Does anyone know if HP/TQ increases show up on the sport display screen with the Dinan S1 installed? e.g. if I hit 380TQ now, after Dinan will it hit the max of 400TQ in the sport display?

The display will not adjust upward if my memory is correct.

It does not, I have the Dinan Elite Stg 1 and it doesn't make a difference vs. Stock unfortunately.

Do we know if the power and numbers provided is at wheel or crank? trying to compare it yo the JB4 with 340 MPPSK.

All Dinan products are advertised as crank HP.

Just wanted to check in with people who have 340/440 with both the MPPSK & Dinan S1 - Are things still going well? car driving smooth in comfort? Still pull with a nice noticeable power boost with the Dinan S1? no CELs in past 6 months?

I have the MPPSK and have been on the fence for the S1 and I can't find much updates from 2018.

Also, I spoke to Dinan the other day, they had a firmware update about 2-3 months after initial release but no new updates since; so what's out there is the latest offering. I am considering waiting until the S2 intake drops as I assume a firmware update would come which might have minor enhancements.

No prob. I hate to hear bad things about Dinan. But if there is a solid group of people having issues, it should be known.

[Xanderdbs]

im really hoping they fix all these buggs and issues when the stage 2 comes out. Imagine paying $1400.00 to have the car at the dealer frequently. Everyone could just go with other aftermaket tuners and take it off worst case if it causes an issue.

Dinan is fouling up but i really want it cuz of how smooth the power delivery is

I have MPPSK 340i M Perf. Edition with Dinan S1. No problems here! I did have an issue at the start, but it was a BMW spark plug/injector issue, all was replaced under warranty.

I'm still loving it!

I have a 440i with MPPSK and Dinan Stage 1 (D440-1655-ST1), and have had no problems. Both tunes were dealer installed. The MPPSK upon delivery in June, and the Dinan tune in August after 1,800 miles. I currently have 4,500 miles, and track it once a month since August. The car is as smooth as stock, and fast as Hell, and yes, the Dinan made an already very fast car noticeably faster. I regularly hit 130+ on the track, and do the commuter shuffle around town so I am pretty much using the engines entire repertoire. I couldn't be happier with it.
I had the car dynoed with the MPPSK only, and again after adding the Dinan tune and these are the results:

MPPSK: WHP 338 WTQ 393
DINAN Added: WHP 369 WTQ 410

Dinan uses a crankshaft to wheels HP loss of 12% and a TQ loss of 8% so since they know a lot more about these things than I do I have used these numbers to come up with crankshaft figures of:

MPPSK: CHP 384 CTQ 427
DINAN added: CHP 419 CTQ 446

Not exactly Dinan's advertised CHP of 426 and CTQ of 463, but damn close, and a whole lot of fun for the bucks. One thing though, you folks who are waiting for the Stage 2 tune are out of luck. At least for now. Dinan has stopped selling their Stage 1 tunes for both the stock B58 (D440-1650-ST1), and the MPPSK (D440-1655-ST1). In their place they now offer a new tune called the Elite V2 (D440-0122) which applys only to the stock B58 not the MPPSK, and produces less power. Peak CHP 396 and peak CTQ 379. I would love to know what's up with that.

what fuel do you run...

You can find info about the Dinan Elite V2 on this thread

Apologies, I don't how how to link directly . . .

[Boomer 2019]

I use 93oct Shell V Power. Don't know why really-just silly human brand loyalty. Any good 93oct fuel should work just fine, and being in Miami, the gas companies don't do a lot of tinkering with their additives between summer and winter. I have read of people who seem to have issues with 91oct but I can't speak to that. Hell, you can't even find the stuff down here, and who would want it anyhow if 93oct is available.

If anyone is interested I have pictures of my dyno run graphs which I would be happy to post if someone can tell me how to do it. I am new to this.

2019 BMW 440i Coupe M Sport 8A 1st Image MPPSK / 2nd Image MPPSK & Dinan Stage 1 Tune (D440-1655-ST1)

Runs were done on a Dynojet wheel dyno with temps in the mid 80's and humidity in the mid 70's.

