Brief Description:  Engine and EFII Ign

Dec 31, 2013. (1 month delayed)

Engine and EFII update. The engine was ready for delivery just prior to Thanksgiving but I decided to have the EFII Dual Ignition system installed at Barrett so they could run it on the dyno. With a couple of wiring issues on the dyno the EFII system did not operate at full throttle. It is believed the power source for the IGN coils (three of them) was not adequate enough to supply ample power to the coils at the higher RPM ranges. Thus causing the engine to run perfect at idle and lower RPMs but at higher RPMs it failed to operate correctly.

All the EFII parts including the ring gear were sent back back to Robert where he bench tested the units once again. He originally did this prior to shipping them out to Barrett. Nothing was found to be an issue and so the parts are en-route to Barrett. I am not sure if Barrett will have the time to dyno the engine with the EFII systems but it would be a great comparison to the mag dyno run.

Time will tell if the issue was related to smaller than recommended gauge wiring for the EFII setup on the dyno, but I am behind now on the project because of this set back. I was originally going to use the time my dad spent with us for the holidays to mount the engine while I worked the avionics. Over 1 month set back.

Robert at EFII and Rhonda and Allen at Barrett have all been great to work with throughout this and have been very responsive.
