DBW table converter (Outputs Throttle angle vs Pedal angle)

Hey guys, noticed it can be a pest sometimes to work out the throttle blade angle from your requested torque tables.
So quickly made this today. It's a crude conversion from your two DBW tables (Requested torque - Acc pedal and Target throttle plate - requested torque) into a simple Acc pedal to throttle plate angle.

Let me know what you thing or if you find any bugs, i'm no excel buff lol.
It's not perfect because we know the ECU will interpolate past the last used value to achieve 100% throttle, but I'm not that good lol.
If somebody want's to improve it, please feel free!

It seems to jump to the closest requested torque (As per the ABS line) But what I really want I suppose is it to interpolate.. But that's above my paygrade.

This is just the plotted requested torque tables (with some screen caps showing the changes)

I did something similar for the BRZ that does a good attempt of interpolation. Want me to post it up? The tables may be different sizes so you could always adjust for yours.

Please do!

The MY07 is different to the newer DBW if those are the only 2 tables so I just reworked your sheet. The output sheet axes can be edited and the calculations should follow through.

Just playing with the axis shows that max throttle is achieved at around 66% pedal.....

Yeah... That's significantly nicer to use than mine lol. Kudos sir.. Kudos.
At least I gave it a crack

Doesn't quite work in the real world interestingly. I'll check if it's calculating the correct throttle position for a given requested torque (And make sure the requested torque is correct for pedal position.

I did one for the BRZ. This one also allows you to set a target throttle table and it outputs the target throttle angle or requested torque tables. You'll note that on the BRZ there is a WOT Threshold table and this the requested torque output is essentially divided by this to give the input into the throttle angle table. God knows why, but it works. Just used this to tweak my throttle to good effect

In second last tab on the spreadsheet there is a converter for the throttle tables.

@Kodename47

Might you be able to add this function from your BRZ spreadsheet to the one with the larger axis you did for the MY07?
Only really want to enter a desired throttle angle vs pedal and it spits out the requested torque table required.

Can you post up what you want me to add it to and I'll see if I can :wink:

your sheert is great can you make it for any table size?

Thank you good sir

this is great! but does not have the Requested Torque Base (RPM).
