Chip Programming Issue
Today the weather is nice and I wanted to go for a drive. I took the truck to the car wash. I sprayed it down and got it all cleaned up. Started the truck up in tune 1, thats how I have always started it. I flipped it to tune 4, my economy tune, and tried to leave. As soon as the truck had a load on the engine, it would stall out. I went back to 1 and started it to see if it would drive there, it started just fine, but thats all it did... Still would not drive. I decided to let it idle for a while, and after letting it idle for about 5 minutes, I was able to drive away. The problem is now, the chip will not go into tune 6, I can go through all the tunes, 1-5 and it will change the settings and everything else, but it will not go past 5. I unplugged the cable from the EX switcher, and plugged it back in and nothing changed.
Curious what could cause this? I don't think it is water in the PCM or anything, I did not was the engine or anything, just the out side to get all the mag chloride off of it.
its a DP F5 with the EX electronic switcher.

Sounds like you got a bad connection on the PCM?
Did you pull the PCM to clean it?
I only use a stock tune to turn my truck on in cold weather.
Then i switch to my high idle, cause it drops the idle down a bit from where it would normally warm up at.
Now just to turn on the EPBV switch setup thing.
Wait, off topic, Doh!
Could you explain the whole "no go" when you changed settings?
Could be a bad switch too, I know my PHP chip came with a really high quality switch.

You might just have a bad connection on the PCM.

contacts at the PCM were cleaned. not sure how it would work on the first 5 tunes, but not the last one if it was a problem with it connecting to the PCM.

Well i reset the EX switcher, and programed it to go to another setting. Now it will go into tune 6. Not sure if it is the same as tune 5 or not, but I will find out when I drive it here in a bit...

I was trying to say earlier before my internet crapped, that you might just have a bad switch.

i had to reset that to go to the other tune... And i bet i figured out my stalling issue too, i think my back tank may be out of fuel...reads about a 1/4 tank, but i put it to the front tank and after I did that, it never stalled...
