well the Visual part of the test went fine, welp minus the p28 ECU i was running (couldnt find my friend to get my p72,damn't)

Comprehensive Visual Inspection: TAMPERED (ecu)
Functional Check: PASS
Emissions Test: GROSS POLLUTER :\

now i failed the emission test on high HC and CO numbers, take a look...

Idle Emission Results

HC #'s

Max- 100
GP-250
MEAS 443

CO #'s

MAX- 1.00
GP- 2.50
MEAS- 1.26 (idle-1036rpm & 1.78 MEAS 2500rpm-2588rpm)

[MEAS = amount measured] --- [GP = Gross polluter limits] --- [MAX = maximum allowable emissions]

now what could cause these high HC and CO emissions? can anyone analyze for me? i guess its time for a diagnosis, any smog station will help me correct?

Thanks In advance ppl.

Get a stock p72 and change your cat if it is the original cat.

obviously the p72 needs to go in, now my question is, can a chipped ECU, ALONE create those high HO-CO numbers?

the cat was changed recently, everything is ready to go....

thx ppl

Kamin

depends on how the ecu is chipped
if its running a stock closed loop-type program it should pass fine.

We tried to smog a D16Z6 once with a chipped ecu and it did not pass. We just went out and bought a stock P28 and came back the next week with no other changes and it passed with flying colors.
