Hello,

After reading the below I have a question is rlmax derived from LDRXN in some way and is it possible to calculate\estimate the value of rlmax from LDRXN?

I've been working on mapping my BAM engine.

Thanks

Remarks: the map KFMIRL is used in the funktionsrahmen module MDFUE 8.50 with inputs of engine speed

and the target torque for the charge pathway, recalculated at lambda = 1 and zwopt (misopl1_w) to calculate

the target cylinder charge. Note that the higher values are greater than 191.0% in KFMIOP and greater than

the maximum of 185.3% in LDRXN for the BFV engine which places an upper limit on the KFMIRL output via

the variable rlmax. There is no difference between the BAM & BFV maps for calculating target charge.

KFMIRL should be used to tune part-throttle torque response.

So you didn't bother reading any of this?

Just read it again, makes more sence now I have some data & ECUxPlot.

Still not entirely sure if I should use LDRXN to cap the load or LDRXN and KFTARX or KFLDHBN.

Also as there are a lot of variables that make up rlmax, how do people usually use to adjust rlmax?

IE
If rlmax is to be incresed by 5% what amount would you increse LDRXN asumming all the other variables stay constant?

Two methods to accomplish what you want. Up to you depending on your goals.


Generally, trial and error


More or less for small changes.

You're on the right track now.

Cheers :)

Well done :)
