Why choose an RSR Air Shift Module?

The Air Shift Module (RSR-ASM) combines all of the features many racers want into a compact, digital package loaded with adjustable features.  

Coil or Fuel Injector Kill Mode allows the user to install the RSR-ASM to best fit their combination.  Engine Kill Times are adjustable per gear shift.  This is great for those with 1-2 or 1-2-3 Auto Transmissions, or those who may need to adjust kill time for added power down track.  Adjustable Solenoid Advance Time allows the solenoid to apply pressure to the shift linkage before the engine kill sequence begins to allow faster shifts with less delay.  Auto Shifting built right into the controller with no need for added boxes or chips.  Can be wired to ground or +12v shift buttons for manual shifting.  Works on any motorsports engine with a digital ignition (Not CDI – MSD for example) 1, 2, 3, or 4 Cylinders.

The Air Shift Module comes with the connectors you need to get the job done.

Questions and Answers

I’m not able to program the ASM. – The ASM will only allow programming changes with the activation signal is off (yellow wire).  If you are not using a toggle switch on this yellow wire (recommended), then you’ll need to remove this wire from it’s 12v source so you can program the unit.

My Auto Shift is not working.  – First, make sure the unit works properly when shifting with the push button.  This will ensure you have everything wired properly.  Next, make sure you have enabled the Auto Shift function.  Now start the vehicle and look at the ASM display.  Engine RPM’s should match the readings on your tachometer.  If they do not, enter into the menu of the ASM and adjust the “pulse setting” until the display reads the same as your tachometer.  Once this has been verified, set the shift RPM to a low RPM (must be above 3500 RPM) and go for a test ride to make sure the unit auto shifts.  Once this is verified, change the RPM settings to a higher RPM, but lower than your normal shift RPM.  Since many factory tachometers are not accurate at high RPM, we want to make sure you are not hitting a rev limiter before your set RPM.  If the unit still does not want to shift after changing RPM, inspect your tach wire connection.  If this signal is not clean, it can become inaccurate especially under load and high RPM.
