Hey. I have been thinking of getting a reprogrammed ECU from MD race. Ive been trying to contact them for over a month, email and by phone, and they are not responding. It clains like 20 HP gain, and the same for torque I think, with an extra 5mpg. Has anyone gotten one of these, and is it worth it. What was the price. And also are there any other suggestions for ecu's? I really dont wanna spend that much, and want just a plug in replacement. I know superchips.com has one for like $500, has anyone gotten this one? Any tips or comments welcome, please.

Rx_treme

yeah i had one of those for like 6 months, it was great. it improved my 1/4 mile time by .4 second(on average) and 0-60 by .1 second (average) i was impressed, never clocked MPG. the car in general ran alot better b/c the timing i think.
the low end was quite a bit better, and the upper end was a bit better, and the mid area was awesome, like from 3k to 5800 rpm or so. i actually sold mine, but havent heard back from the guy yet sooo.,

Well on that note, does anyone have an ECU , mdrace or other, for a 86 N/A, for sale?

Did you have to run 92-93 octane gas in it? CJ

I heard that those things are tuned based on what altitude you're at.

I just received my reprogrammed ECU from them yesterday.
The only way to get ahold of them is to call them.
They are still making them.
I will be selling mine (For 88 TII) in a few months. Going Haltech.

Mykl

Do you have the number handy? I'd like to call them up and see how this thing works.

Awesome, thanks.

All the MD Race chip is, is a Superchips one. Just a little insight.

RXTASY1

No.... It might have been that way, but now you can get only one version of the chip.

Wrong! When I got mine yesterday, I opened it up and looked at it. It's a home grown chip. It was stamped MD Racing. They do however call it The Super Performance Chip. Maybe that is where you got that?

Here.... check this link out.

How much did it cost? Were the gains worth it?

I'd gladly pay a couple hundred bucks for 20 extra horsepower and increased gas mileage.

RXTASY1

I haven't used it yet because my engine is blown , but I have used a G-Force before it blew and did notice an improvement.
I paid $350 for the upgrade + $25 shipping.

All the MD Race chip is, is a Superchips one. Just a little insight.

Wrong!

Actually, drewstrbo2 is right. The only difference is that the Superchips includes a bleeder hose (kinda like a cheappy boost controller) that allows that turbo to run upto 11 psi. The MD chip has the same firmware (damn, the firmware checksum is even the same for the two companies for the default configuration) as the Supchips. The MD chip does not include the bleeder hose, and hence a little cheaper ($90). As for the stamping difference, you can stamp anything onto a ROM. All you have to do is bake it in UV light to clear it, then program it. Once that is done, you can stamp anything on the EPROM. Also, if you check the webpage of Superchips and MD. Damn, they are word for word the same. If the two chips are different, I would think Superchips would have a cow because MD copied their webpage (yes, Superchips came first and then MD came later...in offering chips for the turbo RX7's that is). I am only speaking from the 89-91 Turbo II ECU's. I have tried them both and also G-Force. They are all basically the same.

Yo Rxmfn,
You can also try G-Force. Here is a link: http://www.gforceengineering.com. Contrary to popular belief, they are alive and very healthy. They recently change their homepage address. Seriously though, I would recommend that you save you money if you have a 86 n/a. It's not worth it. I don't think the 86-88 ECU can adjust the timing (only on the 89-91 ECU), even w/ ECU upgrade. They will only alter the fuel curve. Ask yourself this: is it worth $400 to change your fuel curve? If you say yes, then try the S-AFC (but, don't recommend it either unless you plan to do lots of other things to your car).

Jay

RXTASY1

You have it backwards. On the 86-88 ECU, you can't adjust the fuel curve, but you can adjust the timing.

Boosting_FC

RXTASY1, Thanks for clarifying. Jay

Rx_treme

Actually if you call and talk to him like me and Rx_tasy did you'll find that they used to be their own company and they still are but SuperChips bought them out some years ago. so yes they are owned by superchips. and yes they are their own company.

They dont base them on altitude, but they can change it if you are at a really high altitude.

I thought it was worth every penny.

One question, is this only for turbocharged cars?

MaxRX7

no idea.

RXTASY1

From what I gathered, MD Racing doesn't exist anymore. It's now MD Tracking?
He told me, he has an engineer there that still does the chips.
Maybe what happened is when Superchips bought them, they changed the EPROM to match MD Racings EPROM.
This makes me wonder now?????? Did I get ripped off?

RXTASY1

No.... It's for both NA and TII's

ryanj

Do you have to use bigger secondary injectors and fuel
pump to compensate for the higher boost levels? Will the factory
stuff handle it. It sounds like a good investment for us
RX owners that seem to have a problem with breaking motors.

Thanks,
Ryan

I had one in my '90 Convertible. As said already, it was worth every penny I paid. Most torque was available at 3K rpms and after 5500, it really takes off.

You will have to run on premium gas.
