Hi Dennis,

 

Such a hard time tracking down those things.  &= nbsp;BTW, do you happen to know the voltage that the EC2 feeds the PCM? = ; 5v or 12?

 

Soneone mentioned that he was using the Fueltech so= I looked into it and bought one, mostly because it is a lot more flexible t= han the EC2 to help troubleshoot issues.  It also doubles as an expansi= ve and flexible engine monitor.   For $1500 it duplicates the functions of the EC2 and provides a completely flex= ible engine monitor that can use virtually any automotive or aircraft sensor= s and also control things such as fuel pumps, aux fans, wastegates, cowl fla= p motors...  whatever you can dream up.  The display is small but configurable and it is also to bui= ld multiple units on a CAN bus to provide redundantcy and additional screens= .  Plug into your PC to upload and download engine data and mixture map= s.

 

I dont have it running yet, but I mad a harness add= aaptor to keep all my previous EC2 wiring.  

 

Will let the group know when I get it working and p= rovide a full report.  In the meantime it is something to look into.=
