Have an 86.5 S3 Auto. I have heard there are no chips that really help & that drivability would be at risk if any power was improved.

Comments & advice would be appreciated.

I have driven a coupla "chipped" 928s and have been as unimpressed as many others have been. I'm sure somebody out there has a chipped 928 that has worked out very well for them, so as always, YMMV.

On an otherwise stock car, the premise of "chipping" is that there are gains to be had from "pushing the envelope" of the designed-in fuel and/or spark parameters. Sometimes, on some cars, this can work incredibly well. On many cars, it doesn't do much (5-10 HP), it ain't cheap ($600+ for 928 chips, ACK!), and if it isn't done correctly, you can LOSE power, driveability, emissions, or your whole flippin' motor (never seen it happen to a 928, but I have seen it).

On the plus side, chips could be a useful addition to a modified (cams,exhaust,heads) kinda motor, if they are done correctly. But if you have time and $, the most gains are going to come from a real programmable management system, or at least, a programmable piggy back system like the DASTEK unit.

There's more power in that thar motor, but I bet you can find more for equal (or less) $ in other areas. Rummage around in the archives here or call the 'Big 3' for some good ideas.

BTW - If you haven't done so already, you might want to install a manual kickdown switch. Instructions can be found in the archives. There's nothing like a first gear launch with no hesistation. Just a thought.

Good Luck,

Greg

Thanks Greg, that is consistent with everything I've heard. Tom

I chipped my 86.5 S with an AutoThority set. There was some improvement, but nothing to rave about. The only downside was a modest 1 MPG decrease of the average mileage. YMMV.

The chip was most noticeable during autocross events, which was why I did it in the first place. Fortunately, the chip set was under $400 at that time.

I have yet to install a chip set in the GT. Perhaps someday, if I can find a cheap set.

Thanks, Ed. By the way I am planning to drive down from Boston to D.C. in October for the Frenzy V---I've had my 928 for just a couple of months. I see you are a founder of the event. Regards, Tom

A Dastek piggyback is the best way to go. Costs the same as a chipset, but you can program it to your car specifically. If you make more changes, such as exhaust, you can then reprogram it to maximize your changes.

Thanks Doug, I'll look into it.

I emailed Devek with questions concerning their chip, they never got back to me

Sounds like they don't really have much to sell there, Dave. Thanks

Not to defend slow response, but DEVEK is often difficult to get hold of...

I used to live in SF, and they have a BUSY shop. Mark Thomas and crew do some excellent work, and as a result you can't always get them when you want them. While this is not the best from a potential customer's view, they generally have a great rep with their products and service. You might want to hit the web site, or try to call on the phone.

I just installed a set of FVD chips in my 85 928S. I haven't tested any power gains yet, though seat of the pants feel seems to have improved especially in the low end. The one interesting improvement I have found is the chips seem to have smoothed the idle significantly.

First positive reponse to this post, Thanks.

I agree, Devek is very slow in responding to questions. When I had contacted Devek, I had asked questions concerning more than one item, one item being a chip their company offers for sale. They answered the other question (one word answer), but they didn't even address the topic of their chip.
