Can you confirm you have MPPSK?

I do not, and should have paid close attention to the title of this thread.

No problem, easy mistake, thanks!

I still thank you for linking to your dyno - stock dynos of 340iX are rarer than 340i.

[scofflaw]

Well I went ahead and ordered it, should be here next week. I'll try to get a dyno after installation if I can locate one in my area.

If you can do a before install dyno run and an after install run, due to variations in dyno's it's the only way to get really meaningfull numbers. The delta between the before and after is what's really important, not just an after number which without the before won't really tell us much.

Unfortunately due to the timelines I'm not going to be able to do a before run unless I seriously delay putting the S1 in. I work over 60 hours a week and the weekends are my only time to squeeze a few things in; once it gets here I'm going to throw it in.

Understood, I wasn't able to do before and after my MPPSK for pretty much the same reason's. Let us know what you're thinking after the install.

Can’t you just run the Dinan in pass through mode or where it’s not turned on then turn it on and run again? And congrats Scoflaw you waste no time, car will be a rocket!

People are convinced that the ECU 'adapts' and you won't get accurate numbers switching back and forth that way, because it hasn't had time to 'adapt' to the different tune.

Experienced tuners in the space should know how to reset the ECU to clear any long term trims or if it resets every time you turn the engine off, and what PIDs to monitor to find out if it's still adjusting trims. With many cars, hopping on the highway, going up an exit, turning around and coming back would likely clear it out, if it won't clear up in a couple dyno pulls.

I will mention this when the time comes, thanks.

How much longer until it comes and you get it installed? You’re just going to run 91 right? I’m so anxious to see dyno results!

It will probably be next week or so for install. And yeah, unfortunately only 91 (+E85 occasionally) for now. I might make a trip to the Bay to find some 93.

I messaged Dinan and asked if the tuner adjusts to 91 they said it does. Waiting for their response on running e85. They said on 91 it should run smooth like stock MPPSK during normal driving and hard acceleration, not sure what the bad reviewers are doing wrong.

[scofflaw]

I've got an appointment next week for S1 install so I hope to have something positive to report after that.

[scofflaw]

Well I had the S1 installed this morning and have driven it maybe 70 miles since then just messing around tonight.

I honestly can't say I notice an appreciable difference (yet?). I feel a little bit more torque in the lower range of Comfort mode, but Sport mode feels about the same.

I haven't been able to push it hard yet but it doesn't seem noticeable. I've made sure it's enabled on the app.

Sport+ feels like a rocket as usual so I can't comment if there was any change there.

Hoping to get a dyno run soon.

I really wish I could say I was confident enough to order this for my 440i Xdrive with 6MT & MPPSK. In Alberta some gas stations have 94, but most have only 91 (which is what I usually get). it would appear the odds are against me based on what people have said, due to my combination of 6MT, Xdrive, & more regular usage of 91.

gonna play it safe for now.

[riskmaker76]

If you already have the MPPSK then I would most definitely sway you away from any piggy backs while running 91 octane... IME even with 93 octane here in NY some times my timing runs pretty low in the summer with a JB4 on Map 1. To the point I have to go to Map 6 and put in 2PSI (custom map) to maintain timing.

That is an option for you - a JB4 and then you can just define 2PSI if 3PSI (Map 1) is too much... the true benefit of the JB4 is knowing how your car is responding to the added boost..

however, each PSI is about 10HP - may not be worth the cost in the end - and you might find, its worse performance with any added boost because of timing being pulled so much..

thanks for all the info man!! the main reason i was looking at the Elite was because I could keep my factory warranty.

JB4 is something that I might consider in the future, after my warranty is up.

Ive had it for a year now and while it works fine in the winter the summer months bring check engine lights and stuttering when idling and accelorating.

I'm reaching out for a refund at this point because the car has been at the dealer so many times for this issue and its just ridiculous at this point.

Regardless of the fact that NY may have "bad" 93 it shouldn't be so bad to the point that the product doesn't work as designed.

[riskmaker76]

I know others who have the same setup - they have no issues up to map 2.

I really think its the fuel quality in NY - almost believe these stations are not giving us 93 octane.

The cars performance and driveability varies too much from station to station.

PS - go to map 6 and define it to 2psi. Its major improvement in the summer months..

If you have the EWG wires you can fix the PSI to 15 or 16.

The issue lays when timing drops - computer seems to recalculate and for that session becomes a mess... if you can keep timing consistent all issues go away. Need to log and find the right balance

Is the fuel in NY high in ethanol? From talking to friends who know far more about tuning than me, making up octane with ethanol has downsides, because the energy density of the fuel decreases. So if your 93 is '91 mixed w/ 15% ethanol' it will technically meet the definition of 93 (it will have the same detonation resistance as 'pure gas' 93), but it will behave differently than 93 w/ 0% ethanol.
