wich tune to use on the track ?

[Sammy11]

next saturday i'm going to the track at Zolder / Belgium.
i drive the truck on LPG (liquid gas) and Sean Roe made a tune for 100+ octane wich is LPG.

but on the track we gonna get our fuel for free , so i'm gonna ride on the track on 98 octane wich is about the same as american 93 i guess...
can i ride on this tune 3 or is it better to set tune 2 with my SCT for driving on fuel instead of liquid gas ?

the track day will not be a real race , because its a family day and people can drive along with us for 1 or 2 laps , so i'm not gonna go full trottle all the time , not gonna kill my truck for a familyday

I would put the stock back on.
It's not like you're gonna need the extra ponies (too many curves),
better be safe than sorry.:dontknow:

Get to a dyno with the fuel you are going to use and do some pulls. Make sure it isn't detonating.

This may be MORE than you want to know, but:

"In Europe 98-octane gasoline is common and in Japan even 100-octane is readily available at the pumps, but this octane nomenclature is misleading to Americans as foreign octane ratings are derived entirely differently from our own... So, like every other measurement system it seems that everyone else uses a different scale than we do, but unlike most other instances where we have had the good sense to create different units of measure in this case we all use the same name...
Japan and Europe use a system called RON or Research Octane Number to determine the octane rating of their gasoline, while stateside we use a system called AKI or Anti-Knock Index to determine gasoline's octane rating... Interestingly, to further complicate things it would seem that our own AKI system is actually derived from the average of the RON system and another more complicated system referred to as MON or Motor Octane Number... So, to recap our methodologies for measuring gasoline's octane rating are different, but share some common elements...
So, with the commonality of RON in mind a good rule of thumb is as follows, multiply the foreign RON Octane rating by 0.95 and you will have the US AKI equivalent.

( RON Octane Rating x 0.95 = AKI Octane Rating )
98 RON Octane x 0.95 = 93.1 AKI Octane (US measure)
100 RON Octane x 0.95 = 95 AKI Octane (US measure)

So, as you can see the 93 or 94 octane fuel we are all paying an arm and a leg for is actually quite comparable to the higher octane fuels found in Europe and Japan. The people whom have to worry about low octane rating are our friends out west in places like California that are subjected to substandard 91 octane.
91 AKI Octane (US measure) = 95.5 RON Octane"


got it ? :dontknow: :rock:
