Chip Switch
 

This has been happening for a few days!!!! When I go to switch positions on my chip, as soon as I bump the switch, without turning it yet, it goes to the lope idle, my water in fuel light comes on and the SES light comes on as well. Thats with out turning the switch. When I do turn it, from high idle (5) to my 80 tune (3) it lopes and seems like it has trouble "finding" the tune. Also I tried jiggling the switch (its hard mounted in the dash) and it changes from whatever tune Im in to lope which is in position 1 without changing positions. The switch is seated firm and so is the chip as well. Its just started recently. Bad switch, or am I an idiot!!!? :shrug:

Thankfully, one of the good things about the TS-style chips and switches is that they are VERY resilient to EMI and RFI (both types of electrical interference) that other chip styles are subject to.

These chips have a microprocessor that controls the memory location switching instead of a direct link between the switch and the memory chip. This cuts out the interference issues and the small voltage oscillations that occur when a switch is turned on or off. It also switches instantly so under normal switching, there is no "bump" or loss of data when going to another set of addressing allocations on the memory chip.

If you have issues with merely touching the switch....then I would say that you have a switch issue. It's just a set of contacts and a wiper....if there is an open between either contact at any time, the chip would probably default to position 1; as if there were no switch connected.

Hey guys, thank you very much. I took a video of me just tapping the switch just in case you wanted to see it. Thanks again!! You guys are awesome!! :happy-dancing:
