Yup.. I got the older style hpfp so only option is Helix or port injection. So I had to invert the cables for 3.5bar tmap to work. No bashing but almost 40 bucks for a cable from BMS is a rip off.

BMW5sport got a brand new Fuel it port injection kit he might want to get rid of just in case anyone might be interested.

Too expensive plus I don't want to install JB4 tbh. If I really wanted to do anything I would go straight meth Instead and run 93 octane in the tank. But I hear bad stories of pump failing or lines leaking.

You need the manifold to support it unless you got the rail that goes in between. You need the JB4 and a hobs switch?

NICE! I love that movie. And yea, that sucks.

BMWDoubles, your log looks really good. Your boost curve looks better than mine. What are you looking to achieve with your tune? You don't log manifold actual boost pressure? Are you able to run full E85 with the Helix?

I can run full e85 but it runs better on e50 in my opinion. My fuel module did go bad but in all fairness it has never been changed. However, it might be due to the e50 tune. It's an unproven theroy but Showtime can tell you about his fuel module debacles. The goal is to clear 500whp.

Do you have the final tune on the car yet? If so, are you going to do a dyno pull anytime soon? Or are you doing the final tune ON a dyno?

I thought I blew my motor last night. Was trying to do a 1/4 mile run when it felt like the car was backfiring and not accelerating. Just when I was just looking at used motors and cost to rebuild a motor before the run! Even with that, I managed a 11.99 1/4 @ 121 mph according to Dragy. Anyone get these codes?

- DME active codes -
122108 - Blow-off valve: Jammed closed.
152508 - Super-knocking, cylinder 5: Injection switch-off.
152518 - Super-knocking, cylinder 5: permanent injection deactivation.
152D08 - Super-knocking: Injection switch-off.
213601 - Power management: Standby current violation.

- DME shadow (inactive) codes -
231501 - Fault entry: Send buffer full.

Another issue I have is 6 gear feels like there is no power. Like there is some kind of limiter kicking in. I have XHP stage 2 flashed. Anyone experienced this on their 8AT?

[BimmerHausPerformance]

wow, not just knock freaking SUPER KNOCK.

Have you change it to the EKPM2?

[PepMo]

Yeah SUPER geez. I crapped my pants on that one.

I got that error code when my sparkplug had a crack in it. Would run fine but when doing WOT car would feel like backfire as you mentioned.

[Bmwdoubles_]

Yeah super knock is not good. How's your cooling? Super knock can be a lot of things.

In regards to dyno not sure if I'm going to get a final tune, meaning not sure what I am going to do with the car at this point.

I put the flywheel and clutch back to stock and it feels great on stock. The spec 2 clutch is trashed. I believe it has to do with fitment.

I know people don't want to hear this but the N55 is not the best tuning platform and what's more is a F10 N55 is even harder to tune than other BMW platform. I'm not saying you can have a fun fast car, just saying a tuned F10 N55 is not going to be as fast as a similarly tuned F30 N55. Even if you get your F10 to be faster than an F30 you need to be ready for repair costs. I guess that applies to any tuned car, but a mildly tuned F10 N55 will not cause you those headaches.

Right now I'm running the OTS MHD PS2 95oct tune. I'll datalog it and see what it's making.

[PepMo]

You are right Doubles. I'm just trying to work out the bugs at this point and hopefully get to 550 whp reliably. But for now, it feels crazy fast already. How do you get 95 OCT? Mixing 91 with E85?

I got the BPM4 fuel module by the way. Not sure if I needed it.

[PepMo]

My IAT is usually 30 degrees above ambient on long pulls. My IAT got up to 104 on that 1/4 run. Oil 212, colant 210. I have the wagner competition FMIC.

I'm not sure if F10, 550whp and reliability go together. Maybe so with the upgraded file module and an 8AT, maybe. I chewed through my spec 2 and SMF on my 6MT, killed a fuel module, numerous other seals and belts. I think for reliability 425-450 whp could be reliable. New goal for me is that 450whp 450 wtq number now which I've obtained. I think that's the edge before it's frequent maintenance city.

Don't let my issues dissuade you or anyone. I have a 2011 manual with a e style hpfp. My problems are unique.

Yeah I'm thinking about dialing everything back down. I think 500whp on the F10 is safe because that's what I'v been making for months but did not realize it before the Dyno run. Since the dyno, I've been pushing tuner for more and more. I can feel more power and torque now on single gear pulls, but drive-ability and smoothness goes out the window under normal driving. I guess we will all have to just wait and see what $howtimes makes with his car.

made 580hp with my car. But keep in mind i changed EVERYTHING, i mean EVERYTHING maintenece wise in the process of doing that but the mounts and alternator belt which right now is getting done. All my fluids were changed to Motul. All my fuel injectors. I use M3 sparkplugs which get changed every 3k. Oil change every 3k. My wires are MSD. Changed diff mounts, transfer case mounts, front axles, all suspension bushings, control arms, sways. Cam, Crank sensors. Vanos Solenoids. Probally the only thing left is to change my struts to bilstein. Word of advice. If anyone thinks they are going to break 550hp without changing shit, your going to have a rude awakening.

Excellent post brother. 550 whp is possible, but the path to get there is not the same as other BMW platforms. Something else to keep in mind is our blocks are open deck not as reinforced as N54 or B58s. I haven't seen this problem yet which is the S65 crank hub problem on the N55. Throw enough power at a N55 and we'll soon find out.
