Just wondering what everyones thoughts are on the DINAN stage 2 flash. I want a flash of some sort and like the DINAN because it's error free (user error free) and is covered in warranty. The other flashes don't seem to be like that... or are they? All these picking of maps and stuff scares me... don't want to ruin my engine...

With that being said, the DINAN chip is about $2300 installed at a dealership... And that's a TON of money for what other chips are doing for a couple hundred bucks...

Your thoughts? And yes I've searched and read, but I'm still just very cautious of ruining things on the E92 (Considering my E46 turned to crap cause I ruined so many things "modding" it)...

Dinan is a rip off. The only thing you're paying extra for is the warranty match, which is moot if you're careful anyways. Plus, your car is an 07, so the warranty is no longer a big deal.

Whether you buy the JB3 or the Procede, buy it - its like upgrading to a big V8 without the gas mileage drop!

[enrita]

if you want a flash get GIAC instead of DINAN. 900 bucks of pleasure and trouble free power.

+1 Dinan is way overpriced. If you have settled on a flash over a piggy like the JB3 then enrita is giving good advice. All the data I have seen from GIAC is good

Yeah, on an 07 like me you would be paying for a year warranty tops, plus it makes it impossible to get the BMW extended warranty.

I'll agree with this.

However, in respect to piggy backs like Jb3, picking maps isnt that hard OP.

Stick with map 3 if you have concerns, its conservative yet offers more power then the DINAN.

Worst case scenario you uninstall it for warranty work.

If you are really concerned since you are saving so much money going a Jb3 route, you can get yourself a BT Scan tool as a just incase. However, im 99% confident if installed correctly (the jb3), that you will never need it using Map 3.

If you're set on a flash tune go with GIAC.

If you want my opinion, I say go with the JB3 2.0.



GL with whatever you go with. The N54s are a lot of fun with tunes.

yes they are

I raced a Dinan State 3 coupe the other day

Guess who won? :P


even with my 400 lb disadvantage :P

(RR CP, Helix FMIC, JB3 1.4beta map 5, BMS DCI, scoops. the CP and the Helix does through it off... but there is that 400 lbs...

[Dr_Dirt]

Does the GIAC have the same throttle response as the Dinan stage 2?

[mycoupe]

Well, according to what my service rep told me a week or so ago...Dinan and BMW have split and Dinan upgrades are no longer acceptable according to BMW. Anyone else hear about this?

Well as soon as you flash your car with Dinan, your BMW warranty is void. A Dinan warranty takes the place of your BMW 4/50k warranty.

Only certain parts of your BMW warranty stand, and Dinan offers some of the things you lose as their form of warranty.

There is a lot of fine print from what I'm told.

People make it out like you keep your factory BMW warranty with Dinan products which is NOT true. You keep some stuff.

If you or someone else is interested in specifics they should contact Dinan and/or the dealer.

Neither statement is totally true, to my knowledge.

1. Dinan and BMW have NOT split**;

2. While Dinan parts are covered by a Dinan warranty, your Dinan-ized car is still covered by the BMW warranty. When I take my Stage 2 car in for service, I remind the SA that it has Dinan software and not to re-flash the ECU w/o checking with me first. The warranty work then continues normally (last visit was low-pressure fuel pump replace).

**There is another thread that discussed a BMW memo about Dinan cars no longer being elligible for the Certified Pre-Owned program. In that case it seems to me all you'd have to do would be to flash your Dinan ECU back to stock.

As to the OP it seems probable that the votes so far reflect the poster's biases based on their own purchase decisions. Understandable.

So while I have no experience with either of the other flashes or 'piggies' my own vote is for the Dinan Stage 2 flash: smooth, tractable, and very powerful. All I could ask for.

And, as always, YMMV. Just enjoy whichever mod you decide upon.

I don't think its that simple, im pretty sure that your VIN is flagged once you've had your car flashed by Dinan and thats how BMW knows to work with Dinan for certain warranty claims.

[1qkviper]

Does anyone have any data on the difference between Dinan S2 and GIAC S1?

[erm324]

I had Dinan stage II and exhaust for over a year and a half...was very happy with it until i crossed paths with a jb3 (only) 335...I got raped by at least 5 cars and switched to jb3 and never been happier....

[Donald-335i]

Dinan Sucks to much money sucks performance wise it all sucks

buy a jb3/procede....

[alpinedevil335]

Map switching is not rocket science.
With the JB3 just install it and forget about it. No need to switch from the default map3. (if your gonna stay conservative) Like others have said, Dinan is overpriced. You will get more gains from a piggy or a flash other than Dinan. If your set on a Flash you cant go wrong with GIAC.

[OpenFlash]

There is really no reason to ever choose Dinan over other tunes these days.

If you were buying a newer 335i and your dealer has a good relationship with Dinan, Dinan is definitely worthy of consideration, despite what the purveyors of the other toons and their nuthuggers will tell you.

But for a 2007, I would agree with enrita. You don't have a lot of warranty left so the GIAC flash would be a great call . If you went the Dinan route, you'd basically be paying a premium for a year or less of coverage and that's kinda hard to justify.

[M4TW]

I've been running a Dinan flash for over two years with no issues, no hassles with my dealer, no need to erase engine malfunction codes, no need to commit fraud, and with smooth responsive great performance.

The Dinan tune does much more than just jack up boost. Full access to the ECU has given engineers at Dinan the ability to improve many other engine control functions without having to override or trick the engine's safety parameters. For example, it drives the water propeller faster to create better cooling in the engine, since increasing boost adds to the heat problems from which these cars already suffer.

But it does come down to warranty. Since Dinan are prepared to guarantee that their products won't damage your engine, they take a more conservative and responsible approach to engine tuning. Remove that, and what the heck, might as well crank up boost to the max to the delight of the kiddies who mostly turn in their rentals after three years of abuse. Then it becomes someone else’s problem.

If you are outside the warranty period, I’d also give a company like GIAC a look since they have embarked upon the exercise in a comprehensive way, have a place of business other than their garage, and actually have engineers on their payroll. Dinan have a more extensive dealer network though and you’ll find them right in BMW dealerships.
