Seriously, Rotaries only smell bad with the stock ECU. I have no cat on my '86 and it will idle smoothly at 14.5:1 and run elsewhere about 15.0:1 and there is no odor at all except if you floor it (then it smells like oil smoke from too much injection due to a modified OMP linkage).

My '91 has a cat and still smells bad.

Congrats on the pass Brian!

Sucks that you even have to go through all that with such an old car. We don't even need to bother testing them in Illinois, emissions exempt.

Thanks man!

What is your timing and kpa like to run so lean?

Timing is stock (5 degrees ATDC L, 20 degrees ATDC T)
It runs about 50 kPA of vacuum with the timing retarded that much.

I can't go much lean of 13:1 without retarding the timing a lot (it actually uses less fuel to idle with 10 degrees BTDC timing though, because it is running 70-75 kPA of vacuum).

I couldn't really get the idle smooth without retarding the timing, it idles like a weedwacker with normal timing numbers.

Actually, I use the pit in my timing map to stabilize the idle. The timing increases gradually below 1000 rpm and above 1500 rpm, this means that the engine gains power as the revs drop below idle (when engaging the clutch), giving a little bit of stability (improves driveability).

I wish I could idle closed loop, but I still haven't gotten that to work smoothly (probably need more timing retard).

Interesting. Thanks for that. I'm sure I'll be playing around with the idle again in the spring with the new injectors and the coils.
