Just before christmas we installed a hydra chip in the truck. It run great lots of power , had no issues. Just after New Years the truck sat for almost a week. It fired up an ran for twenty min then stalled. It wood fire up in stock setting but stall as soon as I switched the chip to setting one. Pulled the PCM out and checked the connection. I touched up a few just to be sure. Reinstalling the truck wood stall in stock setting. Today I pulled the chip out completely and it hasn't stalled since. Any idea what could be going on? Bad connection or bad chip. Php hydra told me in stock setting it wood act like chip isn't even in the truck and it still stalled. Even tried updated hex code an still stalled

 

It could be a bad chip. How is the switch connected to the chip? (not familiar with hydra)

A stock tune on a chip will still run off the chip so a problem with the chip will have problems in the stock tune as well.

I saw this years ago with a bad batch of TS chips that a buddy happened to get one of. Not fun to diagnose, but a new chip (switched out for free) did the trick.

 

Chips been sent back to hydra. It's far as I no basic same setup as the ts chip. They figure it's bad connection at the PCM. I wood like to find a spare PCM so I can send mine down to them and make sure it's going to work. And having a spare wood be nice incase mine does fry due to the chip. Heard a few horror stories about that. And finding one is an adventure in itself

 

Connection is almost always the culprit for a first time installer. A bad chip is pretty rare, so everyone always blames the connection.

Spare PCM's aren't too common. Seems like we diagnosed the bad chip with a loaner chip that didn't have any problems.

 

I guess I had to be different, first one successful, second on not so successful, LOL

 

What are the stats on your truck? I have two spare PCMs...

That wood be sweet if you did. I'd like to send my pcm to hydra to varify a connection issue and maybe they can get it flanged up

 

Both of mine came from a 95 5spd truck...

 

Mines a 96 5 spd. If I remember it has a 95 code according to one chart I seen

 

How soon do you need it? I'm at work right now and potentially wont be home for 5 weeks...

 

You're not alone. After a reburn I plugged the switch in on my wife's chip wrong. 1st position on the chip was high idle. I had the connector for the switch down one pin so not all of them were plugged in. The only tune that worked was high idle until I figured out what I had done. I actually thought Tony was just messing with me and had burned the whole chip at high idle.
