Ok guys, I have been playing around with the new MHD XFD. I studied the n54 vanos variants for stock, hybrid, and singles. I wanted to play around with the new vanos tables. Backpressure has been a potential issue for this platform for a while. I build some vanos tables that increase the value for intake and exhaust. The intake is increased more than the exhaust, which increases post spool LSA. I also made a timing table that takes some timing away (.5) just from the high spots in the PI e85 bin timing tables. I randomly get timing corrections that I dont like, so I wanted to try to make the tune dialed in for my car. The vanos and timing changes where minor.

I am not suggesting you guys use this bin. I have had the cleanest logs and hardest pulls since making the changes. I have logs but my jb4 mobile is not emailing them out for some reason. Car is running like a absolute beast. If these vanos changes are in the right direction then I am sure terry and the like will get us dialed in at some point. Vanos tables and LSA changes range from 2-5 only in certain places.

For those who are interested take a look see. Only tables changed where timing main, vanos in and ex warm.

Note my mods in signature. Not sure if effective for other set ups.

The bin is too large, says limit is 97mb. Who can upload this for me?

If interested and you have the same mods, send me your email.

I feel like my car takes a tad longer now to respond after going WOT compared to ppk flash/old cobb BEF etc. i know menu 11 increases sensitivity but thats not doing it for me set at 4. i dont remember the cobb BEF feeling as slow to respond, has anyone else noticed this or is it just in my head?

It's a flash option that can be applied to any map.

Terry, does your 5.12 test software include the 4/4 option to disable the JB4 completely?

Thank you

It's in there but not tested. After selecting 4/4 you'd also have to put the blue solenoid connector back to stock to bypass the ISO wastegate control.

Newguy, is it possible that the slow response going WOT is due to the volume of that massive intercooler you just installed?

No I don't think so, I've been trying a few things on my car as of late one of them being ppk as a BEF the other being flash only no jb4. Both of them felt normal. This was something I noticed ONLY after loading the BMS pump flash.maybe I should try re flashing possible something loaded funky with the write if I'm the only one

Which BEF for PS2 E50 no meth or PI?

I have TBI just not connected due to not being able to get it dialed in.

or should I connect the TBI and run the larger turbo injection map?

Interesting, please let us know if it is resolved when you reflash.
Also, have you made any progress with your misfire issues?

I'm flashing the bef 102716 pump map right now, what is the process for updating the maps as Terry provides them?

Is it:
Set JB4 to map 0 and then flash the updated map via MHD and then select jb4 map one flash is completed?

Since 4/2 is already enabled, no need to set that again right?

Select map0 when flashing, then go to map1, map2, etc, after flashing. You select 4/2 only once to get the JB4 in the proper mode. And email for v5.12 JB4 firmware.

BEF is running great, stronger than JB4 only especially on pump fuels.

Terry,

VERY impressed by the 10/27 maps!! Are there any changes to the 11/6 maps other than the cold start control?

With the factory BEF the JB4 is optimized for higher timing, less boost. With the BEF we optimize it for more boost, less timing. With the extra fuel control we're able to run things a little more aggressively as well. Overall well worth the extra $200 to load it IMHO.
