Thanks Salty. Actually in Logworks the gauge was jumping wildly. Just all over the place. The stock unit was reading fine in both. I do have the serial 4 pin 'out' going into the serial port of my laptop. I may (may) order a USB connector from IMS and use my GFs laptop. God please dont let me get caught!
And I am using the LSU-4.9 as IMS recommended. But like their site doesnt mention it being a completely different connection from the ones used on the LC-1, there was nothing in the manual about doing anything differently for the 4.9. And yes I definitely calibrated it correctly. All the lighs blinked correctly and in fact while trying to log it is steady green, like its supposed to be.
So I just dont know
