Attn MrFred

Would you be interested in trying to make this work on a Evo X SST ?

I would happily donate whatever you think fair to have this on my car

Thanks

Could somebody please help me to identify the xml definition for ECU based direct boost control for 88840017 or (16) or maybe to 88580015?

$10 Paypal to the person that figures out my problem. Error correction can add duty cycle to the base duty cycle and it can remove added duty cycle if needed. Although it can't pull duty cycle below the base setting.

Example: boost is set to 28 wgdc is set to 60%, boost hits 27 and wgdcc adds 8% boost hits 29, new wgdc is 68%. At this point wgdcc kicks in to lower boost but it is only capable of removing what was added, once 8% has been removed downward correction stops even if it is still above the target boost.

Also: "Total max upward duty cycle vs tps" is set to zero accross the board, and "total max downward correction" is set to -50

This is a somewhat tangential question to the question you asked since downward correction of WGDC from base WGDC is still desirable in case base WGDC is set too high for target boost to begin with.

FCA bit 10 can enable or disable MAP feature on a car or not?

question:

Should i remove the load based settings seeing that i am using direct boost? Does it matter? The ecu wont get confused with having both there?

Also, on my 94170015 rom you have only two addresses for reference "44f8" and "453a" the two in between... "450e" and "4524" don't get used?

<table name="Baseline Boost #1" address="44f8">
<table name="RPM" address="6982"/>
</table>
<table name="Baseline Boost #2" address="450e">
<table name="RPM" address="6982"/>
</table>
<table name="Baseline Boost #3 (BCLS)" address="4524">
<table name="RPM" address="6982"/>
</table>
<table name="Baseline Boost #4" address="453a">
<table name="RPM" address="6982"/>
</table>

Thanks

Jeff

Boost adder and baseline boost.
Just to make sure I understand correctly. If I want 30 psi, then adder should be 14.7 and baseline boost = 15.3

thanks

that would get you something around 15 psi on your boost meter.

Ok. So in my case @ 30 psi and me at sea level I would 24.6 baseline and adder would be 20.1

nope, the load stuff alters itself to match your psi stuff, generally. leave it, its ok. are you using V7?

I'm not using v7. Just want it cleaner, instead of 2 sections for boost control
