can someone give me a baseline for timing and afr?

right now i just put it in exactly at tdc and locked it down

i tuned afr to around 11.0 to 1 on 91 octane


s4 street ported turbo motor with s5 NA rotors (9.7?) and counterweight

A/R .60 M24 B.O. Garrett hybrid 28mm wastegate boosting 10 lbs

V mounted, 3 inch DP and exhaust

safc 1 , rtek 1.8 (retards timing 1 degree every pound boosted over 9/built in fcd etc.) with 720 injectors all around

aeromotive fpr with ss fuel lines parrallel, walbro 255

plx r 500 wideband/egt/knock controller

im also getting this lean spot at light throttle at 3500.

thanks in advanced

lean spot at 3500? could be a grounding issue.

ive owned a 2.0 and did alot of research on the other rtek's. the rtek 1.X's dont retard timing enough. i would recommend manually retarding timing an additional degree per psi after 9 lbs.

as for the lean spot, like stated above, a grounding issue would be a good place to start. have u gotten the secondary stumble fix yet? if so, i would just get alittle more aggressive with the fuel to smooth out the injector transition.

i made another post in the rotary performance thread and philiptompkins said to advance it more

advance (more power) = more of a chance to blow ur **** up

retard (lose alittle power) = way safer

check the other thread...
