Today, I received my ProMAX performance chip in the mail. I have a 1988 944S, euro spec. I'd like to start off by saying that delivery was extremely fast. I ordered this chip two Fridays ago, and it left last Monday. This chip basically went from the UK, to New York, and over to Germany since I'm on an Army base. 8 days and it was here. Every question I had, which I e-mailed directly to Andrew, was answered promptly within a matter of hours, sometimes immediately. Customer service was excellent.

Installing the chip was simple. Just a matter of pulling the ECU out, popping it open, and swapping chips. The only thing I'd like to note here, is that in the instructions, where it's telling you out to pull the top board of the ECU out, it has a note that S2's have an additional clip on the front side for the ECU harness that holds that top board in place. It's the same for the 944S as well.

After installing it, I hooked it back up to the harness and started the car. Immediately I noticed that the idle was about 100rpm's higher and much smoother. With the stock chip in there, the idle would fluxuate a little bit. Merely pulling out of the parking lot, I felt the power band was a bit lower as well. There was definately more torque in the lower RPM's. I have 10" wide wheels in the rear, with Dunlop SP 9000's (275/35) on them. Before, just starting out in first I was only able to get the tires to chirp for a second or so. With the ProMAX chip in there, I had 21 inches of rubber spinning freely in the rear almost halfway through second before it finally caught traction.

The pickup while accelerating was noticeably more as well. When falling back and accelerating to pass a truck, I realized as I was passing him that I really didn't need to fall back as much as I used to in order to get up to 120kmh while passing. As I passed him, I looked down and noticed I was already up at 150kmh and had to slow down a bit.

Throttle response is much more apparent, and cruising is very smooth. Sometimes with the stock chip, while pressing the clutch in the RPM's would drop to about 300 or 400rpm's and every once in a while completely die.. I don't know what exactly was the cause for that, but I haven't had any problems with that since I put the ProMAX chip in earlier.

Overall, I'm thoroughly impressed with this chip. With its affordable price, I couldn't be happier. I haven't put it on a dyno yet, so I don't know what the exact horsepower increase is. Hopefully within the next couple of weeks I'll get a chance to dyno it and see where it stands currently. This chip is an easy horsepower boost without having to touch the engine. These are the kind of modifications that I like, where I don't have to modify the engine at all, and still get power boosts. It took me maybe 20 minutes to take the ECU out, pop it open, remove the chip, install the new one, and place the ECU back in the car.

Overall, I drove for about an hour and a half after installing it, and did not notice any difference in fuel consumption. When I fill it up again, I'll be checking the fuel consumption, but from what I've seen today I doubt there's a significant difference.

I highly recommend this chip for a simple way to gain achieve many great improvements ontop of horsepower. Thank you Andrew for all your help with ensuring this chip would work in my euro spec 944S.

With regards,
Rory

Is this test posted somewhere that we can read it?

Im also very interesting in the chip. but I have 2 questions:
1. could it pose any problems with the electrical system? (I just spent 500$ to get the last gremlins out...)
2. what would the whp gain be on a 89' 944 n/a?
Thanks
-Sebastian

I would also be very interested about any gains for an 89 N/A.

I won't ever buy anything again without true dyno runs of before and after. PERIOD

Hi Sebastian,

A chip is purely data - it's like putting a CD into your computer. The data on the ProMAX Performance chip is modified to improve the performance of the car . This data is used by the ECU to instruct the injectors when to pulse and the ignition to fire. It is completely harmless and will not compromise your electrical systems in any way. A little like upgrading from Windows 98 to Windows XP! (sorry, that's the best computer analaogy I could think of).

Power gains on the normally aspirated 8v models are only moderate (8-10bhp on the 2.5, slightly more on the 2.7) - but this is only part of the story. You will notice smoother running and better torque spread. You will also feel better and more instant throttle response. We don't just make changes to the wide open throttle maps - all the fuel and ignition maps are modified to deliver a better and more responsive driving experience! A cheap and simple upgrade that you can genuinely feel (money back if you don't).

Andrew

Hi All,

I'll dig out the links to the aricles in both Excellence and Nine Magazine. Both were for the 968 chip. I have the links at home buried amongst all my email responses.

Hi Rory,

Thanks for the feedback. That was a quick delivery (considering how it must have reached you).

As you have discovered, the improvements are more than just peak HP.

All the best.

Regards,
Andrew

Hi

I have a question too ,

Does the fact of putting a powerchip into a car could be dangerous for the engine ?
which modifications is necessary it to bring so that the engine turns without any risk ? I think a bigger fuelpomp (3bars)

Thanks
Soory for my bad english

ps: i have a 944 S2

Which issue of excellence? I have all the back issues.

Testimonials just not doin' it for you?

M758

I'll believe it when I see it on back to back dyno runs. Till then I figure 2-3 hp max.

I don't know about the 944s but the beauty of Andrew's chip (and other chips) on the 968 is not just peak power but overall drivability of the car is greatly improved. There are a lot very happy 968 customers out there and there is an article floating around from Nine magazine with some chip results for the 968.

While I don't run a Promax chip, it was tops on my to do list for awhile before I went in another direction. Andrew's customer service with the 968 crowd has been very good and he has satisfied a lot of owners.

I don't think anyone is saying anything bad about the chip, just that they want to see documentation before shelling out money. We support all rennlist sponsors!

I already have an aftermarket chip... does it do anything? <shrugs> I dunno, it was put in the the PO so I can't tell any difference in "overall driveability" or using my butt dyno.

If I ever get a chance to run it on a real dyno (and if I put in the 91 or 93 octane the chip needs), then maybe I'll put up something about what a great (no longer available) chip this is. In the meantime, I don't brag about my NA's power or race the 951s...
