why cant i find it anymore?i finally have everything to burn chips and need some bins to compare where others have started.i'm especally interisted in bins from boosted apps.anyone kmow where to look?been reading everything i can find and see it will take many attempts to get it right but i've got all winter to get a few ready.i.ve also herd that there are timing differences in aluminum headed vette's of the same year is this true?if so maybe i should start with a vettes timing curve and go from there?that way i'll be taking advantage if the new afr heads better!
any advice is helpful

thanks pete

The curves from iron to al heads are totally different. and with boost even different still
You can run alot more timing in cruise safely with the AL heads, but need alot less at WOT, and less yet in boost.
Might look at the www.syty.org area and look at promgrammer. Some have used the 749 in boosted v-8 applications.
Small combustion chambers will be the successs to that engine

thanks grumpy,i find that info great-but i am wondering if the ecm that i have now could be calabrated to reconize boost?i have seen some info on this but no hard fact of anyone saying they have done this.hate to change out the ecm till i get what i have running great (guess i'm a sucker for small details )still looking for a stock corvette bin to compare to my current bins that i have for the t/a--just playing right now because of no way to actually test anything till spring,hopefully by then i'll have a new cam and 30 lb injecters installed

GOOD GRIEF! This bin-chip talk is to complicated for me at this moment. I have never paid attention to any of this matters and don't have a clue what ya'll talkin' 'bout. So anyway, does any of you sell a custom chip for something like 30-40 bucks?

I just put a new 2100-2300 RPM TQ Converter. I hope a 13.20 or better
