Try full boost, which in my case is 27psi and hold it for several seconds...

 

Same here you can do a second of 2 psi. I'm driving home now with ayc off and it ain't working . The ecu is doing something.

 

Well I turned off the AYC Brake by holding the button for 3 seconds and gave it 2 attempts to see what happened and both times the car still fell on its face. So this looks to be more involved.

I am running rom 56890010 so the question to the 2011 owner that says he can do this, which ROM version are you running? Are you using a MBC or EBC? I am using a 3-port so maybe its the boost sytem getting turned off and not the throttle plate closing...

 

How are you guys manipulating 3 pedals with only 2 feet?

 

You don't need three feet. The clutch is not involved.



I think its the throttle because the cars accelerator dies but I could be wrong. Lol

 

I have a 08 gsr that is tuned and i have been able to utilize this to hold aorund 20-22psi. Maybe if the 11's get tuned they can tune this out

 

I'll go a-digging in the ROM for this. Someone more experienced at disassembly will probably beat me to the finish line, but it'll be fun anyway.

For ROM 56890010, does someone have logging addresses for

• Accel Pedal Position
• Throttle Position Sensor
• edit - also, BWGDC - in case it's the bcs being nerfed

Also, I seem to recall a log-address find a while back of a nice address+bitflag indicating "brake pedal depressed". I'll TRY USING THE SEARCH BUTTON - wish I'd noted it down when I came across it - but if someone has a reference to that bitflag address for any X/RA ROM, that'd be another useful item.

Cheers,

Thank you Rich!

I'm using these for logging:

Accel - 23809631
Throttle - 2380873D
AWGDC - 23808B9D

I doubt it has anything to do with the boost solenoid since I did this while staying in vacuum to rule that out but then again maybe it does both...

 

thank you very much rich !

 

im running a stock turbo on my 08 tried to break boost and got nothing out of it. just burned gas and wasted some breaks lol

 

i tried this on a 2011
it does shut the throttle if you left foot brake @ 2k

 

What about higher rpms, does it still kill the throttle?

 

Yes, high rpms, low rpms, cold days, hot nights, ayc off, it just doesn't work. lol Hopefully someone will find a cure for this...

 

I've made some small progress looking at the ROM. In case anyone's interested on the story so far...

On 56890010 (2011 ROM), here are three "Brake Pedal" bitflag addresses...

0x808646 - bit #4 (00001000) means pedal down
0x80864a - bit #4 (00001000) means pedal down
0x80973b - bit #1 (01000000) means pedal down lightly, bit #0 (10000000) means pedal down harder.

There are also three other Brake Pedal bitflag addresses that seem to get copied directly from the first two... all located within a few bytes of the originals.

Cool, eh? I love bitflags.


In my 2009 RA, I can happily use the brake to hold revs steady at WOT. Mine obviously pre-dates the Toyota-style nerfing that Mitsubishi put into the later ROMs.

Consequently, I'm keeping an eye out for coding differences between my ROM a 2011 ROM. In 56890010 (2011 ROM), there is indeed new code referencing the 0x80864a Brake Pedal bitflag. If anyone is keen to check it out, it lives between address 0x1aad8 and (around) 0x1ac4c. There is no equivalent code in my RA ROM.

I haven't yet tied it to anything that mucks around with throttle closure. But these bitflags are a good lead to work from. Who knows what they will lead to?

...and they will be great to log when doing track driving and such.

Yea mine is a 2011 GSR and mine did the same thing, held 2psi then fell on its face.
