anyone know of a better datalogging system? cost? i looked at autoxray site but cannot find the cost of just the program? seems to offer along with scanning tool only or upgrades?

 

This is very popular on this board. Check out http://www.ttspowersystems.com/diagnostic.htm

 

thanks i will give it a try in spring. think my existing XP and RS usb to serial adapter will work with it?

 

I use XP Pro with no problems. Don't know about the adapter, my laptop has a serial port but I don't see why it would'nt work. HTH

 

i just checked their platforms i think they begin 1991 model year for TBI truck. do you know if that was a 7747 ECU? that is what is in my car and not sure what year truck it ran in. i recall 1987-1989 or so. not sure.

 

7747 1987-1991 truck.

 

Please define "better" because if you're looking for increased speed then you're SOL. Not to mention winaldl being free makes it (in my opinion) the 2nd best, first being Lockers and Diacom coming in right behind winaldl.
Until the speedreader comes out there's only DIY ways of increaseing the c3 ecm's data-aq power.
