You can mount the coil packs remotely and run plug wires to them (looks like he mounted them on his firewall). Also as of yet there isn't any aftermarket coils for LS1's.

Brain is correct, however I wouldn't put it up there with the big name stand alones. It's more of a poor mans FI system. The big reason people go to a megasquirt system is to take advantage of the 2 bar MAP system in forced induction. The factory LS1 computer can only read so much before the MAF is maxed out. The smart guys use megasquirt as a piggy back system to control air/fuel instead of a full stand alone aif/fuel/spark.
BTW - MSD does make an LS1 coil but I really wouldn't see the point at $75 dollars each.
