ok so i looked over the crome web site.....my ??? is if i want to run a ls turbo in a obdo car (EF) would i have to tune a obdo ecu say (pm6/7) to factory pr4 then start all over to up the fuel to the air ect......or take the obdo ecu and make big time adjustments.......thanks. o ps never have done anything with crome so if i sound dumb sorry and be gentel......

 

crome is for obd1 only. I don't think that there is really any obd0 support anymore, I know you can use turboedit but i never used it.

 

is it free do you have a site for it.......

 

o and how do i hook up the ecu to my laptop

 

you can use a chip burner and take the chip out of the ecu, burn it, reinstall...repeat one million times. I would instead look at getting a Moates Ostrich 2.0. It plugs into the ECU socket on your ECU and also plugs into your laptop via USB. It works like a charm I love mine!
