[s-cars] Pinging w/MTM 1+

[TM]

Bob-
It was my understanding that MTM 1+ was designed for 98 RON fuel,
not 95. That's the problem- 98 is pretty high and we don't get really
good fuel everywhere. Too bad, I'd love to have affordable 100 octane
fuel at the pumps.

Am I just lucky?  I have had no problem with pinging using the MTM 1+
chips 
while running mostly 93 octane fuel in my '95 urS6.  It did get a rare
fill 
up with 94 but that was rare.

BTW, the RON and MON numbers are simply rating numbers 93 (RON + MOM)/2
is 
the very same fuel as 95 RON.  RON rating and MON ratings on the very
same 
fuel are always different numbers with the RON rating always a higher 
numeric value than the MON rating number.  This means that the RON
number 
for any specific fuel will always be a higher number than the (R+M)/2 
rating FOR THE SAME FUEL.  95 RON and 93 (RON + MON)/2 are equivalent.
