Hey guys,
Anyone got a data logging system running in a VZ using the obd2 port? My VZ SS is doing this funky 'i wanna stall every now-and-again' business and was hoping to kinda log what was happening at the time...hopefully so i can show my mechanic the stats of what the car was doing at the time.

I have both an iphone and a palm pilot at my disposal, but the info im finding on obd2/interfaces etc is a bit confusing. Gotta keep cost in mind, since all i wanna do is read/log the ecu/pcu etc.

Any help would be cool.

Cheers
