for those of you interested in inexpensive computers for tuning stand alone ECU's...I justed picked up a Dell C type laptop for tuning HAltech on cheapbay..win 2000/850mHz/256r...perfect for the job
small and rugged, too ... for about 230$...this was about $2000 when they came out (7yrs ago)..plenty of parts on net for cheap upgrades and software available too
Hal f10x is has real nice easy to use windows software..work with xp, 2000, and I think win98..
You don't need more compu power than this...
