I wouldnt suggest doing it without a dyno. If you have an EGT guage you can use the temps to tune. If your temps are high you need to richen up, if they are low you can lean the mixture a bit. I best way is the dyno though.supraron said:ok, I know I am running rich, cause I can smell the fumes, how can I tune the fule controller without using a dyno?
or can I not.. i'm looking at the apex afc
Try to tune to 11.25:1 AF between 4000RPM and redline. Don't touch the AF below 4000RPM.Spool said:Get on a Dyno with a shop that has a Wideband O2....if they have the wideband O2, then they should know how to tune. Ask if they know about Supras...also post about a tuner in your area.
