You do not. In the XDF I posted, it's included in the "misc PARAMETERS" part of the patch. After patching, if you want to go back to stock, you can just click "Remove Patch" and it will return you to the stock LT1 settings.Quote:

That patch never become public and there is no xdf in existence. Currently is too hard coded with other custom stuff and extracting is not on priority list.
The existing patch have some stock injector data for a very specific set [p/n] of injectors.
Anyone using the patch should provide and fill correct injector data to all the tables listed in the patch folder after the patch is applied and bin saved.
can you repost latest .xdf file as this link is no more validQuote:

i'm looking for XDF with SD AE patch and oil temp to trans temp fan patch you made for me and EEhack mod to play with EOIT
best regards
The latest modded eehack is available here. No need to reupload, but the xdf opens as a png dot so here it is.

Thanks
Any chance someone is willing to work on a patch to enable flex fuel interpolation? As you may be aware pump E85 isn't necessarily 85% ethanol. While here where I live it's mandated to be 85% via taxes on vendors who try to sell anything lower, elsewhere in the USA it can be anywhere from 51% to 85% and still be called "E85." So you'd want to run an ethanol content sensor on your fuel feed, and interpolate between two fueling tables depending on the ethanol content of the fuel (your normal E0~E10 gasoline table, and an additional table containing the E85 85% table). The ethanol content analyzers generally output 0-5V analog to represent 0%~100% ethanol content, so it'd use one of the free ADC inputs just like a wideband O2 sensor would.
Thanks y'all!
So, question about the LS Injector patch for kur4o. Do these three tables override all the injector-related tables in the $EE Air-Fuel Metering category? So after applying the patch I'd only need to fill in the three LS tables, and can ignore the $EE Injector Flow Rate, Injector Voltage Offsets, and Injector Offset Adder? And am I also correct that to replicate the effect of changing the $EE IFR, I would need to multiply every entry in "Fuel Flow vs Vacuum" by the same amount I would multiply $EE's IFR, yes?
Thanks as always.
You can apply the low pulse offset adder separately. When applied all tables for fueling comes from patch, so that is the only ones you need to adjust. I think I added some math conversions in the description part. Maybe some fine tuning of the flow rate will be needed at the end.Quote:

So the Injector Offset Adder is the only table in $EE that I'd need to worry about? Sweet!
The injectors aren't stock GM, but they do have really awesome data. I got them from FIC, so they have really great data tables. The one I was sent was already configured for 43.5 PSI and E10 fuel, even, which was nice. And thanks to that spreadsheet from dzidaV8 it should be pretty easy to translate their data into your patch tables. Thanks again!
Okay, so after messing with this, I just want to make absolutely sure I'm doing it right. I found this discussion by 84Elky over on ThirdGen regarding the calculation for voltage offset, noting that GM apparently applies the value twice. Here: https://www.thirdgen.org/forums/diy-...ml#post6346200
I found that for my injector data, I have some times as high as 5496.246 microseconds in my datasheets, but the LS Inj patch only allows a maximum of 3891 (FF). Is this a limitation of the calculation, or should I be dividing all of my numbers by 2 before putting them in?
you'd only divide by two if your xdf's conversion to usec was incorrectQuote:

if your injector's supply voltage goes outside that range it's because something is broken, so having incorrect values in those areas is the least of your concerns, you will be 'limping' anyway.
pretty common for datasheets to have crazy values outside of operating range
3891 (FF) is 8 bit limitation, so that is the max you put for these cells. I guess they are in very unusual conditions so you don`t have to worry about it.
I suggest you apply the
low pulse injector extend hack
patch too
and fill the
low pulse inj width correction
table
It gives better resolution for low pulse conditions.
One other limitations is there is no negative values possible, so if you have negative values you can set that cells to 0.
The low pulse offset adder is done by eside cpu, but the main offset is handled by tpu so nobody knows how it is done.
Since I have already run the patch for long enough time, the provided sample tables have been tested well enough and you can use them for reference.
