SMOOTHBOOST Supercharger Active Bypass Boost Control System Manual

Supercharger Active Bypass – Boost Control System
Isaziso Esibalulekile: Please read this document thoroughly before beginning installation.
The SmoothBoost actuator must be mounted to the supercharger only after all wiring steps are complete. This ensures the unit can be properly adjusted while the vehicle is powered.
PART 1: WIRING
Iyunithi ithunyelwa ngesixhumi samaphini angu-3 kokokufaka kwe-boost control. I-jumper wire ephinki ifakwe phakathi kwamaphinikhodi A no-B. Ungasikhiphi lesi sikhulu kuze kuqedwe zonke izinyathelo zezintambo kanye nokulungiswa kwe-actuator. Uma ukufakwa nokulungiswa sekuqediwe, ungakhetha enye yezinketho ezilandelayo zokulawula i-boost:
- I-Boost Control Lockout Plug
- Thuthukisa Knob
- SB-DCA Module (enables boost control via ECU PWM [-] output)
Ukuxhumana Okudingekayo
- Intambo EBOMVU – Amandla
Xhumeka kumthombo we-12V oshintshiwe osebenzayo uma ukhiye usendaweni yokuqala/ukusebenzisa. Inketho ethembekile, uma ikhona, indawo yamandla kagesi/isilayidi sikagwayi. Qinisekisa ukuthi umthombo okhethiwe unikeza kuphela i-12V ngokhiye ekuqaliseni/kuqaliseni.- Isistimu ye-SmoothBoost kufanele ivikelwe kahle nge-5-10 amp fuse
- Intambo EMNYAMA: Ground
Connect to a clean ground point, ideally the PCM ground location or directly to the battery to avoid electrical noise. - PURPLE wire: Throttle Signal
Requires an Analog 0-5volt signal
Isexwayiso Esibalulekile: Never handle this wire while the unit is powered on or while the 14-pin connector is plugged into the controller. Leave the main connector unplugged until all other wiring is complete. NEVER apply more than 5 volts
Drive-by-Wire cars: Connect to the accelerator pedal position sensor (APPS) 0-5V signal
Amanye amakhithi ahamba ngalolu xhumo njengepulaki nokudlala okwenza lesi sigaba esilandelayo singasebenzi.
- Most throttle bodies can be tapped for this signal instead, but some systems such as newer GM can not
With key on, check with a multimeter Pedal released: 1.5V or less. Wide open throttle (WOT): -3.8V +
Amaphuzu ajwayelekile yilawa:
- I-Mopar/Ford: Iphinikhodi 2 ye-APPS
- GM: Pin 5 (Pin E) of APPS/Pin2 on 2022+ Truck, SUV’s
For Drive by Cable: Connect to the TPS sensor 0-5volt feedback output
Ukuxhumana Ongakukhetha
Lezi zintambo zisebenza isikhashana uma zinikezwe isignali yaphansi.
Ungayisebenzisi ivolumutage to these wires-doing so will cause internal damage.
- Blue Wire-Boost Cut
Ivula i-valve yokudlula, isuse i-boost. Angaqaliswa amadivayisi afana namageji e-failsafe AFR, amasistimu eleveli ephansi yamanzi/methanol, noma ama-ECU emakethe angemuva. - Gray Wire-Calibration Mode
Grounds during actuator calibration for valve-closed/boost position setup. - Tan Wire-Scramble Mode
Iphoqa ukusebenza okugcwele kwe-boost, okulingana nokulungiselelwa kwe-boost knob enkulu noma ukufakwa kwepulaki ye-bypass.
Part 2: Actuator Installation
When wiring is done, plug in the actuator and power up the system. Play with the throttle pedal a bit to get a feel for how it moves before bolting it to the supercharger.
Isici Sokuphepha
If the actuator can’t hit its target, the motor can overheat. To prevent that, the unit has a built-in safety: if it pulls max current for a few seconds, it shuts down. It’ll come back online after cycling power.
Izinyathelo
- Take pictures or notes of the stock vacuum actuator’s open/closed angles. Remove it. Install the supplied 10-32. to ball socket adapter on the bypass valve lever.
- Mount the actuator to the supercharger using the original bolts and the included washers. Leave the bolts a turn loose for now. Snap the actuator rod onto the ball socket. Then move on to adjustment.
Inqubo Yokulungisa
SmoothBoast works like a drive-by-wire throttle for your bypass valve. It needs to go from the idle/cruise position (retracted) to the WOT/full boost position (extended)
- With the unit powered off, pull the actuator rod out by hand to see where the boost/valve-closed position is.
- To extend the actuator for setup, either: Ground the Gray calibration wire OR Have a helper holt the throttle at WOT
- Slide the actuator toward the bypass shaft until the butterfly valve is fully closed.
- Tighten the mounting bolts. Use washers keep the bracket from shifting as you tighten.
- Disconnect the calibration wire and power off the unit
- Move the linkage by hand through its full range make sure it doesn’t bind or hit anything.
Qaphela: The bypass valve should rotate about 80% if it goes further, it may start to close back down in opposite direction.
Adjusting Travel
- The unit ships with minimum travel
- Ukulungisa: loosen the 5.5mm bolt under the cap and slide the pushrod jout more travel, inless).
- Or, remove the cap with a #0 Phillips and adjust with a 5.5mm socket.
- Any time you change travel, repeat the adjustment procedure.
Ukuhlola
Uma ukhiye uvuliwe/injini icishiwe, cindezela i-throttle:
- idle actuator retracted
- WOT-actuator extends smoothly
- The bracket should stay solid if it flexes, something is binding, and the unit may trip protection mode
Cap unased vacuum ports and secure wires/hoses away from heat and moving parts
Keep an eye on your AFRs-tuning is highly recommended since the engine will see new load areas
Ukuxazulula inkinga
- I-CEL noma i-Limp Mode The controller must power up with the engine/PCM. Check power, ground, and actuator function (key on/engine off testi.
- Protection Mode-if the actuator shuts down, it’s usually from binding or mis adjustment. Redo the adjustment procedure.
To clarify how a bypass system works:
- Extended actuator bypass closed → boost on
- Retracted actuator bypass open bypass airflow for cruising/efficiency
