With the stock flash we run less boost more timing since we're limited on how much timing we can pull. With the BEF we pull timing way down and ramp boost way up.. On the dyno, its working a little better this way.
Ok thank you terry and should i run the new 5.13 iso firmware with the bef or uts stiil beta ? Or still run the 5.12 test 9 ??

I also get 10-12 degrees of timing on the stock flash. When I use the e50 flash I only get about 3 degrees of timing. The car feels slow and it's 3 cars slower. I race the exact same car to see the difference.

Timing doesn't kick in until around 5700 rpm when it's ready to shift. So I don't understand what's the point of adding all the timing up top like if we have big turbos and hold boost up top or something. Our powerband that is useful on stock turbo is around 3500rpm to 5700rpm

You don't need to use the XDF if you only want to upload a flash map.


I think Terry was answering your first question ("Would the BEF benefit me?").


There's no e40 map on n55. But any map change is a short write (unlike MHD initial install).
So I don't need a down pipe then? I like the power of the JB4 on Map 5 but the part throttle jitters bother me a bit. Not all that smooth. If the BEF will make it smoother and if I could stay at the same power or make more, I'm all ears.

Any codes? I get more power everywhere with BEF then without (PPK and no PPK)

I know from flashing the 36BE can linger sometimes, and cause power issues. JB4 won't clear it.

+1 on why we have build up timing? timing starts out low and then climbs to 9-11* up top.

36BE is a silent code, happens while flashing. It happened on the 40min flash the first time I did the flash even when it said it cleared codes. Had to manually clear it.

I just have a feeling people who say power is less may have this code in background.

My car has more power everywhere with E85 MHD BEF vs PPK and no PPK flash.

Yes, the 5.13 has torque logging under dutycycle now, which we're using to evaluate some of the BEF changes.

Lower timings helps a lot for me. I am only running about E20-30 on MAP 7. Short log here since I ran out of room (and steep uphill), but I do a lot of logs and it's pretty consistent.

I run e50-e55 your car probably feels slow compared to mine. Your afr look a little lean to me 14-13 afr mine are in the 12s

Kind of a weird comment.... just trying to help you. You said your car feels slower. I've ran all the flashes, Cobb, JB4, JB4-Non ISO, ISO, PPK, stock flashes. I ran full tank E85 since April but running a lot less now because it's not really necessary at below 400HP. My car is spooling faster with MHD BEF then all other forms of flashes, and/flashes with piggybacks I've tried so far.

Have you posted logs? Was mentioning the 36BE code because I've had that even pre MHD. You had to clear the code with NCSexpert. Even with MHD 36BE stuck around after the first flash.

I sent you logs and you didn't know what was going on either lol

I don't understand how y'all are trying to tell me that 3 degrees of timing is making the same power with 10-12 degrees of timing lol my car is way slower with the backend flash.

If I went to the track with 3 degrees of timing I would probably run mid 12s again lol stock flash with jb4 I'm running 12.0 @116mph

Update maps, put in 5_13 firmware. Have you tried resetting all adaptations but throttle?

Also, try a log 3rd gear 2500 till red line with no shifting. Try JB4 in Map 2 first.

I totally agree with you man. Timing is power ! You would have to run super high boost with 3 degrees of timing to make same power as 10-12 timing on normal boost IMO.

Id like an explanation too. Apart from being safer a little bit ( trims. Afr. Etc.) I dont get it. Cause on stock flash vs bef these parameters have minimal differences for the power it looses....


P.S : pm me your mods and fuel and map you used for your amazing 12.0 id like to do it too this summer

Timing is power, especially on an NA engine. But keep in mind, this is very new and Terry is still testing things out. There should be better gains with faster spool and higher boost PSI with lower timing. An engine is an air pump, so the more air you get in and out. VE goes up if you can pump a lot more air in, which means more power. It's a trade off, but it makes sense to lower timing a bit and get more air in.

Or you guys can adjust the timing tables as you see fit. It literally took me 10min to open tuner pro, change the table and email it to my flasher. It's not that complicated.
