Software Module One

• The Fuel Saver software. MPG gains vary, in most cases a + 2 MPG has been reported. Please note that the timing in this software is rather aggressive. HEAVY TOWING is not recommended with this software setting.

Software Module Two

• This software increases the fuel delivered by the ECM.

Software Module Three

• Same as software # 2 but the timing has been added.

Software Modules Four to Nine

• The even numbered software is identical to the odd-numbered ones, except for the timing. The software setting without added timing is intended for use with timing-adding boxes.  The power gain at top RPM with these software settings is almost identical.
• These settings differ greatly in HOW they get there. Than higher the software number then more aggressive the throttle response from idle speed up. Aggressive to the point that the software modules Eight and Nine can become difficult to handle on slippery roads.
