I had add-on fuel mamagement computers on 2 of my old Toyotas, and installed
several on FI'd vehicles as well. The carbed units used a flow sensor, the
FI'd units had a little "computer" that measured and summed the injection
pulses. Once calibrated, it was extremely accurate. The units were
beauriful, and both were stolen one New Year's Eve when someone broke into
my cars on the driveway. They were CompuCruise units, and I have a
flowswnsor left - right here in my hand - brand new and never installed.
What's it worth? I figure somewhere around $35.00 US will take it, make me
an offer - it is likely about a pound in weight.
