Had to look this up in my manual: "The DIYPNPF60 does not include any of the transistors Q1 through Q4."
They must be for the direct coil control, a.k.a. EDIS
With the oversize supercharger crank pulley, I have no room at all for a crank sensor.
I guess this is settled?
The DIYPNP is unique, not like the MSPNP (other than the Microsquirt Module) or MS 3.57.
All versions use the same cpu (microcontroller), Motorola (now Freescale) MC9S12C
One of my mods is a selector switch to disable the WBO2 & enable the NBO2 on the passenger side.
Never had to use it, yet.
I just found my folder with all the pics for the A/C mods.
There was a guy on the MSExtra forum that got me started.
He actually had someone machine the DIY case to the same height as the A9L.
Since I'm satisfied with it mounted under the glove box (harness just reaches), no need for this.
My advantage is it can be removed in few minutes without kick panel contortions.
