You have the Dinan turbo installed right? I'm doing a very similar setup on my M2, except with a PS2.

Those Multimap numbers are on my TTE460--stock like spool with good power. The Dinan falls flat after 5500RPM (see chart below). In the new Stg 2+ E50 beta testing I have seen, stock/stage 1 turbos were hitting higher boost & and clean timing to redline, but it req E70+ to do so.

I tried E60+ on the Stg 2+ Multimap and Halim's modified Stg 2+ E50 beta for my setup, but my Dorch Stage 1 couldn't hang even with Dorch's updated HPFP tables. So, 490-495whp on E50 is the best the Dorch Stage 1 will do. If I had a Stage 2 pump, I might see 10-15whp more with E60+, but we're already starting to max out my TTE460 when it's above 485whp anyways.

I will say that I ran the Stg 2+ Multimap at the track over the weekend and the logs were absolutely beautiful. I had other non-tune related issues that kept me from running full tilt over the weekend, but from what I saw running Stg 2+ MM with my setup and just dumping in E30-50 into the tank from some fuel jugs and letting the tune adjust is a very strong/safe way to go at the track.

A guy in a Porche 911 Turbo with a license plate that read "630HP" was very surprised that I was hanging with him down the straight away and then he'd have to give me a point by and then I'd pull away from him in the corners. The reality is that I would get a better run out of the corner onto the straight and be in his draft so my car could just hang on, then he was a lazy braker and needed more driving skills for the corners, so I'd just pull away. Still was pretty gratifying tho! My top speed on the straight was 11mph higher this year with the added power (151mph vs 140mph), and I'm still rusty early on this year.

With your PS2 and the upcoming Stg 3 E50 OTS map, you'll make 530whp easy on E50.

Makes me want to order a PS1 and a HPFP and see what the limit of 93oct is.

Not much. Only like 405-410whp max. Octane is the limit in that setup, especially in summertime.

You really need ethanol or race gas to start to open up big gains on our cars. E40 got my Dinan and other stock turbo cars to 440-445whp, but you have to short shift at 6K to keep power levels up. Was still good enough for 7.6-7.7s 100-200kph tho!

My current setup is ~7.0s.

Very nice!

I have the same plan to bring some jugs of E85 with me as well - flexfuel is pretty awesome. I'm running the E40 on the stage 2+ E30 map currently (stock turbo, dorch stage 2, with halim dialing down the boost to 15-16 PSI at the top end). Timing looks good with the short pulls I've done on the street, but nothing on the track yet. I'll see how that goes - mostly concerned about cooling tbh, hopefully the E-mix cooling will be enough to offset the heat from increased timing and relatively low boost.

I do have a PS2 incoming, but with the long lead times, not sure when it'll arrive. Hopefully the Stage 2+ MM E50 map is out by then, definitely wanting to try that out with my new shiny turbo

recently got the dragy, now I wish I had DCT. I lose so much time shifting from 3rd - 4th, I am contemplating power shifting, but do not want to risk blowing my clutch or transmission. I estimate I lose about .4 seconds during my shifts. Corrected though, I am hitting the exact same number as you are with my 6MT, 7.44 seconds... this is running the stage 2+ E30 map, with pure stage 2 turbo, and E35 in the tank... wonder If I can improve my time with E50....

before getting the dragy, I was using the m performance drive analyser, and my times were lower... Dragy is a heartbreaker for sure, lol.

Yeah, tough to beat the DCT! I miss having a manual for weekend drives, but my car sees more track miles so I'll prob get something smaller, lighter, older, with a manual for weekend cruising.

The 2+ maps have always ran a little better with E40-50, even tho they're labeled E30. So, I'd def up your mix. Half E85/half 93 is an easy way to go.

Also, you may want to try the Stg 2+ Multimap. You'll note in my curves above that the Stg 2+ E30 map has some upper RPM boost control that limits some of the power. With the Multimap and timing scaling on E50, I'm holding 10-20whp more up top.

After I put my TTE460 on and before I started testing the new Dorch Stage 1 HPFP tables (that provide more flow), I ripped 7.23s & 7.24s 100-200 back to back runs, while my HPFP was having drop outs above 6k RPM! I don't have drop outs on the new Dorch S1 tables, so I think my car has a 6.9x 100-200 in it on the right day and right piece of pavement, which would be impressive considering I have no weight savings on the car, but I haven't put the Draggy up on the dash recently to try--just been enjoying driving her and hauling ass!

Hey everyone.

Thought I'd post up a Stg 2+ Multimap log that includes Stg 2+ E30-->93-->Flat Torque-->E30, all in the same log: https://www.bootmod3.net/log?id=62ca...729b6f82862fa8

I've switched between the maps before and felt the difference but hadn't logged them all together. Pretty cool to see the differences in boost and timing targets bn the maps, and associated changes in HPFP angle, MAF/RAF, WGDC, clutch torque, etc., just from a quick map switch via the steering wheel while driving!

I keep the Multimap in Stg 2+ E30 map by default, but it'll come in handy to quick switch to the 93 or flat torque maps when I'm letting someone new drive my car, or if I need to dial back power on a super-hot track day.

Also using a lower final drive in the M235i - so torque multiplication is lower and gears are longer.

How are you guys getting 16psi of boost!? I am consistently 33 to 35psi 🤨

Stage 2+ 93 octane stock turbo:

Something doesn’t seem right. That’s blow your turbo/engine territory.

It’s almost like the values are psia, not psig. I’d flash the regular Stg 2 93 and see what boost values are.

I checked my stock log and it’s 28.1. So like you said I guess the values are in psia? Not sure why though 🤨. If I take out the ambient pressure of 14.7 (I am basically at sea level) that would be 13.4 psi for stock and about 19 psi stage 2+. Does that sound more reasonable?

Seems a little low if it’s psia. Personally, I would send the log to BM3 and not drive the car until I hear back.

You could also try the stock tune to see what those values are. The flash take like 4min, tho, even if you don’t relock the DME.

Very odd all my logs (stock, Stage 2 93 and Stage 2+ 93) all show boost target off throttle as 14.7 while yours show 0. My ambient pressure is -0.1 and yours is 0. For some reason mine is definitely in psia.

So weird, haven’t seen this before. Curious what PTF says!

I am brand new to bm3 and the logs. Do I just contact customer support and attach log or is there a specific specific contact I should send it to? Thanks.

Even tho your logs say psig, there is a setting to switch between relative and absolute under the Datalog settings. Check if yours says absolute, and if so switch to relative.

That makes perfect sense. Mine says relative but I am going to toggle it back and forth and do a couple runs and see what happens. Thanks 🙏🏻

I had that same issue, I'm pretty sure this is what solved my problem.

** Not sure if you guys received the new update, but the F3x variant got a v7.3 update on 7-18-22. See attached. **

No updates yet for the M2 maps.
