I believe the warm-up tables correspond to a couple tables possibly mentioned in another thread on 96530006 by mattjin?
https://www.evolutionm.net/forums/ec...ml#post6457282
Start Up MAF Comp 1 Address = 3712
Engine temperature =69d8
Start Up MAF Comp 2 address = 3722
Engine temperature =69d8
He hypothesized they were decay timers though and only acted during the short post start period?
I definitely like what you are proposing though, just wanted to toss that out there and maybe get a unanimous understanding of these tables.

). For the warmup MAF scaling, its based 100% on reading the disassem. If you want to log the warmup MAF scaling value, its at FFFF8ABA in the 96530006. Its a one-byte value, so only the low byte needs to be logged.If the logged values during warmup are a bit different than what's in the table, remember there is another trim table that I have not posted. If you want to see it for 96530006, the first axis at 0x66F2 is 14 elements long and is 2-byte load. The second axis at 0x7ADC is 8 elements long and is 2-byte RPM. The table data itself is at 0x6071.

Sorry, I should have explicitly mentioned that they were two-byte (I just listed the first byte of the two). I'll edit my post to reflect that.
With DMA logging, the bandwidth issue with two-byte values really isn't that big of a deal. But yeah, if we expect people to log this stuff regularly, multi-byte values may end up being a pain. I'm guessing from the scalings that we won't be able to get away with just logging the low byte?

Mrfred, that is great news. I figured you had come to that conclusion from dissassembly, I just wanted to eliminate the change of them being timers, as suggested previously.

Shadow1, please show me exactly the tables you are talking about. Those two tables I listed ARE NOT in that post. That is why I put them up.
Thanks for a sainty check though. Maybe I am just flat out blind and ctrl+F just isn't working on that post.

My mistake. I had to enter those tables myself for 96530006:
<table name="MAF Comp vs Coolant Temp #1" category="Fuel" address="3722" type="2D" level="1" scaling="uint8">
<table name="Coolant Temp" address="69d8" type="Y Axis" elements="9" scaling="Temp"/>
</table>
<table name="MAF Comp vs Coolant Temp #2" category="Fuel" address="3712" type="2D" level="1" scaling="uint8">
<table name="Coolant Temp" address="69d8" type="Y Axis" elements="9" scaling="Temp"/>
</table>
<table name="MAF Comp vs Coolant Temp #1" category="Fuel" address="3722" type="2D" level="1" scaling="uint8">

I belive that I am. I don't have laptop at work to cross check, did you change anything in the Decel tables since first post? If not then I have exactly what you have. Running 88590715 rom (recompile for MAF). Not sure that matters. The tables all appear correctly in ECU flash, just can not edit the values.

this patch looks pretty cool, 
and am trying to gove it a shot, but Im having issues w/ getting the new patch to show up in evoscan... (always had issues getting new data items to show up)... I got the patch for ecuflash up and dl'ed the rom, copy/pasted over the 3 maps, but when I go to patch up evoscan (2.5) it will not show up, nothing will. I had to dl 2.6beta just to get the rpm_speed_ratio logging, but w/ this version, I cant seem to get it to connect to my wb, so I stuck w/ 2.5.
I have tried placing it in different places, top, middle bottom... nada..
I tried editing in the rpm_speed_ratio map manually into 2.5, and it doesnt log correctly... IDK set it up, just as the .xml has it...
any ideas?
