Anyone think the stage 1 E40 is worth trying? Only mods i have is the DCI and a stage 2 lpfp. No intercooler yet to try out anything above stage 1+

Personally wouldn't bother, you can try it, if you're only gonna do 1 or 2 pulls here and there, but I'd focus on getting the intercooler first as high IAT's and lack of consistency would be main issues.

Anyone experiencing slight corrections/ misfires on v9 beta stage 2+? pardon my ignorance i've just picked up my first n54.

The car has DP's & Intercooler

Just wondering if anyone else has experience with stage 2+ v9 beta.

Could anyone recommend a tune that is proven and not beta? lol

i'm running 91 Shell btw.

thanks !

I do not have any issues running either Stage 2+ or Stage2 e30 map v9 beta.

I think consensus here is that if you want to be running v9 beta that your coils and spark plugs etc. better be on point. In fact I'm running 2-step colder NGK plugs so that might have something to do with it as well.

First point of check are your plugs and coils, find out which cylinder is misfiring, then swap coils or plugs round to see of misfire follows. If it does then replace the plugs and/or coils.

Run map version V7.1 it's been proven to be stable and it's not in beta.

I agree with other members about version 7.1. I still think it’s the best. I have been using version 9 stage2+ for the past 6 months or so. Didn’t have any issues and it seemed smooth with Xhp. However i just decided to go back to 7.1, and I noticed right away how much happier the car is on it. The idle is so stable, and boost/acceleration just seems smoother. I guess every car is different but I’ll be sticking with 7.1 for sure

Has anyone tried running the stage 2 E50 without down pipes? Curious to know if anything would happen.

[nicky dj]

I would not do that. It would be best to keep the gas flowing as much out of the cylinders with minimal back pressure with that high of boost. Also, since the turbos run leaner at lower rpm's to help with spool-up, it would be best to get all that heat out of the exhaust as quickly as possible. Your turbo seals probably would be shot in no time. I could see the ECU having errors and overboosting etc. E50 runs high boost for stock twins (20+ PSI I believe).

Yes, it's fine. Just dont track the car or do runs up to 150mph.

Is it 20+ psi on all versions or the 9.0 beta? I'm running V8 E50 stage 1+ right now and it hits peak of 16 psi.

I'm not sure, I run the v9 e30 stage 2 map and it's about 10-20 psi sometimes overboosts to 21. E50 might be the same, just different timing. Still 20psi is up there for stockers.

I wouldn't say its fine, have a look at the log, it won't be running optimally without supporting mods.

I wont even dare to try it anymore. Only reason why i asked was because i wanted to try the V7.1 flash, but Stage 1+ only supports up to 95 octane and Stage 2 has the option for E60. It's only been maybe 60 miles since I flashed to V8 E50 Stage 1+ but I'm not having any issues whatsoever so maybe I should just keep it where it's at for now until I install my down-pipes.

I ain't going to lie guys.... since the tune has a bit more miles on it with more adaptations... this car moves for having stock turbos i cant imagine on the stage 2 with down-pipes!

Pretty sure E map is available for stage 1 or 1+ on V7.1 maps.

Without supporting mods like intercooler or downpipes as recommended by MHD (stage1+/2+2+) you will have heatsoak/timing pulls and more pressure on your turbos.

You car might be running without issues but it's suboptimal due to the above.

I installed my intercooler last night. Haven't driven the car yet, but will later today. Been thinking about trying this V9.0, but i was a beta tester on my 340i and that wasn't fun at times.

I checked with my iphone and it only shows 95 octane for V7.1 for the Stage 1+

A great maintained car, stage 2 e30 (xHP) will get you to be neck and neck with stock M4's beat Mustang 5.0's, Lexus RC 350's, BMW 340i's, Audi S5's and more.

Anything under Stage 2 e30 feels slow. Stage 2 91 feels really slow now and I think that's about the same PSI output as v1 e50.

That can’t be right. There is all octane versions for the maps. I was using stage 1+ 93 octane before I switched to stage2+ With dps. This is what I see on my iPhone mhd app...

Edit: unless you were talking no E maps
For stage 1+? Then yes you need upgraded dps.

I was referring to an ethanol map on the V7.1 maps. It seems like they only have E60 and for the Stage 2 only.

Yes no full E85 on OTS,
