I've been reading this thread since the start, and finally...

I ordered my Nexus 7 and Burgers cable. Ill be flashing this weekend w/ the race flash.
FBO 435i with 40% E85.

Any tips / tricks/ hiccups i should be made aware of that some of you may of learned along the way?

Hows everyone liking it so far on the F N55?

How are the burbles?

What are the new (if any) boost targets for map1,2,5,7?

Just so I understand, if I already have JB4 I just need to pay the $250 for the MHD license and the cost of the flash cable and I'm set? Burger provides the different maps for free?

You need a battery charger as well

Yes maps are free and in the first post.

So i flashed my DME to the Race bin. I'm running ~40% E85 maybe a little less. Used burgers cable and a nexus 7 2nd gen off ebay for 40 bucks. (incase anyone wants a recommendation on hardware).

Everything is great, throttle response is better, car is, as everyone says, smoother, and feels like i'm getting more speed from less boost. Car is def less laggy and idk shifts even feel smoother/faster? Maybe thats in my mind.

One small issue however,

Map7 or map5, seem like when its targeting higher PSI, above 15/16 when i'm going wot sometimes, when it climbs up in the RPM range ~4k or above the car starts to sputters sometimes , pretty bad to the point i have to let off the throttle. Only during WOT, if i let off just a little it goes back to normal. It really started spouting off when i ran my own map6 which has been solid for a year targeting to 20PSI and tapering off but i dont think its happy with that now combined with the BEF. It only has happened to me in 3 and 4th gear. I haven't gone W0t above that and i assume because i have low 1st and 2nd gear PSI targets it wouldn't be evident in those gears. I need to do some more testing but wondering if anyone has experienced this already?

Again doesn't happen all the time but sometimes. Attached is a log.



Question1: the same rules apply to PID tuning (From terry's original post about how to do it) for map6 with the BEF?

Question2: Is race.bin or E85.bin flash recommended for my setup? Both descriptions say they work in my target E85 range (40%). Or is the E85.bin more for someone running higher mixtures than 40%?

Question3: I ran, what i think is pretty ragged edge for stock turbo and fuel, and sometimes i even have my FOL 75-80 trims near max. Can i back down off those settings since i assume the fuel is being manipulated now directly on the DME

Thanks in advance!

Hi Terry,

I noticed the PWG1, PWG2, and PWG3 files are a .xdf. Do we need to change the file name in order to load the BEF? When going into MHD app and navigating to backend map I am unable to see these 3 files. Thanks in advance.

Please do let us know how it goes.

I am working through this issue right now, myself. Map 7, E85 BEF Map with about 40% E85 and a nasty sputter that stops the show at 80mph @ WOT. Every time.

The logs are not giving any viable reason for this (at least Terry and I cannot find any) and my plan is to go through the O2 sensors next and then back down the E85 content. I've already done both MAP Sensors and MAF Sensor.

This was a very infrequent (and not nearly as bad when it did) occurrence before the BEF was loaded but I also upgraded to Rev4 board close to that same time period in order to resolve other issues.

There should be .bin files for all of these in the zip within the first post.

I guess there is no PWG_pump flash then since there is no bin file for that

Use the RACE file on that one to start.

Iíll report back ASAP. Just put 4.5g of e85 and filled it up yesterday but of course itís been raining for 2 days. Iíve never had it happen before the BEF and Iíve been all over the place to the edge and back w map 6.

Hopefully get a few pulls in Tom. Also changed to the e85 flash. It almost sounds like itís trying to burble in the middle of the pull when things go south. If it does it again Iíll orobably reflash wo burbs see what happens next. Will report back soon.

Alrighty - so i got some good pulls in today map 5, 7 and my own 6.

So 5 seems to target too low of boost for me. Map 7 even though i don't see a reason for it won't hit targets PWM is not maxed out, trims are low (shrug).

Now my map6 i tweaked it a little, its nice to see my trims are well below 49 (lol) now with the BEF. Hitting targets with little timing pulled on a brisk day.

So now "Map6 good pull" was set to max target 19psi taper and it was a beast no issues what so ever trims low & no sputter.

So i decided to up the boost to target 20PSI and thats when the sputter happened. (Map6 sputtet) Same spot, 3rd gear, past 4k (which is where i targeted 20psi) so i don't get it because timing is fine, my trims are half of what they used to be when i targeted that before BEF. Only thing i can see is maybe i'm running too rich? 13:1 seems a bit rich for n55 from my understanding, i could be wrong. Or i'm just over boosting too much since i'm hitting over 21psi.

I think i need to do some more pulls and re-read the map6 pid tuning thread and tweak my settings. I think i may of had over boost protection on 19 i can't remember exactly but idk why that would sputter.

So for now my Map6 target taper to 19 is where ill stay I think i need to redo the PID tuning in light of this new BEF and do some more testing.

Terry please help me understand FOL now that we have a BEF, does it's utility change? I mean i'm hitting 20PSI with under 30 trims and FOL at 70. Crazy!

Ok did even more testing on map6 - looks like no matter what i do i overboost to 21psi + usually 21.xxx and thats when the sputter happens. Could it be because its reaching the limits of the tmap? I have no idea why its doing that though because i have boost safety set to 19 on my latest pull and targeting 19psi taper down. Will lowering the duty biases help? I wonder if i should get a 3.5 tmap since i'm hitting 21PSI + easy and trims/afr are all low with some room to go.

If i upgrade the tmap and target 22PSI will that mess with the jb4 or BEF since its only looking to make max 21 psi factory

So pull after pull after pull today i'm over boosting to 21.33and it starts to sputter out. even though 3rd gear max boost is sent to 19, boost protection is set to 19.

Anyone have any tips on how to stop map6 from over shooting its mark?

This was a very infrequent (and not nearly as bad when it did) occurrence before the BEF was loaded but I also upgraded to Rev4 board close to that same time period in order to resolve other issues.

So as of right now i just set my boost target to 18 PSI and it overboosts to 20/21 without the sputter or hitting the limits of the tmap. I reset my map6 to default and going to retune it but i'm over boosting in every map so :shurg: until we meet again.

OK after all these silly posts i figured it out. I wasn't apparenlty saving my changes and i kept reverting to bit 69 or no BEF loaded. This was causing me to overboost all the time.


Now I toggled on my BEF its hitting consistent every time, no sputter. Here is my latest pull man it looks so nice. Hitting target PSI. trims are in the middle, afr is in the 13's and timing is 1. woohoo. need to dial in the duty biases again but this is def making me think i can get a 3.5tmap and go for more boost on stock. Ill report back later.

Thanks for letting me solve my own problem lol - you learn the most that way i suppose.

Solution: If you're sputtering verify BEF is ticked ON under FUD, then when you complete changes make sure they are saved.

Hi Terry.. would I be able to trade in my rev0 board and pay some sort of upgrade cost to get the new one?

Hi,
There's a problem to use MHD stage2 + JB4 map3 or any other map?
I like the linear response and xHP support of MHD stage 2... So far no problem at all.

Interesting!

I am F10 so my FUD requires different numbers because we unlock our dash access through here (in addition to specifying BEF etc.).

I double checked it, though, and everything is as it should be.

Thanks for doing the legwork!

+1 for same question because I have done this as well since BEF maps here aren't supporting xHP options yet.
