So probably best to purchase an LS instead?LT1 has an E92 controller. Won't match any Solstice controller.
You can ready the installation guides for the LT1 crate motors here:
Chevrolet Performance Installation Guides
The controller kits are listed under LT Components. The LT1 instructions aren't opening for me tonight. I'll check tomorrow if it's working. If not, I'll bug some people about it.... For now, the LT4 uses the same E92 controller. It's 90% or more the same, you could read it for a general idea of what it involves:
