Always thought the same. Just it seems it easier for BMW these days.

I see this is turning into a Dinan discussion haha.

If warranty is your #1 priority than Dinan is your only option.

Show me some dynojet dynos that show the power gains they advertise. I've yet to see one. All the #'s from them are at the crank also.

Also B58 has some fueling limitations not seen before. Something with the DME and fuel volume. So some of your expectation might not be met until they crack it. Check n54tech for details.

I should just create a warranty company for jb4, catastrophic failure rate on any piggy back is so low you could prob. sell it for $500. I doubt it is any higher than stock.

I never take anything off. If its small, dealer will usually fix it, they get paid as well. If it is larger then it gets bumped up to the regional guy to approve anyway. If you modded oh well that's the way it goes. Only warranty I care about on the 2r is the climate control, electrical, and interior. I just leave a note on dash, jb4 set to map 0, and DO NOT FU**ING WASH!

Who is running posi tap? the firmware is like 2 years old. A piggyback could never brick a dme, it just modifies i/o signal at the sensor/controller , hence piggyback. But good luck winning that argument.

It can brick it if you ground it out with the battery connected or against the power strip up front. BMS knows about it and warns against it as well. They even have a how-to if you want to repair the DME yourself.

yeah, more likely dealer bricked it during an update

I believe the OP indicated that he removed it before bringing the car to the dealer for an issue

Not to continue threadjacking with respect to Dinan, but does it really matter if the Dinan tune is installed at an "authorized" Dinan dealer? The closest one to me is a good hour away and since it's a dealer, they wanted to charge me obscene labor costs up front irrespective of the actual amount of time it took to install the product, and at a rate that far exceeds what other work would have cost.

I'd call Dinan just to double check. In mind it order of "safety" if you want to call it that is DIY, authorized non BMW Dinan shop, BMW Dinan shop. Worst case scenario if you have a warranty issue it's either BMW or Dinan who will cover it, so if BMW and Dinan are doing the install someone who actually worked on your car is involved either way.

[QUOTE=Amack;21246711]Interesting, you think they are maybe more easy going in aus?

Maybe or maybe not, yes warranty is warranty but in certain countries are not as anal like BMWNA.

I've spoken with Dinan over this point and they have said point blank that it does not have to be installed by one of their dealers

It only needs to be installed properly/according to their guidance

Very helpful. Thank you.

I've got the old style JB4 w/ posi-tap connectors. Should I be concerned at all? Or encouraged ?... So confused, now lol.. There's a reason I left it stock and have had the piggy back waiting for FBO parts to accumulate. Now that I'm ready from a hardware perspective I'm concerned about this "Flagging" scenario which could void potential drivetrain warranty..

Unknown. Sorry. Was just sharing one persons experience and it reminded me of the m4 board post that I referenced.

Dinan is crank not whp.

I was dinan stage 3 - made less than 375, than i added a dp, i was around 390.
I ripped the Dinan off, and went flash tune, with dp and im over 400 with 40lbs tq more than Dinan.

Theres a whole thread of guys with m235s on stage 4, big turbos etc.. not even hitting 390 whp.

I have all the dyno sheets and video to prove it. But by all means, believe the sales pitch.

Bmw flags you with Dinan, but if theres an issue, they route it to Dinan to have them cover it. It's not that its allowed, or is covered under warranty.

[Shayan55]

interesting... I didnt know that the Stock DME could record and save logs like that

You should upgrade to obd, that firmware is so old and tUne I is much better on Obd. Jb4 is nice in that they constantly update the firmware, not so nice in that it's all located in a 600 page thread. I think they are rev 9, meaning your 9 revisions behind on posi tap. Tune needs the band width on the obd.

A smart refrigerator has more cpu power than most home computers 4 years ago, data logging is not an issue.

People think Dinan is affiliated w bmw, years back yes, they don't even get developmental cars, they have to buy them off the floor like everyone else. Company lost a lot of cred when Steve left. Just a 3rd party warranty really. I can see the attraction, plus when sold at dealer makes it easy for most. Resale is not so good either, the warranty does not transfer.

Of course it is, just not BMW's warranty. Dinan picks it up. That's the whole point, right? I lurk more than post, but this has been an ongoing debate I'm interested in. Seems like there's third party warranty coverage from Dinan if BMW won't cover it.

Asking, not telling.

The whole point is its not BMW, its Dinan. And have you ever tried to reach the claims department?

A friend of ours had stage 3 and had an issue, his car sat at bmw for 3 months while he paid for the rental car.

3rd party warranty... exactly what it is. The amount you pay for Dinan, and what you get out from it... your better off going a different route and just keeping some money aside for the What If Scenario.

A JB4/flash tuned car with DP's will absolutely destroy a Dinan stage 4 car.

I do still like there hard parts, FMIC, intake, springs etc...

I would like to see some proof of this. My friends M4 with a JB4 was definitely faster than mine but was not blowing past me with a dinan stage 2 tune and intake in my m235i.

also My M235i stage 2 dinan 2 felt as fast as my 135i JB4 twin turbo.

I think the word destroy is more like a tenth or 2 tenth a second. And I know from experience that i was very lucky with my 135i blowing 2 MAFS and 2 PUMA cases opened against me that post some VAG tool code deletions i didnt get caught.

We could all totally save 2k and put it aside for when and if something goes wrong with an aftermarket tune, and when it does, my guess it will be about twice that cost.

[bryan_G01]

you have a downpipe which is probably another 12whp.

If you were to dyno it, id guess you are around 370whp.
That m4, 470whp. If he added downpipes, 500whp.

Theres no way ur car can keep up with it unless you only tried to run a block or two.
Or you are awd and hooked while he was spinning.

I wish the cars were faster, but they are not.
