Any table that has a mass axis that looks identical to the spark table's mass axis, would probably end up with the same new scaling, so it would go as high as you need, but would still have the same number of rows.
It might be possible to make the VE table larger, to gain back a little bit of resolution. That would mostly depend on where there's enough free space, which I haven't looked into much yet.

Also, I just uploaded release #5:

As a lot of people know I do quite a bit with data bus manipulation for LS swaps. Well NSFW caught me at a good time today and had an idea for something, as it turned out it was something I'd already done most of the work on quite some time ago. I just hadn't come across anything to use it on. I hadn't finished sorting a couple of things out at the time so I wrapped up my work on it today and it's got a rather nice look. It's going to need to be tested on a couple more clusters to make sure all the messages work correctly but I'm pretty confidant they will

Was wondering if this was going to start being able to read TCM's Looking for something that I can read and store TCM files for Zf8 transmissions.
BTW, read the thread, amazing work and stuff that we have had in the Audi community for sometime (just not the TCM's (TCU's yes) TCM's no). So much like the Subaru area, lots of open source stuff to read and modify and load files to our ECU's.
Thanks

I think your missing the point, but I'm not sure NSFW ever just came right out and made it clear how things like this could be done so let me give a better overview of what NSFW is suggesting.
There have only ever been a couple of tools that could read and write the P01/P59 that were not commercialized and heavily locked down/restricted using altered file formats(not .bin).
While commercial tuning companies started out with pure intentions they have long since abandoned the ideals and promises they built multi-million dollar companies from. What they have done over the years is make people believe that they knew everything and they were doing this amazing job bringing you so many parameters to work with and even writing you completely custom operating systems doing things no one ever thought would have been possible.
Well here we are 20 years since the launch of the P01 and every one and their brother now knows everything possible about these pcm's, the avaible COS's and every parameter that can be adjusted in every OS. The issues here is that commercial tools did such a good job for so many years making it seem like they really cared and were giving you choices; the fact of the matter is people have only seen what these companies wanted them to see or to be able to adjust. The truth is they gave people just enough to keep them happy.
For commercial tools it's a matter of the cost to develop something VS what they can sell it for or how much perceived value it will add to their product.
Now there have always been free tools to "tune" files with and the limits of what could be adjusted were only limited by the parameters that could be mapped out in the pcm's operating system. The issue was once you altered a file there was really no way to get the new "tune" back into the pcm. With out tools to flash the PCM over the data bus altering the bin file on the flash chip was a time consuming and dangerous process so there was little reason to work on anything "New" for these pcm's. Well the Pcm Hammer and Ls Droid have solved the issues that's been plaguing people for the last 20 years by giving you the option to flash ANYTHING you want to the pcm. The only thing your limited by is the hardware in the PCM itself and the avaible commands in the Pcm's CPU.
The P01 and P59 are getting a second chance to prove what they are capable of, something that's very rare for a computer this old. What NSFW has been proposing are changes he would like to make to a NEW operating system. Not a rewrite of a stock OS with some setting in it slightly altered then calling it a "Custom" OS. He's suggesting totally rewriting HOW the Pcm's OS works and what tables it uses. This seems like a foreign concept to people because it's not something you see being done on American cars. It's not because it can't be done it's because there have been tuning solutions that were deemed good enough and no one has ever put in the time to undertake a task like this. If you go look at what some of the imports can do with a stock pcm it's gonna blow your mind. Things like 2 step rev limiter, boost control by gear, pcm controlled NOS activation, altered axis's on tables for air, fuel and spark....the list goes on. The only thing the PCM is limited by is the hardware it's built on.
So when you say something like "that's not how they work" what you should be saying is that's not how the tables currently being used in the Pcm work. While I can't predict what's in store for the future what I can tell you is every thing you think you know and have learned about these pcm's could be change in the blink of an eye. Now that we have ways to read and write every possible part of the flash chip the sky is the limit on what can be done.

