Good info, I'd be pretty pi$$ed if I kept unhooking my battery and re-setting my radio pre-sets several times just to find out it ain't gonna work anyway

 

Well it went away today. I know that it has been way more than 5 full starts (if a full start means turning the key on, firing it up, and driving it). I didn't keep track of how many times I drove it since it came on, but all is good as it went away.

 

I found this out the hard way as well. . .monkying under the hood and forgot to hook the IAT back up. . .code came up, disconnected the batteries for the better part of 3hrs and it dodnt go away. I later learned about the design of the brain box and how it retains codes and parameters.

infact there is enough memory in the computer of the HPCR's that it will remember what the engine was doing a few seconds before a catastophic failure. basicaly the computer will tattle on you, unless your like USAFR and completely nuke the thing black.

2nd gen 24 valves the battery trick works on I believe, however that computer doest save any info like the HPCR's do.

also the 6.7's have even more memory for saving parameters, and the computer also processes info about 5x faster than the 5.9's computer.
