You guys seen this yet?

EFI Connection has figured out how to implant a LS crank/cam sensor into your LT or L98 (TPI) motor to run it on a full coil over plug LS1 computer - even DBW if desired.
THis is SOOOO cool, because it brings the OBD I guys back to the table with something to share.
I'm looking into it for our 1986 Corvette. It won't give you more hp per-say, but it will allow total tuning down the road which sorely lacks on the L98 E-prom systems.
Oh...and they are also setting this up for ANY old school Chevy big or small block. This is going to be devastating to the aftermarket (FAST...etc) EFI guys.
