I'm looking for some advice about what is the way to go for a scan tool. I am in need of one for a 93 corvette LT1 that I used in an engine swap. But I would like to make sure of getting something that would work on other cars I have-my 91 Sy,a 95 Northstar engine swap and possibly a 95 camaro 3.4 sfi that I used in a swap. I've never used a scan tool before so I'm hoping for something relatively simple to use. Are there any recommendations? Also,should I be after something other than a scan tool that might do much more? Thanks.
