We finally got around to removing the Raptor 1200A and installing the Synkromotive 900A in the MR2. The Raptor has served us well over the last 9 years, making appearances in three different installs. It is a very powerful controller, but that is all, it does not allow for programming or data logging. The Synkromotive controller has been working flawlessly in our Ranger for over a year, so we decided to install one in the MR2 as well.
Initial observations are the MR2 with the Synkro has a tad bit less acceleration. On the plus side, gone is the horrible accelerator delay we had with the Raptor. This issue reared its' ugly head in Auto Cross events where you had to press early on the pedal in anticipation of the power surge....not fun.
Now to drive the MR2 and data log the results. The data logging will really help us to track the performance of our Lithium pack as well.
