This is how I went about flashing my 2.5 lpt M4.4 ECU
Tried putting a battery charger on the battery to get the voltage up to 13.5v, the battery charger would only raise the voltage to 12.5v.
Borrowed a charger/booster which raised the voltage to 13.1v

On the Wiki site it states the voltage needs to be 13.5v but I`ve found that aslong as the voltage is greater than 13v it will flash the ECU.
Using the software and bin file from the wiki site started flashing ECU

The only change I`ve done to the bin file is to lower the tickover from 900-1000 rpm to 700 rpm.

I`m not going to go to mad with this ECU until the forged engine is up and running................. then the fun begins :)
