Does your Carrera use a performance chip ?

This modification is usually half the cost of a performance chip and yields
basically the same results without problematic issues, e.g.

Well, according to this scientific study, 40 out 70 Carrera owners enjoy a Steve Wong chip.

And since I donīt hear any of them complaining - I guess I made the right choice. Canīt wait to hear from Steve!

Marcus, since you had a cat, how much horsepower do you have?

[Racerbvd]

I have used theem in the past and been very happy, my 88 is so blasted stock that I don't want to change anything, yet I really miss the low end grunt that a chip provides.

Ian,

I was kind of hoping you would miss this post, since you know how long I have been pondering this issue. Almost embarrassing.

What got me thinking is the fact that my Euro car was imported from Germany with a cat. The first owner in Sweden had it removed along with a O2 sensor I presume. I was under the impression that would need a remapping of the DME as the O2 reference is gone ??? I have no possibility finding out if that was done (if its needed). My car runs great in any case.

With a new SW chip that potential problem would be gone, right ?

One nice thing about a SW chip is that he will tailor it for YOU, and not a generic "high performance" chip. As you live in Europe your requirements may be different.

Tell Steve how you want it, what kind of fuel you have available and what mods you have, and when the chip arrives it will be for YOUR car.

Guys, lets get off of this "SW chip damages the engines" crap. If you have proof then post it and we can go from there, otherwise you are just ruining your reputation.

Congratulations Markus! I'm sure you'll be pleased. I expect you to break out the digicam and post a full how-to when Mr. Wong's present shows up at your door,

A few questions from the new guy... What am I going to spend on a SW chip, what kind of gains can be expected, and how can I make sure the PO hasn't already chipped my car? Thanks!

How do you see that? Or is that a joke?

I have emailed Steve W. and read his website. I'm sold, if for no other reason than the throttle lag. Holy butterflys, Batman, driving an EFI car after an MFI car I feel like I'm docking a boat where the input is retarded to say the least.

Or even compared to CIS. I hate to tell ya Milt, but it still ain't gonna be the same. Better, hell yes, but not the same...

Perhaps if there were an option for

"No, and I don't plan to though I doubt it will hurt anything, I'd just like to drive to work and not bother spending a couple of extra hundred dollars on something I have never wanted because I am perfectly happy with the way the car came.",

there would be fewer hits for the first one.

Wolf,

Cat was already removed when I bought the car. So 231 ponies.

Joe,

I have e-mailed Steve and he has been terrific. It will be tailor made according to my circumstances and choices. Very nice indeed !

Ian,

Oh yes ! I only hope I receive it before the salt season starts. You never know around these parts. Can be as early as in November.

[Lorenfb]

"It will be tailor made according to my circumstances and choices."

RIGHT!!!!!!!!!!!!!!!!!!!

And the car's being shipped to the USA for full dyno mapping?

Have to love that marketing and what gets "bought" into.

[ianc]

Oh look!

The broken record showed up!

Although dyno tuning each particular car in person would be a nice luxury, it is really not necessary. What is provided for each car is programming based on available fuel octane, ROW or N.A. motor, rev limiter of choice, and exhaust configuration, and in most cases this has been worked out over the years of tuning countless cars. In Markus' case, an '85 ROW Carrera to run on 95 RON octane fuel in Sweden. Such tailoring is included in the standard chipping and hardly what I would call custom tuned, although that is an available option. See here:

http://www.911chips.com/custom.htm

and here for some examples:

http://www.911chips.com/dyno.html

Custom tuning from 3.2s, 964s, and 993s can be done remotely with a client provided air/fuel log from their local dyno or a log file from a wideband air/fuel meter such as an Innovate LM-1. Since optimum ignition tables have already been worked out for each type of motor and fuel octane (91 to 100+), all that is really needed is to fine tune the fuel tables to the optimum ratio for maximum power. For custom built motors, or even stock engines, since every 911 motor has inherient flow variances from one to another, this is the best way to achieve optimum power and reliability. Code mods for lightweight flywheels, cams, or engine displacement increases are all options. Hundreds of 911s have been custom tuned this way around the world, with the results being identical to actually tuning it in person on the dyno, and are usually perfect within 1 or 2 tuning iterations.

Certainly does, along with a whole host of other bolt-on force-fed goodies

Steve W.
Hats off to you mate.
Your comments are offerred to help educate us more about choices, your products being one of them.
I always read eagerly when you post.
Only reason I haven't bought yet is that I can't decided whether I'm going to do what you did to my car, ie. bore throttle body, hone inlet manifolds, port & polish heads, SSI's or 993 HE's, sport exhaust as this would alter your chip programming I believe.
I appear to be a bit like Markus.- carefull with the dollars and only wishing to optimize what is there without visual meddling with the original car.
Half your luck Markus, at least you've finally decided............

[75Carrera]

Markus,

I put a SW chip into my 3.2 DME shortly after rebuilding the motor. The idle steadied out, the motor is more responsive and when it gets up on those 964 cams it takes off like a rocket! The power curve is much smoother and hits the cams at about 3000 RPM. I sent it back to Steve for additional dialing for the altitude here in the AZ mountains. He turned it right around and it's perfect. Steve always returns you a stock chip too in case you need it for any reason. Running hard (fun hard) the car gets a consistent 23 MPG. At standard hwy speeds it just got and amazing 28.6 MPG.
Do I like the Steve Wong chip? Well... YEA!
You can't go wong with Wong!

"Your comments are offerred to help educate us more about choices,"

Educate????????????? or Hyperbole?

Please do some reading beyond the marketing hyperbole.
There's a lot of very accurate info available about improving
performance besides the typical marketing promotional stuff,
from those that really understand automotive engineering.
