The Sniper won’t even go into learn mode until at least 160°. Some parameters may need to be adjusted.
I just used a Edelbrock Proflow 4 XT intake and ecu for a customers boat. Loved the intake, hate the programming. There was NO windows based tuning software, just a simple program that you put on a tablet or phone. There was NO adjustment for going into learning mode below 160 so on my dyno (that doesnt run 160) we used a resistor to tell it it was warmed up. the boats going to erun 140 so we are adding less resistor to one of the two wires going to water temp sender, it will lie to ecu and when its 60 out, ecu will think its 80/90 out and at least give it a little bit of ECT erichment but when it hits 140, ecu will think its 160/170 , Smitty

That's very creative!

OP: IO'd look into the directions for your system a little further. I was looking at the directions on the new dual quad blower Sniper EFI system and it says you can lower the coolant temp for closed loop and etc. https://documents.holley.com/199r11770.pdf

Pretty much how all of those hot rod superchips that you plug into your car works. Well done, Smitty.

I was able to find in the instructions how to manipulate the warm up temp min. Now I just need to get them in the boat and make it happen. Lots of controls available within the touch screen
