GTT fuel

[WCKWGN]

try about 450km odd off 60litres in the gtt, yeah they where meant to be be tuned on 100 from the factory so the closet to this is what should be run where possible imo

from my understanding if you run a lesser octane than the 100 octane it is mapped for the ecu will pick this up and retard the igintion to prevent detention. obviously going as low as 91 is testing the limits the fuel map toyota prob set on the ecu

running 98octane and getting as close as you can to the factory fuel map you hopefully will make gains in effienency in either power or fuel per km's used. or at least peace of mind


alternatively install a fuel/air meter and at least have a general idea of the mix on the exhaust side of the turbo and when you start winding the boost you can see if your rich or lean.

this is my pillar mount on the gtt

How hard is it to wire up a air / fuel meter?

m8 did it prob 2 / 3 hours all wired up for both gauges

piss easy
tap into one wire on the ecu and power it up
however they are just dico lights unless you get a wideband O2 sensor
