I went ahead and had the TSB 50p ECU reprogram done last week. I believe the car now goes in to stealth mode more easily. I documented when I picked up the car and it was at 46% SOC (and two pink bars) when returned to me. When explaining (showing off) the CAN View to my local Prius Tech the ICE cut off and I was able to leave the repair area in Stealth mode to the edge of the parking lot. That was never seen in the past. Now I am not seeing the Stage 2-3 shuttering of the ICE. OK I use a block heater and that has impact, but before I pull the umbilicus in the order to do science, has anyone else seen this after the TSB 50p ECU reprogram?
it's possible. they might have programmed it to cut spark earlier. let us know if you decide to poke into this and what you find
I do not have the shuttering anymore since the tSB.. it is great..I also am able to get it to go into stealth mode easiers and have it last longer.. Scott
