Passed Colorado emissions again. YAY!!!!
This is a 1987, with stock AMC 360 with GM TBI with timing control.
IM240 test. On the dyno.
HC GPM: 1.5900, Limit: 3.5000
CO GPM 15.9949, Limit: 30.0000
NOx GPM: 4.0597, Limit: 5.5000
CO2 GPM: 579.4088 (Why they measure this, I don't know....)
I'm guessing the high NOx is due to no EGR.

congrats buddy! I bet you are right in that if you had an EGR (which I think you are supposed too...) the NOx would be much lower.

Congrats Ethan, another year of limo fun!
For the sake of this thread, you don't HAVE to have EFI for good E-Test numbers. These are my IM-240 results from the old 360 and stock carb.
HC: 0.2611
CO: 10.4175
CO2: 158.9269
NOx: 0.2081
BUT that was with a fresh cat and EGR. I'll bet that Ethan's numbers would beat mine under the same conditions on his TBI tune!

I got a fast pass on my last Jeep. The had a 401 and the non-EGR performer intake. I don't know why I can't hit those numbers with this one. Maybe because it was a fresh rebuild... Who knows...

The new cat makes a massive difference per my experience and the above.
