Silly question but did you update the app?

Yes, I had to go get my laptop. Can't use my phone because it doesn't have ethernet support 🙄

Thanks, I'll just use my laptop tonight. I guess the $150 wifi adapter is useless until I buy another $1000 phone.

If my car is pro tuned (custom flash) and I want to switch back to a BM3 tune do I have get the car flashed back to stock first or will the BM3 just overwrite the tune that is on there now? Common sense is telling me that it will just overwrite and be fine but just want to make sure before I brick the ecu or something like that.

itll overwrite.. just make sure you do the full flash and not the quick version

Could someone provide feedback on these logs? 2015 N55, BM3 OTS Stg1 93 w/G-Plus Stepped Intercooler

Symptoms.. no issues under WOT, but occasionally on city driving ~2000-2500 RPM with medium throttle, there is strange vibration sensation. I'm thinking thats the transfer case slipping.

I see knock is reported on 2 of 3, and timings don't look great. I also see the wastegate duty cycle is a bit high but boost pressure looks OK. Not sure if that's a sign of a boost leak or not. Sorry for the long logs -- autolog doesnt work for me half the time, so after the first pulls didnt record I just started early with manual recording.

I'm at 42k miles on the car, stock plugs and coils. Not sure if that's a good start, or if I should try adding 1-2 Gal e85 to each fill-up.

agree that your timing is not great, but it's also not terrible. i'd say acceptable. if you have the ots map pack, you could try and log the stage 1 91 oct tune for comparison.

wastegate behavior is a bit overactive at higher RPMs in some logs and i've seen this before on my own car. i don't think it's a boost leak, just the tune itself not perfectly dialed for your wastegate.

I would also try running the 91 map. You don't really want knock at WOT, full boost. Looks like your fuel just cant support the 93 map.

I did my plugs at 45k. Replace with stock plugs stock gap. No guarantee it will improve your timing, but they are essentially due anyways since your car is tuned.

Thanks for the responses both of you!

Is adding E85 an option, or not recommended for an OTS tune? I do have E85 available. Kinda a PITA to use two pumps every fill up, but maybe better than downgrading to a 91 tune

mixing E85 does help but at this point it would make more sense to just switch to an E85 map

[FloorThe4]

Does anyone know if there is a way for me to get through my inspection/emissions test with my XDI HPFP in BM3. This isn't a question about emissions like everyone else asks since I have a Fabspeed Cat however I can't get my head around if the car will pass running the bm3 tune (the cel override will not be checked in bm3 due to me having the cat). If i remove the tune it seems the xdi pump will not run and requires that check box for xdi.

Just trying to avoid having to remove the TMAP sensor and XDI pump just to go to inspections. Any help is appreciated. Thanks

Similar to what Mike said, you can add E85 but you you might as well switch to the ethanol map and give it a shot if you are going to mix. I tried mixing some E85 on the 91 map with our crappy 91 gas here in CA and i still couldnt get good timing. I ended up going to the E20 map (MHD) and have never looked back... Not only is it the most power but its the most consistent. Two pump is not a hassle at all. I've been doing it for over a year and after a few fillups its just the norm. If you are going to go that route you should get the E85 test kit to test your fuel and follow my mix table (or use an app) to determine the appropriate mixture. I've elaborated on this and posted my table in tons of the ethanol mix threads so look for one of those.

FWIW you probably would not even feel a difference between the 91 map and the 93 map, especially when you can't support the timing on the 93 map.

You're better off posting in one of the emissions threads. AFAIK PA does not check the DME software, just the emission monitors (and probably visual), but you should confirm with your state website and/or someone who has done the test there.

I'd rather not buy MHD after having BM3 for only a short while.. so I'll probably downgrade to the 91. Since its EWG I can't use the E30 BM3 tune.

But just to verify.. the OTS maps are capable of working with an E85 mix, if I try it before going to 91? I'm just concerned about the fuel flow... it does know it's being sent "weaker" fuel and therefore sends more? I hope that question makes sense.

Hey folks, would you be so kind to read my logs?
I have bm3 st2 93 ots map + xHP st3 (cp, dp, plumb back BOV, cold intake). Brand new sparks and coils and fresh oil, tank had 13 gl of 93 and 2 gl of E85 and it was about 315 mi to go. At the moment when recorded that log it was about 129 mi, I assume 40% of those 15 gl mixed.

My concern is about boost. At peak it has his 17 psi or so, but starts slowly, is not it? HPFP works as expected. Timings are pretty similar. Load significantly below but I do not know what is that about. Any ideas why my car with st2 93 run 0-60 4.95 as best? Thanks.

You're 2015 you should have EWG and wont have any problems running the bm3 stage 2 e30 tune

I didnt say anything about buying MHD? You can definitely run the BM3 ethanol map, not sure why you are saying you cant? They have maps for both EWG and PWG.

Yes, they work with an E85 mix, but it just relies on closed loop fueling to correct to the E85 in the tank. These cars don't have ethanol sensors stock so the car has no idea you are running more ethanol, it just uses the oxygen sensor to add additional fuel as needed to keep AFR in check. That's why you dont want to go more than 2, maybe 3 gallons max to an otherwise full tank.

I thought EWG could only handle E25? PWG can handle more?

You mentioned running the E20 MHD map, that's all. I only see E30 OTS maps on BM3.

How much you can actually handle in reality depends on a number of variables including how your particular car responds and atmospheric conditions (since BM3 is boost based tune). Their map is advertised as E30. You can start with an E30 mix (30% ethanol in the tank), datalog, and check your timing and HPFP pressure. If HPFP is crashing, reduce ethanol %.

Correct, MHD recommends/targets E20 because E30 is too close to the HPFP limit. The BM3 tunes typically push hardware further. I actually target a 30% ethanol mix on the E20 map for timing/fuel quality reasons, but its right at the HPFP limit.

PWG can "handle more" because they run less boost, so less air, but the same HPFP.

[GAB0]

Changing the subject somewhat.... I recently made the jump to XHP after using the BM3 transmission flash for 6 months or so. I genuinely thought I wouldn't notice much difference when I made the swap; I was wrong.

The improvements are very, very noticeable and I got a little over 2 mpg more. For those on the fence BM3 and XHP combined are a great combo.

Forgot to respond to this. Your concern is that the turbo is spooling slow? I would compare side by side with some other logs and see. Use the time parameter to compare.

The other thing i would comment on is that your IATs are quite high and you have a pretty massive IAT rise for a short pull over 3rd gear. Are you trying to run this map on a stock IC? You didnt list a IC in your mod list. In any case, your IC seems significantly undersized if you are running one. You should not be hitting 130F IATs by the end of 3rd gear. I don't know what you mean by "cold intake", but if its a open air filter, thats basically a hot air intake.

The load is basically irrelevant in BM3 because its not a load-based tune like stock/MHD.
