This is something I've been curious about. When you get the Dinan turbo you can also get the harness that allows the vehicle to work with it. Can you run software in addition to the turbo and harness?

I love how my car drives and looks. If I had to do it again, I'd pick up an M2 OG (and add the mods I did) over a competition in a heartbeat.

If you started from scratch knowing what you know now about the OG M2 what would be your ideal path? I am like you and prefer a linear powerband not the midrange shove then top end death

As I just said, if I had to choose between OG and Competition, I'd take the OG in a heartbeat and mod it the way I already did. OG is simply a better car in many ways and overall, which M2C could never be.

Got the TTE 550 turbo today.
Everything looks as it should and balance report included. I bought it through eBay from a guy that works with TTE. He currently has a 460 turbo up for sale too. I payed 2450 euro- for the complete turbo. Time to find a good installer now. Last edited by Rondavouz; 08-26-2018 at 07:28 AM.. |

How's the car as a daily drive with the upgrade? Also pardon my ignorance but are you on a MT or DCT?

Just so you know, my car has been dialed in, by Halim Cazimi no surprise. NOT the tuner I mentioned earlier.
From half a year testing, condition then 100F to now 65F, one thing I see for sure is my car has been stupidly easy to tune even just on pump gas. There is not a single map out of 30 or so thrown at it that it didn't handle well enough to accept (to normal standard) for long term use. Below is a log of a few repeated 3rd gear (no road for 4th unfortunately) pulls at just 16~17psi (below 100F of IAT). Keep in mind, boost is a hard thing to tell right about, because our load based DME adjust a lot to compensate for IAT. This map will see 18psi approaching 110F of IAT, so let it be. Some of you may notice the log I posted in summer where my car held up brilliantly at 18~19psi up top under even high IAT. Well, I decided to back off for the consistency pull after pull and 365 day everyday performance. What's interesting is that now my G Power map is even more conservative than my Dinan Turbo map that made 410whp last year. I pushed extremely hard on Shanghai F1 circuit on one of the early versions of below map (about the same aggression) as reported earlier. It was rock solid for two tank of gas and easily kill M4s on straight. http://www.bootmod3.net/log?id=5bc805cfd10b434f3ca873ea I will dyno it this weekend or some day next week.

Does anyone have a key component comparison between TE550 v PS2 v GPower ?

i’m new to this forum and thred. How much power are you making in your car now with The G power turbo. As I’m debating to do the same thing to my m2 or just buy the competition and upgrade that! |

See below overlay of GP500 and PS2, same day same dyno machine. 5th gear runs. The ambient is 22C/72F. RON98. No ethanol, no additives.
GP500 was on Halim's custom map that's seeing 16+psi at 90F of IAT. PS2 is doing 15-16psi on BM3 OTS STG2. BTW, above two maps are our track map. From track day datalog in the past few months, I see no benefit at all from going any more aggressive ON TRACK. In addition, on the same day, Dinan turbo showed 390+whp@17+psi on JB4 custom map 6 + BM3 STG2 as BEF, pretty much maxed out. Interesting STG2 turbos are using less boost maps than STG1 - how I influence people LOL Need to mention this dyno reads super low, seemingly 15-20whp lower than USA numbers. To put things in perspective - There is no M4 base seeing 400+ and the best for ZCP is 410+. My Dinan turbo last year maxed out by custom flash did 410+whp on a freezing cold day (definitely would struggle a little on 70+F day). Also see spool difference. To achieve 400lbft on 5th gear, PS2 needs 3000rpm, GP500 2700 rpm, stock/STG1 turbo would be 2500rpm. Keep in mind at lower gears spool difference would be significantly more.

So if you’re pushing 425WHP At the crank/flywheel you have 500bhp give or take That’s with a 15% drivetrain loss. Does that sound correct or am I wrong I’m new to all of this so sorry if this sounds stupid!! Just seems like it’s going to be cheaper to buy the M2 competition and remap it Then going through the hassle of changing the turbo as well as other parts. Upside to the old M2 is lighter Upside to the new M2 competition easier to have more power And front parking sensors Lol Last edited by Ramon89; 11-15-2018 at 03:34 AM.. |

M2 has been the all time most inconsistent turbocharged BMW there ever is, thanks to the fact that factory flash already pushes a little out of its turbo efficiency zone, making it highly sensitive to octane/IAT. As a result, USA Dynojet has seen a range of 320~355whp reported from 2016 summer to early 2018. I believe on a cool day and 93OCT, M2 is a 350whp car USA number. In my case, under perfect condition and good pump gas, stock M2 is 330+whp, M4 base 390, ZCP 410. That's how my dyno reads 15~20whp lower than USA. Stock M2 competition would be 380whp on my dyno at best. With USA numbers, you'll see M2 N55 doing 430~440whp from STG2 turbo on pump gas tune no issue. And S55 would be doing 450/470whp from BM3 STG1/2 tune. As for M2 mod vs. M2 competition. My opinion is this https://f87.bimmerpost.com/forums/sh....php?t=1551866

Guys, Halim surprised me with a new map delivered on Christmas that I only got to dyno last week.
The map dialed back low down boost a little and add a little more at middle and top end. Still we're happy at 17psi range, and the dyno result was impressive both in value and in power shape that is similar to my STG1 turbo (18psi) but shifted up a lot. The motor is super happy, evidenced by the maxed out ignition timing all the time and rock solid fuel pressure that's no dip at all, leaving plenty headroom for summer and track use. And it ran so cool that the dyno pulls saw IAT decreased at the end of pull from the start. Keep in mind that's 5th gear pulls with nowhere near as much air flow as doing 150mph in real world. I was about to post the graph. But finally decided to further tweak the torque shape and will dyno again and post. What's more is that the drivability is BEYOND stock smooth. I base my conclusion on back to back to back to back to....to back drive with completely stock car in extremely heavy traffic (think New York downtown traffic) and highway. Huge thanks to Halim!
