Honestly, some of you guys with the breathless claims and lack of information are making it somewhat difficult to cull through the BS that surrounds most chip claims. In the world of automotive aftermarket equipment in general, most of the stuff is worthless if you know what I mean.

Um, and Halle Berry is a freakin awful actress. Great lookin lady, but she can't act.

Maybe Loren does have a friend?

[DYB]

I didn't think that the reference to her had anything to to with acting !

As to references to SW 3.2 Chips, a quick search shows me a litany of recommendations by people who have used his chips. empirical evidence of HP gains is not as frequent but the common theme is that the chip leaves buyers happy simply because it makes the car more drivable and enhances the driving experience. Others could comment if there has ever been a posting complaining of a 3.2 SW chip damaging their engine.

Now as for those 2 examples of 964's with a SW chip earlier in this thread.....I would truely be impressed if a > 50 HP increase continued to be reported on stock 964's that had this addition made.

There haven't been any, despite repeated challenges to the naysayers to provide evidence.

So, are you planning on using the cheapest fuel you can find, never changing your oil, 120 degrees in the desert with the A/C on at redline all day? What's your point? You're unlikely to ever see the extreme conditions that the factory allowed for.

Do you consider personal experience to be "information"? Have you driven a Carrera with and without a Steve Woong chip back-to-back? Have you driven one for tens of thousands of miles with NO problems? I consider long-term feedback to be "information".

Agreed, but again you miss the point.

Steve

If you can post a bit on my chip that you did. If Tyson got those numbers from his C2, mine should be over 300.

BTW, for all the doubters out there, all you have to do is drive your car once you have a Wong chip, then you won't harp anymore.

I have a SteveW chip in my single plug 10.3 compression 3.2. I drive the bejeezus out of it. I use 100 octane fuel at the track and 93 on the street. Steve's chip solved a lumpy idle problem and gave me more throttle response below 4k rpms. I'm a happy customer.

If any engine was a candidate for damage due to chipping it would be mine. High compression and single plug doesn't bode well typically. 40k miles so far and it's running great.

Yeah, sure let's get overly defensive. I didn't single you out, Wavey. On the other hand, I do think people who race their SW chip on track at Willow Springs (115F ambient) to be subjecting their motors to an extreme condition. Same here, where temps get to over 110F ambient and you have to use the AC. Motor oil gets to over 120F for hours on end and you have to use a good oil and change it often. I am also running 10.5 compression. If you had asked me first, then you wouldn't assume that I was an idiot.

I agree that first hand experience is good feedback, just not the inane remarks such as "you can do no Wong". It's a cute and funny comment, just not helpful when you're evaluating a potential engine mod on your $8,000.00 engine, in which detonation, overheating, burning a valve, etc is a bad thing. Call me crazy, but I'd like a little bit of a safety margin there.

Agreed, but again you miss the point.

Oh please.

I also asked a question regarding the factory lambda setting. I was also intrigued by the statement that the SW chip "helps the engine to more efficiently turn fuel into power". Am I alone in wanting an explanation of that statement? I'd rather treat this as an honest topic, so excuse me if I want to act like a grownup.

[lateapex911]

look at the sheet poted. the a/f ratio is significantly altered.

[p911dad]

Not only does Steve W make a great product, he stands behind his earlier products as well. I had an early 2K chip he produced that somehow became related to a surging idle problem. After some testing and a little email back and forth, Steve sent me a replacement chip(4K) and instructions on doing the mod to the circuit board( a 3 on a scale of 10, basically you need a small soldering iron, a steady hand and a good eye or 2). The 4k chip works as advertised, and my old 84' Carrera is running strong and smooth again! Happy, happy.. In fact my 19 year old and I took the car to NC for the Blue Ridge Boxster Bash(huge fun, any Porsches welcome) in early June(my family took 1 Boxster, 2 Boxster S's and my car down) and the car ran through some awesome mountain roads and stayed with the best of the Boxsters, no problem! The torque and acceleration out of the curves was plenty strong for the occasion. In fact I was disappointed by the seeming lack of torque the Boxsters have as compared to the chipped 84', being able to compare them side to side for many miles of spirited running. Thanks again, Steve! Glenn

[Joeaksa]

I ran Steve's chip for 4 years before upgrading to a 3.6. Engine is still running fine with the same chip.

You cannot do any better than Steve but if you want to try, have fun!

