Hi, Kelley....no, I did not get it to read
correctly. I just got back from the machinist, who made a bushing/adapter for me
so I can use another stock Mazda water temp sender. The stock Mazda temp sender
works well with my engine monitor, so I will just have two of those. I have a
1/4"NPT hole that I had previously drilled and tapped right next to the stock
Mazda water temp sender, so I had an adapter made that screws into the 1/4 NPT
hole and the Mazda temp sender screws into that. I installed it today, but ran
out of time to work on it, so I will attach the wires tomorrow. Paul

Paul,
Did you ever get that "VDO" sensor to read right ??

Hi, all....I just installed a M10x1/0 VDO
water temp sensor in the water temp location next to the oil filter. Hooked
it to my AV-10 engine monitor, and readings are incorrect. Prior to starting
the engine, my ECU indicated 26C (78F), but my engine monitor indicated
148F. Then I ran it for a couple of minutes to see if the
temps would climb, and they did. The ECU temp went up to 32C (89F) and the
engine monitor display read 160F. I will go into my AV-10 engine
monitor manual and try to find out if it requires a different sensor than
VDO, or if it can be calibrated, etc. It worked very well attached to
the stock Mazda water temp sender located on the water pump housing, but
that is when I mistakenly shared it's connection with the ECU. When
the engine monitor read 230 degrees, the water would in fact be boiling and
spitting out the overflow tank, so if it wasn't totally accurate, it was
obviously very close. Engine is still running great, however, so
there's hope. I just would prefer both temp displays working properly
before flying it. Take care. Paul
