Yes...we were over this and you were not correct.
My 1990 nissan ecu is adaptive and the GM ecus were flash programmed within months of ford ecus being flash programmed with chrysler beating both by 2 years.
Facts are that chrysler and GM ecus are more sophisticated.
Since was the general manager of the facility that rebuilt and tested all ecus sold by standard, bwd, blue streak, and a ton of other names to the tune of many thousands per year, I think I am pretty accurate in my conclusion which is based on my personally sitting in on problem customer ecus as well as being the ecu technician who stood in for the ford guy when he was getting married/honeymoon, sick, vacation...etc
I can accurately say that have personally rebuilt/tested at least 1000 ford ecus as well as solving hundreds of "ECU issues" that were the car's issue since I would routinely send ecus from problem customers to somebody else and they ran fine.
well..the conversation was ford vs gm.....and fords were adaptive in the 80's whereas gm wasn't....till the obd2 requirements. fords had better/faster processors, they rarely failed, and they controlled the systems better than gm or chrysler.
chryslers just fail. a lot. or at least they used to.....till the obd2 requirements. i can't tell you how many dodge pickups, jeep grand cherokees, and k-cars i've towed.
grand cherokees were always no-starts, and almost always computers. when not computers, they were ckp's.
the only
reason techs don't like ford computers, is that you were unable to get datastream from them till about 92 or so. techs didn't like this, because now they had to think. oh yea....and much like todays obd2 computers will do......fords have almost always triggered lots of codes for one problem. techs didn't like having to think to figure out which code caused the rest of them.
gm's i've had to replace computers, and/or proms. it was a dumb assed system to be honest, but at least it was pretty simple to figure out.
if we go into japanese, i can't recall ever replacing a honda computer. i've done a few toyotas, back in the 90's. and lots of nissans back then. nissans were the worst. i don't recall ever replacing a mazda computer come to think of it.........
and since you(based on your statements) seem to think my word doesn't hold any weight, not a single computer i've replace has ever come back as having been a wrong diagnosis. not one. i'm not a "guesser", and i don't order a part until i'm 110% sure it's needed. this is why i'm trusted by my customers.
people that taught me now ask me for advice, which sometimes i can't help them with, although i try.
what i say, i say from working in the bays 5 or 6 days a week, and from being the guy that everyone gave the poop that they didn't wanna fix to me.
