need help adjusting the injector lag/ transition
ive been having trouble getting my tune down. i think it might be my injector lag and transition. all ive changed is the injector size.
injector specs primary high imp Static Flow Rate: 80lb/hr = 875 cc/min Dynamic Flow Rate : 18.6 mg/pulse 2.5ms PW, 20 ms Period secondary low imp Coil Resistance: 4.5 Ohms / Low Impedance Static Flow Rate @ 43.5PSI ( 300kPa ) w/Gas: 1600 cc/min = 152 lb/hr ive found these but it doesnt make since to me Injector____Denso________Denso (w/ Peak & Hold Driver) Flow CC/min__550________550 Flow LB/Hr____52_________52 Ohm__________2__________2 10v_________1.24_______0.66 11v_________1.04_______0.58 12v_________0.87_______0.50 13v_________0.75_______0.41 14v_________0.64_______0.34 15v_________0.55_______0.27 yea, you'll want to put in the lag timings for each voltage. Then you want the "gross" lag to be zeroed out. The X's will be whatever your fuel map is set at. mine are at 90, but that was to get in the ballpark, and then the map was tuned around that. So you'd have something like: Front Primary_______X_______0.0 Front Secondary_____________0.0 Rear Primary _______X_______0.0 Rear Secondary_____________0.0 The Q's would be your injector size at whatever fuel pressure you run. I run 725 and 2000's, at 43.5psi base pressure, so: Q Primary_____715 Q Secondary___2225 You'd obviously want to put in the 1015 for the primary, if you are running 43.5psi On the transition, this will vary based on what works for your car. My car seems to like to transition at 30% and .900ms Then, like i said, the tables to the right of that you pull directly from the charts fendamonkey posted. So if you are running 43.5 base fuel pressure, you'd input these values: _________Primary_____Secondary 16v_______.805________.375 14v_______.990________.495 12v_______1.240_______.680 10v_______1.675_______.950 8v________2.600_______1.455 6v_____(interpolate)_____2.840 http://s6.postimg.org/3mb7osgld/setting_1.png http://s6.postimg.org/pwz2ordvl/setting_2.png http://s6.postimg.org/akaqgzpc1/setting_3.png http://s6.postimg.org/3v470z401/setting_4.png http://s6.postimg.org/5bkawuwap/setting_5.png |
The 800's should not be at 100 %, they should be at 68.75%
You have a DL why do you have your fan temps set so high? |
oh ok i will make the changes. i dont move the temps since i have a fan controller in place
|
The PFC does a fantastic job controlling the fans, no need for another independent controller.
