[s-cars] Pinging w/MTM 1+

[Lewis, Gary M]

Trevor,
Data point.  With the VMAP-D set at 2.9 bar (instead of 3.0 bar) and 26 psi software, RS2 EM, RS2 Injectors, RS2 MAF, and RS2 Turbo (well, sort of), my car DOESN'T ping on 91 octane and plus 100 degree temps.

HTH,

Gary Lewis

1995.5 S6 Avant, Green/Ecru, RS2 MAF, RS2 Exhaust Manifold, RS2 Injectors, Custom Turbo (K26 Turbine, Factory K26 Cold side (Audi Works '999' P/N) with 50mm intake and custom Innovative Turbo compressor wheel), TurboXS Type 25 Bypass Valve, Bilsteins, Eibachs, Big Reds, Spec II Clutch.
