I switched back to the stock map and the car pulls without issues.
Below are 4 links of of the data log. I wish I knew how to read them, but if anyone that knows how could provide insight, I would greatly appreciate it. I also have a ticket open with PTF to see if they have any input. Pull 1 power cut: http://www.bootmod3.net/log?id=5df54938c090c6327e1563bd Pull 2 power cut (only the second pull cut hard): http://www.bootmod3.net/log?id=5df5498dc090c6327e1563c0 Pull 1 stock map no power loss: http://www.bootmod3.net/log?id=5df54e5cc090c6327e1563d2 Pull 2 stock map no power loss: http://www.bootmod3.net/log?id=5df54ef7c090c6327e1563d7 Last edited by RoIIouT; 12-14-2019 at 05:58 PM..

HPFP possible issue
Hi guy's
New here and a big thanks up front for any info. Yesterday had a full reflash tune by a very reputable company, pre tune run car was delivering 341 BHP and post tune it's delivering 411 BHP and 611nm torque. Question is the technician said he can hear a ticking noise coming he thinks from the HPFP and said it could be the bearing that actuates the pump ? they have done a lot of B58 tunes and did say mine sounded different albeit slightly due to this noise he can hear. I myself can't hear anything but that means nothing lol Did an oil and filter change and NGK spark plug change 1 week prior the tune to make sure it was at it's best. Car is 2016 stock 340i except from full cat back remus exhaust system. Had the noisy cold start removed and the sport display update to show new power levels, running extremely well and my butt dyno can sure feel the extra grunt. Is it worth me removing the HPFP and pulling the follower to pump drive out for inspection ? 29000 miles and ZERO issues so far. Anyone want to see the dyno print out i will sort it. Older dude but still love my cars Last edited by bellguy; 01-24-2020 at 12:55 AM.. |

It's normal to hear injector ticking on our engines. Sometimes you'll also hear the evap check valve working. You should be fine.

Took my 2016 340i with 50k miles in for low coolant and a rattling noise on cold start that goes away when the engine is warmed up. Rattle turned out to be the waste gate but not severe enough to warrant turbo replacement. BMW states the noise is normal... I’m not happy with that answer, has anyone else experienced this with the B58? I know this was a common problem on the N54.

I’m just under 50k miles but the car is CPO so I should have one more year of warranty coverage. I’m going to keep an eye on it. If it needs replacement when I’m out of warranty I’m just going to put on an aftermarket turbo and tune it. Turbo replacement on the B58 doesn’t look too hard based on the data that’s on Newtis.

2016 340i 41k mi
Dinan intake, vrsf downpipe, remus catback exhaust, bm3 stage 2 Car went into limp mode on sunday, multi cylinder misfire. Flashed back to stock and took to dealership. After diagnosis, bmw states scoring on cylinder 6 walls. Engine replacement required. BMW denies warranty due to dme tampering. Obviously I'm not about to fork over the $32k they quoted for engine replacement. What are my other options? Sleeves and forged pistons? Can I turn this into an opportunity to upgrade some stuff? I'm already waiting on a vtt gc turbo upgrade and have a supra pump ready to install. Thoughts? |

That's what I figured. Anyways I'm trying to look at this as an opportunity to build it better. Anyone know anything about getting the cylinders bored out and upgrading pistons and rods? That would solve the issue right? Or should I move on from this engine as BMW suggests and get a low mileage used replacement? Will the b58 from the g20 m340 swap right in? (I'm sure I'm just dreaming now...lol) anyways I'm totally open to suggestions and others experiences as this is the first catastrophic engine "failure" I've had to deal with...

I’m sorry to hear about the possible loss. Unfortunately this can and does happen in this game. Not all the time, but it does happen. I have broken a few motors in my day, but none with the price tag of a B58.
I think the next stage in the tuning market evolution of the B58 is to see engine offerings. Built short blocks, ported heads, etc. maybe... With all these new turbo offerings and the fueling mostly sorted out, people are hitting new power levels. This should increase the number of broken engines, and the subsequent need for solutions to that. The problem right now is that the B58 is relatively new and not enough have blown up to really support offering replacements. The timing is poor. There is another guy on the forum who was building a motor with Darton sleeves after he had problems. That seems to have taken way more time and effort than was expected. He knows better than me what the options are. I would try to contact him. Tyler something. A junk yard replacement will probably be your cheapest option. A built motor is surely possible, but how much and how long is another thing entirely. Probably not cheap. You can find built N54 motors online for under $10,000, but those motors have been out for considerably longer. I hope we get there soon. Good luck, I’m interested to see how it turns out. |
