Looking forward to peoples dyno results when they get this installed. But I doubt it'll be any more power then the MPPK offers... If I'm wrong and their figures are to the wheels, then I'm in. But I'll sit back and wait for real world results.

Measuring apples to apples (flywheel hp to flywheel hp), Dinan's stated gains are greater than that of the MPPK. Eventually, someone on this forum will get one and do a before/after roller-dyno comparison on their car and we can see how true the claims are. Even then, figures vary from dyno to dyno, so personal experience is probably the best way to judge.

In the past, Dinan has quoted HP figures at the axle, not the crank. I had a link to one of their pages that explained this methodology in detail in this post from last Fall; the link is no longer active, but as far as I know, this is still their process.

I didn't experience any traction or stiffness issues - although I didn't track the car. I would have added their chassis parts if I was going to spend a lot of time on the track. For the street, I bumped the tire sizes 1 notch to 265 rear and 235 front (non-runflats) and that worked well.

Since I've primarily driven the 3 series as a bridge between M3s (or 4 series between an M3 and an M4 in the current case), I only do a mod if it is very cost effective. I too switch to non-run flats when the run flats are done. Anyway, my 335i (with sport suspension) was very entertaining and would do massive power squats in the lower gears with the extra torque from the Dinan tune.

Well no one is going to know for sure how much power difference there is and that is what bothers me. We all 100% that Dinan did dynos using their method on a completely stock car. Why is so hard to get those numbers. A before and after of a stock car on THEIR dyno with their methods. Then we can compare the delta to before and afters or the JB4 or MPPK as others have done numerous times already before.

I'm going to be doing a comparison dyno day with a stock 335i, old MPPK, new MPPK, and JB4 in the next week or two. All pulls will be done on the same day, same dyno, back to back. All cars are RWD with 8 speed auto.

Wish we had a Dinan tune in the mix for this but not many people are willing to fork out 2k for this tune especially since they also have pay to have to install as per the Dinan website and a measly 3 day return policy.

Can't wait to see these results.

Please do.

Still wondering about getting either the JB4 or the MPPK.

I really wish someone around the NJ/NY area had a Dinan tune to add to this dyno comparison...

First impression: I thought I wasted my money when I first drove off the lot with this thing on. Doubted any changes in numbers, throttle response or any enhance performance period. Well it's been a week since I've had the dinan tune and yes fellow tuners it's butt dyno approve. I guess it took a little bit of learning curve on the computer for the tune to kick it but power delivery in all ranges is instant and you can definitely feel it pull in the high speeds. Always sucking me into my seat which I love. Feels like I have a new car again . Only downside which I'm not sure if it's the tune or how 335 are but first gear(sport auto) is jerky in sport+ as in not as smooth on acceleration as I would like it to be. Other than that no complaints. I will post dyno numbers as soon as I get a chance and hopefully I can get a baseline w/o the tune but the shop(HG Motorsport) has to call dinan to check how to retrieve oem map. Paid just a little more than what I would have for MPPK and with the significant difference in numbers it's an obvious no brainer. Noted that to each their own and everyone will have their opinion but I have also used jb4 when I had the 328 and liked it but not in love with it. The performance and not to forget the most important part maintaining the warranty was money well spent in my book.

[tsims619]

Oh yea heads up expect your tech to have complications installing this product as did the bmw dealer that did mine. I guess this is where the sophisticated factor comes to play. Also every tune is programmed with your vin as to why I'm not sure but that's the info that was shared to me by my parts guy.

[Rxpert]

Congrats on the new tune! And thanks for being the first to take the plunge. I'm eagerly awaiting the dyno results......

Btw, if you are close to the other guys you it would be amazing if you could get together with them to dyno the Dinan vs the MPPKs

Sorry bruh I believe they're in NY and I'm in SoCal. Otherwise it would've been great to do a comparison with the 4

[energyIB]

tsim619 do you have any other mods besides the dinan tune on the car?

Looking forward to your dyno numbers. Sounds promising. Please keep us posted.

I don't know much about Tunes but why would there be a delay in feeling a difference? Shouldn't it work right away, like any other mod you do to the car? That doesn't make sense to me.

Same is reported for the MPPK. A lot of people seem to think the ECU needs time to "learn." This is completely false. There is no adaptation as all the parameters will remain identical. The car will perform the same on the day of the install as it will a month later. If they dyno the difference right away versus after time spent to "adapt," they'll notice the results will be identical.

If a difference is not immediately felt upon applying throttle for the first time, then the gains are not significant. After time, the gains might be more apparent simply because the driver has driven the car on roads they are most familiar with and has put the car through all different levels of acceleration.

No other mod in the vehicle except for wheels/tire and suspension that carried over from my 328.

Not accurate - even BMW tells you that the ECU will fully adapt to the MPPK upgrade after 200 miles or so. That was the case with mine, and I got mine right after they became available. I took a 450-mile round-trip drive right after installation and the difference was noticeable at the halfway point. The F30 ECU, just like that of the E9x series, adapts to your driving style. There are numerous published posts about how to re-set your throttle adaptation, etc. Yes, the parameters are the same, but the ECU still needs to adapt. When installing Dinan S2 and S3 in my N54-engined E92, it always took a couple hundred miles for it to fully adapt.

[HX_Guy]

Hmm, so realistically then you can't do a back to back dyno before and after install? That's a bummer.

Not same day, but yeah, you can. As long as you drive a couple hundred miles in a week. I cant imagine the weather would be different enough in a week to have an affect on the outcome of the dyno.

[HX_Guy]

Dinan released dyno charts of the Stage 1 in the M235i...gains aren't nearly as good as originally stated. The peak numbers are the same, but the stock baseline numbers are much much higher. Their specs originally said +44 HP and +79 TQ, but they were basing that on BMW's quoted numbers of 320HP/330TQ.

I was always curious as to why the M235i was quoted as 320 bhp while the MPPK-equipped 2014 435i was 335 bhp. Why would the M235i be that much lower?

[BEAR-AvHistory]

Most like BMW tunes them like that to keep a spread for marketing reasons.
