Instantly & Safely Disable Your Vehicle’s Auto Start-Stop And/Or V4 Mode
The PowerStay is a simple plug-in module that serves as an active fuel management disabler, eliminating the Auto Start-Stop and/or cylinder deactivation (V4 mode) on many newer model vehicles. Although these features are touted as fuel mileage improving features from the factory, many customers see no improvements or even experience mechanical failures due to these features. The PowerStay puts an end to these modes on your vehicle once and for all, allowing you to enjoy your vehicle as it was meant to be.Installation is Quick & Easy
With the vehicle off, plug the PowerStay in to the OBD-II diagnostic port under the driver’s side dash, then just drive your vehicle...That’s all there is to it! Re-enable either feature by first turning your vehicle off, then unplugging the PowerStay from the OBD-II diagnostic port under the driver’s side dash.IMPORTANT NOTE FOR GM VEHICLES WITH ACTIVE ONSTAR
GM OnStar cannot run the full diagnostics when the PowerStay or similar devices are plugged into the OBD-II port of the vehicle. PowerStay users that have the OnStar diagnostic app on their phone will get a message saying that some modules have faults, which is not accurate.IMPORTANT NOTE FOR VEHICLES THAT ARE NOT DRIVEN FOR EXTENDED PERIODS OF TIME
The PowerStay consumes around twenty (20) milliamps (mA) of current when the vehicle is running and goes into sleep mode when the vehicle is shut off and draws two (2) milliamps (mA) when in sleep mode. The sleep current draw is minimal compared to the vehicles own current draw, but customers should be advised to disconnect the PowerStay from the vehicle if the vehicle is in long term storage or not driven for an extended period of time.These settings allow you to customize the shift firmness and quickness to how you want it, and on properly equipped vehicles you can adjust these settings per mode (i.e. Normal mode and Sport mode). The STREET setting is slightly firmer which reduces the nosing over feeling during shifts which really improves the drivability. The SPORT setting gives firm and aggressive shifts which feel great under moderate to heavy acceleration. The PERFORMANCE setting balances firm shifts that feel great at full throttle without being harsh during normal driving. The TRACK setting maximizes the shifting performance for maximum performance during full throttle acceleration.
Trucks and SUVs will also get the TOW setting that reduces the slippage during gear changes by making the shifts a little quicker which can reduce wear and transmission fluid temperatures.
These settings allow you to customize the power delivery to how you want it, and on properly equipped vehicles you can tailor these settings per drive mode. The HYPER-MILEAGE setting is a very aggressive reduction in power delivery compared to the factory settings to help squeeze the most out of your fuel mileage. The MILEAGE setting steps power back modestly for a balance between economy and power. The STOCK setting makes no changes to the throttle response. The STREET setting greatly improves power delivery for improved drivability for everyday performance. Stepping up to the SPORT setting offers quicker throttle response that delivers power much quicker than the factory settings, and really wakes up the power. The PERFORMANCE setting offers an aggressive throttle response which balances drivability and power. The TRACK setting may take some getting used to because the power delivery is very aggressive and unleashes power that you never knew your vehicle had!
Trucks and SUVs will also get the TOW setting that increases the throttle response for additional power during take-off and maintaining speed up hills to minimize downshifting which is just what you need when you're towing or hauling heavy loads.
