Connect and Cruise LS3 I am doing a '69 El Camino project and thinking about doing the LS3 connect and cruise kit from GM. I see that it uses the e67 ecm and was curious if anyone has experience adding a flex fuel sensor to this ECM and does it have the tables? Does the kit come with tuning software or is it the traditional way of using HP Tuners?
What are people using for a dash with this connect and cruise setup? Is there one that just plugs into the bulkhead connector?
Looks like the transmission options are 4L60E, 4L70E, and 4L80E?
Also what are my options for fuel pump and is that in the wiring harness? I want to add injectors and pump to support flexfuel.
It looks like @Scoggin Dickey sells these kits so I would love to hear what my options are and if they could possibly answer these questions?

GM Connect and Cruise kits do not come with tuning software. They can be tuned using the standard methods used for any of the factory LS applications such as HPtuners and EFI live.
You can add flex fuel like you would to any factory LS3 application. We use and recommend the DSX Tuning flex fuel kits.
Gauges are a really large question. The possibilities and options are endless and vary greatly depending on application, budget, and preferences. I know Dakota Digital offers an interface module to connect their gauges to the OBD2 port, and I'm certain there are others.
The harness has an activation wire for the fuel pump, but you'll have to wire the relay and pump wiring in yourself.

How can you physically see any differences from an LS376/525 HP and a LS376/430 HP?
This is frustrating as no one seems to knows the difference unless you pull the cam or pop the valve cover to see the springs are different(heavy duty) from the 430HP ?
Does GM stamp on the heads or block that the cam is ASA and or this motor is a 525HP?
Thanks much, -Matt
