KFZE fails smog big time

Post by stang67fb »

So its time to smog the car and like the other guys with this engine I am having all sorts of little problems with it. Now that i got it running about right, (or so I thought) I take it to get it smogged and my results from just a quick sniff test are....

Idle

HC = 484 - 120 to pass

CO = 9.68% - 1% to pass

those are the mains ones there and yes I do have a cat on it

I dont really know whats going on as my klze passed with no problems on the same setup - the fact that my cat is back another foot or so because of my cutout :)

Both the klze computer and the k8 computer gave me the same super high readings....

Any suggestions

KFZE = KFZE ecu (or chipped ecu, or use an AFC)

How much are these KFZE ECUs?

To the thread maker, for one, did you do the EGR mod?
