ha ha ha!
Ok so it's not too dramatic, but I found another problemo
My car doesn't like mpguino, first I've got to deal with this dern reed switch of a speed sensor (yes it is a reed switch), now this!
My 87 Nissan 300zx, uses grouped injector firing paterns (injector 1 & 2, 3 & 4, 5 & 6) most of the time, BUT during cold engine operation and/or when rpms are higher than 3000, it switches to sequential injector firing (123456).
Hey, all I wanted was a miles per gallon readout on my car, not a new hobby!
But it turns out its fun so it's ok
How many other cars do this? Mabey a lot, I think it's a jetronic injection system found on many cars of the era.
We need rpm & coolant sensor input! (at least i do)
