So yes, the E38 is an ideal choice for your LS7.

Sorry we just haven't done ABS, Traction or Cruise with the factory GM ECU's so can't help with your other answers.

just found the site i was looking for ... the e38 and e67 came out at the same time and run the same processor etc... E67 has a couple more input/outputs used for variable cam timing so it says .. so in the normal conversion in Australia it is really wasted.. as we dont get the variable timing version engines (unless of course some one specially imports one)


"For 2006, GM introduced two new ECMs, E38 and E67. These controllers look somewhat similar to the E40, but slightly different connectors exist on each of the three, and none interchange. The new ECMs featured a departure from the historied 68000 series chip for a new Motorola PowerPC based 40 MHz, 32-bit RISC processor and a flash memory bumped up to a hefty 2 megabytes, or 2048 kilobytes-twice that of the replaced controllers. They are also the first GM controllers to feature floating-point processing, an improvement to the accuracy in which it makes calculations. The E67 has a slight edge on E38, thanks to its additional input/output lines, thus making it the choice for vehicles with variable valve timing"
