No sir, my PCM has an 80 econo tune that was burnt on it the same day as the live tuning. Rich suggested putting in a different PCM. I didn't think I could with the single shots, but he said it would run decent just wouldn't idle to well. Maybe something to try while I have the extra vehicle here. '00 excursion

 

Just to follow this up:

My PCM is in a box with a tracking number, on it's way back to Stinky. I had the tuner put a stock-ish tune in the PCM that is already tested and trusted.

What that means is - I have my stock-powered tune tested on the Hydra and it performs flawlessly with my AC 160/100 injectors. I sent the PCM to have that tune flashed, so I have plan B in the event of chip failure or the need for troubleshooting in the future.

Firefighter 1406 is going through the same gyrations right now. He had serious issues with his truck, but the PCM was flashed with a hot tune. He spent the time and money to get the truck flashed back to stock, so we could troubleshoot the raw truck. With that change, we discovered the tune was buggering his truck... and masking a possible exhaust or boost leak.

This is all to say I have trepidations about tuning a PCM without at least testing the tune thoroughly. Even then, I'm a fan of having stock power on the PCM, and using a chip to augment power. This practice permits you to pull the augmented power as needed to troubleshoot a raw truck.

I would like to have something like that to fall back on now. A trusted modified stock tune on a PCM. But I'm not about to send my PCM back to Jody. I have gotten his stock tune flashed on my buddies truck and it ran way worse than the factory tuning. It happened by mistake. We sent his PCM off to have an 80 e flashed and when it came back the truck ran horrible! Now that I think about it a lot like mine! When we called him up he said, oh I thought you wanted it flashed back to factory, my mistake. Do we sent it back again for the 80 e.

 

Rich I think that is a very good plan as far as keeping stock power on PCM for troubleshoot. Who did you have flash your PCM ? I only know of is Jody that will flash a pcm. The reason I ask is I have a spare pcm (Thanks to Frank) that I was wanting to send out to get flashed with stockish tuning. I want to keep my orginal pcm a virgin /never chipped or tuned so I can always go back to OEM tunes for troubleshooting.

Trepidations is exactly why I have never gotten a tuner or had my pcm flashed. But one of these days I am going to have to get over my fears about tuning. And just do it !!

 

Yeah... he read a post that made him roll his eyes and say "I give up". He gets frustrated when he sees adamant statements of disinformation. Speaking in absolutes implies one knows what they are talking about and there is no need for other input. He's more a fan of "I believe xyz, but I welcome feedback." This prevents newbie readers from taking a typo, a decaffeinated post (one before the morning coffee kicks in), or just bogus regurgitation of rumor as gospel - then the newbie going out and trashing their trucks with this "gospel".

How do I know this? I'm of the same mind... plus Cody told me what happened. He logged on a few more times after the frustrating event, but he finally quit doing that as well... so it's impossible to deduce which thread raised his ire. It doesn't really matter which thread it was... the post was ultimately discredited by other members.

The forum is self-correcting at this point, so we won't fall apart without Cody... but his presence is missed (at least by me). He watched over my shoulder and corrected my mistakes, and I found that very reassuring. I don't want to mislead anyone, because the cost to the reader can potentially be very high - a windowed block, a sabotaged road trip, a wasted purchase, a family's safety, etc....

I really wish he was here for this one, but I can call him if I feel I'm getting over my head. He'll be sorely missed on the forum (maybe he'll be back at a later time), but I would dread being the guy that makes him say "Every time I think I'm out, they pull me back in."

 

Bill at PHP is burning a Cody tune on my PCM. My stock-ish tune has been put through its paces and I trust it implicitly. Using that tune as a baseline with a 100% truck will allow for troubleshooting in the future. The only thing different about it from stock is the fueling... it has been significantly lowered to accommodate the single-shots with big nozzles.

Tuning was once the Wild West, but like our country... the frontier has been heavily populated and civilization is everywhere. The tuning hardware is stable, but there are two X-factors: The condition of the vehicle, and the person doing the tuning. I have done all I can to remove X-factor 1, and I strongly urge others to do the same - it makes a huge difference in your results.

The person tuning - that one is in flux. There are tuners with a bad reputation that have learned from their mistakes and improved their product. There are those who never learn anything and just keep putting out the same product. There are those who have a burning desire to solve the Powerstroke puzzle and are constantly coming up with more nuanced products. Then... there are those that rip and burn. They copy what they find and pitch it into a chip, then make money from unwitting customers. The last one is the worst... the tunes are not compatible with each other and shifting on the fly can stall the truck or cause harm to it.

All we can do is get input from those who have tuners... preferably from those who have tried more than one, because they have an expanded frame of reference.

 

I tried the ex PCM and it would start and almost immediately die. It did this 3-4 times and then would not restart. So I swapped em back around and they both fired right up. I thought it would have worked, guess there is a lil something different that won't let it continue running. Also I disassembled the accelerator pedal assembly. Not an easy task. I have a video of the internals but I'll have to remember how to post em.

Someone tell me if the link works

 

Link works fine, David. Good photography, BTW!

Has it occurred to anyone else that after a week-and-a-half, and seventy posts, Cody has yet to surface in this thread, and you might consider changing the title of this thread to something closer to the real topic?

Just a thought that might eliminate some confusion or assist someone searching this subject later.....

Yes, it does.

I'm wondering if the PATS system is the reason it wouldn't stay running with the Ex PCM.

 

TPS is very basic - nothing to adjust, but you can clean it with electrical contact cleaner.

 

I think your right. Like I said it would start for two or three seconds then die. After doing this a few times, it locked up and the service engine light came on. I didn't bother pulling codes.

 

i have a pcm out of a 2000 xlt f350 2wd zf6 that you can try if you think it will work.
