I found an old Pulsar Taximeter the other day and just for fun did a little research and wired it into my 93 IDI. It is a simple 3 wire system - 12v and a signal wire from VSS which in my case is a tan/blk wire near Master Cylinder. My intent would be, just for fun and to mess with my wife's head a little, connect this thing up and program it so it roughly approximated what it costs me to drive my diesel. Would be good for the kids to see the quarters rack up, as well, to get an idea of how much it costs dad to run them around...
Well, other than the fact that I need a pulse divider because the meter runs insanely high (starts at $2.25, did a 2 mile route around the 'hood and meter had run up to 13.00!), something wierd happened with my trans. and this is the reason for this post.
I don't know what the meter does with the VSS input, but there must be some sort of electrical backfeeding or wierd load it puts on the wiring because the trans shifts like I'm sidestepping a manual! I mean it, this thing shifts HARD. Won't shift till about 2500 and then this thing banged into second like NOW. Then again into third at same rpm. When it came time to shift into 4th or OD or whatever (This is an E4OD), It didn't; it just hung in third and the OD stalk light started flashing. I didn't want to toast anything, so I disconnected it at the next stop. Trans and truck run fine - no damage. The only other electrical factor is that I have a BANKS transcommand module on this trans. Trans is freshly rebuilt, too. Anyway, for what it's worth, I thought I'd share this... Sincerely, Andy
