So I thought it would be a fun project for an afternoon. I broke out my HP Tuners setup, and went to work:

When I updated the charging table, I had to modify my actual values just a tiny bit for the PCM to accept. Here are the actual charging voltages that the PCM would accept:

I thought I would be smart and actually test the results. So, prior to making the change, I fired up the HP Tuners data logger and ran a log. Voltage is tracked under "Control Module Voltage:"

Then I made the changes to the table, and ran another log. Feeling pretty good about my technical abilities at this point I exported both the before and after log data and dumped the detail into a spread sheet. I then averaged the before and after voltages, and here they are:

Stock Charging Table: 14.089 volts
New Charging Table: 14.097 volts

So yeah, my change did in fact increase the voltage: by 8 thousandths of a volt....

:oops:

Well, crap. It took me just a few seconds to realize what was going on. I run a Premier Power Welder on the rig, and guess what - it has its own 14-volt regulator.

Nothing like wasting an afternoon.....


Funny how you & I seem to forget this stuff half the time when we start to work on our rigs....

Now I wonder if there is a way to change the voltage of the VR of PPW? My guess NO but who knows.



I used to think eventually I wanted an onboard welder. Over time, however, I’ve watched folks (including you 2) who have them struggle with all sorts of weird issues. So my question is: with the new light weight suitcase welders, if you had to do it again, would you go that route?

I think Victor @gasiorv has a carnage welder for comparison sake.
