968 ECU Chips?

[944-3.0L]

Does anyone know of or have a chip installed in thier 968. If so whats the best chip I can get without breakin the bank to bad?

Check out the RSBarn Chip...

[rdhayward]

I have a ProMax and like it very much. I know some are averse to the whole Flash/Pete consortium, but I have little doubt that Pete means it when he says he's tested the rest, and that his is the best. I know a couple guys who race 968's and they both have RS Barn chips and like them very much.

Hmmm well has anyone dynoed their car to see the performance gains

944-3.0L You don't have to poste a new tread ,just keep adding ??? to your existing one this way everything is gone to be in the same bundle.

I have Promax was in when I bougth the car no problem with it ,like it.

Well my other thread is about my car. This one is about 968 chips.

LOL _ Promax & RSBarn chips are like two old horses witch I've been kick in the rear so many times that it's hard to say witch one will get up first & pull ,there has been debate about them both here & on rennlist so many time it come to a point where you don't know who to believe,What I found out is that chip or not you don't want to exceed the red line specified by Porsche on the 968 I know I won't witch is I believe is 6,500rpm.Personnely I think that you shouln't even bother with a chip given the weight of your 944 & the power available (power240bhp@6200rpm) (torque225lb/ft@4100rpm)

Well I will admit that it is really quick the last time I had it weighed it was like 2647 pounds. The only reason why I'm lookin for chips is because I just want that extra oommff

Maybe a chip will make a hp or two or less than another. What Promax has done is make throttle response and driveability much better in addition to adding HP. They've proven this with hundreds and hundreds of satisfied clients worldwide.

it's amazing how much attention this particular topic gets - i am constantly stunned by how prolific it is

re redline: 5 years of shifting at 7k plus and no signs of issue yet (kids don't try this at home) - stock redline is 6700

re: throttle response, drivability et all, nobody has the corner on the market on that, and every one of the chips from every major manufacturer improve all of that to much the same degree - they do it via different means, some with more timing that others, and some focusing on fuel more than timing, and they all vary in quantifiable results - there are plenty of independent dyno charts out there now comparing the chips though, and while they vary on numbers, they all show the same clear winner - most people choose not to post them so as to avoid the inevitable bashing by those aren't happy with the facts

there have been plenty of chip threads and "discussions" though, and the real information is not hard to find, even after sifting through all the hype and nonsense

[Damian in NJ]

I've yet to see a dyno chart that can quantify throttle response or driveability. So if I give up one or two hp that I can't feel anyway, and gain better throttle response and driveability, I'm fine.

But to 944 3.0L, go with your gut. And getting a custom chip burned will always outperform and generic chip, no matter the maker.

[flash968]

those are hard features to quantify, and i have only the multiple opinions from those who have actually tried multiple chips in their own and same car, and yet all still chosen the same chip

p.s. - i have pretty much all of them here, from each of the manufacturers, and am more than happy to let anyone try each and every one for themselves - contact me to pop by and see for yourself - i have the g-tech and dynolicious to verify things too

i'll run whatever does the best, regardless of who makes it - i've changed 3 times, each time gaining performance and drivability, and each time in conjunction with a set of mods - i now have a custom chip, and am just about to get another

[traxxas25]

go with rsbarn's chip. call up pete or email him and he would be more than happy to email you his dyno charts of his chips. i would say do the stage one chip and the airbox mod (assuming you used the 968 airbox in your swap) youll be VERY happy with the improvements.

[944-3.0L]

Well I did a k&n cone filter and stock headders to a 3 inch collector to a 3 inch 100 cell race cat then to a stock replacement 944 muffler. Should I still go with stage 1 or go with stage 2. Just want to know if there is a difference between the two.

[flash968]

stage 1 is for OEM exhaust

stage 2 is for the 4 to 1 header, but will not likely work well with that exhaust

From the ProMax site-and remember, they manufacture their own chips, they don't have them burned by another vendor.

The ProMAX Performance chips for the 924S, 944 & 968 normally aspirated models have been extensively developed to provide not only a power increase, but also improved smoother running.
All flat spots and anomalies have been engineered out of the original compromise chip (ECU EPROM). To ensure that emissions are not effected, changes beneath 3,000 rpm are minimal. The timing curve on these chips is substantially smoother than the original with the often pronounced step in the mid-range made more progressive.

Power gains at the top end are between 5-10%. Power increases of up to 20% have been recorded on cars fitted with a cone type air filter and free flowing exhaust.

NOTE: For 968 models, there are 4 types of chip. 2 for the USA market and 2 for ROW (Rest of World). USA: 7100A or 7700AT, ROW: 7100R or 7700RT. 7700 only advisable if your engine is in good shape or you want a higher RPM limit for track use.

How can performance be so easily improved? Why didn't Porsche build this performance into the car to begin with? There are many reasons for this. Some cars are deliberately kept in a lower state of tune so as not to get too close to the performance of other models (i.e. marketing reasons). In the case of the 968 - where a 18bhp gain is typical - this was taking it too close to the current 964 models output of 250bhp. In the case of the 944S2, the 944 Turbo was only 39bhp away and the 3.2 Carrera (at the time in 1989) was 232bhp. Other reasons included ensuring the car can use low octane fuel and survive a few missed services.

If you are prepared to use 98 octane fuel (not essential, but best to get the maximum performance) - you can enjoy the performance that your car is actually capable of. Power gains are anything from 10-25bhp (often more) with torque gains of 15-22lbft. NOTE: All power and torque gains are dependent on your car's current engine condition, modifications and induction systems. Power gains can not be guaranteed.

lol - 4th place

First, the 968 motor has 11:1 compression and you should be using 98 octane (premium) anyways. Second, I agree that they do some things for marketing reasons (like why they only made a few 968 turbos), but they also do this for reliability. Stock motors have a safety margin built in by running them a little lower than max. This is why its not uncommon to get over 200k miles on a Porsche... If you want that little extra power, a more aggressive chip will get you some by playing with a number of items (timing, fuel, etc...). Just know that if you chip the car, that small margin gets even smaller (aka you are more likely to hurt the engine). You just need to keep that in mind (not a big issue for street driving).

That is exactly why I don't recommend chips that raise the redline; after all, these motors are pretty torquey.

Ok so I took advice from everybody and bought both the rsbarn and promax chips. They should both arrive today gonna put them in and test them against each other through the seat of my pants. Oh yeah I was doin a little street race and lined up against a turbocharged 240 with 25 lb of boost and built internals. We went from a (dig) full stop to 135 and I smoked the 240 badly pulled him by 2 bus lengths wooooohoooo. Can't wait for the chips.
