Todays rolling road results

[user900]

Went to Star Performance this morning to have the fuelling checked and to raise the boost slightly. Found out that the car is overfuelling quite badly, AFR is 10:1 (0.7 volts) throughout the midrange.

Car is an Evo IV with the following mods:

Walbro 255 l/hr pump
Evo 6 cams
Evo 6 turbo (GSR)
'Straight' induction pipe
HKS Super powerflow induction kit
HKS Super Dragger exhaust
Decat pipe
APEXi AVC-R boost controller

I had 2 power runs done, the results were:

1.2 bar


1.3 bar


AFR at 1.2 bar


You can see the dip in power and torque around 5500 rpm. On the 1.3 bar run the Apexi wasn't full 'dialled in' and is still self learning.
