Just did a pre test today to see what E85 would look like to the California dyno test. Passed accross the board except the slow speed Nox. My '00 with high-flow Goodwin CAT and deleted pre-cat has been on the car for around 4 years and subjected to a failed coilpack and repeated tuning runs of between 10:1 and 12:1 AFR's so I think a new CAT will fix the 100 point difference I need to pass. It did pass the 25+ mph Nox though so I'm pretty confident that a 3 stage CAT will pass easily.

So no need to swap the old 280 injectors back in . E85 is here to stay!

Bah, e100 or nothing! Make your own and u can drink it too!

what else did you have to do to run e85?

420 cc.min main injectors from an RX8. If I were to stay out of boost these would run fine all day long by themselves. But I'm running 16psi of boost so I also have 1100 cc of injectors (2) in the intake manifold. For good measure, in the event I can't get E85, I have a MAF signal adjuster that Bill Mercer built for me that will trim the fuel down for regular gas or any mix I happen to have.

New CAT in and passed smog dyno. I had read on a couple of other forums that were linked to by Google that E85 won't pass smog. One even said "don't try it, you'll be caught!" Hahahaha. It looks just like any fairly clean running car would on the readout.

when i got my car in 08 i had to replace the cat. 2012 rolls around i'm about to have to smog it for the 3rd time. if it's bad this time around, i'd blame it on stock running pig rich. do you happen to know how rich it ran stock?

My wideband says it's stoich 14.7 +- out of boost. On boost 11.5+-.
