    The Convert started a thread MHD question in N54
    So, I'm getting ready to switch to MHD from the Cobb AP. The AP is still married to the car at the moment, but I want to get my "licenses" purchased so I have everything ready to make the switch. When I connected my tablet to the car I got the error below when trying to access the MHD store. Is this because the AP is still married to the car, or is my cable, also shown below, the problem? For reference, I have used that cable before for connecting to the car to code injectors. Any help is appreciated.

    The boost mean spikes in that area quite considerably and you have a throttle closure post shift. I had similar problems with throttle closures during shifts on my DCT. I just changed my load curve to taper more aggressively towards the line so when it spikes during shift it is matching the new boost target. Not an ideal solution but seems to be the only reason the factory tune doesn't suffer the same problem. Try increase the boost target post shift and see if it changes the corrections.

    Wouldn't that be a 'virtual' throttle angle as that engine uses valvetronic? That would make sense as running lower valvetronic "opening" down low would also come with lower duration, which is beneficial down low.

    Sticky replied to a thread 765 whp! VTT GC Dyno Update in N54
    How does almost 800 wheel horsepower sound from a 6 speed manual N54 with VTT GC turbos? Pretty nice, right? VTT hit 765 whp at 29.3 psi of boost but of course you can run less boost pressure. 28.5 psi resulted in 740, 25.4 psi in 693, and 22.8 in 655 to the wheels. Complete details below form Chris@VargasTurboTech Hey guys, We got the white car (6MT) back up and running strong and thought we'd revisit some GC numbers for your viewing pleasure. Car specs: Built Short block Stock head with bad valve guide seals GC turbos BMS DP's Custom Exhaust dual 3" into 4" Shotgun Single Barrel VTT Rear Silicone intake Custom VTT front intake VTT DCI Custom VTT Catch can set up EOS Intake manifold with built in PI Custom LPFP set up 100% E85 for fuel MHD tune by V8bait FLASH ONLY ADE Intercooler AEM AQ1 data logging set up with Dual EGT, Dual BP, Manifold Pressure, FMIC In / out temps 6MT (4th gear logs) Numbers: Now, on to the numbers. Note that we're referencing boost from the AEM logs (screen shots attached) in lieu of MHD reading it in the charge pipe, which isn't accurate. The AEM map sensor is calibrated and tested to be accurate. Datazap of course references the MHD values for those who care. 765 was made on 29.3 psi at redline 740 was made on 28.5 psi at redline 693 was made on 25.4 psi at redline 655 was made on 22.8 psi at redline Dyno Charts 765 whp dyno: 740 whp dyno: All four runs: AEM Screenshots: 765 whp: 740 whp: 693 whp: 655 whp: These numbers speak for themselves, but any comments from competitors or their pawns about these reaching a bottle neck around 650 whp should be recognized as the marketing gibberish that it is. These turbos are veryefficient. 600 wtq at 3500 rpm and no wheel spin on the dyno!

    I've posted about some of these a couple of years ago so sorry about the partial re-post BUT has anybody actually seen any difference by changing any of the following tables? Torque Limit Offset Torque Limit Offset A Torque Max Intervention Mode (some say raise, some say lower, some say leave stock)

    They were all stock at the time of starting this thread. I was hoping not to have to lower reported torque, but I have started to lower it in the LTT1,2,3 now. The area where torque limit 4 is active is narrower, so I'll go a little further and log again.

    Here's a log from today with boost tapering a little from 6000rpm and gear change a little earlier. This keeps it within the limits of the LPFP and rail pressure is OK. Lambda is fine throughout the run, including the gear change. Still two big timing drops. Yes there is a difference between bank 1 and bank 2 STFT. I'm not concerned about it. It could be the age difference between the two banks' injectors. I don't know but the STFTs are doing their jobs. They both follow the same trend and hold their AFR target correctly. Other than post-shift, it accepts a lot of timing without any drops at all. I don't believe any individual cylinder to be lean. This time, cylinder 4 had a worse timing drop than cylinder 1 so i don't believe there to be an issue with any one cylinder. Any other tricks for post-shift timing drops other than to reduce timing in that area? I don't like the idea of doing that because I'll lose performance in that area, regardless of if it's a constant run or post-shift.
