Still running my stock turbo.

You won't know until you log it. Given that you are in SoCal, my hypothesis is that timing wont be very good with E27 because our 91 is so bad (I live relatively close to SSR). But the map technically says E30, so you could try with E27. Just do one pull if so and check timing. Or be a little patient / add some more E85 and get the E% up before driving hard and logging. Either way should be fine. I just wouldn't do a bunch of WOT on E27 until you log it.

Thanks Jeremy. I guess I got worried when I saw people talking about having much higher E content for this St2+E30 tune. Okay I'll run a log with my current E mix and see what comes up tonight. But I'm still leaning to going at LEAST E30 now that I have the DORCH 2. my stock HPFP could barely handle the E26~E27 mix on the regular ST2E30 lol. Given that, I'm excited to see what it can do

How do you like them? It was my first time going to them, but they had insanely good customer service so I'll probably be returning to them in the future. I live in LAC so it's pretty far, but worth the drive.

If you do log with E27 im interested to see what it looks like so post it up . But you can definitely handle way more. E40 might be a good target to try next time.

I've never been there because i do all my work/mods DIY lol, but i did read up on them on the forums and on independent reviews when i was considering having them do some work rather than doing it myself. Good to know you had a positive experience, ill keep that in mind.

Not a problem, I'll log at my current mix and get it posted! After my tanks empty I'll go E40 and make some comparisons.

Man you're saving TONS by making going all DIY. But I'd say it's nice to have a shop you can fall back on. If I go PS2, they're the guys I'll be going to without question. I'm a talker and ask A LOT of questions. These guys basically gave me the step by step with confidence. I hate shops that give me a price and a calendar day and that's it. I need every bit of detail before I can make a commitment, especially for something as expensive as this hobby of ours lol.

I did 2 pulls. The first one wasn't quite at the temp that I wanted, and pretty sure my tires weren't at temp either; felt wheel spin.

https://www.bootmod3.net/log?id=600a...3c0b46203ae758

This one was shortly after:
https://www.bootmod3.net/log?id=600a...0b43798f7a75fb

Timing was garbage on both. Fuel pump issues seem corrected with the Dorch HPFP. I also was at a slight incline on both, and I had a passenger. These logs were at a Mix of ~E25 on the Stage 2+E30.

I made a mistake in my last post, my previous fill before this one was at E27 for the regular E30 map. For reference (and curiosity):
https://www.bootmod3.net/log?id=5fca...90c6099b5148da

Dirving solo I definitely felt the power increase in my butt dyno. But with an extra 140 pound passenger at an incline, the Stage2+E30 still felt fast.

This weekend I'll be going for an E40 mix and doing logs. It'll be interesting to see the difference. I'll also be sure to be solo and a completely flat surface.

First log looks like you spun and had traction control. Then later on you had a knock and a bunch of timing pulled. Didnt look much further.

2nd log you went over boost target and it looks like you maxxed the MAP sensor for a while at 22.1 psi. Kindof surprising you made that much boost in 3rd gear (unless you are 6MT?). Especially because ambient pressure is -0.4. After about 5500 rpm your WGDC is bouncing near 100% so you are essentially maxing the turbo.

The main concern is the 2 knocks and the resulting timing corrections in the 2nd log. So yeah, you definitely need for ethanol. I would go 40 or 45% next time.

Yes sir, I'm 6MT. Is there any information from PTF that they changed some boost values to help squeeze more power for this tune? Or is this common in the 6MT's. I don't think I've ever had overboost up until running this new tune.

Yeah I'm actually gonna spend the rest of my gas now and fill up tonight. I saw all the timing issues and knew that my E content was way too low. But it'll be interesting to make a direct comparison with E40+.

