What you really need to do, especially if you want to do an apples to apples comparison of this OTS map to your custom tune, is do 2-3 4th gear pulls on each, with some adaptation miles between each flash. The multi gear pulls are helpful sometimes, but not really for comparing tunes. You need the 4th gear logs so we can easily compare boost control and timing in particular. |

I've re-gapped my NGK plugs down from .027 to .024 to see if that helps timing, esp in upper range above 5700 RPM's. Seems am getting spark blowout from the increased boost. Will log later.
It does feel better up top in 4th gear from a pull I did on the way to work this AM, so hoping this does it or I'll get new plugs as these NGK's have about 20K on them, but they were in perfect shape. |

Some of the M2 DCT's are getting momentary boost spikes above 21psi, so I'm going to put my 3.5bar TMAP back in today just to make sure there are no issues with that. |

ha, we're always splitting hairs on spark plug gap, however, what if the real important matter was spark plug indexing?? suppose the spark plug that was removed, regapped, then reinstalled, was to a different torque thus different orientation which affects timing or spark blow out?! just spit balling here.
i'm guilty of it too. i had misfires with 1-step colder plugs at stock gap about .030, then i regapped to .022 and seems smoother!

No real change in the upper revs timing with the NGK plugs re-gapped down from .027 to .024. Suspect stock downpipe major flow restriction with so much boost up high about 21PSI... May have to get a high flow catted and an HPFP upgrade, but pressure is good up top.

Pwg numbers
I'm debating installing my Supra b58tu pump and running e50 on my pwg car cause it really won't make a difference the pwg turbo runs out of power at around 400whp

This map is strong and likes to FLOW! With a stock turbo you almost need a decat to get perfect timing while hitting boost targets. Even with my 300-cell HJS sport cat, Dinan turbo, and all supporting mods, small timing corrections creep in as IATs get >100F. Thanks to the half E85/half 93 mix, the corrections are much less than what I'd see on the Stg 2 93 map, but this map has way more power. I was out driving in the cooler weather yesterday, and I've never been happier with my car! Loads of low end torque, lots of power, and the smoothest and most linear power I've had to redline. Huge grins every time I hop in the car! Anyways, all of this means you have to relieve the bottlenecks to get clean timing under full boost thru the revs, and once you do so, there's no way in the world the stock HPFP can keep up with this map. |

Here's another log: https://www.bootmod3.net/log?id=5f99...0b430319a475d2
No changes except a fresh tank of half E85/93, change from aFe drop in filter back to OE paper (oil analysis showed too much dirt with the aFe), and 3.5bar TMAP installed. You can see I'm hitting 21.6psi at the beginning of the pulls, so I put in the 3.5bar TMAP and it resolved a few sputters I'd get when I would get close to the max of our OEM TMAP. Overall, this thing rips! It's working my Dinan turbo hard, and maintaining 20-20.5psi psi to redline. Loving it! |

I make mention of this because I noticed that stage 2 race gas was about 11 degrees and now the stage 2+ race gas is 13. My wmi is having trouble keeping up with 13 target https://www.bootmod3.net/log?id=5f95...729b52119f21a6

The E30 & Race Gas maps will have different timing targets, but I’ve also seen my max timing target in the 2+ OTS change in different logs, I’m guessing bc of ambient and IATs. |

As long as you have the correct fuel and enough fueling capability, whatever mods you have will determine how much power you get with these maps. In my case, my Dinan turbo is the bottleneck. My car is definitely pulling harder with the OTS vs the beta Stg 2+ E30 maps that I helped worked on with Halim. I dyno’ed ~430whp on a Dynojet then, so we’ll see in a few weeks how much that little Dinan is doing now! Last edited by ZM2; 10-28-2020 at 05:43 PM.. |

Here’s an M2 Stg 2+ Race Gas log from a buddy, if it helps: https://www.bootmod3.net/log?id=5f98...0b43028e1f9ed9
Targeting 21.2psi on the stock turbo, if you can believe that. He’s decat, so that’s helping a ton. |

designatedposter asked the same question regarding fuel: https://f87.bimmerpost.com/forums/sh...1766028&page=2 I'm not sure exactly what fuel he's using. And yeah, 20-21psi to redline on the stock turbo? Ridiculous. No doubt the decat is helping a lot with WDC and keeping boost levels up! |

figuring out using 3rd gear since that what Ive read to use for a manual but could you get him to do a full pull in 4th... cause I don't want to say anything until I see some more info... there is just no-way these numbers are right for whp... Boostane chart says I'll need 6.2 bottles per tank using 93octane @32oz per bottle @ $30each = $186 per tank.... lol... If I buy the 5 gallon container it will cost $124 per tank... and I still can get it from Amazon... lol... they even have a pump spout on Amazon for it... lol...
