Title: VR6 Turbo timing Post by: vwmaniac on June 09, 2017, 09:07:37 AM ive been working on getting my vr6 turbo dialed in. looking at my logs i think its pulling timing but im not entirely sure. timing is not following my kfzw so im thiniking there is some intervention happening. What other variables should i log to figure this out? im going to lower the boost from 15psi to waste which is 10psi. motor is stock with head spacer, i have 630cc injectors at 3bar, hpx-e blow thru maf and a holset hx35.(http://i356.photobucket.com/albums/oo7/vwmaniac16vr6/actualtimingpull_1.jpg) (http://s356.photobucket.com/user/vwmaniac16vr6/media/actualtimingpull_1.jpg.html) (http://i356.photobucket.com/albums/oo7/vwmaniac16vr6/timing%20map_2.jpg) (http://s356.photobucket.com/user/vwmaniac16vr6/media/timing%20map_2.jpg.html)

Title: Re: VR6 Turbo timing Post by: nyet on June 09, 2017, 11:15:31 AM You're missing just about every relevant variable there is.
Here is what i log (semicolons are the things i dont) https://github.com/nyetwurk/ME7L/blob/master/logs/typical.lst Title: Re: VR6 Turbo timing Post by: vwmaniac on June 09, 2017, 11:19:08 AM thank you nyet, will my ecu support logging that many variables at once? i remember having an issue with my 1.8t notbeing able to. thank you

Title: Re: VR6 Turbo timing Post by: vwmaniac on June 09, 2017, 11:35:04 AM by research you mean look at the funktionsrahmen for the relevant timing variables.
Title: Re: VR6 Turbo timing Post by: nyet on June 09, 2017, 11:36:40 AM Let's put it this way: you'll have to learn that anyway. There are no shortcuts.
Hell, the important ones are in English for you already in the ME7L defs/aliases file. https://github.com/nyetwurk/ME7L/blob/master/defs/me7_alias.map Title: Re: VR6 Turbo timing Post by: vwmaniac on June 09, 2017, 11:48:19 AM ok cool, will do. thanks again

EVERY rod bearing has spun believe it or not the log above was made on this motor just a few miles before i dropped the pan, took the car out to get lunch and heard some tapping in the mid range and was puzzled as it was quiet at idle and under load. i drained the oil and saw signs of trouble.(http://i356.photobucket.com/albums/oo7/vwmaniac16vr6/drainplug.jpg) (http://s356.photobucket.com/user/vwmaniac16vr6/media/drainplug.jpg.html) (http://i356.photobucket.com/albums/oo7/vwmaniac16vr6/bottomend.jpg) (http://s356.photobucket.com/user/vwmaniac16vr6/media/bottomend.jpg.html)
