MAF Manager Rivazza – Automatic or Manual Fuel Tuning

195

Suitable Uses

Increase engine power by adjusting engine fuelling from stock settings eg stock settings are excessively rich and you want to lean out the fuel

Tune engine fuelling to optimise bolt on engine upgrades eg intakes, camshafts

Mild engine swaps eg SR20DE swapped with SR20VE. Generally when the engine has been swapped with one of a similar capacity and are from the same engine family.


Initial setup

Check wiring. 

Open SET menu and check that the unit is receiving data from the sensors LOAD, MAF and RPM

MAP menu. 

Set your RPM and LOAD split points.

Set your “Fixed Multipliers”. These should be a ball park figure. eg if you have 20% bigger injectors, fixed multiplier initial value should be 0.8

Driving

Take it slowly to start, check your AFRs. As you drive. When back in the pits, check your fixed multiplier and adjust as required.

If you are using the auto tune function

Set your AFR targets

Take it slowly to start. When back in the pits, check your dynamic multipliers. Are they within 10% of the fixed multipliers? If not adjust your fixed multipliers. Repeat until Fixed Multipliers allow full range of adjustment in the autotune function
