Buddy of mine had both and he agrees with bm3 being the better choice of the two.

My buddy and his dog say thats not true.

Real talk tho that consistency line is whatever. Go look at drews 1/2 mike runs and let me know where its lacking consistency. He has burbles too

Why do you diss the ability to run e85 like its a bad thing. Thats a huge selling point for those of us that have it local. Im sure there will be a ton of praise once they release an OTS ethanol mix map for bm3.

I like bm3 and think its the best platform out there. I just wish there wasnt all this warranty flag smoke.

Not dissing the ability to run e85. I'm gonna be upgrading to that map soon too I was just going by what the people who have experienced both have told me.

Ran against an M4 with JB4 and full bolt-ons (DPs, intake, and straight-pipes), pulled a couple of car lengths against him with my M3 running on an OTS map and DPs only.

Yr M3 with Bm3 OTS map is for sure faster than a M4 JB4 Map 2, reason is as simple as the Bm3 OTS runs more boost compare to a JB4 map 2.
Just give that M4 a switch to Map 6 with more boost dial in & the OTS M3 will be few cars Length behind him.

This post hurts my brain. Are you aware that stage 2 bm3 targets less boost than jb4 map 2?

Not true, and I've logged both. The bm3 OTS maxes around 23, with JB4 it was making 25, spiking as high as 27. Map 5 is faster than Map 2 in a roll race as well.

Did u had direct comparison map 5 vs map 2 to state that map 5 is faster ? The torq map 2 makes is 80+lbs more then map 5 .. map 5 have around 10whp more on top end for like 1k rpm ..

Yes. I'm the one who tested it. http://f80.bimmerpost.com/forums/sho....php?t=1245843

In a race Map 2 has a superior power band only for the jump. Once you're over 6000rpm you're never going back under, and Map 5 has better top end.

I personally liked flash better then all piggys I had. With the flash, it didn't seem like the car was fighting itself to figure out what to boost too...it was just there. My drag times also were more consistent, where the jb4 would end up running slower after 8+ runs (to the point where stock 335s could run faster), the flash ran 16 all within .1/.2 of each other.

My experience though. I'm sure someone will chime in to say my post is garbage because their friends friend who is a technician said his boss said I'm wrong.

I would not say ridiculous, dollar for dollar you get more out of Stage 1 for sure. Not many people are interested in data logging or whatever other gizmos are included...most want to set it and forget it. Add to it the ease of removing a piggy back if you need to visit the dealer. What is the cost of BM3 out the door anyway?

[F80R]

There's no doubt that flash tune is the way to go .. but the warranty is the concern here .. specially when some one leasing the car with flash being detected and then ur car flagged and then issues returning the car etc ... it's not worth it .. we understand that if something catastrophic happens with your engine with JB4 or flash tune Bmw will know u were tuned .. but JB4 is still safer way to go .. as long as u remove it before dealer visits for oil change or small issues you safe ..

Blue pill or the red pill. All void warranty but one is faster than the other and for good reason. What do you do on the piggy, crank boost? Motor is staaaarving for octane and knocking along the way amd it shows in this vid. More mods and crushed same car and octane. Please no contest. Piggies are cool but only until flash takes over.

That's a bald statement.. when u data log you can clearly see how the engine runs and if there is knock or not .. afcorse if you'll be running map 7 on 93 oct there will be knock and shit .. if you data log and see how ur car run on map 1,2,5 and you can chose your map for your octane and be as safe as flash tune .. JB4 been there for years .. and it's a perfectly safe solution .. it works well .. yea it's not as smooth or consistent as flash .. but it gets the job done as safely as flash .. with more flexibility ..

I logged both too, Jb4 map 2 only run 21-22psi whereas Bm3 OTS run 22-23psi.

Im ready. I run 5.5 gallons of e85 per tank. Which Wannagofast do you want to meet at Atlanta or Charlotte?

My map2 with e85 hardly hits 21lb of boost max. Usually 19-20.

Bm3 is cool man but this post is delusional. I definitely never run out of fuel and have 0 timing pulls. I bet my motor is less starving from octane then yours since Im running 5.5 e85 and the rest 93.

Something isn't right because map 2 is usually always around 24-25 with higher spikes.

Naa. Map2 log from my car running 5 gals of e85. Not even close to 24-25lb. Those are map7 boost levels.

And I have logs showing 24-25 on map 2 with 93oct on my vehicle. This was with catless downpipes, AA catback, Max Psi intakes, BMS chargepipes. What mods are you running?

Map 2 is additive. Adds 6psi peak (with a taper down at higher rpm) to the DME boost target. With the stock flash the DME target will change based on conditions like IAT's, etc. On a hot day with my stock ZCP flash I saw at most ~23psi on map 2.

JB4 only controls boost and additives, which is great, but a DME flash can affect SO much more and has much more potential to make reliable power. I have both, JB4 (for boost and meth control) and BM3 backend flash. Love having both!

Catless downpipes and BMC drop in filters. AA cat-back increases back-pressure over my setup but not sure how that would change boost targets.

Yeah to get 24-25psi on map2 the DME would have to be targeting 18-19psi in the midrange.
