No, sorry it works only with windows, From XP upwards shouldn't be a problem.
windows '98 should run also but you need to install some extra stuff

Fitted Geo's 1-2 Spark version II today and took it for a couple of drives and 1-2 spark version 1 was good but this is better (on turbo engine and N.A engine) as when cruising at 90 - 100 kph before the ignition was retarded to stop knock for boost now ignition is advanced as car is at zero boost or vacuum 0.1 - 0.2 bar. When the throttle is then floored for over take or hill it retards the ignition automatically so no knock at 0.6 bar boost.

Well happy

I run it off a XP partition on my MacBook using BootCamp so it does in a way...

Chris, could you please stop beïng enthusiastic about the 12-spark! Already thinking of calling in sick for work to be able to put a car together to put it in!

Want want want.......

Sorry - if something works then it deserves praise. I hear people say keep to points as best but I have driven on points, 123 standard, 123 EVO and 1-2 spark 1 and 2 in 2 different Dyanes for 10s of thousands of miles to Italy, Germany etc etc and for me geo's is the best (SORRY) and I am not on commision.

Thanks...

To anyone who had problems with running the 1-2 Spark program at some point: what was the problem, what kind of error did you get and how did you fix it?
I can't run the software on any of about a dozen different PC's I've tried, I get a windows error sound but no message or program window at all. I am trying to use 1-2 spark for a very important project at my uni and really running out of time, so any advice would be greatly appreciated.

What version of windows are you using and what version of 1-2-spark

Sounds like you may have a corrupt version or perhaps it cant see the 1-2-spark box and bombs out?

I like this very much!
It probably will be better than a stock electronic ignition for GSA? I might like a unit for me too, when you will start series production!
