Well AEM has got the final details worked out for the RX-7 93-95 models according to Kirk Miller and the tech Jason. We have the new programs and will be doing a twin turbo car next.

i still dont really know what to get because the APEXI is a little cheaper and easier to tune but the AEM has more options. Couldnt i set it to stock specs and then play with it from there?

Thanks for the info dudes.

With the AEM you can change the transition points for whatever rpm you want. That is just the start of all the options you have.

ah but what are the stock specs? see the pfc has a ton of features too, one of them being it runs everything on the car like the stock ecu does, and b features dont mean a lot. if you cant figure out what they do its worthless.

I really really want to like the AEM. I have a PFC w/Datalogit and wideband 02 now which can do the job just fine and I should be able to make 500+rwhp on race gas using the PFC. With that said, I wish I had a few additional features. First, better integration between the wideband, datalogit and PFC. AEM seems to have this covered with their wideband 02 unit. Heck you can type in the target a/f ratio and the computer does the rest. With my current setup, one needs to worry about polynomials for the wideband output, grounds, all sorts of stuff. There are too many little niggles that could screw you if you aren't careful. Second, faster datalogging and the ability to add devices and log them such as EGT. Again, the AEM has them. Third, higher resolution map. 400rpm increments are fine but I have to sacrifice if I raise my rpm and boost limit and want to retain the "resolution" necessary. If I raise my limit to 8800rpm, my maps start at 1000rpm (not much of a problem as I idle at about 1100rpm). Similarly with boost, to get the resolution in the higher boost region, I have to sacrifice resolution in the lower regions. I should also be able to integrate a 3 bar map sensor w/o spending $350 on Apexi's boost kit or figuring out how to set up a GM 3 bar map sensor and hacking a bunch of wires. Again, the AEM seems to have this covered.



From what I hear about the AEM, it's mostly the sequential, stock cars that have the issues, esp. with idle, and low speed driveability. ANY half-assed ECU can run a car at WOT and run it well with a good tuner providing the ECU's maps. I would think (and I want to test the theory out) that a single turbo car w/o cold startup, emissions devices and all of the damn solenoids missing would have an easier time getting the car up and running. Plenty of tuners still screw up PFC's and low speed driveability. I just modified the settings on a car which came back from Pettit. They had modified my settings a bit and taken out fuel globally (through PIM) which you should never really do. In five minutes I reconfigured throttle tip-in/acceleration enrichment, idle split, idle quality, etc...and he was a happy camper again. I will say that the enthusiast (people like me!) have had access to the PFC for what, three years now, so we're ahead of the game vs. the AEM peeps. But Justin Nenni (old friend from dare I say the Probe GT days!) seems to be getting some good numbers out of the AEM with good driveability too. If they're upgrading the software, there may be some issues caused by that alone which cannot be tuned out with "correct" settings. But it's a powerful unit. Let's hope AEM can get it right. I'm hoping to experiment with one in the not too distant future.

Finally someone in here that has a clue. We think the AEM is going to be a replacement for the TEC3 if all goes well Well I forgot who was even asking about this unit but don't always go with the popular vote. Try something new and innovative it can be very rewarding in the end. Alot of these homo net guys just go with what they here from NON-Reliable sources. Trust me I see it all day long .

Well, I don't know who in this thread that was targeted at but I'm going to assume it was either me or Vosco. I've had my car for 6 years. I tried the PMC & it couldn't control boost & exaggerated my 3K RPM stumble. Then the Power FC hit the market. I was one of the first to buy it. No stumble, I installed in in the work parking lot on my lunch break, & it ran much better then it ever did the with factory ECU. My choices at the time where PMC, Haltech, WOLF, or Power FC. Since the PFC was direct fit & controlled MOP I decided to give it a shot.



I've gone through many different stages of tune with that same PFC & never had any problems. I'd love to be able to log fuel pressure & EGT, but I'm not going to give up the gauges that the Commander provides as well as the cash it would take just to try something new. The fact that I witnessed a Supra lose an engine with an AEM doesn't push me any harder...



I'm not a shop, & I'm not going to impress anybody by proving any engine managment system over another.



I think the main thing Vosco was trying to say was: Go with whatever EMS your tuner is comfortable with!

you guys definetly know what you are talking about and have first hand experience. ill take your advice because you have done it before. i dont think that dude was talking about you or vosko.



thanks guys

I say PFC with datalogit you can do a lot. More than i have found a need for.
