technical question on corvette computers
I blew a rod bearing in my 97 vette A4. it has a g5x3 cam, 3.42 gears, headers, ud pulley and was tuned. IF I drop in a Ls6 motor can i use the same computer, or will it have to be significantly tuned. should I just buy a different computer? what year computer can i buy? -thanks for the help

I would just use the computer you have--You will have to do some changes on the initial tune but no whwere near the work if you were to flash a wholw new one--The more critical tables that will need changing in your computer would be the hi & lo octane timing tables--
MAF frequency table---idle tables---VE table---Most of these can be copied and pasted from a stock Z06 table-and would be a great starting point----A new computer for a LS6 would have to come out of a Z06 so it would be a M6 and would have no trans tables for your A4--You may be able to buy a blank computer but that would still be a tons of work

I think both EFILive and HPTuners post up OEM calibrations for various years and models (LS1/LS6). Your tuner should be able to go to their site and download the calibration, then copy/paste the pertinent tables into your computer. You shouldn't have to swap computers.
Oh, and I agree with what tblu posted (same tables I would copy over) except for the MAF table -- unless you also get a new MAF. If you're using your old MAF, leave the MAF table be, they are calibrated for the specific MAF you have and although some years share the same MAF, some years don't.

98's a little different, although you could just copy most of the tables from a stock Z06 file, there are some that you need to alter due to the tables having less cells in the 98 OS (mostly in the Idle tables, plus the speedo calculation is different). It really wouldnt be that difficult though. If it were me, I'd junk the 98 set up and go with a 99+newer computer and then just reflash the whole thing to whatever year/OS I wanted to use, probabaly a 01 or newer.
