Thinking about adding the Dinan big turbo but I don't run the Dinan tune as I have BM3. Can BM3 tune take advantage of the big turbo or do you get the gains just with the bigger turbo while running stage 2 tune? Thanks!

My Dinan/BM3 thread shows me starting with the Stg 2 tune and working with PTF to get a Stg 2H tune with more power!

M-Supra has one, as well.

That's the path that I'll be taking along with a sport cat, intake tube charge pipes and FMIC.

[ZM2]

The only caveat to all this is my Stg 2H tune is with V5.5. I like the midrange on 5.7, so I have to send more logs to PTF to get a Stg 2H 5.7 map. Then, I’m putting on a sport cat in a cpl months and will send logs and try for a Stg 2H 5.7 V2 map.

The point of me saying all this is Halim only has so much time in a day, so you have to ask nicely and not for too much custom tune stuff.

Halim mentioned creating a Stg 2 Dinan turbo OTS tune, so maybe that is still coming.

Yessir!

coming.

Hard to ask nicely when he won't answer e-mails or is just so far behind.

I thought 5.6 and 5.7 were the same with the exception of fixing the burble stuff on 5.7?

Yup, my bad. I meant I’m on a 5.5 Stg 2H 93 map right now.

About to go reflash 5.7 and get some logs.

He likes logs. Send him some nice logs and you’ll get a response.

Nice! Is your custom tune available to others and if so how do you get it?

You can run Dinan turbo + BM3 upgraded turbo map

[M2C AW]

I’d like to do a turbo upgrade, but starting with FBO and Stage 2 93 tune, it appears the stage 1 Dinan Turbo would only net around 20 peak hp..making it a fairly pricey upgrade on an installed $$/ hp basis. May be better value going straight to Stage 2.

20WHP in peak, more in usable power under the curve.

Plus you’ll introduce lag and need a fueling upgrade to extract all the extra hp of a Stage 2 turbo, unless you take SeanWRT approach.

Same here and never got his response, very disappointed...

Halim can build you a custom map or you can run OTS "off the shelf" maps from BM3.

Guys you have to realize the fact that Halim as the BM3 master tuner is first the tuning/platform developer, then an enlisted custom tuner with BM3 platform.

He's responsible for ALL the tuning with the company and has to literally hand make each single map under PTF's name for ALL BMW F and G models. There're 10k+ global customers that need to know the maps they can download from cloud sever any time are safe and performing. It's a huge responsibility to take, imagine that.

Now is a critical timing for the BM3 as they're working on B58/B48 ECU, so are their competitors. Whoever enter the market first with well validated products win a huge part of market.

As a young tuning professional, he probably has more map to make and test than anyone else in the BMW's game every day given BM3's popularity. And he has to prioritize his tasks.

Use the OTS first please, V5.7 is pretty aggressive really. I'll say it's already stronger than the 'infamous' V5.3.

I seriously doubt FBO car on normal 93OCT can handle V5.7 when ambient is above 70F.

IMO, even stage one turbo can be taken full advantage of on pump gas with V5.7. I mean it.

Couple of questions for the guys smarter than me...
When running Stage 2 93 and summer ambients head upward, what would be the next logical step down flash for a FBO car on 93 for open track lapping ?
Stage 1 93 or..
Stage 2 91 ?
Next, when reviewing logs, what data am I looking for to see if current tune is too aggressive for current conditions ?

I would like to know this as well

I would think that if you see timing being pulled (retarded) the tune is too aggressive.

[ZM2]

I'm not an expert on this stuff, but I'll try to apply what I've learned from here.

If you're noticing high IATs and timing pull, the first thing I'd try is 100 octane race gas or octane booster. That will help prevent timing being pulled as IATs go up. It helps for consistent power, but doesn't solve the issue of heat soak on really hot track days.

If IATs are pushing into 120-130F, I'd drop to the Stage 2 91 map. That's more power than Stage 1 93, and it'll back off the timing advance and runs a richer mixture up top. I'm guessing that would be good enough on a hot track day, if you have a good IC.

[M2C AW]

Being the miserly sort, I’ll dial back the tune before trying the 100 octane route.
When the time comes, I’ll start with the stage 2 91 per your comments and see how that does.
Thanks for the input.
