|
|
|
| To use the
charts, I set my PEvsCool to 16 in all operating temps, this takes out the
variable there. |
|
|
|
|
|
|
|
|
|
|
|
|
| Run the car on
the dyno with a wideband and examine each of the datapoints at the rpm
for the PEvsRPM table. |
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| ie. at
3600 rpm you have a value of 1.0 (wild example) and the dyno
wideband said your real world afr is 14:1, so you're running a bit lean. |
|
|
|
|
|
|
|
|
| Find 1.0 in
the leftmost column and go over to the 14.0 column, the value to use is 30,
this should give you the change needed to have a 12.5:1 AFR. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| If
running dual widebands and ou see a disparity between the two sides I
recommend looking at the average of the two banks. |
