If you want to access this source, a 10-core cable has to be crimped into the 10-way RJ48 plug. Let me know if you want us to supply this with the system.

2. This is a good use of water/mthhanol injection. It is more commoin for the system to replace race fuel with pump fuel. I cannot see any reason why this can't be achieved. The HFS-4 is well equipped to do this job, tracking fuel flow from medium load to high. I would say yes.

Thanks for the great info and encouraging words on my goals. I think I will build a seperate 5v supply as no sense in taxing the controller if 10mA heats it up.

Thanks,
Dave
