86/87 conversion smog question

[turbobooster]

i have been wondering if any of u guys that ur states require smog test have problems passing due to this ecm conversion? has there been any upgrades that r common for our hotairs that have caused any of u to fail smog?

changing the ecm shouldnt make it fail inspection, did you change the MAF sensor too? I had to my maf was 10 with the 84 maf.

well i havent switched over just yet i have the ecm and chip from an 87 ecm just waiting to get the maf sensor wat do u mean u only got a 10 with the 84 maf?

10s to high at Idle, maybe its adding more fuel for the higher #, im new to the scan tool stuff

10 refers to grams / second of air going through

10 gm/s is too high for an idle and would probably be adding too much fuel at idle.

Warm idle with the car in gear should be around 7 gm/s.

These maf might also need to be cleaned with CRC maf cleaner. Any deposits on the sensor will effect how the sensor vibrates and in turn effect the reading.
