high boost on stock sequential twins - pfc charts!

[neit_jnf]

I already had the boost controller gathering dust and wanted to test the difference of closed-loop feedback operation of the controller vs the duty cycle operation of the pfc. I set target boost instead of guessing duty cycles.

I really miss the solid high-low boost switch that I had enabled in the pfc!! Click - 9psi, click - 17psi on the fly, I was using the fog lights switch for this. In the KS I have to go into mode, manually change the target boost, go back into on mode, and wait for the controller to adjust the duty cycles. Every target boost change is acompanied by a first-boost waviness or pulsing while the controller settles down to a steady boost level. No easy and quick on the fly one-button boost change. I do like the earlier spool though.

I haven't run more than 14psi in this controller though, so I don't know how it compares with the pfc's own controll at higher boost. Can't really test it until after I change the clutch. I'll decide then if I keep the controller or sell it and just use the pfc. Both the pfc and ks ebsIII use the car's stock system to control boost.

Plus I just like changing and testing things in my car! Examples, I've had 5 different downpipes: OEM JDM no pre-cat, SSAutochrome, Bonez, HKS and current one 4" SMB; 3 Midpipes: Bonez, Custom made resonated, and current one SMB; 3 Intakes: adam-c, sr motorsports, m2; 2 short shifters: b&m, re-amemiya; 3 diff size batteries: stock, optima yellow top 51r, oddesey pc680; etc etc etc
