Has anyone ever had fuel trims and O2 correction without having an "Actual Lambda" reading in maestro? Mine is just stuck at 1.02?

O2 sensor is brand new. trying to work on fixing a lean condition at WOT

Also, is there any other community resources for asking Maestro-related questions?

A fb group? Another forum that is active? I've started threads, commented, searched, etc and don't feel like the support has been great or huge.

Ive been reading this forum for a couple of months and have read every page, planning to big turbo my 20th and wanted to use maestro 7. but it seems like this thread has died or is slowly dying. almost like no-one wants to self tune or help anyone. i would just search Facebook on those "mk4 owner" pages and ask if anyone uses Maestro and maybe they can help. best of luck:thumbup:

Thanks for the suggestion! If you don't use maestro, what are you planning to use?

I think a lot of people have moved to the Facebook page. This thread has become too big to be manageable really. Always wished there would have been a Maestro section of the forum so it would be easier to search by topics/threads. Similar to the Roos tech section

Unitronic offers a couple of “off the shelf tunes”, but personally I look forward to the challenges and being able to tweak my tune. I’ll be going with a big turbo this summer as I have other things to focus on in my life this winter. But I will keep this forum updated as I start to tune. Let’s help bring this forum back!

I’m having an issue with my NLS, it’s not my clutch switch. When I use a VVT file , my Ecu doesn’t register my clutch signal. If I use any other file it works. The car is a 01 with aww Ecu , it uses two clutch switches , one for the starter and the other for cruise control? . I contacted eurodyne about this and their response was “use a non vvt file then” . Has anyone encountered this , is there a way to fix it ? I’m thinking that the file maybe for newer cars that might only carry one switch ? Any insight ?

Is there a database of files somewhere? Specifically ones for bigger turbo / injectors applications? Alternatively, are there any tuners in the NYC area that specialize in stuff like this? Thanks in advance! :thumbup:

Misfires and rough idle on MKVI with Stage 2 Maestro tune

Hey guys, I'm currently dealing with a rough idle and misfires on all cylinders (Sporadic) whenever I clear codes and start the car. Any thoughts? Could it be a AFR problem? TBA?

Plug type and gap? Coils? Coil harness? Vacuum leaks? Smoke test? O2 senator condition and age?

Etc..... etc..

Alright guys. How do you figure out the numbers in the graph? Mathematical equation. I'm learning so I am having a hard time with what it means. Ex. At 50% load and 3000rpm I'm at 30.7500.. how is that calculated. Any help would be seriously appreciated
