When I talked to Superchips, '89 TII, they were very nice. If you have any mods, which I do, they send a form to fill out, requesting info on upgrades and boost level. They then make a chip to corespond with the equipment. No CARB certification on these chips.There is a $125 additional charge for this.
I believe chip for stock @ $550, with mods $675.
With stock TII they take boost to 10 lbs, and override fuel cut etc.

ill be contacting ELP motorsports soon to see the prices on their chips, the other thread about EL Prototypes is a different company.

ELP claims, 16hp on n/a 89-91s, and 50hp on 86-91 T2's, let me get prices this week, hopefully i can do it soon.

i'm running a panspeed light sport tuned ecu on my TII. all i can say its AWESOME. only 7psi right now but car is VERY fast. i was hitting 13-15 psi on the old engine and i never detonated ! tuned ecu's will make a huge difference on a turbo car

Does anyone know if this chip is any good or are they all about the same?

why are you guys kncking on the reprogrammed?
in the series 4 ECU there isn't a chip that you just pull out. it is soldered into the board. this type of set up defers the load to other dedicated purose chips for prossesing. it basicly just directs trafic and tells the other chips what to do.
on the style where the chip is centralized and easyer to change, it does more of the prossesing itself. so it does it faster and can resend new data at a higher rate. depending on new data it just received.
And what makes the power in our cars???
It perfect mix of timing, air, and fuel.
Mazda set the computer up for driving on the street on a variety of raods and conditions. They also did this on the suspension. Too many variable of conditions and drivers to get the perfect car.
So if you make the computer have a better combination of the important stuff and how it is used, then you have closer to the perfect car for you and your conditions.
They ask you how your car is set up, ie mods.
Also Mazda built this car for performance anyway. There are reliabilty issues bacuase of this. Like the Transmissions for instance. The car operats too close the the limits of the transmission. they helped this in the series 5 and nearly fixed in the series 6.
Also the stock fuel management is not the best design.
That is why a mod chip for a V10 could have better gains. those are set up for pulling at low RPM from the factory. Change the important stuff and the power curve could change drasticly.
The RX7 ECU is desinged to operate a higher RPM limit alot due to the motor design.
Now I'mm not saying that they make the Dyno room near perfect conditions for the car. They may, but that doesn't mean that the rechips don't work. No one is saing that they work as good as a new performance ECU setup. We are just saying they do work. Stop knocking them until you try them.

I have an 88 TII and last summer I purchased an ugraded ECU from www.authority.com. $395

Here is what they say:
The company currently offers performance chips for four Mazda models. One adds 12 horsepower and 14 ft-lbs of torque to the 1986-88 RX-7; another adds 36 horsepower to the 1987-88 RX-7 Turbo; another adds 25 horsepower to the 1993-95 RX-7 Turbo and the fourth adds 11 horsepower and 13 ft-lbs of torque to the 1992-94 MX-6 V6. Customers send the ECU to Autothority for these conversions.

The car definitely felt much stronger after the chip installation. I have only slight mods(RB catback, Bonez intake and custom cold air) Also 30 day money back guarantee. The chip is gold socketed in so you can put the stock chip back in yourself if needed.

That is common, a lot of the time you have to de-solder them from the board and then solder in a socket.....

I was thinking the samething...when you get a chip for the ECU you have to give a list of mods that you have on your car. If you didn't have the chip made for YOUR mods then the performance might not be near the level of the other car that you got it from. Remember that timing and all that is very touchy so what works for one car with X mods MIGHT NOT WORK for car with Y mods. Good deal though, I would buy a chip...but I'd rather have a Haltech and a wideband O2 sensor. Glad to hear it worked out for you though.

Sonic

Overpriced and the claims seem a... uhhh, BS? Stuff like that would tell me NEVER to buy from them. If it were that easy to get power everyong would do it. I also know MX-6's well and I know you can't near that power with ECU upgrades with them either.

Blah... I don't buy it for a second.

My E.L. Prototypes EPROM should be here this week. I don't know what all is done to it off the top of my head, but the fuel cut was my biggest concern. And when I upgrade more in the future... re-burns are also affordable from them. He knows the computer (done it a number of times), does not claim any rediculious numbers, and those retail for $269 I believe....

You don't have much faith in engine management do you...if only you knew how important it really is. Those gains aren't near outlandish if you think about it...actually they could be on the conservative side since they're just the average and not an instance type of boast. Just something that nearly all engines will gain, if it's tailored to a specific engine you can gain much more. Tuning the engine at each rpm range (0 all the way up) is very different from overall timing or even the S-AFC way of adjusting at certain rpm spots. What works for a most part doesn't work for a whole...that's what haltechs are for so why not a chip???

sonic... re-read my earlier post.
