The ULTIMATE in professional level sensor control over the important engine sensors that are affected by the introduction of Hydrogen (HHO gas). If you are a tuner, a gearhead, a programmer, or an experienced mechanic - we have a solution for you that will give amazing Long Term Results with a well built HHO Generator kit! Unbelievable control that up to now has not been readily available to the industry.

If you are not intimidated by sensors and how they interact with the engine and the ECU, then THIS is the Tuner Chip for you! Everything Volo wanted to do, but fell short!

WARNING: Not for casual experimenter, or those that want to just drop a quick and cheap hho kit in their car. This is SERIOUS Electronic muscle - and if you install as instructed you WILL see Long Term gains heretofore not seen in the HHO industry. Very Advanced and you will need a Scan Gauge or other scanner like at Ultra-gauge.com to dial it in, but when you harness its ability- you will see gains like no others. Choose either the WIDEBAND or NARROWBAND Pro Tuner for your vehicle.


  • TSTAT to monitor engine temperature for activation cycle
  • QUAD EFIE for 4 O2 Sensors (choose Wideband or Narrowband below)
  • Extended MAF/MAP sensor enhancer - important to lean out air fuel ratio
  • IAT (Intake Air Sensor) Enhancer - to retard timing and lean engine
  • CTS (Coolant Temp Sensor) important to trim fuel leaner!
  • NEEDS scan gauge or other OBD2 reader to finely tune sensors
  • Will not harm or change ECU programming or fuel maps- works with them!
  • Must be used with well made hydrogen cells!
  • Some reported instances of 80-100% Long term gains

Be the Envy of the crowd, and amaze your friends and family with these professional level tuners and their results with your hho kit.

(The actual tuners may vary slightly from picture, as mfg is constantly refining design). 

DO I NEED THIS? If you are a beginner or entry level into the HHO kit world, then start with the advanced EFIE/MAF. If you are a tuner, like to tweak for maximum performance, want the best option for mileage/performance from your hho generator system; and you aren't afraid to get in there and play around a bit, then this is for you. 

NOT for use on Diesel engines unless your vehicle is a brand new version that incorporates O2 sensors (only a few models currently do that) - use the diesel chips for all diesel vehicles.
