accelEnrichGauge not understood

Post by Philip Lochner »

Say I have a pw of 3ms at a given engine operating point and I program AE to give an additional 2ms of fuel, surely this translates to 66%.

My "problem" is that my accelEnrichguage typically shows 1 - 3% and rarely goes above 6% when I would expect figures of up to 200% or more with values of 2, 4, 6, 8 in my AE bins.

Is there something I'm not understanding?[/code]
Kind regards

That gauge is mis-labeled in all versions of MS and is realy added ms of AE except the late versions of Extra. In Extra the rauge would read 200% for twice as much "delivered fuel" The gauge is called "AE driven Fuel Pct" If I remember, this gauge assumes 1ms injector opening time.

in megatune.ini

Code: Select all

  accDecEnrich     = 	{ accelEnrich + (tpsden ? tpsfuelcut : 100)      }, "%"
So when you have decel, it is % corection. But in Accell it is actualy ms x .1

So 3% is 0.3 ms AE.
I do recall slightly different behavior in various versions of msns-extra, but that was about a year ago for me.

I usually just change this to show only the AE pulse and rescale the gauge.
(well, except that my decel is also in ms... thats another story)
