Hi, I am getting towards the end of the process of connecting my MSnSE to my Vauxhall XE engine with GSXR TBs and have a few settings that I want to check.

1st, when I connect the VR sensor to the relay board I get a reading of 2900-3000 on the RPM gauge on Megatune whilst cranking. Can this be correct as it seems very high to me? I note that it make no difference what way I connect the VR sensor and ground wires!

2nd, the AFR gauge shows 19.96 from the feed from the LC1. I think this is the free air reading and therefore normal but I wanted to check?

Thanks
Steve

Revs are defo wrong. I'd expect lot lower perhaps 500 Odd.

VR sensor is polarity sensitive.
