The only major component you have different from my setup is the PR 2.5. No idea if related to that or not, tho. EKP maybe?

I do have the upgraded Stage 2 EKP from ET3, so I think I’m good on that front

But yeah I don’t see anything out of the ordinary based on the logs either 🤔

You can try to do it one at a time and NOT change other mods at the same time, the goal is to minimize variance in case things get more complicated.

1. Fresh spark plugs, gapped to 0.022'' even with B58 conversion kit. It's enough for higher power applications, high ethanol applications, and Idling won't get affected unless you're above the 600-650whp range or running 30psi+. Eliminating the plug issue at the beginning is better than gapping down slowly while tuning the car and having trouble. You can re-open the gap to find the optimal gap later. It'll save a lot of time/labor for you.

2. Swap coils/connectors around, note them on paper/phone, and do logs to see if misfire codes move or just random misfire codes. If CEL, restart the engine, clear the codes, and do more logs to confirm.

3. Battery voltage check. Make sure it's healthy.

4. Turn on "MSV after pi" on MHD or "HPFP angle final" on BM3 to monitor HPFP duty cycle, 109* is the max effort of HPFPs. Theoretically, tuners can push it up to 126* (log won't show above 109) and injectors could gain a bit of flow, but they rarely do it except when trying to squeeze every drip of fueling/injectors, etc. Over-push stock injectors or keep them running max duty cycle increases the failure rate.

5. Our stock injectors will hit [...]

Thanks a lot for the writeup! I’ll go through the list and report my findings.

Right now I’m running NGK 97506 plugs gapped to 0.022”, so I’ll start by checking the battery and re-logging (while monitoring HPFP duty cycle).

Let us know how it goes. Halim just gave me a similar map as yours, so will see if it gives me issues and will post a log later today.

I'll ask him for the map to run it on N55+, I dunno if he'll share it with me.

Here’s three logs on the Stg 3 MM V2. On my phone, so haven’t reviewed them or compared to TUDMG

No issues on my setup, felt pretty strong. Will be curious to see how timing looks with the added boost.

Doubt VD is worth anything, hard to find flat roads around here. 295/35/18.

22-23psi all the way, initial boost hit 25psi peak causing your hpfp dipping 1200psi, be careful
If 22-23psi from 5k-6k. I think it's around 520whp-530whp. Timing is not suffering tho, 11.5degree at 6700rpm ish
From my experience, you probably will hit injectors limit very soon, They are still working well at the moment. The only way to test it is to rev higher, both 4th and 5th.

I’m Dorch Stage 1, so I guess we found that limitation…

Boost is higher, but timing is lower than the Stg 3 MM V1. I don’t know which approach is better.

IDK if I’m pushing that much power. In my Stg 3 E50 beta 494whp dyno run we were pushing similar boost, but timing was slightly higher. That said, timing and power would crack up a decent bit up top on that map, so I stopped running it.

Maybe this one is 490whp’ish with my TTE460. IDK.

Got my winter tires on still: https://www.tirerack.com/tires/conti...ct-dws-06-plus 295/35/18.

Altho, each of those runs were not on flat ground.

2017 M2, DCT, full tank of gas, no weight savings, 180lb driver.

ZM2 - can you post a log you actually dynod with? That way I can calibrate it to Dynojet numbers.

It going to be an apples and pears comparison - but they are both fruit so that has to account for something.

479whp log: https://www.bootmod3.net/log?id=6205...729b3a50870ec1
494whp log: https://www.bootmod3.net/log?id=6205...90c62156bfa6e3

While the 494whp log looks decent, you can see how quick power dropped up top, so I stuck with the 478whp tune, up until today while I'm trying out Stg 3 MM V2. So, I'm curious if you guys see much difference b/n my 494whp log and today's Stg 3 MM V2 logs?

No problem. Michelin Pilot Sport AS3+ 265/35/19. The virtual dynos I posted have the exact measured weight of the car and accounts for mods, occupants, cargo, and fuel.

Honestly - before I look at the logs, a guy like you really shouldn't be running this OTS tune. Your car is too nice - quality parts and well sorted, I would hate to see you blow it and abandon this platform. You've done some impressive stuff and while I don't care for your attitude at times, it's well researched and clearly was a significant investment of time and money.

You need a custom tune.

The issue here is what you're using your car for and what your needs are. You need to gain some efficiency somewhere. I think having a tuner who knows have to adjust valvetronic and cam timing is really valuable to unlocking additional power. It's not about knowing the maps - it's about actually understanding the concepts AND having first hand knowledge on what works on the track.

Right now, this tune is a MAXIMUM effort street tune, it's not made for what you need. The guys who run this on a street make youtube videos holding the phone vertically with burbles turned up to maximum. You're not those guys. While you might not care for my recommendation, I think you should speak to Bob at StageFP (or anyone) Because you deserve better than this.

I understand what the tune is and I wouldn't run it on track. It feels pretty damn quick on the street and that's where I'd use it.

For the track, this is the last tune I was running, likely ~460whp and quite a bit less boost: https://www.bootmod3.net/log?id=64ee...0b430837cdaf22. Altho, I was still hitting 250F coolant on a 45F day at the track, so guessing swapping the intercooler will have to be tried later this year.

Want to get more current track data first on these and lower power level maps to see what temps do.

Yeah, not sure what to say about this. IDK if it's the road elevation change that's throwing VD off, but I have many dyno's above these power levels and a 7.2s 100-200kph to back it up.

Obviously I haven't dyno'ed (or Draggy) these b/c just got them today, but they def don't feel down on power. This is one of the reasons I don't really care to use VD.

But do you have your dyno run files? I'm betting I'm comparing "uncorrected" VD numbers vs "corrected values" on the dynojet.

What FMIC are you running? I’ve run the same tune on track but never checked the temps so I’m curious. I have CSF.

For reference once I get my misfiring resolved, how much ethanol was in the tank when you got the 7.2?

Yeah I’m still a little skeptical about VD. Unless conditions are near perfect, my personal policy is to refrain from posting them unless it’s to get an idea of power delivery (not exact power/torque numbers)

Wagner Evo 3.

Take some logs at the track next time so you can check temps. Many variables at play that will impact coolant temps including ambient temp, grip levels, and how hard you're driving.

To give an idea, I was doing 1:20s on Summit Main and 1:28s on NJMP Thunderbolt on the current 2+ Multimap on RE-71RS's. I've added coilovers since my last visit to Summit, so I expect to be in the teens on fresh rubber.
