Performance chip?
 

I am looking for the best performance chip I can buy for a stock 3.6 993, any help would be great.

Hi:

Please e-mail me. I have quite a few different chips for 993's.

As I understand it, only the 1995 model can be chipped. After that, they were OBDII, and need to have the DME re-flashed if you want to change the programming. Do you have a 1995?

Thanks for the reply, I have a 92 3.6 engine, I am in the process of doing a 3.2 to a 3.6 conversion.

A 92 engine is a 964, not a 993. They're all OBDI, and can be chipped.

I have a 1993 964 motor, and I run a No Bad Days chip in it, which has the unique characteristic of having two chips worth of data burned onto a single, dual-capacity chip. There's a switch on my DME box that allows me to go with either the stock mapping (safer for the engine, for day-to-day driving) or the more aggressive settings (more power for when I need it) whenever I want. Dyno results here.

Steve Wong makes a chip for the 964 engines (as well as the earlier cars). He's a regular on this board and about the most helpful guy around. Plus top notch products

chip mod dyno performance
 

has anyone ever run a non-bias test covering modified chips?

Re: chip mod dyno performance
 

Good Question. There seem to be two chip mods out there.
"A" one fits all approach, and
"B" customized for a particular magilla.

I would also love to see something where, for instance,
you take "a car" and a dyno (or for fun terms "a rolling road") and plug in all the "A - one fits all approach" chips and
see how they all perform. Get the data with the experts pro's and con's in a constructive way. Lot's of improvements with that outcome for the chip producer and the end user.
Just as long at the end result does not send us all to Cosco or Sam's Club.
