how-to: ECU-based direct boost control

[Tokyokiwi]

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?

88580014 should be the same as 88580015. i got a the tables for that shoot me a PM with ur email addy.

$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

Q. If WGDC = 60% previously yielded 27 psi boost, how come after all error correction has been removed (i.e. 68% back to base 60%) is your boost level still above your target boost (i.e. 28 psi), and not at 27 psi as it was previously at 60% WGDC?

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?
