So for someone with a RoW/Euro engine, the SW chip is not on a priority list for biggest bang for the performance buck?

Currently have an 86 US chassis with a Euro engine/DME. The PO had it as stock intake with SSIs and an early 2 in 1 our OE muffler.

Steve has many chips for many combos, I suggest you ask him. Don't assume he does not have a chip for your setup.

Loren, thanks for all your posts, i'm now going out to buy a Steve Wong Chip, you sealed it for me. Thanks again.

I just joined the SW club! Very happy so far. I am no technical expert but I feel the difference, especially in 2nd gear.

As a youngin', I was programming M6800s at IBMs Advanced Communications Division at RTP when the Porsche ECUs appeared so I know a bit about them from a technical side. I find your deflections amusing.

Carry on... :)

KC911,
I also still work for IBM and programmed the 8051/8052 at IBM in East Fishkill, NY back in the 1985 time frame!

Cool! I've always known from you technical expertise in these "discussions", that you knew your stuff, and the funny thing is, I have learned a lot from Loren's posts over the years. I just respectfully disagree with his "theoritical" perspective as they apply to the particular chips in question. For you newcomers, go find Loren's posts back when he appeared here on Pelican...btdt "real time"...carry on :)

Updated?

You didn't mention Steve Wong in that thread, Were your comments directed at him?

Jesus Christ Loren, let it go already. You've already shown your true colors.

You're doing no favors to your already washed up reputation.

Where did you guys buy your SW chip? Any links?
Thanks!

Found a Steve Wong chip in my '84 Carrera
 

Hi folks. I recently bought a 911 Carrera Targa 3.2 from 84 (US version 930.21) here in old Germany and found a Wong performance chip inside the ecu (see picture attached) The car now has a kat bypass without a sensor installed, open exhaust and a K&N airfilter and I must say, that the car runs very good with that modifications. Spark plugs are more white than brown. :rolleyes: At the time I installed the mods I didn't know about the chip.
Now my questions:
1) The chip is for kat use, but could I run the car without a kat and the sensor? (I'm able to do so over here, because of the cars age)
2) Has the blue turnable switch inside de the MOTRONIC still it's original functions?

I asked 911chips if it's possible to return the chip and get another one, but didn't get an answer.

Cheers
Hubert

I have one of Steve's chips for my 3.6 powered SC cabriolet. I am still running it.

Compares favorably and most if not all, better to what is out there commercially out of the box. In my case it got rid of the pesky off throttle to WOT hesitation I had with a stock chip. I have tried and tested 5 different chips.

SW's chip is a good thing. More linear power and acceleration than stock, a nice little surge at mid range. I never use first gear anymore except pulling into a driveway or up a trailer ramp. I used to get a bog and close to stalling feeling with the stock chip. So I give his chip an A+.....for what you bought and what it is.

However, nothing is cheap. If you want the chip to be tuned to your individual motor and go beyond what you bought, you NEED dyno time and if you want it to matter, Steve needs to be onsite. Steve told me this. Or have real time access to the pulls...I assume, you'll need to talk to him.

I assume all of this as I only briefly discussed this with him..... to makes the changes to your particular set up. The dyno guy isn't going to do it, Steve is. Pro time is money. Steve is a pro.

I am not going to discuss how much $$ because I am not Steve. Every situation is different. But do not believe that the chip is the end all. No chip is. IT IS a good start and I applaud Steve's efforts and I am a fan.

Just be realistic, it's a slippery slope when you play this game. You have a Porsche, not your Momz AMC Gremlin. Every dyno operator has a waiver you sign. If it splatters on the rollers it ain't his or anyone else's fault but yours.

Please take my opinion for it it is....an opinion. We all know what opinons are like.
YMMV

you can reach SW at SWChips.com - Performance Chip Tuning for Porsche

google is your friend.

And, yes I know this is a 4 year old thread....

Be patient, He is super busy tuning all the racers lately does not have moment to breathe and fill orders. He will get to you, I am certain of it :D

I ordered mine on line- it was a instock unit and had it in a few days. Best investment I've made in the car so far!

Not doing anything is an option especially if you're happy with the way things are. Getting the chip reprogrammed for the specific upgrades you've got will get you a handful of additional horses and torque though and perhaps a smoother response. There's not much you can do to these cars for easy power beyond what you just did so don't leave anything on the table, get it reprogrammed by Steve.

I thought I'd add to the already extensive amount of info on Steve Wong chips. I just installed one in my '84 3.2 motor and I am a very happy camper (cat bypass, 93 oct). Prior to Steve's chip, I had a $40 Racing Pros chip in there (sold on Ebay). The Racing Pros chip was a marginal improvement over the stock '84 chip, but it was not perfect. The idle would hunt when cold, there was some occasional bucking at part throttle between 2-3k rpm, and it would always pop back through the exhaust when you let the clutch out between shifts. With Steve's chip installed, ALL of those problems are gone. It is just more tractable and refined all around. I was kind of hoping this might be the outcome, but wasn't really expecting it. Very happy!
