What afr' do gtr r33 nomally run @1 bar on stock ecu?
Checked mine with my lm-2 and am getting low 12's 4-6000 rpm range and 11.6/5 between 6-8000 rpm.
I thought gtr normally run rich at 1 bar. I think i might have a remapped ecu if they are supposed to run rich but there are no stickers on the ecu and car was virtually stock when i bought it.
Would u guys consider low to mid 12's as lean if you got no det and running on 99 oct v-power?
