Please one for me as well should this move forward. Would be interested in assembled board or with bag of components. Thanks for pursuing this!

I can provide a bare PCB along with a bag of parts (Heathkit style) or an assembled board.

In order to make it easy to solder for the DIY folks, I will design it with all through hole components instead of surface mount ... Old School

Don't want a single $ above and beyond cost + shipping.

Yes, Heathkits. I was the youngest certified Master Builder in Heathkit history. I used to build the kits for the showroom when I was about 10 yrs old.
I could build a kit in 1/3 the time of anyone else and never had an assembly error.
Rather than cash, I was given kits as payment. I still have some Heathkits from the 70's still in boxes, along with a dozen or so assembled units.

Since Larry is dead, I plan on using him for assembly labor

I am not looking to make any profit from this, so it would just be cost + shipping.

I will double check with the Admin (Bob) to make sure there are no issues.
Lewis, what a great idea. I know you are a whiz at this, and this truly exemplifies the Rennlist Spirit. Well done! I am copying your post as well Flying Low's to the DIY forum. Thanks to you both!

OK, just heard back from Bob (RL admin) and there are no issues or conflicts with me doing this.

So, this weekend should be schematic capture, library work and PCB layout.

I will ask one of the Mods to stick a thread at the top of this forum to act as a list of who wants one and in what configuration (kit or assembled).

I will source all the components from DigiKey and the PCB from Advanced Circuits, so there will be full visibility into the parts cost.

What other parts does one need to remove the OBDII SAI system? Aren't there a couple of plugs or something?

I could REALLY use one right now for a '97 M3. The only readiness indicator not set is the SAI and I've replaced the air pump and check valve.

I'll take one for the 993, will post in the order thread when it gets posted.

Thanks a million!

I'll take a kit. Would appreciate any suggestions on how to learn soldering.

Thanks Lewis!!
