FYI ...and suggestion
Upon performing the upgradethe voltages are x.5 (half) number voltages? I know I can change them, but just wondering why, and if the OS can be changed to whole volt defaults, if anything. That is what the resistor recipe calls for. :) Make them 4,3,2 and 1 volts.
i used all the resistors in the recipe but used a 27k instead of a 25k and never had to mess with the voltages to get it to work. So the way i figured it, "if it ain't broke, don't fix it."
Have you logged your voltages to determine if you are close to the border?
I did at one point but i don't remember if they were or not. When i get the lift pumps wired up i'll look at it and report back.Quote:

ill say this much i logged voltages one time and the were diffrent than the tune said and i changed the tunes to the logged voltages and the tune flip floped around i had to put them back stock at least on the dsp 5 they do.
The point I am bringing up, is that the dsp5 upgrade should result in the same voltage result for all the platforms. Unless I am not aware of a reason otherwise. The resistor recipe provides voltages very close to half on delphi vehicles. If bosch vehicles have the same 5v signal, I am guessing they are similar.
BBL tells me this.
0.35v
1.02v
1.80v
2.93v
4.35v
What do you get?
Ah, the Delphi input circuit is different to the Bosch, so it will be different. This is really the main reason to having the switch voltages changeable by the user. Much easier to do that than have people build two totally different switch types so they can match the cal values.
I got very simular voltages readings using scan tool.Quote:
