KitCarlson EMS Poll, How many should I build ??? Options

[KitCarlson]

Hey,

I know this question has a difficult answer. (IMG:style_emoticons/default/huh.gif) I would like to know a ball park number of EMS units to build in the first release. I need to order the mechanical parts and work with a contract manufacturer for the board build. Setup costs can be a significant cost for small orders. Lead time is also a concern.

Why is this question difficult? You are being asked to suggest to me your potential interest without knowing the exact cost or performance of the system.

The beta test unit is not yet in operation due to Brad's move. It was my hope to have un-biased tests in progress at this time. (IMG:style_emoticons/default/ohmy.gif) I have been working on the system full time since the start in October. The next step is to be production ready.

For those wondering what is the EMS. It is an engine management system that provides direct ignition, fuel, idle, and turbo boost control for VW and Porsche engines. It uses a special optical distributor sensor means to avoid the mechanical difficulties in crank/cam sensors. The ignition timing is electronic. The unit provides an easy upgrade for the D-Jetronic or L-Jetronic systems. The system will be sold turn-key with all parts and harness.

Please use a personal message to suggest your interest. I will answer questions you may have.

I really appreciate this BB that works to unite all 914 owners, and a means to conduct this poll.

Yes on L-Jet conversion PVC and cone filter to replace vane meter. Also need to add air temperature sensor to intake, use D-jet sensor.
