Hi all,
I'm attempting to replicate the ME7.1 nefmoto community tune onto ME7.1.1 (C5 Allroad TIP). I understand there are some differences, in particular the PID behaviour -
http://nefariousmotorsports.com/forum/index.php?topic=12352.0At this stage all I'm trying to do is add some boost via LDRXN and some fuel at WOT with LAMFA (plus a little timing adjustment). Here's how that looks

This has resulted in a flat spot at around 3000rpm. Happens on every pull, some worse than others and more noticeable in 3rd compared to 2nd. Car pulls nice up to 3k, falls on it's face, then pulls nice again up to redline. You can see in the graph below the RPM's drop a little when this happens, seems to be right before actual boost reaches desired. The calculated AFR is concerning (15.6!), but is that the cause or an effect?

And a huge drop in power

The desired boost follows actual nicely, so DV's and N75 seems to be working as they should. Though there appears to be a fuel cut based on injector DC

Is this an intervention of some kind? Logs attached have a 2nd gear pull uphill that wasn't bad at all, followed by two 3rd gear pulls. Greatly appreciate any assistance.
