I have a Dinan tune stage 2 (piggyback) on my n55 435 and I just got the BM3. I want to remove the Dinan and flash Bm3 instead but the thing is I don't have a torx 47 at the moment to physically remove the tune. I was thinking of maybe switching to Base map on the dinan on my phone (which means it's disabled) and run bm3 until i get the t47 and remove it, what do you guys think?
on the Dinan app, i can switch between base (disabled), stage 1 & stage 2.

if the Dinan tune is disabled isn't it the same as if it was removed?
I'm just too excited to try the bm3 and don't wait to wait to get a T47

Make sure the battery is disconnected first and just snip the wire right at the torx. I disconnected the dinan tuner at home and realized that I didn't have a torx after everything was disconnected when I switched from the dinan to bm3. A little ring crimp terminal won't harm anything being left on

Youre gonna be so much happier

No, it's not the same as being removed. It's still there. So, remove it physically. Someone has tried to do this before. Or, you can try it and let us know how it goes.

I switched my jb4 to map 0 and unplugged the obd connection when I flashed bm3. Everything worked fine.

Thanks for your input,

I just watched a video from Bryan (Kies Motorsports) and he says that if you have a jb4 connected you can just put it in map0 (disabled) so I guess it's fine disabling the dinan and keeping it connected it for now.

I will add my feedback about bith 2 tunes in the next couple of days after trying the bm3

I personally wouldn't risk leaving it in with a separate tune being put to use.
However, I had no way of disabling the piggyback tuner since it didn't come with an app, that's why I just cut the power wire at the terminal when I realized I didn't have a T47 and removed the entire tuner before going bm3. Having a little crimp terminal that's left in there for another day feels a lot less invasive than having a unit that is breaking a connection between a bunch of different harnesses inside my engine and being told not to transmit anything. What if it doesn't pass through the rest of the normal OEM data that is meant to be going through? What if for some reason it resets and starts broadcasting and adds another 4-6PSI to the system when I'm WOT? Must be the e.eng. in me

Ok, so I switched to Base on Dinan and I did a few pulls to verify that it's disconnected then flashed the BM3 and everything is working fine.
I love the burbles with the BM3 as for power, I feel it's a bit more powerful than Dinan stage 2 but not a lot but you definitely feel the difference. If it wasn't for the added burbles I probably wouldn't have done it, but again for the price, increase in power + burbles, very much worth it!

I also have the Dinan stage 2 and bootmod3. I just put my dinan to 0 and sofar everything is working fine. I have not have the time to unplug the dinan.

Its significant as otherwise 10-15whp you wouldn’t feel. You probably gained At least 20-25 if not more

Hmmm....there's an M235 6MT dynojet plot showing 383whp and 394wtq with the Dinan Stage 2 and downpipe and the run being in quite hot weather no less. I have a hard time seeing a BM3 Stage 2 exceeding those numbers, by much, as every BM3 Stage 2 dyno I've seen isn't much higher, if at all.

There are 450whp dynos on bm3 on ewg cars 400 on pump even. That Dinan graph even though less is like a major glory run if you search around

[JaredG_F30]

I put down 381 whp, 429 wtq on BM3 stage 2 with shitty California 91 octane two yrs ago, several map revisions earlier than current. I'm in NC now with 93 octane and E85. Installing meth this weekend then plan to dyno sometime before the end of the yr with meth and the stage 2 E30 map. Hoping to get into the 400+ whp club.

450whp with ethanol/meth, sure. Sure, there are BM3 cars pushing 400whp, we all know that's pushing the limits of the fuel pump and most BM3 Stage 2 N55s are showing 370-390whp.

I don't believe the M235 Dinan Stage 2 run to be a "glory" run at all. Posted below is an M235 Dinan Stage 1 Dynojet run in 90 degree weather pulling 340whp/365wtq with no other mods. It's totally reasonable to think that a Dinan Stage 2 EWG N55 with a DP should pull 380+whp and 390+wtq as linked above. Both of these N55s should show slightly higher numbers in cooler and denser air.

Sure, you can get slightly more HP and a bit more torque from a flash tune and even a JB4. However, much of that gained torque is below 4,000rpms. That doesn't do you a whole lot of good during an all out run because all shifts are landing at 5,000+rpms. Only for a fraction of a second in 1st does the extra torque help and likely makes you slower as it can induce traction issues.

The old school Dinan piggyback is laughably expensive, but they did go to great lengths to make the power linear rather than a sledge hammer in the low end and having power cut issues on shifts because of momentary boost spikes (i.e., JB4s and other piggybacks). For performance driving, you want linear power and not a massive surge in power that overwhelms the tires with little notice. Dinan definitely focused on driveability above all out power.

I think the flash tunes are a great option, but I also don't feel like they are remotely as "smooth" in power delivery as many originally proclaim given the number of issues reported in power delivery hiccups on this forum, the 2 series forum, and the M2 forum. Perhaps it's because many of those flash tune owners came for JB4s. BM3 is constantly revising their maps for better and smooth power delivery and in some cases, has reduced power/boost because it turned out to be bit too much for certain cars/DMEs. I feel like BM3 is using it's users as the guinea pigs. MHD seems to take a more conservative approach to power delivery and driveability much like Dinan and BM3 has become the BMS of the flash tuners where all out power is the goal.....because they know that's what most want above all other things.

I did something stupid the other day. First I put the Dinan tune in Base map (disconnected) and used BM3 for about 2-3 weeks with no problems.
I did not remove the Dinan because I didn't have the right Torx bit to disconnect the positive. Then a few days ago, I got the torx bit at night and disconnected the positive but didn't feel like removeing the dinan at the time so left it connected but without power thinking it disconnected in the first place. Next day I get a driveterrain malfunction and the car drove like shit, rpm was high , car wouldn't go faster than 80km/hr. later on I figured out what i did wrong. I should've removed the didnan fully and plugged back the 2 original sensors back in to the dme because the dinan was with no power it was not sending the signal back to the dme. Lesson learned!

Were there any resulting damages?

You probably didnt notice but the guy above you resurrected this thread from 2019, probably just trying to get his post count up
