way too much e85 in the tank on the last one..

I never had an issue with boost of fuel pressure.. looks like I may spend the money and switch tuners :/
Lol... they are not that bad... add 1/2 gallon 93 to a full tank to start..... adjust accordingly of course...do quick pull like you just did... look at fuel pressure... add if neccessary... timing.... one ... it's hard to get clean timing on pulls like this... Do a fourth gear pull to tell a better story...

gonna flash back to the cjordan map tomorrow and log and see what happens
Also, when I would switch bn BM3 OTS and CJ custom I would have to do Full flash with Unlock or I’d have HPFP issue bc the tunes use different tables. Quick flash wouldn’t fully overwrite. Super annoying.

Maybe this is your issue?

there is a ton of e85 in the tank on that last run. it was like an e60 mix, doesn't make sense.

Yeah timing here isnt great. Hard to tell boost control because you did a multi gear pull.

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.

I went the other way. Started at 0.020" bc of some ppl's recommendation, had little misfires, went to 0.026" and it's working great.

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

Your HPFP is crashing as early as 3500 rpm and continues to dip throughout the entire rest of the pull. Timing looks OK but you start to see some corrections in the upper RPM. For some reason your boost target also slowly increases which differs from the other logs. You let off before 6k rpm, but WGDC was already climbing rapidly. Adding a DP should help you sustain higher boost but will probably make your HPFP crash more.

I believe it was determined that you are not supposed to run that pump on a N55 because it can cause damage to the pump/engine. I would read the HPFP thread.

Agreed on all this. And ctt300, I still think it's nuts you're trying this map without an HPFP or DP, but it's all good data for the rest of us to see...

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!

You have an M2 right? I'm wondering if the timing target is lower than the regular n55 ewg tune. For instance, at 6000rpm your timing is about 11, whereas my n55 ewg stage 2+ race gas is closer to 13.

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

Yup, M2. As far as I know there’s no difference bn the M2 and N55 EWG Stg 2+ maps. They’re made to leverage the new HPFP’s and make all the power your supporting mods will allow.

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.

IIRC the exhaust manifolds are different and the crank as well

I’m referencing the OTS Stg 2+ maps. I believe they’re the same for M2 and N55 EWG.

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!

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.

That M2 must be FLYING! What gas was used? I had no idea 20psi redline was even possible on stock turbo!!!

It's Daleb car, who also helped with Stg 2 Race Gas 5.7 back in the day and the new Stg 2+ E30 and Stg 2+ Race Gas maps. He knows his stuff!

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!

I'm assuming.... manual... 3.46 final drive... 18" rims... 3450curbweight?... if so... very very impressive...stock HPFP????... if so forget the HPFP and using "E85"... what octane is race gas.. 110?... wonder how much Boostane I'll need... lol.... Boostane is good up to 116 octane...

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...
