First of all, this is NOT a pectel monitor. It is a GEMS monitor suited for a Pectel ecu on a Group A cosworth. The ecu is most likely a Pectel T6-2000.
The firmware in this monitor will be setup for a 3-bar map sensor, not the standard 2 bar.
It will also be setup for the Pectel ecu and not an L8 or P8 ecu. As far as I can remember we had to have the firmware of the Pectel monitor changed when we switched from the P8 to the Pectel T6-2000.
Never mind the fact that both the hardware and software of the L8 and/or P8 must be changed to add this function.
You will also need special software from Gems if you want to log and review data.

Sounds a bit too expensive to me.
