I caught wind of that the other day and need to ask Ken about them.

Never going to happen for the S3’s is it ;)

Very slick, Ken’s done it again.
We forgot to mention the epic Greg v. Porken battles when we were discussing all the previous 928 dust ups in the other thread now that I think about it.

So Darien mentioned physically advancing the timing as well, is that part of the install?

What bugs are you referring to? As far as I know, John Speake is constantly improving it.

Supposedly, these are direct replacement plugin and preprogrammed ECU's for the 928's, including the S3:

I don't know anything about the VEMS ECU's, but the main thing is that this particular vendor has created a wiring harness adapter, and preloaded programs onto the VEMS ECU. If the VEMS ECU is any good, this might be a pretty interesting option.

Again, I wish that the SharkTuner was being further developed. Even just fixing the current bugs would be nice. But I don't think that's going to happen.

He did promise to upgrade the system from an "atmospheric pressure sensor" to a Speed Density system using a MAP sensor.
Do you know if that was done? In my version the vac hose goes to the black box.

For this version with load measure with a Throttle pot, there's an atmospheric pressure sensor built into the box. I didn't name it as a "MAP sensor" so it wouldn't be confused with the external MAP sensor that will be used with the Speed-Density version that will become available later.

I purchased one last night.

Sean, I’ll be glad to let you drive it before and after if you want.

Just got back from a test drive.

1) Ken is right, you most likely won’t fry the chip or board if you install the chip backwards. :)
2) Everything previously mentioned is true. These chips frankly not only probably enhance the gains from my Xpipe, they feel great above 3,000 RPM. 3, 4th and 5th gear rocket the car now. What a difference.
3) I can probably change these chips out now in under 15 mins... practice makes perfect. ;)
4) absolutely money well spent, one of the best “bang for the buck” upgrades you will get for a stock/lightly modified setup.

Thanks Ken, for the great chips and service!

MY CAR: 89 S4 Porken S4 chip, Xpipe

I wish that I did have something prior to installation to provided some hard numbers. It’s all seat feel. I drive the car everyday and it’s not my wishful imagination, as you previously attested. Maybe someone in the 928 group will post up a pre and post dyno results.
