Higher than 319 boost limit

I would like to use higher than 319 in my boost limit table. How hard would it be to come up with a patch or add to an already popular patch? (hint: the popular one has a 5 in it's name). I do not write code so please explain this to me in layman's terms.

Thanks

set it to 319 thru out the whole rpm (thats the max it will go up to). Then set your Timer to 50000, that will basically disable it.

I have a solution, you will be able to double your max loads, I will post up for 88590015 when I get to work!

ok for 88590015 add

Code:

<table name="Boost Limit Dbl" category="Turbo" address="15cc4" type="1D" scaling="Hex16"/>

Now change the "Boost Limit Dbl" table from 0x6DDD to 0x4D00.

Also change your "LoadBoost" scaling from

Code:

<scaling name="LoadBoost" units="%" toexpr="x*5/4" frexpr="x*4/5" format="%.0f" min="0" max="319" inc="1" storagetype="uint8" endian="big"/>

Code:

<scaling name="LoadBoost" units="%" toexpr="x*10/4" frexpr="x*4/10" format="%.0f" min="0" max="638" inc="1" storagetype="uint8" endian="big"/>

Note the toexpr, frexpr and max changes.

Let me know how/if that works.

Cheers
D.

Just to be sure everyone understands the ABOVE mod is UNTESTED!

I guess do the mod and set your boost limit load to something like 120 and then do a low speed/low load logg to make sure you hit the limit like normal...

I cant set it higher than 102 for some reason? Do I need to enter it as a hex value or something now?

my bad scaling should be:

Code:

<scaling name="LoadBoost" units="%" toexpr="x*10/4" frexpr="x*4/10" format="%.0f" min="0" max="319" inc="1" storagetype="uint8" endian="big"/>

obviously for 1.30 and below it needs to be endian=little

HMMM could this be used to reduce the maximum timing retard limit???
at addresses 173f for 90550001 and 133f for rom 88570008
at the moment when its set to 255 the max limit is -10
