All models of the 86-88 RX-7's run with 87 octane fuel with the stock ECU, so I don't see why you would want to spend $1,000 to $4,000 on an aftermarket ECU. What exactly are you trying to accomplish?

I guess Iwasnt clear in my question. I meant that an increase in octane gas needed isnt an issue because I have access to race gas. some peopel buy aftermarket ECUs and arent happy in the need for higher octane gas... I want the ECU to improve the fuel and timing maps to be less for economy and leisure and more towards a road race car. They dont cost $4K either... thanks for your help

a few places have them for around $300 or so. Jet is one. can't remember the others. someone else can post a link for ya.
keep in mind everything you do has to be within your class limits. check your rulebook before you start doing stuff.

Yeah I've already run this modification through my region for use in PE class and they okayed it on the exception that a tech seee specs or talk to the company supplying it beforehand. This was most likely a kind gesture given the fact that ill be running 88 motor and my car is a pile compaired to some of the feild in PE. i'm just gathering information for now.thank you though.

Here is the most common aftermarket ECU for racing on race fuel, like you were mentioning. I'm sure that it doesn't cost anywhere near $4K, hehehe.

Here is a list of PROM update manufacturers:
G-Force: http://www.gforceengineering.com/. But I just visited their webpage, and they are out of business, officially.
Powerchip: http://www.powerchip.com.au/. They are located in Australia but they have dealers here in the US.
MD Racing (same as Superchips): can't seem to find the MD webpage now, but try www.superchips.com. Same thing.
Authority: if you can find it.
Jet: http://www.jetchip.com/.
I don't think anyone of them has a firmware for race gas. I think they only program for premium pump gas, but you can ask them if they are willing to customize.

the use of race gas doesnt matter to me. i just wanted to point out that octane needed doesnt matter, whatever it takes. I just want the best bang for my buck and wanted some numbers to comapair and hopfully personal opinion. Ive never shopped for such a thing before

Ahhh, you want a chip, not a an ECU! :p
Well, I think that Boosting_FC pretty much covered the chip thing. I don't like them because I think that a Haltech E6K, Wolf 3D, or TEC II is a much better "bang for your buck". If your racing class does not allow for an ECU, then I guess you are stuck with the chips as your next best option. If your car is really that much of a "pile", then I would imagine that some of the leading drivers in your class would be willing to give you some tech tips.
I think I finally understand the octane issue now. (I'm kinda slow, so that's why I ask a lot of annoying questions). If the rules allow for racing fuel, then you should use it. Otherwise, you will get the most power from the lowest octane pump gas that doesn't cause knocking.

I have heard that for 86-88 Turbo ECU's, no chip really adds any performance, it may only slightly alter the timing and remove the FCD.
The 89-91 Turbo ECU upgrades alter fuel maps, but this is not true for 86-88 ECU's. The series 5 (89-91) gain about 20 horsepower more in chip upgrades because of this.
