cam position sensor drb3 question

Hey everyone, just joined looks like a great site and glad to be here. Just installed an atk hp88 4.7 stroker. Got the sct base tune from flyinryan installed and broke the engine in today. I now need to get the cam position sensor checked with a drb3 scan tool. My question is will the scan tool affect the base tune I installed? Or would I need to reset factory settings before scan tool? Hoping somebody has done and dealt with this .thanks

Re: cam position sensor drb3 question

To my (semi-limited) knowledge, it shouldn't affect anything at all. Although I'm personally unfamiliar with Chrysler's scan tools (only really used the Snap-On Modus and GMC's Tech II), it should just be able to read your sensor info without any problems.

The only way I could see it having problems is if your tune did more than just adjust some default values within the computer (such as add new paramaters for a new part or sensor). If anything, it might have an issue interpreting manufacturer specific data and functions, but scan tools can still usually go into a "generic" mode and read the data that way. Sometimes that varies from the manufactorer specific data, but most often it doesn't.

Long story short, it shouldn't hurt your tune, but if it can't read the sensor data, you might want to go for a more generic scan tool, or see about using the DRB3 in a generic data mode.

As an aside, if you're trying to see if the sensor just works, you can use a multimeter to check it's voltage. If you have access to a lab scope you can also check it that way to see if there are any inconsitencies in the signal.
