OTCs are nice, I have a couple of 2000s for my OBD-I GM cars. Also DiaCom and Moates PC cables with C.A.T.S. software. Been playing with car computers for a while now but old school UV Proms. Flashing sounds lots easier (if can avoid bricking).
For the Heepderow (my first OBD-II) I have an OBDwiz cable and CD for my netbook. $29.95 + free shipping from Amazon.
Below is a screen shot, am still tweaking the display a bit to get more on the screen & need to find the Chrysler codes for the tire monitor. Then will be putting together some playthings like a SRT type 0-60 timer - easy with a clock and MPH readout. This is going to be phun.
Been doing a little more testing and suspect the coolant sensor may be reading a bit high, oil temp may be more accurate. Will find out more precisely when the new thermostat assembly gets here (on back order). Wouldn't mind if does read high, would bring some things (including the fan) in earlier. Easier than programming.
Sometimes it is handy to play games with sensors, some companies have made names and a lot of money just messing with the IAT. However there is no substitute for a little reprogramming (my Reattae all have 180F thermostats & bring low fans in at 185F and high at 189F. Everything under the hood and in the engine lasts longer. Running cool is important in a Florida summer.)
Of course while I know GM computers, I don't know Chryslers. Never needed to before. (but if a tire shop can flash, it can't be hard to find out).
statements can you confirm ? Yout wants to know.
