LS1b (411) PCM Swap - ZR-1 Net Registry Forums

RHanselman · 02-27-2012

Jep,

411's were not in my crosscheck when I was doing the initial research. Do you have a website you like best?

Ron,

You can go to the EFILive and HPTuners websites:

http://www.efilive.com/
http://www.hptuners.com/

Both sites have user forums and offer custom operating systems that support boosted applications. I'm sure if you poke around on the forums, you should get a feel for the capabilities.

Also, both sites offer free demo versions of their software for download. I have installed both and they have been invaluable for getting a feel of the 411's capabilities. GM really made quantum leap advances over our ECMs.

The whole code segment thing took a while to get my head wrapped around. For example, if the binary file for a 2001 Corvette is closest to meeting my needs, but the transmission that I want to use was never offered in the Corvette, then all I have to do is swap the transmission segment from another vehicle into the Corvette binary and the PCM can now control that transmission and all of the tuning parameters that apply to that transmission are now valid.

You can also look at these forums as well:

There are many others, but these should get you started.

In other news, I have brainstormed the crank and cam position signal issue and think that I have a bolt-on solution. More news to follow as I get the details worked out.

I have a PCM and PIM on the way. $59.00 for the PCM and $99.00 for the PIM. I can't believe how cheap these PCMs are.

I had a good conversation today with Jon at F.I.C. I think the injector situation can be handled. I've got several ideas and am not sure which, if any, will end up being the final solution.

Once I have the PIM and PCM in hand and my test bench is finished, I'm going to try to see if the PCM can be made to talk to my CCM. By the way, most of the dash functionality is not tied to the CCM. All gauges should work fine even if the PCM can't talk to the CCM. I think the only things that wouldn't work would be the fuel economy stuff and the engine diagnostic display via the LCD (don't quote me on this because I haven't looked into this extensively yet). If we can get the PCM and CCM talking via the PIM, then everything should work normally. The PCM has two independently scalable outputs for speed signal, so it will accomodate the signals needed by the speedo and cruise control.

Thats it for now. If you think of anything else, feel free to post in this thread or PM me. You can also contact me via the methods below.

Thanks,
Jep
