it wasn't an EFI class it was an automotive school in oklahoma a vocational tech. the instructor was a moron but there were many others there that knew their stuff. The dumbass instructor's name was Ron Anderson and I didn't get my money back no. This was back in the day do you have any recomendations for any good efi101 classes in the midwest with any knowledge of rotaries? I would like to take a EFI class but I don't want to drop a few hundred dollars on another dissapointment.

Not to derail the class based derailment...
Question for everyone with the Power FC and just the keypad. I'll probably be picking up the datalogger soonish, but for now looking for a little advice to try to pass emissions.
The car will almost pass on the default maps dumped in by SR Motorsports when I bought the computer. Unfortunately I'm running 2-3 PPM too high on the hydrocarbons. Yes. 2-3 PPM. Legal limit around here is 150 PPM, and the closest non-passing test was 151 PPM.
Washington emissions put the car on a roller, and you have to accelerate and hold at a certain speed - been a while since I did the test, want to say it's 25 mph. I know it was right near 3k on the tach, close enough that I began to wonder if closed loop or open loop would be better - I could probably go just over 3k if needed, or stay under 3k and stay in the speed window requested by the test.
I'm fairly certain that if I'm running into higher HC readings, I should lean out the a/f ratio some, to drop the amount of unburned gas. Any other suggestions? (beyond the normal clean air filter, new plugs, etc)
Just looking for ideas. Probably going to be pulling the FD out of the garage for the first time in over a year soon, which will mean getting emissions done, so that I can get current tabs.

Lowering your HC, you could lean it out. But be very careful. Also you could try ethanol.

Jesus! you made it sound like you took an EFI class.. not some carb/general automobile class.

sorry didn't mean for it to look like I knew anything about EFI tuning, I do want to learn more about it. does anyone know any classes in the midwest? who can teach how to do a large amount of tuning. I've got the pwr-fc with data-logit and I do have access to a dyno from a local shop but I need the knowledge.

If you don't know much, I think EFI101.com will provide you with good start ($495).
If you want to learn more about PFC and if you have a datalogit, you should know about the datalogit message board... There are ton of info.
Also, PFC subforum on RX7club will tell you quite abit about PFC.. Also Chuck sells nice write up about PFC ($35). I would share, but its unfair to do so since he spent many many hours writing this.
But to be honest, if you are to stick with one set up or not planning to make ton of power, I recommend getting someone to tune for you (Steve Kan, BDC, Claudio, Etc). I'm wanting to do this myself because I have 2 FD, going to change turbos, engines, different ECU, etc etc.
