Jan 17th, 2014. 1 hour.
The engine arrived nicely packaged in a large box surrounded by foam. It took a while to get it out of the box since my engine hoist would not fit around the base of the box and crate. I had to cut the foam out from around the bottom of the engine to get the hoist under it all.
After working with Robert at EFII and Allen/Rhonda at Barrett Precision Engine we decided to send the engine down to me since running the engine with the EFII system and the Dyno setup would have not proven anything different from when Barrett first ran the engine with the EFII system. The engine was ready from Barrett on Nov 27th. After many communications between all parties involved the conclusion to why there where some difficulties with the first engine run was because of how the engine is operated on the dyno versus what the EFII ignition system was expecting during normal operations.
My understanding to the situation was the engine run in on the dyno locks the engine in under a high load so the engine can reach temperature quickly for proper ring break in. During this operation the MP is somewhere below 24″ most of this time causing the timing curve to not be retarded by 4 degrees to more of the normal mag timing. The engine was run at 30 degrees timing and at under a high load it caused the engine to have a pre ignition event on the number 1 cylinder likely because this cylinder might have been slightly leaner than the others. Normal operation would have kept the engine at a “squared” operation and would load the engine differently. The solution to running the EFII system on the dyno is to either disconnect the MP sensor to the ECUs causing the ECUs to run at standard mag timing to to load a “dyno map software” load.
The engine was painted yellow by Barrett and we let them pick the actaul shade, we just asked for “yellow”. What color we got we really liked.
Medium Chrome Yellow
Omni MAE (Acrylic Enamel) (PPG)
Brand code: 80502
It is originally a Chrysler color and the OEM code is DT2279
