How you solve the issue would depend on exactly what your issue is.

Slow cold starting is either a fuel pump issue or a fuel scalar issue. Email in a log and the BEF loaded and I can check it out. We had made some revisions to the cold start tables and I'm not sure if they have been posted yet.

I think I sorted it out terry.

I changed futureDbit 2 on increasing fuel crank pressure and also changed FOL to 70.

I'll run some logs for you and see what you think also just installed new NGK 2 step plugs i got from BMS gaped to 0.20 and car seems to run sweet this morning on the way to work loosing traction in 4th is a good sign lol....

i think the E85 in Australia is really strong as iv seen on other members posts needing to lean it out a little with some 98.

Hi Terry,

I bought JB4 last month and using on my car (F82/M4) now. In my country (China) only have 93 Octane (98 RON), no E85. Can I used this S55 JB4 BEF for my car? I am worried that it will damage my engine.

Load up the RACE BEF and post a log on map2 to start so we can evaluate it, should be fine.

I want to ask if I use RACE BEF, any hardware(ex. NGK 97506 etc...) should upgrade?

My modification below now:
1. BMC filter.
2. Full akrapovic exhaust.
3. JB4 (map 2).

Terry, Ive attached a log of a run through the gears. Using map2 with backend RACE map. I topped off my tank with 2.1 gallons of E85 for the first time. Just hoping you could take a quick peek and let me know what you see.

Is there anyway to see E85 content on my JB4 mobile app? The E85 gauge just reads 0 always. Thought that might be a readout of ethanol content. I have no way of measuring otherwise and dont know how many gallons would equal out to E30-40.

Thanks for your time!

Please Help.....!!!

I flashed BEF Via MHD today. I followed official structure and flashed successful(RACE BEF and MAP 2). But When I tried to log data, I found that sputter and misfire @ a high RPM in 3rd, 4th gear 6200rpm.

It showed error on my car and error message below:

[QUOTE=CICCO;625977]I'm having a similar issue also running full e85 and bef e85_IGN.

Was working very well for about 2 tanks of e85 and now it's struggles to start sometimes and the exhaust burble dosent work all the time for some reason.

I have tryed to flash the bef 3 times now and it's still doing the same thing.

I hope MHD are working on it ASAP or is this something you can assist with terry?

FYI I have ordered the 2 step cold spark plugs from BMS would this help the situation?[/Q


Just thought I'd offer my experience here being in Melbourne. I'm running E70 so I can run 25-26psi with no fuel issues and pump out 370 plus rwkw on the Mainline dyno in Oz. My car is totally stock hardware even OEM air intake and plugs (gapped closer). There has been a few Stage 2 s55s with different flashes of course with *** and fbo hardware on the same dyno making only 320rwkw. So I'm very happy with my result while maintaining full refinement 😁 Logs are spot on as verified many times by Terry and Payam.

I'm also running the earlier high timing jb4 s55 E85 IGN flash before cold start fuel scalar adjustment. I found after the fuel scalar revisions it made my car stall when using the stop start function. No issues at all with the earlier version.

Hi Terry

Im running the version 13 E85 ign file one of the earlier high timing flashes before cold start fuel scalars adjustments ( I found these adjustments detrimental to my stop/start function and would often stall).

So my question is do I need the revised XDF files too?

My flash is the original high timing v13 ign E85.

The XDF files are only relevant if modifying your file. If what you have is working well for you roll with it!

On the fuel scalar revisions make sure the JB4 side cold start option and open loop settings are adjusted or you can have issues with the new maps.

Ok tx Terry. Yeah so in the Jb4, I have enabled FUD Bit 2 E85 cold start... and my FOL is 60. With s55 E85 ign latest version car does not start smoothly and sometimes fail to start when auto stop/start function is ON. But on the very first version of the high timing s55 E85 ign flash, it has no issues.

Also, i noticed in the dyno logs above, timing is still around 10-11 deg until well past 6000rpm.. is this behaviour set by the flash or do iats or other factors come into play..

Timing is always based on several additive factors, the base tables we set in the BEF, the IAT and engine temp factors we rescale in the flash, long term learned trims, and some other factors we don't have control over. Are you trying to get more or less timing?

Not really. Obviously as long as the flash is working as it should and timing is delivered in a safe way Im satisfied. I was just curious as to why some logs are showing even 14-15 deg of timing before 6000 rpm and whether there are other variables involved rather than just what you set it to from the flash. Obviously my iats were very high and climbing on the Dyno. Dyno fans did not work lol.

Hello Terry,

I'm in contact with MHD Tuning in Germany. I've asked about the GTS DCT tunes and they said the update
is out since two weeks and available to flash. If I'm using JB4 with MHD as BEF, I guess I gotta wait until a
new map from BMS ist out before I can use this, right? (as I don't see any GTS option in the options view).

Thanks in advance for your help!

Rgds. Rene

Sorry, me again. I found the settings. I always went in Backend Flash instead normal flash option. The settings for CS/GTS DCT flash are inside there.

Definitely! The gears are shifted harder, especially in the higher RPM range you will notice a great
difference to stock ZCP DCT flash. But I still got the jerking and kangarooing in the 1st gear... not
sure if that's DCT related or can be solved by any other flash. Driving an M4 ZCP with JB4, Map 5,
with the latest MHD BEF, GTS DCT flash and modified middle exhaust.

The jerking and kangarooing appears only with M button, S3 and Sport+ of course, not with D/D3.

PS: I've flashed it only because it's free of charge with MHD - as single tune I wouldn't pay for it...

I did the gts and in 1st kept feeling like it was slipping then hit hard after that and then goes, changed the flash to the CS flash. it went away and shifts harder than normal and no problem. I guess try and see what works for you
