Re: VE tables

Yes, the VE table is used to determine fuel in both cases.

CL calculations are the same as OL, except CL also adds or removes fuel based on the difference between the targeted and actual Air fuel ratio.

Re: Desired torque implications on tuning process

How you do for use trim ? please To use the fuel trims, you will need to leave Closed Loop enabled. Simply hold the engine at the RPM and Load level you're tuning, and let the fuel trims balance themselves out. Once they've stabilised, update the VE table accordingly. eg. Long term: 2% Short term p...

Re: unable to load user supplied tune

I'm not sure if you can open S1 tunes when Versatuner knows you have an S2. I'd assume not, as I believe they have different tables. I've updated the first post on my Zen's Cable Throttle tune thread to contain the tables in a bunch of different file formats so you don't need to rely on the screensh...

Re: Zen's Cable Throttle tune

That's right, they're there for reference, as the provided tune will get manipulated by Versatuner if your calibration is different

Re: Zen's Cable Throttle tune

I do experience that a little when it's cold with high idle, I don't believe we can control the conditions it uses to determine whether to use idle logic or driving logic. It'd be nice to be able to configure the idle vacuum requirements but not possible from the looks of things

Re: Zen's Cable Throttle tune

did you got any problem on low load running and car "jumping" ? Not entirely sure what you mean by jumping, unless you mean first gear bucking which I haven't noticed any difference. If there are issues in that regard, they should be solvable my making low-throttle even less sensitive in ...

Re: Desired torque implications on tuning process

After some further experimentation, it looks like it works as expected! I'm super happy with the outcome, I think this may change the way we tune RX8s from now on! I know I'd never go back :bouncinggrins

See my new thread with the example tune for more information!

Zen's Cable Throttle tune

Hi all Overview I've been doing some experimentation with the "Desired Torque" table and I've managed to entirely remove it from the DBW calculations. This means the logic behind the intake butterfly valve is now: Physical Accelerator Pedal position -> Throttle Duty Cycle table (sets the t...
