Hi if I have X-Tau enabled under Fuel setup / General Settings/ X-Tau enabled... does this override the normal acceleration enrich config, (in otherwords disable the accel enrich ) Or do I have to turn that off elsewhere, Or.. do both run simultaneously.

By just enabling X-Tau my car really responded nicely ( my map is well tuned ) I am just trying to understand what's going on there.

Thanks in Advance

I believe it overrides normal AE.

Darren, Matt;

The X-Tau doesn't override the normal accel (TPSdot and MAPdot).

In the manual it says,

As you dial-in the X-Tau parameters, the engine will likely become overly rich due to both normal and X-Tau enrichments being applied. You can try reducing the existing TPSdot or MAPdot based accel/decel enrichments, which do NOT go away when you specify the X-tau option and increasing the X-tau variables. (Note that you may have to increase the cold accel multiplier as you do this.)

Mea culpa. Thanks for the correction.
