I have a dinan stage 2 on my car right now on my AT 335i that has the factory oil cooler equiped and the BMS DCI. I was doing some research as to what it would take to make it to stage 3. It says that I need the Dinan intercooler AND the expanded oil cooler in order to get to the next stage....If I got just the intercooler upgrade and kept the stock oilcooler upgrade would they still put the stage 3 software on the car, granted I expect it to void the warranty but im at 48500 miles as we speak so it doesn't mean too much to me. My main goal is to get some downpipes and an intercooler at the same time as the stage 3 flash.....is this possible or is the Dinan oil cooler upgrade nessicary (That makes a world of difference in my choice)

[dlbrooks18]

The answer is YES. You can get Stage 3 flash right now for the difference in price which is like $400, no more upgraded parts if you don't car about voiding your Dinan warranty..and your just about out anyway, so flash away!

[MyVi335i]

awesome, I do plan on working the intercooler and a set of downpipes. I think the factory oil cooler will do just fine as of now. I just didn't know if they would put it on or not. I will be investing in an extended warranty but it wont be from my local BMW dealership because they have fucked me over more then all my ex girlfriends combined. I love my car, I just feel like the dealerships are all a bunch of theives!!!!!!!! and if anybody out there is in my local region dont go to the dealership to buy a car in Lincoln Nebraska. I have yet to come by a positive experience!!!

The Dinan dealer or Dinan rep Indy shop gets paid for their time regardless. They just will tell you that your warranty may not work. But if you have had it for a while. It will run out soon. You would probably be fine with your current oil cooler if you aren't tracking hard or anything. Another option is to get an aftermarket oil and intercooler or for a good bit cheaper than Dinans. Not like they are much diff anyways. Then you still have the so called required upgraded parts. Just not Dinans

[cstavaru]

Why would you get Dinan when your warranty ends anyway ? Get GIAC Stage 2 (also you need a $300 set of downpipes and a $300 intercooler), it has the same reliability and stability as Dinan but much more power. Of course, it's more expensive than your upgrade price but I think there is a group buy in the vendor section somewhere these days. I think that even GIAC Stage 1 has more power than Dinan Stage 3.

IIRC the Dinan Stage 3 tune doesn't take into account catless DPs so you'll be driving around w/ an SES light all the time & possibly misfiring since the engine will try to correct the AFRs in response to the emissions the o2 sensors are picking up. Like cstavaru said, if you're interested in upgrading your DPs & FMIC and you won't be tracking the car (only reason to upgrade your oil cooler), get a tune that let's you benefit from these mods & will cancel out the tuner (DP) codes from appearing on your dash.

u can get CPE intercooler and oil cooler they sell them as a kit too

[RoundelM3]

I have Dinan Stage 3 but I have 3rd-party intercooler (ETS 5") and oil cooler (ER Sport). The guy I work with at my dealer's Parts Dept. called Dinan and asked if they could flash my car without having their "required" parts, and since I had non-stock FMIC and OC, they allowed him to do the download. I am also nearly out of CPO, and that may be a factor, but I would highly recommend you upgrade your FMIC and OC before installing Dinan S3, as you won't get the full benefit without the FMIC. The OC keeps your temps down, and I'd recommend both items for any higher-level tune. Also, if you get catless DPs, you will need a "DP Fix" such as that from Burger Tuning, but Dinan's tune doesn't recognize DPs, so it won't really take advantage of them.

And you'd be wrong on that one. Dinan Stage 3 with FMIC, exhaust, and their CAI dynos at 408 hp. GIAC Stage 1 is closer to Dinan Stage 2.

No Dinan car will ever put down 400whp.

[rader1]

Here's a Dinan stage 3 dyno. 339/380 on a dynojet. I made more than that on Cobb stage 2 on a HEARTBREAKER MUSTANG dyno.

Straight from Dinan's website

With a peak horsepower of 398 at 5700 rpm and the peak torque of 429 lb-ft at 4300 rpm as tested with Dinan High Capacity Oil Cooler System and Dinan Free Flow Exhaust is a monumental increase over the stock 300 horsepower and 300 lb-ft of torque BMW quotes.

Since we all know that the stock 300/300 is flywheel power, the Dinan S3 at most is putting down 350 WHP/365 WTQ. These are basically COBB Stage 1 Aggressive numbers. I'm not saying there is anything wrong with the Dinan tune, but it is by far the most conservative tune on the market.

[RoundelM3]

Nor will any GIAC Stage 1 put down that kind of hp either. But regardless, go to Dinan's web page and read their stated ratings. I'm not interested in getting into a pissing contest about whose tune has the biggest balls, just stating facts - which a lot of times seem to be forgotten about.

You're leaving out the rating with the CAI - stated at 408. Again, I'm not interested in proving a pointless point. I could care less what Cobb, slobb, precede, giant, jb or any of the other tunes produce - the OP asked about whether or not he can get S3 without an OC and FMIC. Let's stop all the "selling" and concentrate on the original question - which has been answered.

[rader1]

Actually it sounds like the OP is now interest in performance. Which he's not going to get from Dinan.

You were the 1st person to start throwing around performance numbers. The numbers you stated were misleading (others agree with me) and I simple provided more information to clarify your claims. Because OP even stated downpipes in the original post, the Dinan tune would not be the best option anymore. You even knowledged this!

That is why I mentioned other tunes that would not only yield greater performance, but would take into account the DPs and prevent a SES/CEL getting triggered on his dash.

[sickem]

Actually the dyno numbers are misleading. Remember that Dinan takes so much money out of your wallet that you are lighter. In addition, since you cannot afford to eat you will lose weight which will increase 1/4 miles times! I know, I'm a funny guy and I'm sure I'm the first one to use this joke.

But seriously, if you're not concerned about warranty considerations OP there are other options that are considerably cheaper that will maximize your mods while still being PnP and safe for your engine, as others have already mentioned. It is just something to consider. If you're stuck on Dinan, then I guess the thread's already answered your question.

OP go get an IC, cldp, and and exhaust, then get a jb+ and you will smash any Dinan S3...
I went to the dealer to get S3 and the rep at th e dealer said its not worth it when you can do more for much less. But to each his own if got it splurge it....

BX TT3,

Obviously you like the jb+ stacked over the Dinan S2 based on what I read. I've been thinking about the same thing of late. Can you give me some sense of the combo in daily use as compared to just the Dinan flash?

With the S2 do you run the jb+ at the stock setting of 2.75psi? And I take it the addition of the IC is a must at these stress levels? Fortunately(or maybe unfortunately)as for the exhaust I rather like the sound of the OEM e92 pipes.

thanks,

It's an exhaust mod, please explain

Other tunes make use of the free flow pipes and push the turbos a little harder. Dinan does not.

Compared to the dinan flash it going from stock to dinan stage 1, but that is because i keep it at the minimal setting. There is also one made specifically for flashes that adds less psi but i opted for the regular one. Furthermore I wouldn't recommend you do this unless you are full bolt on, the less stress the better. You would most likely need to go with dps at least with and secondary cat delete and exhaust upgrade later. btw there are exhaust that are close to stock sounding while giving you more power...
Search the forum a couple of years ago there was a guy who did the dinan an jb+ and had some issues it was a 135....
