Go fast parts on the way

Right now, "factory" straight pipe. Diamond Eye 4" is gonna be here monday. Shes gonna rumble
 
That intake setup was almost exactly what I did and it reduced the drone as well; only difference was that I plumbed the CDR into the second elbow. Only thing I have yet to solve is that it rubs the battery post.
 
I still get plenty of exhaust drone, just no turbo whistle. I think I have a solution for the battery post. I will be taking care of that Sunday, hopefully.
 
Well this showed up today

Sure is! I should be throwing it in later this week. I will need to pull the air box out, at which point I will post some more detailed photos of the slight modifications I made to make the intake work.
 
Well its about time to pick this thread up again, albeit with a change of direction. I am not going to bed doing the HX40 as planned, but rather am doing an A Team Turbo (for now) I am picking one up, along with a tuned ECM from a fellow 6.5'er in the next few weeks. Before the turbo goes on, I hope to pick up a set of injectors as well, so that the injectors can be done when the turbo is out.

I would also like to note that my Grey Standadyne PMD that is about 2.5yrs old seems to have died. About 2 weeks ago, I was driving and the truck shut down. I plugged in my then-new spare DTech, and have been running that for the last 2 weeks. I ordered a Flight Systems kit from Leroy this morning.

I hope to have some updates coming, in the meantime, here are a couple nice pictures of the truck.

Can anyone tell me if a tuned ECM from another truck will go into my truck with no issues? Both are OBD2, only difference is his is 4.10 drive ratio, I have 3.73's.

Final ratio is irrelevant. The 6.5 trucks use a VSSB to condition the VSS signal and send it out to the various components. The PCM isn't involved other than getting the conditioned signal from the VSSB for the calibration tables. The VSSB is where the ratio correction is stored and calculated. You can change that (IE: speedo correction, ODO, etc) by moving the soldered jumpers inside the VSSB or installing a set of DIP switches in place of the jumpers.

With OBDII, swapping a different PCM might work, or it might not.

Although all the OBDII trucks use the 16216588 PCM, they use different calibration by year. In some cases, more than one calibration in a single year.

For example: I've flashed a 98 calibration in a 16216588 and it ran my 98 just fine (as it should). We took that same PCM/Calibration and dropped it into a 97 K2500 (L65 like mine) and no go. Wouldn't run. No matter what we tried (I never looked into the PCM pinouts for it, so can't say if that was it). Had to buy a 1997 VDF and Cal file in order to properly alter, upload and run the 97.

Don't ask me why, I've never bothered to go that deep into it. Different pin assignments is the likely cause. Dunno for sure, never bothered to trace it out.

If you go to Wester's website and scroll through his stuff, you can see a separate calibration for each year and some have more than that per year.

At the end of the day, the answer is still maybe. More likely to work if it's the same year, but even then its still just a maybe. The more than one cal in a year deal is in later years. Around 98+.

Only way to know for sure is to plug it in and give it a try.

In that case, I would say probably not. 2000 is one of those years with a couple different calibration files. It's been speculated that GM was mucking around with the calibration to gain experience and try things in prep for the soon to be released LB7. That's just a rumor, but it would seen to explain why an IDI 6.5 has pilot injection routines in the programming but doesn't employ them. Meh, we'll never know the truth on that one....that's info that has likely been lost to time and tides. If it ever existed at all....

The PCM will accept a 1996 calibration flash and run the 96 fine after that.

Still, give it a try.

You never know.....

I can tell you with almost 100% certainty it won't work. 96 doesn't have security in it whereas the 00 uses passlock and will be looking for the signal fro mthe key switch theft module. If it was a 96 going into a 00 it should work with the security light on, but not the other way around.
