my take is that you need to map that voltage output to mirror this image:

The only problem is that is for the 84, I'm not running it as an 85.5, and I don't know what values to correspond the voltages to... my MAF is in either kg/hr or lbs/hr... not the m^3/h that the original AFM used. So not only is there a conversion factor but there is the matter of the late AFM/DME combo not having a reference like the early AFM/DME combo.

regardless, the map you posted does not correlate to either. the reason i'd try the early curve first is because of the flow rate matching the voltage curve. if that doesn't work, i'd try the linear map of the later AFM/DME.

actually, now that i am thinking about it. you have a point. i'd use the later map first and see what happens. the DME is expecting that linear map corresponding to the logarithmic increase of airflow. again, the map you posted in #3 is obviously not quite right and trying the linear map is not going to hurt. save both files and start the playing.

crap....

coolant? what happened?

actually, that looks like piss....

Yeah its coolant, The damn car overheated... /: so tuning has definitely taken a back seat to this, I had changed A LOT on that voltage curve, so hopefully I have it running again soon!!

how bad did it overheat? from where did the coolant escape?

I don't know exactly how hot it was, I was in front of the car when this happened, and had my dash disassembled. /: I'm pretty sure it came out of the tank, but from what I'm hearing in the other thread I started since it over pressurized so quick I blew the head gasket.. I was using Dex Cool...

well, maybe. only one way to find out.

ok i did a compression check 180 190 190 180 :) so its the cooling system...

could still be the head gasket. but i bet the radiator cap wasn't on all the way, or something.

we need another video, BTW. this is a cool project.

so... there's the new video, lots of swearing... lots of problems...

lol a few of them fixed :)

your thermostat is stuck closed.

or it is in there backwards.

the car sounds like it is running good, so that is a plus.

Well idk if you are keeping up with my other thread on the matter, but I need to sort out a fuel injection issue, so I'm going to rob my parts car of; fuel injectors, rail, thermostat, and a water pump, as it is most likely fried.. This is all off of an 85.5

if i can peer pressure you into one thing, well two, get a NEW thermostat and, unless the other waterpump is new, a NEW waterpump. for sure a new thermostat, though. those things are cheap.

oh, and you have to pull the belts to get to the waterpump....

new belts and rollers.

i know, $$$.

Haha well that's the problem, this all started (the overheating) when I replaced the original.. I'll pick up a new one and test both the new and the old side by side, I'm going to pull the water pump out of the 85.5 and just rebuild it, a new one runs about $400 last I checked..

Well I might as well get new hoses while I'm at it... Lol and it needs new rollers and belts, I'm almost positive the pump is seized, horrid screeching when it idles super low from the 3 cylinder issue...
