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

Wow... where does all this come from? I think the hundreds of positive posts in favor of Steve's product shows he's quite competant... and, while I don't have his chip yet, I like the way he responds positively and informatively to anyone on this board who engages him. It says alot for his character, in my opinion, which I'm sure reflects in the quality of the product he sells.

Very incorrect and it shows a lack of understanding of how 911 motors are tuned from the factory. You should be a lot smarter than that. I will let you in on some secrets. Listen and learn:

Pushing timing only serves to reduce the predetonation margin without a torque or power gain to write home about. To increase torque without endangering the pinging margin to nil levels, it requires that the factory's lean fuel programming be richened substantially upon load and throttle transients to the air/fuel ratio of best power, which is around 13.0:1 instead of the lean smog ratio of 14.72:1, an approximate 20% increase in fuel. The richer mixture does two things: a) increases overall torque, and b) increases the predetonation margin significantly which allows an ignition timing increase in conjunction without the danger of pinging. And regardless of what some may say, the O2 sensor only serves as a guide at part throttle to bring the ratios to 14.7, but can be controlled and ignored on transients, high loads, high rpm, and full throttle.

The factory also programs 911s excessively rich above 5000 rpm to keep the catalytic converters cool when at full throttle on the Autobahn for two hours straight at 150 mph. Look at the air fuel ratio log of a stock 993 for example. But for those of us who don't drive full throttle for two hours, and don't have cats, this only serves to flood the engine and reduce power. If the fuel is not corrected, again, increasing timing at full throttle at 6000 rpm, provides only a tiny increase in power. A dyno will show that if the fuel maps remain uncorrected, a 6 degree increase in overall ignition timing will only show a 3-4 hp increase at 6000 rpm. Here is where most chip tuners fail. If however the fuel maps are corrected to the optimum air/fuel ratio, combined with a ignition timing increase, the hp gain will jump to 16 hp at the same rpm point. Try doing that with your 5 minutes and a 13mm box wrench.

A chip thread simply is not complete without a benevolent post from loren. :D

steve, i have spoken to you in the past and appreciated your wisdom. i would like to purchase one of your chips for my PCA showroom stock F-CLASS 87 3.2. we have gone by the letter of the rules as far as engine mods. ie. a K & N, cat bypass, GHL muffler. nothing else as far as engine mods. we lost one (1) pt for removing cat and also we lost two (2) points for adding tarret camber plates w/monoballs to front end to gain camber for DOT "R" tires. you can loose a total of seven (7) pts. before being bumped into a modified class.

pano magazine a month ago stated PCA was really going to crack down on showroom stock due to all the cheating. after watching one "infamous" shop owner here drive all the way from phx to sebring and get "caught" cheating the second time in another class, and being kicked out of that venue, i really dont feel like wasting my time nor money cheating.

but that doesnt stop me from wanting one of your chips for roadtrips and general terrorizing the populace.

soooooooo..........can i have my cake and eat it too???? since any 15 year old car classified as "collector status" here in az. no longer has to go thru smog, can i just "plug and play " your chip? w/out any hassles? ie. today i decide to go carve the twisties and next weekend i go to the track and switch from one to the other?

thanks for your time.

Wongified my baby some time ago, still trying to get the grin off my face...

Thank you Steve, again.

Loren, why do you still bother, after all this time?
I wonder if anybody has removed their chip after reading your rant after rant after rant after rant....

I just voted by sending in an order for a chip. New tires last week, new chip this week -- the car is just about ready to go. For this week at least.

Paul

Now that this thread is on its second page, I thought I'd stop by and see if Loren had posted any of his usual whining.

Yup. Just as expected.

I swear to god almighty IM sick of Loren and the entire I hate Steve Wong issues he has.

I have yet to read a post from loren (regarding chips) that makes any sense.

Man all this talk of the SW chip really has my interest. I recently purchased a 1989 3.2 Carrera Coupe SA.

I'm getting familiar with my 911 but the thought of crisper throttle response and more torque at part throttle would be a winner.

So...all of you who have done this are satisfied? My car is stock and would like to keep it that way with the exception of the chip.

David

Hell NO BUBBA do what thar Loren says.........Crank up the timming tell she talks to ya and then backer down a hair.............................That there is pure red neck small block chevy tuning..........*****


By all means listen to steve and visit his site.

David, I've never seen one complaint about Steve's chips (from anyone who actually has one), and there have to be many hundreds out there. You might do a search, both here and on Rennlist, to confirm this. In fact not only are there NOT complaints, most seem more than satisfied with the improvement.

Hey Pelicans,

My 924s had a cat-bypass, BB Stainless and a chip. It felt really fast and responsive. So, I am considering a chip for my 85 3.2. Steve Wong has a great reputation, which says something in the Internet age. If you do bad stuff to people, it gets around.

My 1985 3.2 Carrera is totally stock. What is the most common successful and reversible mods? I hear air intake, exhaust and a chip. Can anyone chime in with their setup and what you think about it?

How about a cat by-pass only with a chip? Does the choice of sport muffler make a big difference? I am going to have to sell some stuff on Ebay to fund my Porsche mods, so please recommend something economical. <smiles>

I'll chime in here and say that installing a Steve Wong chip completely transformed the drivability of my car. It has more bhp, torque (especially in the mid range), idles smoother, fuelling is spot on, and no pops from the exhaust on decelleration.

The car was on the Dyno on Saturday. It's got a pre-muff bypass and M&K muffler + an off the shelf Steve Wong chip. The graphs speak for themselves:

I'm very happy, thanks for a great product Steve!

Cheers,

Tim.

tim, any data on the dyno before the chip?

Before the chip the car was standard apart from a DP muffler. It Dyno'd at 239 bhp. I haven't got the graphs at the moment, but should have them to hand later on this week. I'll scan & post when I get them.

My plots from the same dynamometer and on the same day as Tim. My car just has an off the shelf SW chip set for 95RON euro fuel. Everything else on the engine is stock. This is the first run I have done so I do not have any 'before' plots.

My air/fuel ratio not as 'smooth' as Tim's.

Bear in mind that Tim and Chris's cars are both Euro/RoW so factory rated at 231. No doubt Steve is the guy, we have loads of satisfied customers on our boards and the dyno we use doesn't tell a word of a lie (sadly for my Carrera 3's AFR curve LOL).

Keep up the good work SW ;)

Funny how Loren does more to sell Steve's chips than Steve could ever hope for.

My car has some extra mass air flow upgrade and a sports muffler which I was told required a different chip than what came stock. I have no idea what kind of chip is in there, but it seems to surge in second gear. I thought I read somewhere that a Steve Wong chip might fix that...am I mistaken? I don't race my car at all, just want to make it a nicer ride going through town.

I agree. Perception is reality and whether you like it or not - people believe the chip works. I am just a lay person but my 911 seems more responsive. End of story.
