What PID's/ SID's/FID's are

[Leroy Eckert]

Greg: You are 100% correct about the engine data program and the Hobby element,
and I personally don't need a cell phone, in motion satellite TV, remote control
HD flat screen, iPod, Two way radio, GPS, DVD, PSP, MP3, high speed cable
internet, Xbox, VMSpc, Bluetooth, PC wireless laptop, WiFi, Broadband, Federal
Income tax, State income tax, SUI, FUI, LUI, or even a Bluebird WB-40. That is a
lot of @#$%. Beer is good!

Except for the taxes, this day and age, the above make life a little more
comfortable wouldn't you say?

Ralph, It may just be my nature but; I dont believe that all the
digital equipment is worth the worry. When I get a check engine
light; I check the engine. If the heat goes up; I back off the
demand. I have driven a good 400,000 on used class 8 diesel trucks
with as much as 700,000 miles on the clocks. Things do not often go
wrong and when they do:
1- it showes up in water/ oil heat and or performance
or
2-too late even while you watch a PC

digital stuff I see as more of a hobby.
