I would definitely try and see if someone can get the LOAD based definitons for this rom. I am NOT a fan of PSI based boost control. I tune for a load curve, not a PSI. The same PSI will have different 'loads' as the climate changes. NOt a HUGE amount, but enough to be less consistent than my O.C.D. allows lol.

 

For 96260009:

<table name="Max Total Upward WGDC Correction vs TPS" address="40ee">
<table name="TPS" address="5eb0"/>
</table>

In evo7base:

<table name="Max Total Upward WGDC Correction vs TPS" category="Turbo Boost Single Solenoid" type="2D" scaling="OffsetWGDC">
<table name="TPS" type="Y Axis" elements="9" scaling="ThrottlePercentage"/>
</table>


As for the load values - who should I ask? A couple of obvious names come to mind, but that'd just be another thing to add to their never-ending lists I bet!

 

Ask MrFred. It may come with a donation but it's worth it.

Also, rename that table to 'MAX Total Upward EGDC Correction' since its labeled wrong.

Cool, I'm happy to donate. I'll get in touch.

I bet that there's many things that need relabelling in the 96260009 xml (as with all other xmls). One step closer now thanks! I know for one that the "Boost Enhancement Enrich/Enlean (Anti-lag) Map" has the same address as the "Low Coolant Temp Timing Trim Map" in this xml. A problem for another day

 

Trying not to stray from the topic here, but I think that I figured out how to do the improved load-based boost control for 96260009, but I'll wait for MrFred's response. There are at least a couple extra things to log that I don't know. Attached is my log from last night with the load control improved (I think!).

First time in a while that I haven't gotten knock, too. Was getting crazy knock on a hot day a couple of days ago, which could have been explained by the car over-boosting to reach BDEL levels.

...Back on topic - any luck on the boost when cold nocabiwiksmx?

 

I have the load-based boost control improvements for 96260009 (which work for the standard V7 rom also):

<table name="Variable for Boost Control" category="Turbo" address="1e972" type="1D" level="1" scaling="Hex16"/>

<table name="Load Error RAM Addr" category="Turbo" address="1e966" type="1D" level="1" scaling="Hex16"/>

<table name="Load Error RAM Addr in Load Error Table" category="Turbo" address="5e80" type="1D" level="1" scaling="Hex16"/>

<table name="WGDC Correction Interval #1 (High Gear Range)" category="Turbo" address="1a54" type="1D" level="1" scaling="uint16"/>

<table name="WGDC Correction Interval #2 (Low Gear Range)" category="Turbo" address="1a56" type="1D" level="1" scaling="uint16"/>

<table name="MUT8A Use for Load Error" category="MUT" address="34752" type="1D" level="1" scaling="Hex16"/>

<table name="MUT8B Use for WGDC Correction" category="MUT" address="34756" type="1D" level="1" scaling="Hex16"/>

I paraphrased MrFred from this thread, comfirmed with him that it's right and tested it myself.

 

Well done sir

Yep, I no longer overboost when cold with HD's xml which let me change a few things. The fix was on the WGDC vs Coolant Temp table I changed the 0's to 30 which translated to 1bar boost when cold. When it was 0 it overboosted.

Thanks guys

 

Sorry to bring up a slightly old topic, but this looks like this is the same exact problem I have. I am on ROM 96532706 and boost would spike just before the engine was fully warmed up.

However, I am a headgasket too late since I did not look into this issue and forgot about it after not driving the car for about a month.

The only table that was ultimately the culprit for nocabiwiksmx was the "Max WGDC vs Coolant Temp" table correct (although he also had a bad xml file)?

 

Hey GOOBR, was just in touch with the OP today, and he's traded his 8 for an RX8! But anyway, yeah just try some low (but non-zero) numbers in the coolant table and you should be good to go.
