BMS back end flash in UK/ Europe

russjonesr · 02-13-2015, 11:37 AM

Hi Guys,

Anyone in the UK or Europe running a BMS back end flash?

Cheers Russ

russjonesr · 02-14-2015, 09:21 AM

Okay Guys..

Took the plunge this morning and flashed the DME with the BMS race flash...as with these thing the first time is always nervous but Trebila from the N54 tech forum gave me some sound advise ( he runs a BMS flash in France)

jamesmurray · 02-14-2015, 04:46 PM

I've been running the backend pump flash for about 6wks now. Are you running the race or e85 flash?

James

russjonesr · 02-15-2015, 08:14 AM

Hi James, running the race flash ..... i have meth so should be okay! I will keep you posted

Scotty89 · 02-17-2015, 09:24 PM

Edit: I'm in Australia, but I believe we get the same Euro spec deliveries that you get in the UK.

I borrowed a cable from a local forum member and flashed to the pump flash, to try JB4 + pump flash.

I found that pump flash reduced the waste gate settings and targeted much lower timing, but increased the boost targets.

Overall it made the car sluggish, boring to drive, and less powerful.
I felt like the immediate power from mashing the pedal was actually quicker in stock form than JB4 + pump flash - however the pump flash gained more boost up top and therefore didn't run out quicker.

I flashed back to standard and continue running JB4 + map 5 + 30% E85 and it feels much more powerful than JB4 + flash, and has greater low end response than stock.

There is something not right with the pump flash and my Australian (Euro spec?) car. The logs all showed great smooth curves, no problems with boost, fuel or timing... but the car was just incredibly slow and sluggish. Other Australians have said that the pump flash did wonders for them... not sure why mine didn't.

I know exactly what you are talking about! Where the ignition timing has been dialed right back to allow for more boost it looses some of the sharpness compared to when running on the stock flash. I've noticed that the top end doesn't seem as quick as before.

I think running the race flash might be the way forward if you've got access to E85 as it's got a more stock like ignition profile.

What should someone with JB4, stock turbos, meth and down pipes run?

I'd only use ethanol occasionally. 99ron fuel.

jamesmurray · 02-19-2015, 10:24 AM

Well on the pump flash i can hit 16-17psi (low down) on 95ron, so using meth with the pump flash would be a bit pointless I think. Your best either sticking with the stock map or go for the race flash (although this has more timing advance than stock iirc), so you had to make sure the meth is working/setup correctly.

Hi I done the backend pump flash on a fbo n54 in the UK on Saturday. I've had nothing but problems since, and exactly what scott said, my car feels sluggish and the throttle response is rubbish now! Also getting a 2a13 dmtl code!

Last time I compared flashes, the pump flash was less aggresive on timing than my stock bin file. So I wouldn't use the pump flash. I'd only run the race flash if you have meth injection.

johmei · 02-25-2016, 05:20 AM

The BMS backend flashes should not be used out of the box on Euro cars. You should move the relevant changes over to your stock bin file and leave out a few items. DMTL code comes up because the maps are US specific and include DMTL check. Euro cars does not even have the DMTL pump!

Check out this guide on creating a Euro XDF for easy to do updates and play around a bit with TunerPRO to get a hang of it.

lukepitt86 · 02-26-2016, 12:37 PM

Thanks for the replies, I'm prob gonna flash back to stock as the backend does feel dull. I'm not very good at all with electronics or mechanics so I'm not really confident on playing around too much otherwise I'd have a go. Terry at bms said to use the race flash but I only have 99Ron UK fuel and no meth or e85.

Cerbera9 · 02-26-2016, 12:48 PM

I use the MHD race flash and I only have 99Ron UK fuel and no meth. I log regularly and keep an eye on things, last dyno'd at 502bhp/520lbft and it seems fine. I usually run the JB4 map 5 and I find the response is much better then the MHD pump flash.

lukepitt86 · 02-26-2016, 01:03 PM

502 bhp? Wow that's impressive, what mods u running? Would love simular results! Is that shell nitro u use?

N54 335i - Turbo Dynamics Stage 2's - BMS JB4 & MHD - Miltek Exhaust - VSRF DP's - VSRF Intercooler - BMS DCI's - BMS CP - Forge DV's.

Always run on Shell Nitro. Next mods are inlets and Meth.

You should try the MHD RACE flash but log your results and get them evaluated

lukepitt86 · 02-26-2016, 02:48 PM

Just bought the vargas inlets and awaiting delivery! I have jb4, vrsf downpipes, bms charge pipe with tial bov, mishimoto intercooler and dci's. Almost went for the turbo dynamics stage 1 but people said it wouldn't be worth it. What hp do u think if be at with my mods? Not too sure on the mishimoto as some people said it was good and some said it wasn't all that.

Cerbera9 · 02-26-2016, 03:09 PM

Turbos are worth doing but only if your stock turbos have had it.

I would fit that intercooler and then monitor your IAT's they are bound to be better than with the stock IC.I would then fit the inlets and try the Pump & RACE flashes to see which is best then stick it on dyno to see what it's making.

lukepitt86 · 02-26-2016, 03:15 PM

Sounds like a plan, the intercooler has been installed for a year now, seems to do the job, as in I don't feel power loss as the engine gets hot but never done any logs before. My turbos function really well but got a wastegate rattle that is pretty noticeable unless my menu 10 is on or below 1000rpm. A bmw specialist is gonna have a go at tightening the rear to see if that rids the rattle. Not sure weather the inlets will do much as I'm stock turbos, hoping for a little more noise and power tho really.

Cerbera9 · 02-26-2016, 03:44 PM

I would be careful about adjusting the rear turbo waste gate it needs to be matched to the front turbo waste gate so they close together at about 6hg and is best done with the DP's off.
You need to take logs to make sure everything is running ok

lukepitt86 · 02-26-2016, 04:09 PM

Oh right, I was told to tighten the actuator arm 2 1/2 turns on the rear turbo by another n54 owner who had done this himself. Perhaps I shouldn't then. Seems a shame to spend thousands on turbos when the only noticeable thing is the annoying rattle!! 😣

russjonesr · 02-29-2016, 05:12 PM

Darren Woods will adjust them...Dp's have to come off for a proper job.
