Cold start
 - Often high ethanol content fuel be difficult to start in cold weather.
       No cold start worries with United Motorsport Pro-Flex.

Ignition Advance
     - Ignition mapping is critical if you want to optimize the gains that
       ethanol can provide. United Motorsport software will adjust
       ignition advance based on the percentage of ethanol. This ensures
       high torque on high ethanol and safe advance when you return to 
       lower ethanol content.
Boost limitation 
     - The stock fuel system was not designed to meet the flow requirements
       when running high ethanol content and increased manifold pressure.
       United Motorsport software will raise or lower maximum boost to keep
       safely inside the flow capability of the fuel system.

     - No user adjustments required.
     - Just add ethanol and go !



The famed single 525 Walbro pump and PM4 controller are better suited for the front wheel drive MQB vehicles GTI & GLI with a non-saddle FWD type fuel tank. There is a fair amount of loss on the siphon side of the AWD saddle fuel tank equipped cars. This loss doesn't apply to the FWD cars. It's roughly 14%; this means you will not get 30-34 PSI on your selected hybrid turbo on E80 unless you have a Brushless pump or a Dual 450 pump set.

You can achieve 30 PSI safely on the hybrid of your choice with an E46 Blend with a 525 FP and PM4.

Some clients state they want a conservative tune, however they don't won’t blend fuel to achieve the best mixture for the less potent parts they selected or were steered to purchase.

The UM ProFlex tune will cut boost based off the fuel delivery and Ethanol contact, If you don't have enough it cuts the boost to save the engine.
