Great! Looks like it comes with both harnesses. The knock sensor harness looks different than my 5.3 LS1 harness. Going to be interesting to see how it all lays out.
The LS version of this is sequential fuel and spark right? Not wasted spark or batch fire fuel.
Going to be insterestinf to see what spark maps they have pre installed and what it's like to open the tuning up on a computer.

Also looking in seeing that the MAP sensor might not Be the same as my stock GM 2 bar. Also this is the trans control version so the fuse block and harness should be minimal.

My understanding is that it will be like all the aftermarket EFIs. Timing (base table) and then modifiers for things like NOS/Boost/ rev limiter etc. Same for fuel. Prob has Boost fuel MAP tables etc.

Yes. Not sure about tranny control and a speed output. I know it needs a VSS signal from the tranny.
Tach has an output wire signal... not sure of the signal but prob a square wave 1 rev.... like an old school tach, not like the stock LS signal which is like 2 rev or like a 4cylinder signal.

Agreed. I just think they are a small company and weren't "ready" for the popularity they would get with a 1/3 price EFI system. Its alot of bang for your buck if it delivers. and there are a TON of LS cars/trucks etc not to mention LS engine swaps. They should hire more people as you know they are now raking in the doe!
