How does the BMS Stage 1 tune affect the smoothness of power delivery? Does power delivery remain like stock? I have a 435 and I'm really hoping to retain the stock power delivery dynamics, just with more power overall.

Stage1 is very smooth. Especially with the EWG cars!

I think you will be surprised with how smooth power delivery is for a piggyback.

This is a question ive been wanting to work out - all the stage 1 tunes deliver about the same power - would something with more sensors connect like the Active8 tune deliver power smoother than BMS stage 1?

I really want a tune thats OEM+ but there is a lot of conflicting information making it hard to decide on one...

Thanks

In theory yes the Active Autowerke should deliver power smoother. In reality, difference is negligible at only + 3.5 psi
Some people are more sensitive than others
If you get them from the right vendor, they are both offered with money back guarantee, give them a try and pick the one you like most.

It has very noticeable hesitancy that i find pretty irritating

If you're looking for stock like smoothness only a ECU tune will achieve that. Plus you get tons more power.

Very true as I went from bms stage 1 then jb4. My flash from GSR is way more smooth and more power. Can't beat the price of the jb though.

I went from BMS stage 1 to GSR as well. Yeah its cheaper but well worth it IMO.

Guys I have a question, I have a 435i with the MPPK and MPE, and will the stage 1 BMS tune override the MPPK? and can it remove CEL warnings from installing a downpipe? If it doesn't, what catless downpipe is available in the market that doesn't cause any engine lights?

Jb/JB4 is a piggyback , PPK is a flash tune. Jb/JB4 will control boost, the flash tune will control everything else.

JB stage 1 will not delete codes, only the Jb4 will delete codes.

Or you can get the BMS f chassis can flap module and delete the codes manually every 50 - 100 miles.

I also notice that power does not come on as smooth as stock with mppk. It's a bit annoying at times as I feel the car hesitate, almost like turbo lag.

However when it does hit, it puts a huge smile and I almost forget about it....almost. But def best bang for the buck when it comes to fun factor and extra power.

Flash tune is always smoother than a piggyback ( it also costs $2000 more).

That being said the JB/JB4 is one of the best piggybacks i have seen in terms of power delivery.

Yes you cant beat the bang for the buck factor and in addition all the features it has, logging, map switch on the fly, race fuel E85, can flap is a must . Some people love piggy backs some dont. And it will have its good days and bad, sometimes you experience the lag or lack of instant power and other times it runs like a raped ape lol

Unless you're referring to a EGW car MPPK maybe, but even those can be had around $1300-1400 dollars.

But as far as ECU flash goes its nowhere near $2000 dollars more. You can say yes its easily double then for example a JB4.

My JB4 with OBD2 and data cable was around $500 bucks.
GSR ECU flash =$800 Group Buy
Enzo flash =$1095 Group Buy

Some people love JB4 some opt for ECU flash..just good to have options. Just glad we can tune these cars properly.

Shit take a look at an AUDI ecu flash those run for well over 2k So BMW ecu flash is a bit of a bargain comparing.

The user is comparing MPPK to JB4 not some aftermarket flash. My reply was based on that. Sorry my original reply was not clear

Even if price was exactly the same, i would pick the JB4 over the MPPK ( or any other tuning solution). It offers more power, more features, more flexibility over any other tune available.

Cant disagree those aspects about JB4 and the great functions it has. I still use mine especially for the can flap and logging. As far as it offering more power that's very subjective tune for tune, but I do think the JB4 really shines with aftermarket turbos where not too many flash tuners have gone to yet and perfected it beacause of the torque load...

I have both and a flash is way better in terms of power and delivery to me. Its ALWAYS there ALWAYS. The throttle response is ridiculous over JB4, its way smoother refined, no jerking no hesitating and no drivetrain malfunction errors. Is a JB4 Map 2 or 5(using that as referance because i would say 90% of people run these stages and maps) faster then a ECU stage 2 car? Maybe, No, I dont know...No one has raced that I know of to solidify some sort of proof. I don't care about dyno #'s because they are just that #'s...

With that being said there are far more JB4 cars on the road and I know there is an 11 sec 1/4 M235i with a JB4 attached to it floating around here somewhere. I cant say the same for any ECU flash. Perhaps its too early, perhaps its not possible or perhaps not enough people with a flash around due to expense to take and spend enough time at the track and get better #'s. Maybe next year who knows.

So in conclusion I've had/have both, and they both offer things the other does not much of it is GOOD, and some bad. But at the end of the day everyone is different and will pick what they like better. What I really think does not even correlate to another user or car because to each his own..everyone will set up their car appropriately according to budget and preference anyway. Different strokes for different folks .

Well said..

Just remember the JB4 for EWG is completely different than the JB4 for pneumatic wastegates. The EWG version is much smoother due to the nature of how the electronic wastegates work.
