Installed my jb4. Thanks to the instructions here. The only issue in had was figuring how I'm going to secure the unit. I tucked in between the battery and the battery liner.
I'm on map1 and it pulls nicely.
Will stay on map1 for a while and in spring I'll switch to map2. What's nice about map 1 and 2, I can use 91 octane as per bms. Will probably end up getting the bluetooth module so I can cue gauges and make changes on the fly. The only thing that confused me a bit is the connector with the brown wires that are shorter than the rainbow ones goes to the manifold which is further.. went for a spin and all is good. Left the plug gap at .028.
