Thank you for the feedback. I have a 428I as well. The only thing keeping me back is warranty and long term reliability. I intend to keep this car for a while. If only GSR offered its own warranty like Dinan I would do this today.

Hey Guys ( GSR ) been reading alot of great things about your tunes and also stuff on the JB4... Not looking for comparisons or start a war between which is better.
But wanted to see if you guys offer or in the future will be offering something similar to what Cobb & APR do for programming via smart phone or handheld device?
With something like that you connect and in 5 mins your tuned... 5 Mins later you can be un-tuned and back to stock.

I love the fact of running a direct tune and not a piggy back but the convenience of the piggy back is currently a plus if I have to goto the dealer for anything.

While researching N20 tuning options I am getting poked fun at from my colleague who owns an STI that in 2015 I have to either run a piggy back or send my ECU out to get re-tuned...
Is this something maybe coming down the road?

All in all looking fwd to more power so a tune is in my future, Keep up the great work...

Wow that is a great feature! I didnt realize APR offered that. I need to look into that and see how it works so I can get my nerd on! May need to go back to owning an Audi just for this feature!

BTW just checked out your build post, Awesome car!!! I have an alpine white F30 328 sport that I just started modding and want to code my lights...

Thanks man! I really appreciate it. Modding is a fun hobby. I am always thinking of more and more things to do.

Coding lights is easy once you get the cable and software. PM shawnsheridan and he will set you up.

Looking forward to seeing your mods!

Thanks man, I will message those guys soon I just ordered the cable. As for the tuning I was speaking on earlier.. It looks like someone has a way to read and modify the ECUs - https://www.youtube.com/watch?v=wEAtzSKINws

If someone like GSR ( would be awesome ) can package this up we will be on our way to flashing and reflashing on the go from home where they sell the device or app + the tune but just with added convenience.

Spot on. Really want to have ecu fleshed but that takes intercontinentally shipping it. Anything wrong from the moment I send it out I am screwed.

Updated in my original post dyno results with the GSR stage 1 tune on. Sorry guys, wasn't able to do a baseline dyno to show the delta, but thought I'd share this anyway in case you're interested.

Thanks to kevin @ eas for the dyno - truly a great shop.

Also did some acceleration runs and timed them with the m-laptimer app and shared those results too. I know they may not be super accurate, but it was fun to do and thought I'd share them too!

[chuckles01]

Thanks for posting those ROBNYC, great to see them all in one thread to compare!

Yeah, I'm on 91 octane as well and without any other mods... just the GSR stage 1. I could be mistaken, but from what I recall following all the GSR tuning threads from way back, the stage 1 originally produced higher numbers, but was changed to be more mild so people wouldn't run into the auto transmission limit. Some of those dynos may be with the previous tune or may not, I'm not so sure.

Matt mentioned that 260 whp is probably the safe limit on 91, though he offered to give me more power if I wanted. Getting 270+ would've been nice, but I think to be safe and not over stress the car, I'm happy with the numbers now, especially since everything else is stock.

While I personally can't compare the difference between the two since I've never driven an F30 with a piggyback, from what I can tell so far with my own car, the GSR tune is extremely smooth. It really just feels like the car came this way from the factory.

I also haven't had the chance to drive a 335i. Now I'm curious to see how a tuned n20 feels vs. a 335i.

Well I can tell you from test driving a stock 335i M ( hammering it both directions ) on the freeway,and driving stock 328i M the 335 had a big edge.
Fast-forward 3 months after buying the 328i M I chose it because it was Estorial Blue and the 335 was black /red interior not my taste .... I did the dinan stage 1 and now I can honestly say they are evenly matched maybe the 328 has a small edge because it is a few pounds lighter .Also I have installed a shadow 4 throttle re-mapper so I am 9X faster on acceleration than a stock vehicle. the shadow 4 is a must have.

It may feel to you its evenly matched or small edge but you're wrong in both.
Dinan stage1 is so conservative on the N20 its slower than a BMS stage1 or Racechip (stock setting) comparable tunes.

Matter of fact Crashnbrn5 mge92 and I can tell you we have compared

X3 35i (N55) stock
X3 28i (N20) stock and w/ RaceChip and w/ DP + EnzoTuned Flash
X3 28i (N20) Dinan Stage 1 MWG (removed Dinan and then) w/ DP + EnzoTuned Mild Flash

We recorded videos of X3 28i Dinan Stage1 vs X3 28i RaceChip (stock settings, and about 3-4 diff settings) and RCU car beating the heck out of Dinan. Not only that, but for the amount of money it cost, its not worth it not even for 10yr/100k warranty lol #Sorry

I'll post a video later

I can only say what I know . I drove both cars and I own one of them .I don't know about the flash tune and the race chip .after researching many different tunes out there I picked dinan . If it ( car )didn't have a warranty it may be something different. Even Dinan said there are other tuner kits that have more HP and TQ but the parameters are not finely tuned for this kind of ECU. Whether its true or not I don't know , it just personal preference at this time. I am always open for correction and new ideas, and I am never ungrateful for good advice....even at my age,: drink: Cheers.

