Anyone know the map names or acronyms for correcting the ignition angle based upon intake air temperature? -Thanks

^ that map is for coolant temp not iat... at least that's how i read it. I think there is only an iat correction for load, but i could be wrong. kftarx

From what I know off hand, you can control specified load, target lambda, boost limit, and target boost pressure based on intake air temperature. I don't know of any maps that allow you to adjust ignition timing based on intake air temperature.

Maybe you could tell those maps IDS? Especially boost limit based on IAT?

KFLDHBN
The map name translation is wrong as it makes you think it is some altitude correction map. It is not. Axis are RPM and IAT in celsius. Values are max compression ratio.
At least that's what I deducted from it and my massaging of the table confirms.

Isn't this just a component protection map? Basically if that pressure ratio is actually exceeded, the system goes into soft limp mode. Pretty inconvenient for tuners if you ask me.

It is. It is multiplied by ambient. Altitude increases and ambient pressure decreases. To control load based on IAT you should use KFTARX. Isn't this just a component protection map?

No, it is simply multiplied by ambient then converted to load. If this is lower than the other max load values then rlmax_w will follow it.

This is correct. The axis are nmot and tans. ^ that map is for coolant temp not iat... at least that's how i read it. I think there is only an iat correction for load, but i could be wrong. kftarx
That is KFZWWLRL and it is the actual warm up map.

I see. So at best KFLDHBN will limit load based on ambient pressure.

It is. It is multiplied by ambient. Altitude increases and ambient pressure decreases. To control load based on IAT you should use KFTARX. It's both not correct. The translation is right because the actual sense of KFLDHBN is to protect the turbocharger from overspinning on higher altitudes. The axis are IAT and N. Isn't this just a component protection map? Basically if that pressure ratio is actually exceeded, the system goes into soft limp mode. Pretty inconvenient for tuners if you ask me.
No, it is simply multiplied by ambient then converted to load. If this is lower than the other max load values then rlmax_w will follow it. It is a component protection map but more similar to stuff like KFLBTS.

Bob is right as usual. I spend hours translating these modules. Do you guys not read them? "...the maximum cylinder charge is limited by an external pressure dependency to avoid overloading the turbocharger at high altitudes"http://www.nefariousmotorsports.com/wiki/index.php/LDRLMX_3.100_(Calculation_of_LDR_Maximum_Cylinder_Charge_rlmax) TTQS

This always baffled me... ME7 calculates both req load -> req boost AND back calculates max pressure (from max pr) to load.. Can somebody post a simple equation for both? I've been trying to decipher the FR, but what i come up with has yet to match my logs

I'm not excatly sure what you mean, but if it's regarding rlmax then have a look at LDRLMX in the FR.

Sorry to bump this from the dead, but was the OP's question ever answered? If it was I missed it. Just curious to know the acronym. Thanks!
