What do you think? I need advice bad..
I grew tired of the smoke and fumes my car produced when first starting it up in the morning. I read the manual which came along with my PFC and I changed the following things:
1) On the Inj Map, I changed values where the car idled. It read 1.214, so I changed them to 1.250.
2) On the water temp, I changed the settings at +20C and +30 C to lower values. +20 was 1.59..now is 1.35..and the +30 was 1.29 and now is 1.21.
3) I changed the PIM percentage at 1000 RPM from 100% to 98%
End result: car doesn't smoke as bad upon initial startup and the gas fumes are almost gone.
Did I do "the right kind of things"? Or are these values usually "bad" for my engine??

>>Yup, normal, leaned it out when you water temps are low
3) I changed the PIM percentage at 1000 RPM from 100% to 98%
>>Leaned it out a couple points @ idle
End result: car doesn't smoke as bad upon initial startup and the gas fumes are almost gone.

Reason I changed the value from 1.214 to 1.250 is because of the air fuel ratio. From what I understand, the map was based on a 14.7 to 1 ratio.
In the manual, they illustrated changing the ratio from 14.7 to 12 to 1, which is leaner..correct? If so...then 14.7/12.0=1.225 which is a larger number than 1.214 even though the mix is leaner. Is this correct?
If the above is correct..then I changed the ratio from 14.7 to 11.8 at idle: 14.7/11.8=1.25 which should be leaner.

Related note....You really need an accurate A/F reading not the theoretical for Inj Map changes. Then at that point you can change your fuel correction map value by calculating your desired A/F into what the Actual shows on a wideband A/F gauge.
