The reason why i was wondering if you needed to run premium, is because for my daily driver i would wrather just put in regular. I allready have a car i can only run 93 ocatane in. CJ

$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? |
Originally posted by Mykl 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. Carl Sloan SAS RACING So.....who wants to call??? |
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.

I'm really thinking about getting a chip now. Keep us posted with any additional information.
Thanks, Derek |
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? |
Yea. I looked at that G-force website and saw the 87-88 ecu , and was wondering why it didnt say 86-88? There wasnt any engine change in those years were there? Just wondering if it would work on my 86. Thanks
|
This is a great thread....I haven't seen a whole lot of info about chips for n/a's in the past....but if it really can add 20 extra HP than I gotto get one!
|
Anyone who has a aftermarket ecu.....needs to go and get the there car dyno'd! With and without a ecu upgrade of course.:)
*Bump* CJ |
G-Force
whats G-Force website url ?
btw..anyone got images for EPROM burner of any chips for FC ? ;o))) |
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... |
i need image of chip (that means i don`t want to buy chip ;p) for 87 TII

Originally posted by drewstrbo2 All the MD Race chip is, is a Superchips one. Just a little insight. |
Originally posted by 604 Your insight is wrong. It's not superchips. I'm an electrical engineer, and I cracked the thing open when I bought mine, and I know EXACTLY what modifications SAS Racing does to the computers. It's not just a chip... there's much more involved. |
Originally posted by Scott 89t2 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. |
604
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 |
Originally posted by 604 Yes. I owned the superchips before I bought the MD Racing computer. 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. hmm, by your name. are you in BC? |
Originally posted by 604 OH and for all you wanting to buy these: The MD Racing computer they have for a turbo setup is excellent, or are they different chips? 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?? |
Originally posted by Scott 89t2 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? edit: never mind you answered that a few posts back... I thought you were saying the SAS ones were better. |
