I have a good ECM that is setup for the powerlogger. It isnt modded but its the part number 148. These are the original ones from the factory. $80 shipped.
I have a modified ecm to run Low impedance injectors and a powerlogger installed on it. I also have the Scanmaster 2.2 to read off the powerlogger/ give you the wideband rdgs on the scanmaster. What injectors you running?
