Finally got around to installing my Steve Wong chip. The job itself was relatively simple, it took about 45 minutes, as I had to take the seat out.
It fired up straight away and settled to an idle of about 900 may need adjusting. Interestingly I removed an old performance chip - mo markings apart from a clear bubble in the centre of the chip. Any ideas what this maye be? I immediately noticed that it was much smoother at idle. The change in performance was not as big as I had hoped for, due to the existence of the other performance chip, but there was still some definite improvement in power. The big wins are the much smoother application of power, an increase in low down torque and around town drive-ability. When pushed it no longer backfires on a trailing throttle (YEAH) and the new increased limit of 6850 is fantastic. I am impressed in the smoother application of power and pick up from low revs even in third. Thanks Steve a great product - I can't wait until my longer drive in the morning.

I've got mine waiting patiently to be installed, once she comes back from a new windshield and lowering. I've got a Euro pre muff and Dansk sport muffler waiting to go on as well. Sounds great DJB, I'll post and compare to my stock 85 TL Coupe.

I had the opportunity to call 911 Chips yesterday and found myself talking with Steve Wong. What a great guy to speak with. He answered all my questions about the chip I ordered for my 85, and then the conversation turned to other Porsche related items. Mr. Wong is sincerely interested in his customer's satisfaction. I would recommend Steve to anyone needing his type of product.
Thanks again Steve Larry

I too had the experience of talking With Steve when I ordered mine. Guy had a hell of a cold and still impressed me enough to buy one to repace the current autority chip. I haven,t had time to install and check results but thats the goal for Saturday and I'll report my findings.

I had one of those early chips with the window also. I think I got it from Power Haus, Arizona about 5 1/2 years ago . It is a very good custom chip! They just don't burn them anymore, they use Autothority. I tried quite a number of other chips and until Steve started marketing his chips the old Power Haus chip was IMHO the best for my '87, very strong mid-range and super in the high-end.

I have an 84 cab,
anyone have any idea on how much a chip for this would cost and what it would do to my stock cab?? |

Kudos to Steve Wong and his chip. Just put the chip in my 87, definitely more responsive, pulls great in all gears. And this is before the pre-muffler and Sport Muffler go on. Steve is also great with customer service, ask a question and get a quick response. Pleasure to do business with. Best performance mod I made to the car. Steve, keep up the good work!

When considering a performance chip check out these websites;
www.autothority.com www.giac.com www.weltmeister.com www.upsolute.com www.andial.com For a very good insight about how effective performance chips really are, go to the the Andial (Porsche Factory Racing - USA) website (www.andial.com) on the FAQ page and read Question 2. Their discussion of performance chips is very robust and thorough. They answer many issues and refute most of the claims being made by performance chip suppliers. Andial represents Porsche in the USA for racing and provides engines for all key USA races, e.g. Daytona, and helps with Le Mans cars. They know Porsches! Have Fun Loren '88 3.2

Got my new S Wong chip installed, replacing my Autothority
chip and now I have a surgeing motor at idle from 950 to 1200 rpm. Anyon else have this problem or know of a fix? I have always been proud of my dead still idle in my 87 carrera and now its embarassing to drive. The Wong chip feels slightly smoother but I stumped at the surgeing.

Keith,
Check the idle stabil valve just back of your fan. My 3.2 did the same thing before I replaced the valve. Ran with one of Steve's chips in my car for over 2 years and loved it! Really nice guy and great product! JoeA

The idle valve should not be a problem, the result of just a chip change.
Put the old chip back in and see if the problem goes away. Don't start trying to fix problems that aren't really there by replacing good parts. The chip has either made the mixture too rich or the timing is too advanced. Like the saying goes; "There's no free rides in life." The "extra" power (?) now comes with a driveability price.

Chip Nazi, I went ahead and read the FAQ #2 on the Andial site. If what they say is true, then they make a very good agrument for Steve's chips. Steve claim's a modest 6-8% gain from 2000 rpm to redline, providing slight changes to each chip he offers based on the owners particular configuration of exhaust, intake, or other mods. Most like myself are probably combining his chip with other mods, something that goes hand in hand with the engine management software. Sounds like a better deal than using another chip supplier who offers 1 chip.
And if you reread section 2 of FAQ #2 it will say this: "The optimum air to fuel ratio is 14 lbs. of air to each lb. of fuel. Obviously, the challenge is to maintain this ratio consistently throughout the power curve as the volume of airflow increases." So then we could deduce that it makes little sense to remove the oxygen sensor from the DME feedback loop when not at full throttle, something that you have frequently advocated doing before using a performance chip... ***edited for spelling error

The optimum fuel air ratio is less than 14 for max torque. Any literature you
read will indicate this. Andial's intent was to indicate that excessive fuel which results in a air/fuel ratio WAY less than 14 has no value. It's always difficult for some people to accept the facts especially when they've possibly wasted their money. As I've said before, if it makes you feel good, then be happy with your purchase. There are many other Porsche owners who value reality. Speaking of the O2 sensor, check your CO with the "chip" and you might find that it no longer has an effect. Some chip users have indicated that their engine no longer "hunts" at idle. All 3.2s and SCs have a about a 50 rpm swing at idle when the DME reaches the two O2 limit points. The chip probably has the O2 disabled to get the better throttle response. You guys really don't need to name call. Why not try and present some logical rebutal in the future? I've yet to see any from anyone. As the saying goes; "You can lead a horse to water, but you can't make him drink." Have Fun Loren '88 3.2

Keith,
If cleaning the Idle Stabilization Valve doesn't help, then you must adjust the idle manually. Assuming your CO% is good (per the Porsche repair manual), you adjust the idle by disabling the ISV and then adjust the base idle screw on the bottom of the throttle body. CW reduces idle speed, CCW increases. To disable the ISV, you need to jumper the socket in the electric panel on the left side of the engine bay. The socket is a round one with electrical pins in it, located at the front of the elec. panel. According to John Walker, a round black relay from the fuse panel in the front trunk is the perfect fit and works to jumper the ISV. Or, you can make your own jumper wire and connect the two necessary pins (referred to as pins "B" and "C" in the Porsche manual) in the socket. These pins being @ 1 o'clock and 6 o'clock on the socket. With engine at operating temp., bridge pins B & C and set the idle to the desired 880 rpm spec. for your 87 3.2. Then remove the bridge and see how the idle responds. After you enable the ISV again, the idle will most likely change (mine dropped). The dash tach is not 100% accurate so that could be an issue. But, according to JW, the trick is to keep checking the idle by disabling ISV, setting the idle, and enabling the ISV until the idle doesn't change when you have the ISV disabled or not. This procedure should solve your idle surging, assuming everything else is in proper working order. Others have recommended adjusting the idle by simply adjusting the idle to the desired value when the engine is at operating temp. I tried this and it didn't work for me. I got a surging idle doing that, and man is it annoying when it surges!!! So do it right and disable/enable the ISV when adjusting the idle speed.