All I can say is James' car is a torquey, wheel spinning beast. 2500 lbs, a modified 95 993 motor, close ratio tranny, custom tuned and chipped to over 300 hp, and no traction control makes for one freaky ride. I'm used to driving some 400-500 hp supercars, and this one is right up there with them. It's one of those things you have to drive to believe.

It's a fairly lengthy topic that I won't go into depth with here, but if interested, there is already a long discussion going on in the engine rebuilding forum.

Well said Steve. Which is why I tried your chip, had great results, and started this thread.

[stv951]

Hello,

anyone tried a SW chip on a Euro 3,2 ?

Was wondering if there would be significant difference there too. My car is a 231bhp non catalyst 3,2

[Steve W]

Hi - there are probably around a couple of hundred 3.2s around the world running the chips in their Euro 3.2. Most are in the U.K., Norway, Australia, Sweden, Belgium, Finland, France, Spain, Australia, and various Asian countries and don't really post on Pelican. You may wish to browse some of the post on the UK forums http://www.porscheclubgbforum.com/, or read some of the feedback by Euro customers in the reviews section: reviews. Euro customers have the Euro or 930/20 spec in their signature.

In general though, the gains from chipping a Euro 3.2 are the same as the US versions. There are also various before and after dynos done with the stock vs performance chip performed on Dyno Dynamics dynos in the UK here. The sub 4000 rpm lag is eliminated, with power coming on at 1500 rpm and pulling non stop to ~6800, much more low and mid part throttle torque and throttle response, and 15-20 hp gains in the upper rpms.

When my car gets out of the shop, stereo shop, etc, we willhave the exact same setup. I went with th Fabspeed single out so i don't have to cut anything. Are you going to Fontana in November?

4K mod instructions

Hey Steve. I'm getting ready to have my chip installed. My car is an '85 that was produced in April of 1985. Is is more likely to already have the 4k enabled setup?

[Steve W]

I think it's a 50/50 shot. In general, most of the 84s need it, many of the 85s don't, and almost all the 86s for sure don't.

[DYB]

Steve, I have observed that you burn alot of your chips with the revised club sport rev limit of (6850). Is this your default and what are your thoughts on this when combined with talk that the carrera rod bolts are a perceived weakness in the 3.2's. Should this be a concern if one was to track the car and occassionally hit the rev limit ?

[Steve W]

It's not just the Clubsports that had the 6840 rev limit, but it is a factory option listed at option M637 - 'sport group' that have this revised limiter. Their rod bolts are no different than a standard car. There are those engine builders that have the conservative opinion that the standard rev limit of 6520 is the highest limit they recommend with the stock rod bolts, and there is nothing wrong with that. My opinion is that if Porsche was comfortable producing cars with this limit, then that is also my absolute limit, unless a customer has replaced his bolts with a higher quality one such as ARPs and requests a higher limit. Every aftermarket 911 chip since the beginning has had a higher rev limit - Andial sets theirs at 6720, and there are some that set theirs at 7080, (i.e. Autothority) which I think is much too high. I don't really take a hard stance on the best limit, so I always leave it up to the customer to specify if they prefer a different limit.

The thing is with the stock chip, there really is no incentive to rev the engine past 6520. The power peaks out at 5900, and begins falling off like a rock. With a properly reprogrammed chip, the new power peak is at 6200, and the power barely falls off all the way to the rev limit. It just keeps pulling hard. The HP gain for example at 6400 rpm is huge, usually 30-35 hp over the stock chip. Jerry Woods recently sent me his dyno data of a stock 88 Carrera with SSIs and a single out Dansk muffler comparing my chip with the stock chip on his Superflow engine dyno with 91 octane. He measured a 30.2 hp gain at 6000, a 26.2 hp gain at 6250, and by 6650, power had only dropped by 20 HP from the peak. (at 5500, he also dynoed 196.6 hp with the stock chip, to 242.9 with my chip, but that is a story for another day) This allows you to when tracking the car, to stay higher up in the power band, between peak torque at 4800, and peak hp at 6200 for maximum speed and acceleration, instead of shifting earlier and having your rpms drop off lower in the powerband.

[DYB]

Steve, I did not know about option M637. Which is also interesting in comparison to the CS motor as it also had the different (lightened) valves and was balanced. I guess that figured into my query on the duribility issue.
