OFT - Example alternate maps for AT, 98RON, E85, MAF Scales

[Wayno]

Updated first post. Major improvement to AT drive-ability.

[KoolBRZ]

@Wayno, I admire your work and wish I could use any it, but I have a ZA1JA00D ROM and I can't find any xml's which are compatible with OFT's ZA1JA00D ROM's. I know they are based on the B01D ROM's, but you don't have any of those xml's, and the RR xml's don't have the engine load limiter tables. Can you suggest a source for those xml's that have the engine load limiter tables?

[Wayno]

Td-d's US definitions already have load limit tables defined.

[Wayno]

Not that I like you mate, but I've migrated the changes to a US map for you to compare to yours. if you compare the definitions that come with OFT, I think you'll find that earlier roms are all based on B000D. B01D is bespoke.

I've added definitions for the load limit tables to the U.S. definitions. Use at your own risk. Luckily those two tables have the same address at the MT roms and Td-d has a definition for B00C.

I realize the risk. That's why I'm asking you before I try doing it myself. I was able to find the cold start tables with the right addresses, but I don't remember which ROM I took them from. So, the memory addresses used in TD-D's B00C are compatible with the addresses used in an A00D OFT ROM from version 2.06? I appreciate your patience as I learn this. I've been trying to nail down a MAF scale for my Skunk2 intake ever since I installed it. Your load limiter explanation solves a mystery I've been trying to solve. Thank you.

[KoolBRZ]

I tried the xml files in your 2nd zip, B01D. Although there is an xml for my ROM, OFT_ZA1JA00D_WW, it doesn't have the definitions for "Engine Load Limiter A" or B either. Do I need to appeal to TD-D for a compatible xml file with Engine Load Limiter A and B that will work with OFT's A00D xml's, or do you have one and you just forgot to include it in the B01D zip file? I don't want to be a pest, but I've been try to scale my MAF for months, and, as you've found out, it just doesn't work on an automatic until those tables are revised.

[Td-d]

KoolBRZ - if you are running the stage two OFT maps, you are in effect running the B01D rom, so the B01D tables can just be cut and pasted into your xml definition. I've emailed you the addresses just in case.

[Td-d]

And B00D and B01D have identical addresses, incidentally.

[Td-d]

    <table name="Engine Load Limit (Maximum)" storageaddress="4AC9C" />
    <table name="Engine Load Limit B Maximum (RPM)" storageaddress="1044C4" >
            <table type="Y Axis" storageaddress="1044A0" />
    </table>
    <table name="Engine Load Limit C (Maximum) (RPM)" storageaddress="1044FC" >
            <table type="Y Axis" storageaddress="1044D8" />
    </table>

PM sent. These aren't the same as "Engine Load Limiter A", and "Engine Load Limiter B". I can only find those tables on @Wayno's modified xml's. Not even in @Wayno's modified US xml's.

[trdric]

mmm ill start chewing on this tomorrow. My 300km per tank on e85 is some kind of a pain.

[phrosty]

@Wayno do the AT-specific changes here mean I shouldn't carry over my existing MAF scale, or even use an existing baseline like Perrin's supplied one?

No?

@Wayno has just renamed them. Limit A is a single float value, and B and C are tables.

[KoolBRZ]

He's done a bit more than just rename them. Here's the lower, descriptive section from his A01I xml.

</QUOTE>
This looks totally different than your code. You can see why I would think it describes a totally different table. @Wayno's tables are in a new category, called Test, at the very bottom of the list in RR. I know now that I can just copy and paste from the B01D xml's to my OFT A00D xml's. Thank you for all your help.
