Volla,
I would love to get in on this when they are ready. I also have an 88s4. Mine has 150k miles on it so I know I will need it sooner or later.

Thanks,

Cosmo Kramer

Drives really nice, can't tell the difference all all from a stock LH. Great work!

Man, I could never get used to driving on the left hand side of the road, let alone the right hand side of the car.

Awesome work by the way!

Great update. Can't wait.

I lived in Japan fro a couple years and drove a scooter there. I had to keep telling myself, "Keep Left! Keep Left!" You do eventually get used to it, but is doen mess with the head.

That must have been quite the site, AO on a scooter going through Tokyo with a 24 of beer strapped to the back!

Dan, are those the stock maps for your GT? or for an 88 S4?

Mike Frye

Dude, seriously?

You guys are some hardcore geeks!











Thank you!

AFAIK the LH maps are the same for S4/GT/GTS. There are 3 different types of EZK map, one for S4, GT and GTS.

Hi,
Any update on the progress of this ?

Thanks,

SteveG

I rented a motor bike on Anguilla, which drives right. There is not a LOT of traffic, think carribean island, and goats, but then there's not a lot or roads either, so there is some traffic. The "keep left, keep left, keep left" worked til I came to a traffic circle. I thought my head was going explode. Ahhhhh, vacation memories.

No update to the ECU. There was a severe lack of effort on my part during christmas/new years

I got my 928 back yesterday from the gearbox rebuilders, they fixed a few small things (handbrake adjusted too tight, selector cable too tight and the speedo pickup was upside down)

I updated my fuel map and the car is now in a daily drive state.

Over the weekend I will continue with the USB driver of the ECU and hopefully program the "accelerator pump" feature.

Will post update again next week monday.

Thanks man, Not pushing, believe me, I have tons of work that needs to be done on the S4. luckilly, I have my 79 running like a top.

Make sure you check the flex plate tension and clamps before you drive the car too far, lots of engine failures after gearbox replacements. Also make sure your engine oil has lots of ZDDP in it too.
