My car is a 94 Auto and I only want to make anywhere from 50 to 100 more horspower but I want the car to remain as or more reliable than stock. Assuming I an PFS PMC is properly tuned would it be a good buy? I'd get a used one so I wouldn't be paying the 1000 dollars or so new ones cost. I just want some opinions. Also does the pmc controlle boost. Everyone says it controlles boost maps and I'm sort of new so I don't know what that exactly means.

Try this test:

Call the phone number to PFS, and ask them these very questions. You will then see what kind of support you will get if you buy one.

I've already heard that pretty much no support is to be had be pfs, but (again I'm new) what kind of support would I need if I have a straight forward installation and a person who can tune it for me? Also I have and auto so that reduces my options. Thanks for the warning about support from pfs though.

Evil Aviator

How can anybody possibly answer that question?

yetisoldier

You seem to keep forgetting that I'm new at this and wouldn't know if you could answer it or not. Hence why I asked. I have know idea what kind of support is needed for any kind of aftermarket computers besides what it comes with.

OK, my question to you:

I want to remodel my house. I found some plans for a house on the internet, but there is no support. The plans are much cheaper than new plans that have support. I am new at this. What kind of support is needed for remodeling a house besides what comes with the plans?

yetisoldier

I suppose I'm starting to get your point. Then answer this question what better for the money (400-500) for and auto?

Unfortunately, I have no experience with the 3Gen RX-7 or auto transmissions. However, I can list some products for you to check out. Your best bet would be to ask the 3Gen forum what works best with your car. Here are some ideas:

I love the PMC and highly recomend it, to R1 users.

You see, every RX7 seems to react differently. The guy I bought it from couldn't see WOT in his touring with the computer, and I believe it was a '94 FD. Do a search and you will see others having weird problems. Similar to the oddity of some FD's having AC problems with a PowerFC, and others don't.

I have an R1 and the comp. is great. Just plug it in, and it is set for 10lbs, 12lbs and 15lbs. Yes, fuel and timing maps are already in it for intake,smic and catback. So, the worst you could do to your car is safely boost 14lbs and run rich.

And no, the PMC does not control boost. You will need another boost controler. The comp is piggy back so it only effects timing and fuel and boost for all the different RPM ranges. But what else do you really need to control?



So anyway, I LLLLOOOOVVVVEEE mine.

Good Luck.

thanks for the info. One question though. It is doesn't control boost how does it affect the boost for all the different rmp ranges? You also said it is set up for 10 12 and 15 pounds of boost so does that mean a need a boost controller also to take advantage of that? Thanks

The controler has a screen to set boost and fuel cut for over boosting, that is what I meant. I believe it may try to open the WG at the setting, not sure, but if you have a turbo back large exhaust the stock WG is ineffective.


You don't need a BC to 'take advantage' of the stock maps. If you have a cat-back only, chances are that you will naturally be limited to 15lbs, so you can WOT it in setting 3 (15lbs) all day safely. You see, the stock cat will provide the neccesary restriction to keep you in a safe range.

As far as support, you can contact EMI computers and they will help you I believe. I have never had too. This thing is so damn easy. Like I said before, it is preprogrammed for intake,catback and smic, so just adjust the default setting according to your mods, or lack thereof.

That would be considered boost control. If I remember correctly it has a setting for the primary and secondary turbo.

Who is EMI Computers? If you mean EFI Systems, they will not support the PFS PMC.

I take it you don't like it evil? Thats the vibe I'm getting.

I don't like anything that is technically advanced but lacks user support. Most of the "gurus" on this forum also share this point of view, and most of them will tell you that user support is the most important issue when choosing an ECU. It has nothing to do with the product itself, as I have never tried it.

You know how sometimes the military buys some really cool, expensive, whiz-bang gadget, but they don't bother to show anybody how to use it, and it ends up sitting on the shelf or it gets turned back into the supply system because the commander doesn't want to deal with it? Well, that's where I think you are going with the PFS PMC unless you have some way to get user support for this thing.

Didn't read the link, but I have heard rumors that EFI (knew it started with E) doesn't deal with the thing and refers you to PFS and visa-versa.

But, this thing is so uncomplex, I don't see why I would need support, unless the whole thing dies and starts displaying error codes. He has been selling this thing since '99 and nothing 'catastrophic' like that has happned to anyone, I don't think.

So tech support, yes, on a full replacement ecu. But this thing, I paid $250 for and make 14psi runs all day with it with no more tuning on my part other then taking it out the box and putting under my carpet.


I'll cross the tech support bridge when I get to it.

Try to PM "huffner" with your questions. He is the PFS contact who has a presence on this board.

He was quite helpful in answering my questions, but then again he was selling me the $125 Pink 9 firmware upgrade ;-)

And no, EFI will not support it any longer.

EFI has a web group on yahoo groups, and very often
'Doug' who designed it, will answer a question now and
then.
I've been using the PMS for about 3 yrs.
I like it.
I have a 99' purple and it DOES control boost.
Mine did a good job of controlling boost until I opened
the exhaust etc. but even an aftermarket controller
couldn't solve that problem unless I de-mod the car.
