Hi Chuck,

We are curently utilizing the GASPAR 604 which has MANY new features.

At issue is that your entire engine will need to be "rewired" to make use of it including a new RPM board.

Your looking at approx. $700 for the complete conversion w/ labor and new 5 vdc solenoids.

The cost does not justify the conversion benefits except in cases of crashes where all electrical equipement has been destroyed.

I still support the older SIMJET 2002-D2 ECU's as well. 2) of my 3) Simjets still utilize this old ECU and I have no plans to upgrade as they are working without issue after 5 years of use.

Regards,
