FAST vs. Battery Chargers and jump starts

[Warp6]

I recently had an issue with my FAST B2B not communicating with my laptop. http://www.turbobuick.com/forums/performance-ecm-upgrades/213802-ecu-not-found.htmlAfter countless attemps to connect I gave up and sent the box in. Communication chip was messed up. I'm wondering if my battery charger could be the culprit. The charger I use has 2 settings. 2 amp and 10 amp. There's also a 50 amp starter that I don't use. BTW I have never jump started my car while it has had the FAST system. It has been charged a bunch though. I'm sure unplugging the FAST or the cables would be safest but, does anyone here have any first-hand experience with issues caused by charging and/or jump starting?

I do a lot of tuning for this place local that builds street rods with blown BBC's in them and every car I do has a battery charger hooked up to it and so far, Ive had no failures like you describe.

The RS232 chip on there is a tough one and rarely fails. You are just one of the lucky ones, I guess. Charging and overvoltage issues don't really have much impact on this device on the circuit board. It's just a random failure that happens very infrequently. I think I only had to fix two or three of them ever.

Last year I went through a ton of BS trying to determine what was happening to my DFI system boards.

I had 3 major failure that still are un-explainable other than the boards would fry on the power input side. This could have a no spark issue (thank god) that would hold the injectors on while key was one FULLY OPEN. hydrolocked my motor 3 times - and the only thing that saved it was my luck or lack there of realizing what had happened and not trying to turn the motor over....

I could pull my spark plugs out and the fuel would just POUR out like a facet!

Send the unit back in several times which they repaired for me and finally after the 3rd or so time I insisted on a new unit - probably has not been back since (knock on wood).

The reason I posted this was the first time it occured I too was on a charger, but the tech folks said that was not the problem - I am still leary about using them with the unit. Pehaps there is something there that needs to be looked into a little more.........or maybe I just had a bunch of bad luck.
