Made a few tweaks to 27.4. To make things confusing, this 27.4 is different than the previous 27.4 I posted here for a few of you. So you'll have to update it. But, pending any complaints, this 27.4 will be published. If any of you encounter any issues grab a log of them. Only changes related to mid/low throttle.

Just remove the cover and look.
You can not run ISO hex without diodes being removed.

Well really its going to say G5 or ISO on the black box in sharpie marker but all you have to do just to double check is open the box(dont be scared your going to break it because Terry made it to where it can easily be open) and see if the two diodieds are there, or not there. If they are there then cut them off if you are planning to run ISO. Its pretty simple once you know about it and are comfortable taking it apart. Its in the N54 G5 ISO firmware thread.

OK made some addl firmware changes. If using the BB back end flash sure to update that as well. I received exactly zero logs on 27.4 so hopefully we can get some more this time around.

PS. No update to the Cobb maps at this time but I may do a final update and post them shortly.

The problem with Cobb is they won't unlock our maps so anyone can open them. I'll try emailing them again on that.

Fine, here

27.5 plus updated pump flash to latest (FYI my bin with your tables). Some partial throttle logs and the last one has a short WOT in 3rd, best I could do tonight.

Overall felt a better at lower RPM and partial throttle. I still get a few rough 'crossovers' under higher boost but much better. 1st gear starts feel better but I did notice the surge effect once. Not sure if it was in one of those logs or not. Let me know how this looks.

Terry, I went to work with the 27.4 and did not really see any difference from the 27.3. After work I loaded up the 27.5 and it seems smoother and better. Not much of the oscillation at 3500rpm either. Seems good. I will try to log and send you something in the next day or so.

Not yet....work is killing me right now and really need to pay attention while in Tuner Pro because I'm not really familiar with the program (had help on the initial flash upload).

I updated all the BINs to reflect the change so you can just download the proper one and load it.

27.4 has been pretty good to me so far (the new one). Will load 27.5 tomorrow after work and report back.

I'm getting closer to a good 10/12 setting along with using the 1st gear boost limit to reduce the oscillation issue. I think it's a combination of PID oscillation, and traction control (DTC traction mode, not fully on). I even have an LSD but I think traction is still an issue particularly as the temps go down.

Updated to 27.5 and the E85 AT flash tonight. I never had much issues with the throttle and most of it was when it was cold. I let the car get good and cold before I took her out. No issues with light to mid throttle at all anymore.

I also went from E60 to E70 today, but that was before updating.

Tomorrow I will try to get a couple of logs.
