T444E Boost PSI and a few other numbers
I bought a BlueFire. My 230hp, 190k mile, 33' flatnose, MT43 4 speed with 4.10 (originally 5.11) rear end does 60mph at 2050rpm.
My tranny electric modulator has proven challenging, yet we've road tested it with a toggle switch hooked up and when activated it downshifts and really pumps up the rpms.
Instead of using an limiting switch at the accelerator pedal, I added a tee to the MAP sensor port and then added a 15psi (14-24 adjustable) pressure switch to trip the modulator.
Unfortunately, when I took the bus out to test this setup, my BlueFire tells me my Boost goes up to a maximum of 15psi when manually shifted into 3rd, climbing a steep grade at 55mph and 2400rpm pedal to the floor.
Around town on the flat, with standard accelerator use, it shifts at about 8-10psi.
My plan is to get a different pressure switch and set it somewhere around 8-10psi, unless I hear something on here that changes my mind.
With rain and 49 degrees, my other numbers were:
Coolant - 195-210
Oil Temp - Rose up to 205 (seems high to me....)
Oil Pressure - 35-50+ depending on engine load
EGT - Around 500 - 700 around town, didn't check it climbing the grade as I was watching the RPMs and Boost.
My oil temp is the only one I'm really concerned about.
Around town with gentle accelerator use it runs and shifts great. On the freeway flat it runs great. When we manually activate the modulator it all works great. So, I'm not super worried, just checking in to see what you all think.
