I been noticing that on a 2011 GSR there is a TPS limit that is hitting in 1st and 2nd gear. I need to check if the RAX patch is not messing with the 2011's ROM. I will have some results after Xmas or New Years.

 

Let me know if there's anything you need. I've gone back and checked the two "2011 GSR" patches again, and can't find anything amiss. Some things that may help...

- Each patch can be applied to the ROM independently. Might be useful if you're investigating a potential side-effect, and can reliably reproduce the apparent "symptom". Apply just the Baro patch and test, then apply just the IAT patch and test.

- Source code is available on request (if you're into reading that sort of thing).


Cheers,

It is a odd issue.

TPS ceiling is applied to gears 1-3 so far I noticed, higher load gears do not get this side effect

If there is 1-3 gear run.

1st Gear is getting a 50-60% TPS only when pedal is @ 100%
2nd Gear is getting a 70-80% TPS only when pedal is @ 100%
3rd Gear I seen 85-96% TPS range when pedal is @ 100%

I know it is ceiling because the TPS maxes out and stays at the ceiling. ECU is limiting it.

I will post a log when I get home. It is a strange issue. Never seen it on any other car than a 2011. All airflow/torque limit, TPS tables, Ramp Rate tables are maxed @ 100%. Stock ROM only additions are the RAX PATCH V2. I will take off the patch when retuning and see what can be causing it.

Plus it does not happen consistently. It seems like there is a condition that set and met and it trips this ceiling. Once it hits set target boost it limits TPS. Dunno just a idea. Won't know till the car comes for a retune sometime after the holidays.

 

Just an update...

This odd "TPS backoff" is still occurring on the tune in question, even after RAX Patch was removed... so not related to the RAX stuff, it seems.


As to what it is related to...

Here's a nice log graph pic... of Crimson Red testing out the Atmospheric Boost Baro Compensation patch for JDM ROM. He found a convenient mountain, and drove over it.



This logging item is the dynamic variable that RAX Patch feeds in to the boost target code... replacing the original "Atmospheric Boost" constant. PSI-based boost targets will therefore be the same "gauge" pressure at any altitude.

Nice pic!

I suggest getting a stock 2011 rom and copy and paste the old tune's values into the new rom.

2011's don't normally have a ceiling.

 

RAX Patch is already built in to razorlab's v27 Base Maps, which will be released "real soon now".

For those who don't wish to start from these Base Maps, I've now released Ralliart Lancer versions of RAX Patch... able to be applied independently.

Download link is now up in first post.

Enjoy...

I'm having some trouble implementing the patch using the documentation provided.

The rom I am working with is based off 52680022, which inherits 52680015, which of course inherits evo10base. The problem I am having is if I insert the <include> line into 52680015.xml I am unable to see the evo10base items. Depending which include line is on top I can either see the RAX items, or the evo10base items, but not both.

I resorted to putting the <include> line for the RAX patch in the evo10base.xml and am able to see all items, including the patch. But this means that any Evo 10 romID I open will use the RAX patch for 52680015.

Is there a way to include multiple xml files inside a definition? Or is the way I have it setup now correct?

 

Get rid of the include. Copy the .xml text for the RAX Patch just like you would any other definition, and put it in your 52680022 .xml.

 

That will be a problem if you are using an "include" that drills down to a generic base xml (eg. evo10base). At present, EcuFlash doesn't seem able to use multiple "include" statements.

As most people I'd talked to seemed to use Golden's XML definition files, I wrote my doco and release stuff so as to use those as a base.


As kozmic said, you can simply grab the entire RAX Patch XML text and paste it into an appropriate "existing" definition file. I'd suggest dropping it all right before the final </rom> line.

I added the RAX Patch to TephraX V1 For 55580006(55580106) on my 2010 SE. Everything is working as planned! So 55580005-5558006 are tested/ good to go. Can't wait for V2! Sending a donation to you and tephra shortly!

 

Brilliant - thanks for the update.

Atmospheric Boost Baro Compensation for 53050109?

 

Oh yeah, I've got to update all those ROMs to a new version. Here's a starter for you, though...

RAX Patch EVO X SST v1r08 53050009

So far, that's the only ROM I've done. Once I've done all of them, I'll update the first post with upload links...
