These mods should provide more power no doubt but I'm skeptical.
why BS man, I know someone on F30 group on fb that installed Meth kit but never met him in person, I have to be ready for a race if I met him lol

and here we have the same problem as Seraphblade@sg my car cost around $80 k and comes with a 17" rims without comfort access, HUD or even adaptive lights

We have a workshop that brings in another taiwanese charge pipe which is not threadstone and the build is similar to ER's. The meth was installed by B*** M**********, (OEM is BMS). Only thing we are not on race gas. But this shows the potential of their build.

I have already acknowledged that my knowledge is limited and that the info on the forum is limited as well. There isn't much forums to start with in the first place. The cracking of the ECU was already around for a while, just that proof were limited and no one were willing to try as they were not Dinan or the more established brands.


On a separate note, cars here in sg are expensive and u shld know that since u work for a facility with links here. The 328i is around 245k sgd. which is around 170k usd (at the current exchange rate) the 335 is at 290k. And the m3 is at 420k (all sgd). Therefore for such a market, it makes sense to do more to the car then get a better car.

To make things worst, our cars are only for 10 years, we need to make a 50% cash downpayment and the bank loan for the other 50% has to be paid within 5 years.
I would love to checkout the workshops you have mentioned here, can you PM me that information? I am leery on the power the n20 can handle but am comfortable where I am at now. This is the reason I haven't gone with meth and the turbo upgrade. I understand every enthusiast isn't on a forum but would love to get detailed info on these builds. Even my next trip over to SG it would be awesome to meet these guys.

Totally understand the cost of items in other country's. SG being the most expensive city and the fact that gum is illegal has always blown me away, lol.

I call BS because there is no proof. With what was stated above, depending on the ratio of meth this addition could very well be less of a power addition than me running 50/50 e85. In-turn creating less power, even with the upgraded turbo internals.

And for the turbo upgrade:

From the developer's facebook post

https://www.facebook.com/HexonRR/posts/896161700417243

and the link to the product

As I have said it before, I am big on seeing legitimate data. The OP needs to provide all of what data tables are available. Ignition being the first table I would like to see.
If there are any SoCal based members who want to see for themselves in person I'd be happy to show them beginning to end what's involved, what maps can be changed, and even install a tune just for test driving purposes. Dyno is also available for those who want to see what their car actually puts down to the ground.

You ask and you shall receive, here is an ignition table. I'm not going to post much more than this as eventually most tuners will have access and it would be easy to copy my work. All Fxx BMW's are tuneable and the tunes are available for purchase. I've spent hundreds of hours with the factory definition files (that are in automotive german) and developed the tunes from scratch.

There is no true OBD2 solution yet, it is a bench flash, it is reversible so in the event someone wants to trade in a lease or sell the car or whatever it can be turned back to stock in 30min or less.

The white car depicted actually belongs to someone at the dealership and so far there's no indication that the dealership can detect the tune.

I totally understand skepticism so I urge anyone who wants to see for themselves to come down and check it out

Wow looks promising. I wonder how much a 328i could push with full bolt-ons and your tune.

Are you able to remove the max speed limiter?

Top speed removal and
Catless downpipe tune are no problem at all.

I'm curious what they can put out with all bolt ons too, anyone with requisite mods hit me up so we can science together

Also I'd be interested in testing all the available piggybacks / tunes on the market at a third party like EAS. Also for science.

Our F20/F30 tunes are undetectable

Also we have stage 2 results now:

ok question related to that, BMS says it need dp & 93 octane to run map 2 which is 21 psi, how come it's avg. 22 psi on 91 isn't that dangerous ?!

ah now that's illustrative, cuz at their youtube page they have a video showing how to remove the ECU to be flashed and you can see the JB4 connectors ewg, canbus wires etc.

do you know what map was used when they dyno'd with JB4 without flash ?!

I live in Brasil and xenon's are standard on the 3 series, you can only get halogen's on the 1 series base model

So the Intake + DP + piggyback might possibly be JB4 map 1 + dp? Interesting.

piggyback was unplugged for the tune run, we did testing back to back with the piggyback plugged in and then removed it, we didn't bother taking the canbus wires off in case they wanted to use it for logging.

Tune, intake, downpipe. Would be interesting to see what happens with an intercooler and turbo upgrade.

As rustyminded asked what map was used on the piggyback?