Rev limiter that cuts spark instead of fuel.
Progressive meth injection control.
Ive wondered about this, didn’t know this stuff already existed w/ some imports. It sounds like you’re almost describing Holley efi capabilities and ease of use but w/ an essentially free junkyard pcm.
Got a link where to purchase the Allpro cable? Only place I could find it shows cost of n/a

The AllPros are made by a one-man company, and right now all we know for sure is that he's on vacation... Hopefully they'll be available again when he's back.
I'd describe it more as "adding new features" than "writing a new OS" but maybe that's splitting hairs. Two-step fuel-cut limiters (for flat-foot shifting and launch control) should be really easy, that was the "gateway drug" that got me started with my Subaru. Spark-cut rev limiting has also been done for a bunch of Subarus - not by me, that was a couple other guys - but I see no reason why it couldn't be done here too.
Meth control is not out of the question but i'd lean toward using an external controller for that. One of the limitations of this approach vs aftermarket EFI is that we're still limited by the factory controller's number and type of inputs and outputs. For an MT car we might be able to re-purpose some AT shift solenoid outputs for other things, but I don't think there's a lot of I/O left over on the AT cars.

E-85 I did another search and found a few threads.. They were all Talking E-85 I am not going to pay $6.00 per gallon for E-85 in 5 gallon cans.. I am going to go to the local gas station and pay $1.80 per gallon for it .. There really is no such thing as E-85 it may be E-35 or E-75 also I may just add plain old gas in the TAnk when I am not near an E-85 station .. plus could mix 50% E-85 and 50% gasoline to your tank if you are not running a super high Compression ration or a lot of Boost ..
So I guess I better specify I want to build a FleX Fuel System .. In the Military they had Multi Fuel engines that would run on Diesel gasoline or Kerosene .. but didn't want confuse anyone ..
https://ls1tech.com/forums/fueling-i...onversion.html
Yes I know that GM sells Flex fuel cars .. For example a Chevy Pickup certain years makes 5-15% more power on E-85... I also noticed that the Gen V Direct injection engines don't support it so more for example the 2020 6.6 Liter pickup is non flex fuel ..
Since I don't yet own an LS Engine and have never messed with an ECM I am starting at Ground Zero .. I have been on this corrupt for one week or less.. I found a brand new Crate Engine L-94 that already has flex fuel injectors in it ..
I see this site is over 10 years old .. I see there are people on here that don't even know how to run a fuel line .. Others are building Turbo charged engines that have maps to increase fuel deliver for amount of boost ect..
I guess I don't know how to run a search for such a Subject .. Because I don't want to read 1,000 pages of comments about people that don't know how to change the spark plugs .. ECT I have been a mechanic for 45 years but on Diesels and heavy construction equipment ect.. .. The only computerized things I have messed with is my Snowmobile "Boondokcer plug in fuel control and Wide Ban Oxygen sensor added in Exhaust .. Now I a looking into a Yamaha Motorcycle where there is one Company that makes a system you can plug into the Factory Yamaha ECM with a Lap Top .. they also make one that can be plugged into the system with wide ban that learns and tunes as you ride..
GM sales people don't have a clue all they tell you is that if you change anything from the way it was when you bought it, the Warranty is Void .. I was looking at Connect and Cruis Combinations the L-94 Engine has no ECM or wiring .. I have a part # for the Engine but did not yet attempt to locate ECM and wiring which is often around $1,300 for other Connect and Cruise Engines..
I know there is a simple device with 3/8" lines in and out that you plug into the ECM which is an Alcohol Sensor .. I have no clue what else is needed ect.. If I bought the L-94 I would put a more high performance cam in it .. Eliminate the Variable Cam Timing would have to change both the oil pan and the Eliminate the Lifters that shut down some cylinders for better mpg.. ect
This is the closest to what I want .. They do at least provide some GM part numbers.. and a few specs.. Yet I have no Clue what other parts and wires I would need.. Yes I am sure that with over 10 years of posts on this web site it is hidden some where on this site..
https://www.gmperformancemotor.com/p...376525T56.html I found the specs on the L-94 probably a 2014 Model

E85 Flex Fuel Capability: E85 is a clean-burning, domestically produced fuel, composed of 85 percent ethanol alcohol and 15 percent gasoline. Ethanol is renewable, and produces fewer greenhouse gases during the combustion process. It can be produced from various feed stocks, including corn and wheat stalks, forestry and agricultural waste and even municipal waste.
