$350 and all these good testimonials eh? So there are no real quality problems or quirkyness issues while running these things?
I may have to get one then. If I keep the convertible it's gonna get a lot of work starting next February, a bit more power would be a good thing.
I want the car to look mint, and run even better. I just don't have the time or money to do it right now, gotsta wait until I get back from Saudi.
Does anybody actually have any figures for peak specific horsepower gains?

The estimate was from a guy named John Zentnor, after he tuned & drove my car. For those of you who can remember, John was the guy who built Brooks Weisblatt's engine, so I'd say his opinion was somewhat credible.
From a comparison point of view, I could pull away from a stock '90 GXL. That means I had at least enough hp to counter the ~375 lbs of extra weight I was toting around.
If you go to their web site www.mdrace.com, they have 2 dyno charts which appear to be adjusted for reflect flywheel hp. The way my car drove, I'd say they're accurate.

I e-mailed SAS racing and here what i said.
Ok, i have a n/a 1990 Rx-7. It has a Racing Beat exuast system, replaced stock air box with cone style K&N. Removed double throttle, and coolant flow to the throttle body. Ported black elbo before throttle body. New mildly ported 13B built by Pineapple Racing and some P.R. 6 port sleeves.
On the rx7 forum, there are quite a few people talking about ecu upgrades for the non turbo cars. (Several of wich recommend you guys.) So here are a couple questions for you. What type of power increase would i be looking at with an upgraded ecu? What type of fuel would i have to use? Would any of the drivability be lost?
I would appreciate any info you would like to offer, as i've been looking around for an upgraded ecu.
Thanks, CJ Brault
The response. (It happend within 8hrs.)
We no longer offer the computer upgrade, however we are working on a package for our engine customers that will add 45 HP to a non ported engine. Please call us at 954-784-4166 for more information. Thank you for looking us up.

Called SAS...
They're doing a package for people that they're selling engines to. They're upgrading the injectors, ignition, etc. The engines are non ported, but the water jackets are modified.. They don't have a set price yet, but they're thinkin' it will be a couple grand. The guy at SAS said it was gonna be a friggin' road rocket. He stressed that the engines will be "bone stock." Got any more questions, PM me.

Timing & Fuel ?
I was just looking at the G-Force sight, and for 87-88 TII there chip adjusts:
Fuel Map
Ignition Timing map
Boost limiter
and for the 89-91 TII
Fuel Map
Ignition Timing map
Boost limiter
Boost Control
a couple questions before I call them up, a couple people have said that only the timing or fuel could be changed on the 87-88 ECU, and how does the ECU control the boost, or limit it?

g-force is gone. it says on there website posted above. the reason it says 87-88 instead of 86-88 is there is no turbo in 86.
the 89-91 can control (well, raise...) boost because it has an electric boost controller that is controlled by the ecu. that is why it runs 8psi not 5.5. the wastegate spring is 5.5 in booth.
"jet" also makes chips. don't know anything about them. I think I'll get a chip in the spring/ summer time. I hate my FCD. I really don't think it would be worth it on a N/A car though...

have you cracked a super chips one to compare?? otherwise you are just stating that there is more of a difference between a stock one and the sas one then the chip.... maybe superchips makes the other changes too??

OH and for all you wanting to buy these:
The MD Racing computer they have for a turbo setup is excellent, but then again, an independent system is better, like Wolf 3D. However, for the N/A both the superchips and MD Racing computers don't work very well... they don't come close to claimed increases. However, both computer increase fuel economy because they lean out the A/F mixture.

hmm, right off the mdrace page
"MD Racing is also an authorized dealer for Superchips; which has the widest product line of chips in the world. MD Racing Enterprises can offer you the same wide selection of chips at a very competitive price. The following list is a brief description of what you can expect from one of our performance chip upgrades."
I don't see any prices on the md page though.

do u have ability/images to make copy of any chip for 87-88 Turbo setup ? i need image and some how-to...i have EEPROM burner and other stuff so i think that i could put it together...
i`m not about making some bussines from it, i just need it for my and friends TII's here in CZ and i can`t go thru hassle of sending my ECU overseas and wait for it till it gets back (if so) even if i would have money for it...
thanks

The modifications they make are different -- more specifically, Superchips only replaces the main EPROM that holds the A/F mixture/timing information. MD Racing modifies and sockets a secondary EPROM, as well as "overclocks" the whole computer.

edit: never mind you answered that a few posts back... I thought you were saying the SAS ones were better.

hey wait I was right, up ahead you said you cracked the sas one and said it was way better then the superchips one, but then started talking about the MD one being better...
which one did you have/open after the super chips one??

is it any different the going through superchips?? I have a superchips dealer in town so it would probably be cheaper...
or are they different chips?
