#78378, "Tunning guru's (question)"


          

Ok, im running basically a hahn kit with FMIC and 30LB injectors with in tank walbo fuel pump and SFMU. Im tunning for 7PSI right now on stock internals. Also stock exhaust minus test pipe and 2.5" downpipe. Im also using a data logger to try to get some values but I dont have a Wideband yet so I using some of the value from my 02.

In 4th gear I took it up to about to about 5800RPM and found that my fuel starts out at .98 (a little rich) and then tapers down to about .92 (lean) by 5800 RPM. My timming for the most part starts at about 16 advance and moves up toward 19 and then drops a little at high RPM (possible knock due to lack of fuel?)

First off, what do you guys think of these numbers and second which SFMU adjustment should I use to flaten out the downward fuel slope at high RPM.

Also, at 5800 in 4th I was only at about 1400 DEG EGT. Maybe just above. It been pretty cool out. Also my LTFT and STFT stay together real close to 0.
