I've spent the last few months bringing a 1996 1z TDI Passat back from the dead. It had sat for about 10 years. 250k miles. I've done a ton of work to get it roadworthy. It's roadworthy now, so I am pursuing getting nozzles and a tune. . That journey has brought me here. I've been reading about edcsuite and winols. The ecu 028906021gq is an msa15 which has 2 chips for fuel and boost that can be programmed with minipro tl866cs. I would like to learn more about this process. I make my own biodiesel and this car really likes it. I do all my own wrenching. Used to own a 03 Jetta alh TDI with nozzles and a tune. I miss that car. Thanks for listening and letting me join.
