Hydra chip stalling truck
 
1997 Ford 7.3 Powerstroke - Pretty nuch stock engine (Cali model) with the Hydra. It had been running great for a few months, then a few weeks ago Truck died on me while driving. I was able to get it to the stock position and the truck ran again. Happened again yesterday while driving and switching tunes on the Hydra. Engine literally quit and I had to manhandle it it coast into a parking lot. Switched the tuner back to stock and it started again. Any ideas?

I'm sorry to hear that you're having an issue. Hopefully it's a simple fix.

In nearly every case of a vehicle cutting out while driving, there is ultimately a connection issue between the chip and the PCM. It could be from over-cleaning or under-cleaning the PCM connector causing an issue, or there could be a vibration that causes the chip to wiggle a little and lose contact.

I would suggest:
  • Disconnect the PCM Connector to kill power to the PCM
  • Removing the parking brake assembly
  • Remove the chip from the PCM
  • Take a piece of Scotch Brite and lightly buff the contacts on both sides
  • Wipe contacts with alcohol and a paper towel
  • Blow out the connector on the chip just to make sure there's no silicone in there
  • Reinstall the chip in the PCM
  • Rock the exposed part of the chip back and forth slightly (in this case, left and right) to help seat the contacts
  • Use vinyl duct tape to fasten the chip to the PCM (this prevents vibration)
  • Reattach the parking brake assembly
  • Make sure that all cables are routed smoothly and not pinched anywhere
  • Reconnect the PCM connector

This should most likely clear up any issue you are having with the stalling.

If you have any further questions, please let us know.
