Steve Wong chip WOW
 

Just installed one of Steves' chips on my 87 3.2. I had just put on the dansk pre muffler about a week or two ago. I noticed a bit of difference with that but now that I have the chip to match it's like a different car. much smoother idle even from a cold start. It was doing a little hunting for a few seconds before the chip now none. chip did everything he said it would. I was REALLY amazed at the difference in my part throttle response. also none of that little bucking when you let off the throttle in second or first. that was a nice bonus. OH and putting it in was a breeze the instructions are very detailed. I'm not that computer savvy,and was just this side of terrified of actually messing with the dme myself.but it was very easy. THANKS Steve Great product!!!

Welcome to the club...

Is there a Wong chip for 964 3.6 motors?

Steve knows what he is doing. I have two of his products and they are worth the investment.

I have an SW chip - my car was on a dynamometer yesterday (a very reputable set up here in the UK) and returned a peak of 245.7hp.

The car is completely std apart from the chip.

To say I was pleased is an understatement!

(Sorry - edited post. Getting carried away and juxtaposed my 5 and 7!)

Over the years, so many positives for Steve's product. Looks like this spring I'll have Steve's name written on my new chip.

Glad to see another happy customer of Steve W. I was amazed at the difference especially on the low end side and overall drivability.

Welcome to the club.............:D

Yup!

Thanks guys, glad to hear it's working out!

Yes, from stock to full race. Here's a 964 motor from Kevin Roush (of IMSA/Daytona fame) we live tuned on the dyno. It was modified with 3.8L p/cs, racing cams and headers, and a ultralight clutch and flywheel. When we were done, it pulled 277 hp at the wheels (326 hp at the engine). For kicks, we redynoed with the stock RS chip 2 minutes later at 248 wheel hp, (the red curves) a 29 whp difference. If you look closely, at 5000 rpm, the engine gains 35 whp (41 at the engine) and at 6500, 43 whp - 50 at the engine.

nice, steve...this upgrade is coming to a 964 near me very soon! :)

I installed one also and HOLY CARP what a diff. Glad to see SW on the boards

I am thinking about one of Steve's chips as well. Most posts indicate that the chip improves low end performance.

When I review the Dyno results on his website it appears that there are no significant gains in HP until 5500 RPM.

What am I missing?

I have one on my 92. I noticed improved throttle response right away. It feels like it has more oomph than before.

Highly recommend.

You will feel it right off the bat. Bottom end comes alive sooner as well as the top end. Felt like a new motor to me.

Felt even better when I put some 100 octane in it.

Dont think. BUY! Sell the dog. Sell the kids! Sell the wife! BUY BUY BUY!

Now good bye:)

In general increased torque increases acceleration which is what you feel, while hp is used to maintain a top speed. Realize that dyno charts are only a measure of power at full throttle, and do not display part throttle torque gains, where you feel it most. If you have a track vehicle, hp gains are important to you. But not everybody drives their car at 6000 rpm on a consistent basis, and you don't always floor your pedal at 2000 rpm when driving on the street.

If your car is mostly a street vehicle, you'd spend at least 95% of the time in part throttle mode between 1000-4500 rpm (where the dyno charts don't show), and here is where part throttle torque gains make all the difference. It is a little understood area that defines the primary difference between the characteristics of different chips, between a chip that either feels flat or surges, or one that has instantaneous response and pull on the crack of your throttle . It is the most complex region to tune, but properly done this region is the most usable as it significantly increases throttle response, acceleration, fuel efficiency, and eliminates the sub 4000 rpm lag that is inherent in 911s.

Think of a typical dyno chart as a 2-d graph, with rpm as the x-axis, and power on the y-axis measuring 100% load. Now if there were such a thing as a 3-d dyno chart, what you'd also want to look at is the graph in the third dimension, the z-axis from 0 to 99% load, such as the following example:

"It is the most complex region to tune,"

Please!!!!!!!!!!!

Same old hyperbole! It's about a hours effort with a laptop and an emulator,
i.e. just start by copying the later Porsche chip (copyright infringement) and
then "push" that timing a few more degrees into the pinging region. But for
some who like to express hyperbole, it's "complex", hardly a real creative
effort! Those with a 911SC got the same results by using a 13mm box
wrench and slightly turning the distributor. There, it was a five minute effort
and without the "smoke & mirrors".

Check here; www.systemsc.com/tests.htm ; to see what performance tuners
do to the timing especially Supplier B who has the timing "pushed" to 44 degrees
under light loads to get the "feel".

Here we go again....... Another thread starts swirling down the porcelain fixture.....

Cheers

Loren,
Take it down the road some where else. Unless you have something other than your usual hyperbole no body wants to hear it again. Just can't stand seeing how well it works. Some things here never change. Let's all guess what the next response will be now.:rolleyes:

Another satisfied SteveW customer:D :D
