These computers are sooo basic we call them ATARI computers. The right side of the computer really has no idea what the left side of the computer is doing.
Tuning it out is just clicking a check box to turn it off and unpluging it is just easier. Try it on the maf cars, if it works great, if it doesn't, hook it back up and pull out your ECM fuse to reset your computer.Your out no money.
I did forget to say its a good idea to remove the vac hose from the T-body and cap the nipple, don't have to but.

My car has been unpluged since 91. I have driven 200,000miles in this car and never had those codes after I unplugged them. Ever. Same with the 100 plus TPI cars I've worked on over the years. These are JUST controlled sensors, not feedback basically a on or off switch. The only real reason they set the code is if the "electric switch" shorts out.

Yes, there is a code for it buuuut with these electrical switches, if they aren't there (hooked up), they can't set a failure code, uuuunless the grounding switch in the ecm croaks (very rare).. I like free.
cheers n beers.

I have a 1986 L 98 with a mas air flow unit
I have the sensor in the shop at work and it measures 0.3m ohm
going to drop it in a Hotbox to see if its a analog or a switch
What temp does exhaust gas run at ?
Hot box will hit 1200 degrees
if I dont need to program it great
Will a laptop change or do I need a chip burner ?

Another vote for Mseven.
Knows his stuff more than most.
If you have other issues with your car the best tune in the world wont fix it. Half the problem with most "tuning" complaints out there.

Looking at the GM prints its a normally open contack that closes on temp rise.
it ohm out at 0.3 meg ohm. That is preety much an open circut and the ECM most likey sees faint voltage to tell if its hook up. On temp rise it closes to tell the ECM the system in working, So a 12 volt relay,hi value resitor should do the trick.
I want to see if it kicks a code out anyway.
What do I do for a living, Automation, PLC's and robots
What's the best solfware to get to look at
and change the ECM ?
I want to get more into that
thanks for the help everybody

My 86 has set no code for EGR, since I cut and terminated all the EGR wires. That was about 8 years ago.
If you want lower fan temps and don't want to spend the money on a custom chip, buy a lower temp fan switch and tie it into both fans.

That's why I like adjusting it in the computer, you can set it to whatever you want without having to go with the "off the shelf" options.
