I recently installed a 911 Max chip by Russell Berry. I have had the chip in my car for the past few days. Wow, what a difference a chip can make! The power curve and throttle response could not be better. I previously had a SW chip which I absolutely loved. I think the 911Max chip may offer a little better throttle response. If you are currently using the stock chip, take it out and save it for your smog test. I have done many mods to my car, however, this is by far the best so far.

Thanks for the info.

Justin, I have the same chip as mnmasotto. The throtle response is instant and strong. It wasn't gained by advancing the timing to some crazy 30 degree number as some have thought but buy changing the fuel map. To give you an Idea of how strong the engine is now I am currently adding drilled zimmerman brakes and am only a week or two away from a full Bilstein HD / poly-bronze sport suspention build with the help of Steve Weiner. I had been driving the same roads for a year with my car acting like a slow lumbering slug when I did a cat bypass and the MaxHPkit chip. Now the car keeps getting away from me....I could let off the gas, but that's not like me. I can honestly say it's not the same car!
the quickest way to tell if you have a chip is to remove the driver's seat or move it all the way up and back, remove the four nuts on the DME computer and the one on the cable, flip it over and see if you have scratch marks around the tabs. If you do have scratch marks you may have a chip. to make sure disconnect battery. once you pry open the DME, the stock chip has a bunch of numbers on it. Mine said 1267355358. the custom chips usually have the makers name on them. I think the MaxHPkit is $300 or $350. well worth it.
EDIT: Justin, I just saw your signature...is you engine a '78 or is it an '86?
if you have no 3.2 you have no chip? She is perty though.

I'm leaning towards the idea it may be loose shift linkage in the tranny (or somewhere rearward of the coupler that's under the rear access panel).
It's still a mystery. I'm still hoping it's NOT the tranny itself. But whether it's clutch, tranny, or shift linkage... it's gonna require an engine drop I think.
And once I get this resolved.... I'm installing Bilsteins, a front sway bar, and all the other stuff so I can challenge Doug to a race.

Shannon we are way off topic here but I want to point something out. I would love to not be doing the zimmermans and I'm sure as soon as I'm done with the suspension I'll wrap it around a tree....

Thanks for the info. Do you have to do a cat bypass, and does that change things when ordering the chip?

That's your ICV or Idle Control Valve someone was probably talking about if it's a 3.2. They get carbon in them and can cause surging. You can pull them off and squirt brake or carburator cleaner in them and you might be shocked at the gunk that comes out of them. If that's not the problem you probably need the air flow meter adjusted.

I could be the chip causing the hunting, some after market chips map out the closed loop O2 sensor operation. At idle, and any time the car is running in the part throttle maps and not under acceleration the computer enters closed loop mode where it reads the O2 sensor and maintains stoich AFR of 14.2-14.7:1. So it could be a chip that mapped out this function, and didn't properly change the cold start fuel correction tables, or it could just be that your O2 sensor is bad. What Douglas said above about checking for stock or aftermarket chip is correct. My chips use the O2 sensor the way it was meant to be used. I know in other cars the Autothority chips, and variants thereof, which make up most of the 944 aftermarket chips, map this out. They also tend to run very rich in mid ranges. Ever see any black smoke coming out of your exhaust under full throttle?
If you do decide to purchase our chip products and the idle continues to hunt, I'll be happy to help you take the necessary steps to rectify the problem if the chip does not.
Regards,
Russell

Thanks Russell. When the weather gets a bit warmer, I will take our my computer and see what is currently in there and let you know.
