Ok, sounds like that would work OK. Ah! That is very good. Shutdown features are OK for an auto but not for an aircraft. Folks have fried their rotary and it still got them back to the airfield with the EC2, so would certainly want any temp controlled shut offs - shut down {:>)

Ed,

I read the installation manual on-line and it has a virtual pot to change mixture from the PDA. Also ther is a feature that eliminates the shutdown feature.

Its very interesting for sure. I could not tell, but did not see any mixture control and of course it has no redundancy. Also, I would be a bit cautious to make certain it did not (like some auto cpu have) those limp-home or engine turn off functions. Several users of the automobile cpu (for engines other than the rotary) found to their dismay that if the engine got a bit hot, it would shut down - not nice to have happen right after take off.

So, while I really like some of its features, I'll have to say I'll stick with the EC2.

Besides with my EFI System Monitor I can change timing and fuel maps on the EC2. {:>), so I feels I have the best of both worlds. Can't do data logging though.

Has anyone tried this? http://www.pocketlogger.com/index.php?pid=home also look at http://www.turnerdr.com/proddetail.asp?prod=TDR0303 and checkout the vido for stage 2 capabilities. You can use a Palm computer connect to your Mazda ECU to change injector size ignition timing and injector timing plus datalogging. Just wondering if this would work.