I have also found out that the new Dinan Elite V2 Tune is added to both the stock B58's and those with the MPPSK installed.

Has this thread morphed into an inclusive Dinan Elite thread? The non-MPPSK thread hasn't been active since 2017.

Reason I ask is that I had my 2018 440i GC give me Drivetrain Malfunction and Chassis Stabilization errors last Saturday. Called BMW and told me to have it towed to dealership. When BMW plugged in to download the error codes they said it had 47 different errors associated with event. Nothing broken thankfully. They subsequently disconnected Dinan Elite and asked me to drive for a few days to prove if it was associated with the Elite or not.

Based on what I've read here sounds like the Dinan could be the culprit. I'm hopeful they'll either get me a new unit or upgrade to v2. Love the HP boost.

Thoughts?

[bimmer456]

So you need 93 octane for this tune to work? What kind of numbers do you get with 91?

Dinan has produced 3 separate tunes for the 340i / 440i starting in 2017. They are all called Dinan Elite. Dinan Elite Performance Stage 1 (D440-1650-ST1) is for the stock B58 engine. Dinan Elite Performance Stage 1 (D440-1655-ST1) is for those cars already equipped with the MPPSK tune from BMW. Both of these tunes were discontinued by Dinan a couple of months ago, and can now only be found available from several after market companies. Google it. The third Elite tune from Dinan for the 340i / 440i is brand new, and is called the Elite V2 (D440-0122). It replaces the previous two, and can be installed on cars with or without the BMW MPPSK tune. It produces less HP, and far less torque than the previous tunes, probably due to the problems that so many people were having. Most of us who have the previous tunes have had no problems, and love them. My personal suspicion is that the problems occur on cars using lower octane fuel, or adding octane boosters like ethenal, and perhaps some add on parts that alter the fuel air ratio. I am not making claims here, just my thoughts, so don't jump down my throat. Obviously no one knows for sure.
So which of the "Elite" tunes is your car equipped with?

No head biting here. 👍 thanks for taking the time to respond.

I have the D440-1650-ST1 (stock b58). No mods other than that. The only thing I changed recently was going to Shell and using their 93 octane for the last 4 tanks. Previously was using 93 from whatever gas station was convenient...never ever put anything lower than 93. I'm in NC if that helps.

Before the latest issue, I had 2 other "weird" things happen. 1st Time was turning corner, in comfort mode, and car just took off on me. Felt like I was in sport mode and hitting the gas pedal hard. Happened for just a few seconds, but was totally caught off guard. 2nd time was driving 35mph and felt (what I think was) engine shift down/up really quick. Only way I can explain it was thunking/hiccup feeling. Felt like I ran over something in road with both rear tires, but there was nothing there. Both people in car looked at me like wtf was that?! Both weird instances didn't cause any errors.

2 days later the car gave me the errors from the initial post. Was running perfectly up until that 1st issue.

I really miss the extra power and hopeful the problem will be resolved this coming week. Is there a particular v1 hw revision that has better track record? Should I ask for a v2?

Very weird indeed. I hope you get it sorted out, and back to trouble free motoring. I would suggest however that you give it more than just a few days with the Dinan disconnected before bringing it back to the dealer. You know how quirky and random car problems can be. If you have no further problems and all checks out good when you bring it back, see if you can talk them into reconnecting the Dinan as a double check. If it is the unit, the weirdness should return shortly and then everyone involved will know for sure that the fault lies in the Dinan unit. This might help you when you raise the warranty issue with Dinan.
If you do decide that you want to give a Dinan tune another chance then your only option will be the new Elite V2 (D440-0122). They will no longer provide you with a replacement Stage 1 (D440-1650-ST1). The V2 has not been available for long enough to provide any customer experience or feedback, so if you go this way you are going to be a pioneer. Again, best of luck to you and let us know what happens.
