Hey all,

I'm looking to swap in an LS376/480 crate motor into my 4th gen F-Body. Probably going to use the Lingenfelter 58x->24x reluctor module, and am now pondering how to deal with an initial tune.

I'm assuming that trying to drive an LS3 on an LS1 tune, even if it's to limp it over to a tuner shop is going to be tough. My nearest tuner shop is almost 100 miles from me, so a tow would cost a fortune. Would a base LS3 tune make sense? Also, how would I convert a tune from a late model Camaro or Corvette to fit my LS1 ECU? I'm assuming HPT's software is not just going to convert it for me.

Any thoughts? This is unfamiliar territory, and I couldn't find any conversion tunes in the repo.

Thanks!
