F5272 Rail limiter RPM / Q fuel
usually there are two limiters on the rail first is
RPM / Temp FUEL
and other RPM / Q. Fuel (mm3/cyc)

Draw your own conclusions ;)

And so is very dangerous for turbo boost! :?
But this mod is made from professional tuner :shock:

Its not the boost limiter its the atmospheric torque limiter ;)

Amended all values to be signed by default.
Negative values now show properly in all tables/functions/constant.

Perhaps that why the 1st 4 columns appear to be Temp C and the last 4 columns IQ ?
Maybe they are all fuel temp ?
1431 = -130 C
2986 = 25.5 C
3653 = 92.2 C

Don't know.... need convincing.

Modding this I can have all torque request whitout limits?

How it affects the atmosphere pressure on the torque?

Rewrote code to allow for categorys for all software versions.
Added new category list.
Amended all tables/functions/constants with new suitable categorys.

Inverted EGR duty and IMRC Duty tables to match datalogs.

...and we're done! For now at least.

Atmospheric pressure allows a higher density of air.
So you can get more fuel for the same lambda.
Its also a good way to cut boost if Atmospheric pressure is lower.
Boost depends on IQ vs rpm....lower the IQ you lower the boost.

Attempted Recreated Damos of the Boost section.

Hello. Can you tell me how egr close in this ecu in honda? In 1hyst egr i must write 65436, in 2 hyst 65336, in 3hyst 65436, in 4hyst 65336?
And what is engine duty table? It is something like dw? It is request iq vs rpm vs pedal?
Or.this is.limiter iq vs rpm vs pedal?

You sir, are a legend!

I am sure you are probably long gone, but this XDF has been really useful! I'm trying to tweak a map on an Accord i-CTDI.

Thanks very much!
