway, i have to take the new engine back due to faulty seals/oil burning
