Thanks for the link, great info, Glad to know all maps configs thru your log.

Before jumping straight to Stage 2+ MM, I wanted to take some logs of stage 2 MM with different E%. Just got home. Unfortunately Car turned into Limp mode on 6th pull.

First, I added 25% E85 and drove 30 minutes after the flash.
Pulled 3 times, looks ok.
https://www.bootmod3.net/log?id=6415...0b43b90e351ab6

Then added more to 34-35% E85 and did couple pulls,
1st pull everything feels great, car felt strong and consistant.
https://www.bootmod3.net/log?id=6415...729bc86d8d36f3

2nd pull had a hiccup in between, exhaust had a really short burble sound(~0.1sec). nothing more.
https://www.bootmod3.net/log?id=6415...0b43b90e351abe

3rd pull turned into limp mode
https://www.bootmod3.net/log?id=6415...90c6177ea5458a

I noticed overboosting issue, dunno why. other than that, everything else looks ok. DSC OFF.

Sorry for posting Stage2 MM data in Stage2+ MM topic. thanks for helping.

Diagnostic Codes below from both BM3 and Bimmerlink:

Hmm, I wonder if one of your new plugs or coils are bad?

Also take a look at some of my logs and turn on some of the BM3 flex fuel parameters so we can verify that your flex fuel set up is working correctly.

I would also send the logs to PTF.

Yes, already sent to PTF for advice last night.
I'm using bm3 IOS version. It looks like PTF disabled all (RAM) or flexfuel parameters for IOS version. I'll try to reinstall to see if it work. (Edit:It fixed after the reinstall)

I was comparing your switchable stage 2+ E30 map test with my logs, parameters curves look similar. I couldn't see anything major happening. Maybe bc I'm running stock turbo/OEM 0.33''-0.35'' gapped borsch plugs?
Let's see what PTF says and I'll do more logs next Monday. Have a nice weekend.


BM3Flexfuel kit functions : sensor, map switching, anti-lag are working well.
Tips: I followed your experience to wait 2min(surprisingly exact 2min LOL) after filling in E85 with engine on, also usually it will go up 3-4% after couple minutes driving/couple heavy throttle. very consistent.

I think stock gap is 0.030” or so, but I’m not sure. Maybe bringing the gap down some or a diff set of plugs would be the next thing to try. Other folks may chime in, tho.

I think stock with Bosch plugs is 0.032”. I’ve heard of guys gapping them as low as 0.028”. The one step colder NGK 97506 are often recommended to be gapped as low as 0.022”.

IMO folks should start with stock plugs and stock gap and let the condition of the plugs indicate whether to go to a colder plug or a shorter gap.

I still have a new set of NGK stock gapped ready for it.
BTW, PTF respond my email and said they updated all N55-M2 maps and they are ready for downloading today. Halim said it will fix all the issues I addressed but he didn't mention what exactly was going on(probably related to boost) LOL./

Interesting!

I see all the updated maps. Altho, the 2+ maps haven’t been updated.

I’m curious to hear what changes Halim made on the M2 N55 maps. Nothing has been updated on the F30 N55 EWG maps.

Plugs, Coils, Injectors are all new OEM less than 200 miles, bought from FCP Euro.
I flashed MM v1.2 and turned bunch of RAMs on according to your logs. I also turn on Misfire Count Cylinder 1-6 to monitor. It's kinda happening randomly but mainly cynlinder 1-5-6.(misfired cyl 1&4 under high load last time). 2 times each cylinder during 15min normal driving. Other than that, nothing special, car feels good, idling perfect around 660rpm, no CEL.
I'll try to gap down to 0.028-0.030'' first and update logs with new version map.

Yeah, it’s odd. I wouldn’t think you’d need to gap down for the Stg 2 MM, maybe the Stg 2+ MM.

Another thought is maybe one of the plugs isn’t quite right. I might do an FCP Lifetime return order and gap the new set of plugs down to knock out two potential issues at once.

Could be coils. The stock coils can be kind of weak especially when old.

He’s replaced all coils, injectors, and plugs recently. Could be a coil if he got a bad one, but probability would point to a plug?

Ah I didn't know he replaced the coils. But it is on 3 cylinders, so it would be 3 bad plugs that isn't good.

OP did you by chance use antiseize on your spark plugs? What kind of plugs are you using anyways?

I don't know if they antiseized them or not. Plugs are OEM 330A, stock gap 0.032'', according to plugs discussion in N55 forum. Coils are Eldors. OEM EU6 injectors
anyway, I'll try to log v1.2 map with new RAMS parameters this weekend without changing anything. Maybe there are some clues thru the data. Hope I won't blow it on freeway LOL.

Ok all the parts are good.

1) If you used antisieze that is a huge red flag. These plugs are coated from BOSCH so that they do not require any antiseize and will never get stuck in the cylinders. Anti seize can get onto the plug tips and foul them, and then cause massive misfires. So you should check with your shop.

2) Did your shop register the new injectors? That could be another issue, because even stock replacement injectors are never exactly the same, all injectors have small tolerance differences so you must register them to the car.

1) I didn't recall antizieze been used.
2) I just called them, and of course they said they coded it. To eliminate this, I scheduled another appointment next week to recode.
Frustrating.

The thing is you need to be able to read the numbers on the injectors to code them. So they might need to come out again, and that means new seals and couplers. I can't remember if they're on the boxes, but problem is you don't know what cylinder each injector went into, so a box is useless.

EU6 injectors don't need to be coded. But if he wants to code them, The calibration for EU6 is 215. I've bought 2 sets of Bosch injectors from FCP and all 12 had 215 for the calibration value.

Oh yeah that's right eu6's only need to have the small mixture adaptation reset performed.

How to do mixture adaptation reset?

btw local shop called me and they confirmed 200% they coded as a standard injectors swapping procedure for every bmw. so I guess I need to trust them on this. Also I checked my log again, lambda and bank 1 seemed perfectly match up. I think it means two banks are pretty even also my A/F Ratio looks fine.

What will happen if I add more E85 to E50mix to run Stage 2 MM, would it be better for ignition or even worse under my condition?

Do you guys need me to flash to Stage2+ MM to log some pulls so that it could be easier to check data?

You can do it through ISTA, and very likely protool (can register injectors and code the diff, dsc, and power steering).

I literally just wrote up a review on protool: https://f87.bimmerpost.com/forums/sh...php?p=29968185
