Sinr,
This stuff should be handled between you and the manfacturer, not on the boards like this. I personally hate reading these types of threads

Justin,
Don't take this the wrong way, but I visually verified one of these not working in the field and I think its this guy's. Matter of fact, I know this came up before on here and I explained exactly what I'm going to explain again.
To summarize :
When installed in his car, it would cause the pcm to see a very HIGH temperature. Like insanely high temperature. No matter what setting it was turned to, it did this.
After removing it and hooking up the IAT sensor, normal operation was detected.
Furthermore, after taking out my $1 radio shack 10K potentiometer, I was able to correctly get teh temperature to go between the -40 C and +140 C with no issues.
We both know that all this item should be doing is modifying the resistance that the PCM sees on the IAT lines. Because of the results above, there was something fishy with that gauge AND his car.
Am I going to say there's something wrong with this gauge ? No, I can't. However, I will say with a pretty good certainty that there is something with his car AND the gauge.
Now for some food for thought. I remember way back when I first got an ICCU put in my 98 by digital ken. We had a shit load of problems with the IAT. As it turned out, we had to make a modification to the ICCU wiring in order for it to work. If I recall correctly it had something to do with grounding issues in the car. My car was completely stock so this was quite a suprise for me, but maybe something similar is happening here and that is why you can't recreate it on the bench, etc.
When he was at my house and he had this problem (which i verified), I recommended that he go up to you guys in person and have you take a peek at it. I know you have a scantool (or more than one
), etc. Did you guys happen to take a peek at the replacement you gave him in the car to see what was going on with it ? IF its the same problem as before, when you check the IAT reading, its going to have a ridiculous temperature reporting from the PCM.
fwiw
