Cummins Engine Swap, trying to make PCM understand changes
#31
Ditto...I was not expecting to see a RCSB, that thing is just going to be sweet.
As for the gauges and PCM tuning Im with everyone else on this, go pull everything you can out of a donor CTD truck, gauges/wiring harness/etc. It will still "look" stock on the inside and will probably save you a bit of time and effort trying to wire everything together.
Good luck man, cant wait to see/hear that thing rip down the street.

I can't remember what my 05 tach reads, but I think it is only 4K. The 12ver has potential of 5K, but even with 4K governor springs it will free rev to 4500 or so.

This is a great project. I thought of doing the same sort of thing with my 02 but the wife would **** at the thought of me cutting up "her" truck...lol...
I think your on the right path with the grooves in the pulley...The sensor will need to be the right distance away to read properly. The grooves need to be evenly spaced and the same depth...
Is there not a provision to access one of the timing gears on the 12V???
You could pull a signal off that and see what the duty cycle of the sensor output is??? Or how about the torque converter or flex plate???
Re-number your tack when you get the signal off something and you can make it read what ever you want... There has to be a graphics shop near you that could make a custom overlay???
I'll figure more later it's almost bed time and it's been a hella weekend...
Cheers and good luck...

Update. The cuts in the balancer has worked. Perfectly. Now it still starts and stops reading when it feels like it (key cycle). If you start it and it works, stall the engine and it will not work again until it decides. This is in the software I am 99% definate, we are waiting on a fellow that told us he would bring up a DRB-III to read the PCM.
Good idea on the overlay, but it reads right. Later in life this engine may see 5K, so we will leave it alone. Chris

I have seen pix of another conversion like this. My hat is off to you also. No help, as I don't know much about the PCM wiring, but I can't help but admire the project...