Dinan = Marketing Experts

But if you're enjoying it thats all thats important
You guys over in NorCal or SoCal should setup an N20 Dragday

If we had Dragway weather like you guys here in the NorthEast we would be there in every week lol.

[chuckles01]

Yeah, I still have never driven a 335i or a Dinan-tuned 328i, nor have I raced with anyone else so I can't say anything with certainty how I stack up against the various different tunes.

However, I do know that my GSR stage 1 tune is a mild one, since I got the revised version that doesn't put as much stress on the car. I'm sure that there are piggybacks out there running different maps that produce way more power than mine. I was under the impression that my gains, though mild, should put me close to a stock 335i territory, but I don't know.

What I did do for fun is to time myself via the M-laptimer app doing various runs and comparing them to test results from car magazines. Not scientific at all I know, but was just curious. As you can see from my first post, while my 0-60 isn't great (chalk that up to poor manual launch skills, and a reluctance to abuse my clutch ), nearly every other stat is close to a stock manual 435i tested by C&D.

chuckles01 i dont know if i asked before but was your Dyno on 91 or 93 octane?

Regardless is still nice 262whp/293wtq but without seeing you base (stock) run you would not know how much you really gained also it may be that Dyno reads high (sometimes they do).

Although not very comparable since I had a X3 28i (N20) 4200lbs car my buddy mge92 and I took our cars to dyno.

13' MWG X3 28i Quad Exhaust on BMW Heavy 20's Dinan Stage1
243/257 1st run
250/262 2nd run
255/273 3rd run

14' EWG X3 28i w/ RaceChip on bmw 19s
224/254 stock run 17psi
251/285 2nd run 19psi (RC on)
259/292 3rd run 20.5-21.3psi
266/298 4th run 21.9psi
274/303 5th run 22psi

Hopefully with all the GSR and other tuned cars in Cali you guys can go do some runs at the dragstrip =D or setup a DynoDay with MissionPerformance
Bmw doubles already on his new tune

I hear ya After talking the tech at the Dinan shop he told me the stage one and the new upgraded software he put in the car its safe to say I could see dyno pulls at around 310-325+ on the HP and 300-335 on TQ. He has seen these numbers for himself at the shop using the hub type dynameters, the roller type are inaccurate due to poor contact and tire slippage He claims to have seen stock~328i, numbers as high as 265hp. I plan on dyno `ing my car this summer, I will post the results. Fingers crossed its 300.

[chuckles01]

I'm on 91, but yeah, I never got the chance to do a base run so it's hard to know my gains. The shop that dyno-ed my car did show me a stock dyno of a different f30 n20/26 they did on a different day, and the numbers were around 223 whp / 245 wtq or so. They used a dynojet. But, I know you can't really compare dynos on different cars and different days.

Your runs must've been on a mustang dyno since it's awd? Those dynos read low, so comparably speaking your n20 is probably putting out way more power than mine.

You talking whp or crank hp? I read somewhere that with the dinan tune you can set it to bypass mode (reverts to stock), so maybe you can easily do a stock dyno and a post-dinan dyno and see your gains? Looking forward to seeing your results!

These are AWD Dynojet and bigger drivetrain loss on X3 cars (4200lbs)
So being that your car might be RWD will do better on a Dyno i think.
224/254 for my stock run , SAE and Smoothing 5 i would say is pretty accurate Dynojet

At the time Dinan didn't have the bluetooth for bypass and not sure any other way mge92 could prob chime in

[chuckles01]

I see that you got rid of your X3 though - time to tune your X4!

Dinan didn't release the bluetooth bypass until this year. We already had dynoed the car beginning of last year and even a couple times in 2014. Dinan is a great piece of hardware if you want a simple ability to switch from stock to tune however it is just too conservative. Although, if you want a tune that can take advantage of other mods such as catless downpipe where you have the ability to keep the engine light from popping up for being catless and optimizing your power go for a custom flash.

Summary : Dinan wants to keep its CARB rating on all its products thus you will not see any Dinan product pushing any boundaries.
