My chip only does this on economy mode driving and at random no throttle response. On stock and extreme I've never had a problem. It's only a 3 position chip with a dial, older I think. But anyways wondering if anyone has a solution ?


F5 & F6 Rotary Switch - Chip Switches & Misc. - Chips, Programmers and Tuning - 1994.5 - 2003 Powerstroke 7.3L Truck - Ford Powerstroke

Looks like this without the long mast

 

Tunes are written for the PCM code, not just a generic year, model, and engine. The fact that it runs at all is lucky. You need to send the chip in to DP to have it tuned for your PCM, and for them to make sure the tunes work properly. This will not be a free service - they charge for their stock in trade, which is tuning.

Your only other hope is to clean the edges of the PCM again - maybe you missed a spot when you installed the chip.

 

The chip was in when I bought the truck. It just does it at intermittent times. No problems anywhere else. Only on economy

 

contact DP. they are very good with customer service, and should be able to get you running properly.

 

Those old switches have issues. I'm on my second one and it has problems. Mine sometimes cuts out and when it does it defaults to program #1. In my case that is high idle, which is a problem if you're under the 1400 RPM when it happens because it jumps to that RPM.

 

Being used its hard to tell how it was handled prior to you receiving it. Nonetheless, I feel the issue is a wire to the rotary **** is pulled out. This will explain why others work and that particular one doesn't.

We do have a manufactures warranty. If it worked for the previous owner it is likely from use and not a defect. If it never worked it is a defect when being made by the bots and we will replace it. However, these things do wear out over time and do need to be replaced just like a pair of shoes.

I had the exact same issue written in your response. I broke the switch down and cleaned it and reassembled. Two years now, no issues! Since I wrote about it, it will begin acting up tomorrow.
