Mk7 Tuning Guide (from Cobb)

Hey guys, I stumbled across this new Mk7-specific tuning guide published by Cobb. I HIGHLY recommend that everyone reads it! It helped me better understand how our ECU's work, what different parameters mean, how to interpret datalogs, and much more .

Nice Find! Hopefully this will help a lot of members understand how the ecu works a lot better. I only glanced briefly, but I'm sure it's definitely going to help out with the JB4 users as well

I found the following interesting:

"There is currently a ~520 NM request limit in the Maximum Torque Automatic/Manual tables due to a ECU request cap that is currently being investigated."

"During development it was found that power levels in excess of ~390 Ft. lbs. could cause early clutch failure."

This is only about 380-390 foot pounds. It backs up what APR states about heir seeing DSG clutch slippage approaching 360-370 foot pounds. And everyone knows the limits of manual clutches. Does a TCU tune remove this limit? If so I suppose you better be thinking of a heavy-duty clutch pack for your DSG.

"The stock turbocharger can produce boost levels in excess of ~29 psi. This boost level can generate enough cylinder pressure to cause engine damage."

What I didn't notice was a statement for how much power (fuel-wise) the stock injectors/fuel pump can comfortably support.

While they mention a dirty air filter will limit power at moderate to high RPM levels, they didn't mention how much power a clean, stock filter in the factory air intake can support.
