dstinch thanks for the reply and heads up I don't need one yet but have a spare ecm with no chip and I always like to be prepared jim:texas:

anyone know where to find a chip for a 87 4.3 v6?

Just a FYI.. if you need a custom prom/chip for a OBD1 computer (anything prior to 96 as I recall) you can have one burned specifically for your application at Howell Engine Managment in Mich. will burn as detailed of a chip as you give data for. I sent them my VIN and the parameters for a Holley TBI injected, hydraulic roller, stroker motor I built for my 94 4x4 I use to tow the trailer with. They will burn a chip with all the necessary crap (w/gear ratio / tire size change if any for the speedo) engine / trans / chassis managment with (or for offroad without) EGR, spark managment, ABS controls... everything. It's not anything a lot of shops can't do with a burner, but these guys seem to hit the nail on the head first time and not a bunch of swapping back and forth trying to get it right. I hope they survive the woes in the Auto industry. I know they were obviously dependant on the "Big 3" which is now down to what?? the "big 1-1/2". If you need a custom chip definately give them a try.