Back to the drawing board, as usual. Thanks Jeremy! Always appreciate your second pair of eyes

I just looked back at MAKH5's log from the previous page for example and he doesnt have the same overboost and hold from 3k-4500 that you do, not does he hold boost the same after that. Your boost control looks better overall, but he did log in 3rd with a 8AT. Also he had a throttle closure from his overboost but you didnt. Tune version looks the same. I would need to look back at more logs, but your boost just stood out as a little higher than what i remember, not necessarily in a bad way. I'm sure it felt fast lol, and will be even faster with more timing.

Most of the BM3 tunes overboost for the first 1k rpm or so, so its not abnormal. If you look back at your stage 2 log, it has the same overboost behavior, albeit less boost.

Once you get a clean 4th gear pull with stage 2+ on a flat road with no passenger, you should compare it to your stage 2 log in virtual dyno assuming the no passenger and flat road were the same across both. Should have interesting results.

Was it the TMAP sensor in the chargepipe that maxed out or the MAP sensor in the intake manifold? They are the same part numbers, just placed in different locations on the engine.

I'm unclear on when it's a good idea to upgrade one or both of them from the 2.5 bar to the 3.5 bar sensor. I've been told that if either is upgraded it should be the TMAP sensor in the chargepipe.

I bought a 3.5 bar sensor. The VDO version is about $62 at FCP Euro.

I thinking that when I install a Dorch Stage1 HPFP and the BootMod3 Stage2+ E30, then I'll go with the 3.5 bar TMAP sensor at the same time.

You just need to upgrade the tmap (charge pipe).

When I was testing this map out for Halim we added the 3.5 bar tmap to help deal with the initial over boost most guys see. IMO I think the tmap should be part of the required parts to run this map. The car doesn’t like over boosting on the oem tmap.

I know a few guys have got a tweaked map from Halim with better boost control, this may be part of the latest updates

[JKen_0115]

I can't agree more with Daleb. I did upgrade TMAP sensor along with STG1 pump and STG2+ map, it worked out great but I had the boost control issue with OTS map. Then Halim took care the situation via another map. The 5.9 map may have addressed this issue.

Highly recommend to get all of three pieces together. ZM2 and Daleb are the guys to move this great upgrade along.....Great job!

A proper log would be better for us to look over. 3rd gear if your MT or 4th gear if your AT starting at 2500 rpms all the way until 6500.

I think you missed the log link in my F87 forum post that has several 3-4-5 gear pulls.

Timing in 3rd gear is all over from about 4800 rpms but then all good in the rest of the gears. Fuel trims dip lowest I've seen for BM3 but thats not necessarily bad. Amazing how there is barely any change in IAT's. I need to switch to a Wagner comp 3 asap!! I dont see any available for the f30's though.

Yeah, they don't even make Evo3's for M2's. Had to buy the one for the M235i and make a few custom adjustments. Great IC tho.

I may have been getting a tiny bit of wheel slip in 3rd, not sure, but I plan on upping from ~E40-45 to E47 for my next tank of fuel to help out. Will also give starting in 4th gear a shot.

He maxed out both in the log - MAP (which is intake manifold) and Boost (pre-throttle), which is charge pipe.

I have heard the same thing that you only need to upgrade the charge pipe one... but that is the logic behind that? The one in the intake manifold is the one that is actually measuring the pressure after the TB that the engine is seeing. The one on the CP can spike higher if you get throttle closures, yes, but it does not necessarily represent the boost the engine is seeing if throttle isnt open 100%.

I double checked and it looks like BM3 had an update on 1/19, SSR flashed me on 1/20, so the tune should be up to date. Like you said, these instances with BM3's boost control are the norm with their tunes. Thanks for giving me peace of mind for the boost lmao.

I decided to go with an E45 blend this morning lol! Once the roads are dry I'll be running some logs. Absolutely no passenger or incline either lmao! Did you mean a 3rd gear pull tho? You mentioned 4th gear. Just double checking because I've never done a 4th gear pull! ALso, I've never used virtual dyno, nor did I know it was a thing. I'll have to look into it, cuz I'd love to make comparisons.

Thanks again, Jeremy!
