many 0411 PCMs laying around here, trying to modify them without breaking the bank

[1NJECTED]

Team,

New here on the Forum. I used to tune cars with Holley EFI, but too many people cannot afford it due to the high cost. Therefore, I would like to consider using LS1 engine management setup with the GM 0411 computers. Now, few questions that I have. I have asked these in the HP Tuners and also EFI Life forums, but without any useful replies.

I have the HP Tuners MPVI2 OBD module here already, from a previous project. Can I use that to modify any 0411?

What software and what hardware tool do I need to change the VIN for the PCMs and remove the anti-theft system? I have not stolen anything, the 0411 is from Ebay and I want to use it in a custom build.

Where do I find 0411 tunes? Does anyone have any of these tunes available?

Last but not least, I love the Holley EFI self-tuning capability. How can I do this with the 0411? Can I log oxygen sensor readings, then adjust accordingly, and write that back onto the PCM?

Any support would be highly appreciated.

HP Tuners interface is only good for HP Tuners. Open source flashing tool is pcmhammer, that supports a few interfaces best bang for buck and high speed is obdxpro from https://obdxpro.com/?ref=pcmhacking (yes the forum will get a couple of cents if you buy from that link).
PCM Hammer will change vins, operating system if needed, and reads and writes. Free tool, no licensing costs. It also does a number of other similar generation GM PCMs.
For tunes / bins, they are scattered around this site and the internet and places like this site. In general start with knowing what operating system you want to work with and include that OSID (operating system id) in your searches. HPTuners and EFI Live file formats are encrypted and cant be used with free tools. Sometimes people can convert them to bins on request but it's not an service. They're more likely to help for a one off project you are talking about, than for a shop doing it in bulk.
For editing bins / tuneing you need either an XDF for OSID, or Universal Patcher. A good XDF for a common operating system is probably best, but Universal Patcher can search a bin and identify tables and tuneable items and can work on any supported bin. People use both options, you should look at both and decide from there.
For logging universal patcher has a logger, so does pcmhammer. They work, but are not as nice as commercial options. Neither are of the standard of hptuners. Since you already have hptuners you can keep using its logger which is free, or look in to other OBD2 logging software. You'll probably want a wideband data to see what the mixtures are doing.

HP tuners will charge you 100$ for every 0411 PCM but it can tune them no doubt
Its abilities no match to universal patcher and tunerpro but its enough for basic things like VE map or ignition timings and tranny tune and so on
So in general -yes but with additional 100$

Last but not least, I love the Holley EFI self-tuning capability. How can I do this with the 0411? Can I log oxygen sensor readings, then adjust accordingly, and write that back onto the PCM?

If you have HPT you must know about VCM scanner as a part of VCM suite
It logs all needed parameters and has analog/digit inputs to log not only engine but your wideband O2
Tuner pro and UP also can log but I dont know how to add wideband analog signal to its log

You'll still need an obd2 interface that tunerprocan talk to and a suitable ADX to log. Ive only seen broken elm327 adx but I would not be suprised if there is such a thing out there that has been made.
