I would look into it more. The Haltech works with all the safety features on the SS and is plug and play.
I have not heard anything about the KV8 doing the same.
@Dave@DDMWorks would be a good person to ask.
Both ECM's are going to be able to run the Ecotec in the Slingshot just fine and both will make good power and have good drivability. I would pick one ECM over the other based on who is going to be tuning your Slingshot. If the tuner you pick is more comfortable with the KV8, I would go that route as you will most likely get a better tune if they are more comfortable and have more experience with a certain ECM. For most of the Slingshot community, the Haltech is starting to have a good amount of support and looks to be the better option. Jamie Roy took the time to develop a full plug and play harness and has also been working on base tunes for multiple turbo setups and doing a lot of the ground work to make the Haltech as easy as possible. We have also started working on base tunes for the Haltech that we will be sharing with the community and Jamie also. As more Haltech's get installed, soon there will be a lot of support for the Haltech on the Slingshots. Like I said though, both ECM's will do the job, go with the one your tuner is going to be most comfortable with.
Hope that helps,
Dave

We do have a nice little mount for the Haltech though, mounts it in the stock location and holds the fuse box also, just saying...

I often wonder how anything got done before the internet was a thing.
Makes me glad to be an 80's child, my generation definitely had it easy.
Facetime! What must our grandparents think... For those that still have them....? From a device just bigger than a deck of cards... Insane!
