As far as ECM goes, I am looking into using a non-Duramax ECM (with the minimum number of points as possible) when I get a little more research and more of a concrete idea I will post it up for discussion.
Like I said above, I was hoping to research a little before bringing up the ECM issue, but I myself let the cat out of the bag. I even had a long winded background reply typed out that I just erased (might put it on the post when I make a dedicated thread..kinda like a history lesson of my first encounter with deep car electronics). I am still researching, but all your relies posted here has helped my creative juices THANKS!
QUESTION: I have been looking for a couple of days for the electronic specs of the Duramax injectors and only finding ohm values, does anybody know where I can find them or have them?
I think I have read that there is 2 brands of ECMs. Is there any differences between those specs for the later Bosch ECMs and the earlier Delco ECMs (aside from the different reluctor wheels)?
Are you still planning on running Duramax injectors? Cam or crank sensors?
I am hoping to not go crazy with the injectors and want to use Bosch. Most probably crank sensor as the cam is gear driven and there shouldn't be the need to have a checksum like a chain driven cam and I am not planning see 10K (or even 5.5K for that matter)RPMs . But it mainly depends on what will be needed for the particular ECM and what reluctor wheel it needs.
Why not run an LB7 turbo?
I might, just since I gave up on 6-71 blowers early on and embraced turbos, I always wondered how to defeat turbo lag and the best answer came they introduced the VVT and have always wanted to try them, just wanting to remove as many programming points as possible with making it pneumatic/mechanical controlled.
NOT even considered, I have plenty of 12Vs laying around I want to try something new and the Dmax is a sweet looking engine once you uncover it!
Is this just for a fun time waster or for practical use? You could look at 2011-14 6.7 powerstroke turbine housings
It's to be a work truck till well beyond I die, even if it gets to a "Red Barchetta" era. I will look at the PS turbos,Thanks!
No matter what you're going to be using a duramax ECM will be FAR cheaper than any standalone aftermarket ECM. To my knowledge the only ECUs powerful enough to run these injectors are Bosch Motorsport and MoTec. Bosch is cheaper at I believe the 10-15k area where a MoTec is ~20-30k from what I recall talking to S&S about one for a customer.
You can do a Duramax standalone system for around $1000-$1500 by the time you make/buy the harness, pay for an ECM file for the OEM ECM (if you don't know how to create one) and any ancillary components.
Thanks again Bdsankey for your sharing of your knowledge! I think I have an answer to the power needed for the injectors, but it is still to early to share plus I need to research the specs of the injectors and the various non-conventional ECMs I am looking at. You are completely correct that the normal aftermarket Diesel ECMs are VERY $$$$ and I would rather put that money into the engine and hope it lasts longer than the 400k these 2 engines lasted combined.
One of the things I want to eliminate is the checksum system between the modules (and the excess modules for that matter), the stupid excess wires/sensors (do we really need a hood latch sensor?) and the way the factory engineers worked hard to overcomplicate even the simple things like how they made one brake pedal sensor routed to the BCM just so it is harder to eliminate it.
I will fully bench race this down to the cent till I drop a single dime, as the bottom line/deciding factor will be $$$'s. Even though I have programmed in binary/hexadecimal in a previous life, I think there is an easier way. I might end up with a tuned factory ECM, but I think there is another way and will explore it.
Again Thanks for the replies it all helps!
