Load by Gear - Teaser
So, the time has come to fill you guys in on something I have been hard at work on, along w/ @martial@mhd
Aside from defining new tables and building out the XDF's, some of you know I decompiled the BIN into assembly some time ago in IDA Pro and have been studying it, vs. the logic in "IS" car bins.
Well, based closely on the "overboost" feature of the IS cars, I bring to you: Load by Gear, tested and working on my regular old IJEOS 135i! It entails custom logic implemented into my IJEOS bin. I8AOS support will come, but is much harder as it's structure is much different.
The premise is simple, you set your Load Target to the lowest load you would like to run (1st gear), and then use the new "Load Target Adder by Gear" table to increase this load for subsequent gears. And unlike the "overboost" feature on 1M and IS cars, load does not decay after 1s / timer. This will allow you to put down exactly as much power per gear that your tires can handle.
Here is a screenshot of how I had these two tables set up for testing purposes (intentionally slow / pointless stepped load just for demonstration):
Worthless without logs, you say?

Ignore the sloppy PID, boost, throttle closures in the tune, it is just a base map thrown together for testing purposes
There is still more testing to take place, and getting it added to I8AOS will take some time, but I imagine porting to the 1M / IS roms should be much more trivial.

Since I have an IJE0S 335is I'm very curious how much needs to be changed just to get rid of that timer. Since I already have the overboost function enabled, is there still more than a simple value change to lose it?

Great work Jake! Is this the same Overboost table just renamed or did you find a whole new table? I assume it's the overboost table with control of the timer? This is a huge development. If you need a INA0S_IS tester just let know.

Awesome work J! Quick questions, do the values in the load by gear table have to be the same all the way down the column? Or can it have different boost values at different RPMs for one gear?

I can only hope that this may also be a foot in the door to dealing with the 23 or so PSI limit in the DME so we can use the N20 straight with the DME rather than using a JB4. If that's the case you're going to make me piss my pants in excitement.
