Maxxtuning AB - www.maxxtuning.eu - info@maxxtuning.se

ECU installationStock Engine Control Unit (ECU) on this vehicle is mounted on passenger side floor, under the glove compartment.• Remove the carpet and the black large plastic guard, where the ECU is located.• Disconnect the stock ECU from vehicle harness connector.• Install MaxxECU harness into vehicle harness connector.• Install included MAP-sensor into engine manifold with included hose kit.• MaxxECU uses stock air temperature sensor (highly recommended to replace it to get a more accurade IAT reading).

Plugin Trigger

Audi 5-cylinder engines is using an unique trigger decoder which take use of three inputs.Trigger + HOME + DINx.It’s extremely important that HOME signal (flywheel sensor nr 2) is triggered in the middle of 2 Trigger teeths.In MTune, RealTime Data tab --> Trigger, ”Home position” which should be within 10-90% to perform best. Be sure to also check this value on higher RPMs.The only thing that controls the HOME POSITION is the polarity of the HOME input, please modify (if possible) using ”Trigger Polarity”, Inputs ---> Trigger/Home inputs and ”Trigger input”.

NotesMaxxECU has some built in output test and diagnostics, see Diagnostics ---> Output test to test certain outputs. Diagnostics ---> Output test to test certain outputs. Diagnostics ---> Output testThis will only work if fuel pump is set to ”Always active” since fuel pump relay is also powering injectors and ignition.
