Simple Digital Sytems. I just got off their website, and am curious to see if anyone on the board has used their EM3-E system.
Crank-triggered, no laptop required, etc. for a $1000. Here's their website: http://www.sdsefi.com
Any comments? SC

 

Just my 2 cents,
in general the aftermarket ones are geared to being user friendly, and a few years ago were a grand idea, because there wasn't much info on how to work with a GM ecm. In the last 3 years that has all changed.
To be user friendly, often *they* do away with lots of little tables that just make the car nicer to drive.
If your running 10s, then yes the simpler ones are easy to deal with betwen rounds.
A $100 used laptop, some logging software, and some editing stuff and for alot less then a grand can do the stock one.
Plus when a GM ecm dies you can get a spare in a junkyard for 50 and be on your way. Matter of fact I carry a spare ecm, just because I do so much *long haul* driving.

 

Thanks,
SC
