Well, that certainly is one way to do it.
If you have an oscilloscope, in the mean time you can walk through each stage of the VR circuit and find out where it is failing.
Could be as simple as the DB37. I have seen those pins fail multiple times. It truly was not the best choice for connector.

Hi boys and girls, I'm back. I got my ms3 v3.57 and the weather was bad so it never got put together and the wife decided it was time to redo the back yard so I've been digging ditches for sprinklers and conduit for upgrading the electrical in my shop, building a patio for a Gazebo and then there is laying sod.
So all is done and I have started putting the squirt together and setting it up. I loaded Aaron Cakes MSQ and was making a few changes sense I'm running a GM Throttle body and EGT Probes.
The problem I'm having is when setting up my EGT Probes, in the "Advanced Engine" section I get a conflict error saying "EGT input pin conflict - Pin already in use by - MAF", I'm using speed density and don't have an MAF. I'm using 2 channels.
EGT channel 1 = Spare ADC (ADC 13)
EGT channel 2 = Ext_Map (ADC 11)
After turning the channels off one at a time the one causing the problem is Channel 2 Ext_map. My Question is what setting do I change to disconnect the MAF so I can use the Ext_Map ADC for my EGT?

Just so everybody knows where I've been, I cooked my Daughter board so I had to send it out and get it fixed. Got the ms3/ms3x v3.57 back from Peter, the daughter board was bad and he replaced the chip.
Here is where I left off before I screwed up my squirt.
I'm for the most part getting nothing on my csv or my msl logs, but I can make everything work in TS testmodes. Here is my msq, msl, and csv.
