Hey guys, I just got an Apexi neo and a boomslang harness. I installed the neo with the harness this morning just to get familiar with the tool and let it run in monitoring mode.

Well as I started driving the car through a cel and it was running like crap. I pulled over, turned the car off, then it wouldn't start. So I took out the neo, the car started fine, but with just the harness installed the car ran like crap and the cel was still there. Then I took the boomslang out and everything is fine.

My question is, should one be able to drive the car with just the boomslang installed? Shouldn't it just relay whatever signals are coming from the cpu to the engine?

You need to set some settings, refer to your NEO manual.

Will do...I did set the cylinder # and etc. Since you have had it installed before, can the boomslang be attached w/o the neo?

Nope, it will not run well or at all. I know this first hand, I believe the explanation was that the Neo with the harness overrides the MAP sensor and when the Neo isn't plug in, but the harness is, the computer does not see a MAP sensor and thus runs like crap and throws a CEL.

Thanks man, that is the answer I was looking for. I guess I need to connect both the harness and neo, and do some additional configurations.
