Hey I spent the money on Dinan and ran it for over a year before going to Cobb. Dinan is by far the biggest waste of money I have ever spent on a mod.

Do not fool yourself Cobb and Dinan are Night and Day from one another.

Quality not. Do a search for Dinan in any of the forums I am sure you will never see man I switched from X tune to Dinan man it is so great.

You will find multiple posts where people switched from Dinan to another tune and realized wow I wasted money on Dinan what a joke in comparison in performance.

I was one of the early Dinan adopters. After my warranty expired I went to Cobb. I won't hesitate to go back to Dinan, however, once I get my M4 whenever it comes out and while its under warranty.

I thought the Dinan tune was a good tune in the sense that it was smooth seamless and had no issues with a good boost in performance. It was a good all-rounder. It also tries to keep the engine cooler by driving the water pump faster.

Most people fall into the trap of thinking that more aggressive = better when it comes to tunes and that just isn't the case. Dinan could turn up the wick too, if it wanted. But backstopping BMW's warranty and having the tune installed at BMW dealerships results in a more conservative tune.

A plus for some - dealership installed, forget about it, one size fits all - is a huge minus for others. So once my warranty expired I entered into a whole new world of options and performance with Cobb.

That handheld device with all it's choices, maps, updates and ease of use is killer in my books. So is the screaming performance. The support is phenomenal too.

So Dinan is a good option if you are concerned about warranty and aren't looking at setting a dyno or 1/4 mile record. In spite of what people say, it still transforms the stock 335 with a large increase in performance.

If you want more and aren't worried about warranty, then go Cobb. After three years with a S3 Dinan car, I threw in some downpipes, got Cobb and it's like I am driving a new car.

I have dinan stage 1. i hate it becuase one i cant go to stage 2 without paying another 700 plus 2000 for an oil cooler. also. i dont think dinan has a built in downpipe fix (correct me if im wrong). How hard is it to go from dinan to cobb? and diy out there?

No DP "fix" on the Dinan tunes, since they're CARB legal, and deleting cats is about as CARB-illegal as you can get (among a thousand other things). You should be able to install the Cobb tune right over any flash tune, right? Or do you have to get flashed back to stock?

If you're not under warranty, find a shop with an Autologic for BMW and get them to flash you back to the latest stock DME software (I have one). Takes about an hour (from pulling into the shop to pulling back out) since the BMW flash process is VERY slow. If you are under warranty, take it to a BMW dealer and have them do the DME update. Warning: They will have to update ALL the modules - can't do a selective update - which can take all day! So plan on leaving it with them.

Maybe start a new thread? This one is a bit old and talks about boost oscillations with Dinan, not specifically installing Cobb over an existing flash upgrade.

BTW - I have Dinan Stage 3, and I also have the boost oscillations. I was going to call Steve to see whether they have any kind of fix. However, before I condemn the tune, I am going to check everything on my end, first, especially any boost leaks or leaking diverter valves. Already have new injectors, coils, and plugs, cleaned intake ports every year for 2 years now, readjusted WGs on 68k mile old turbos, and stock everything minus what I listed in my sig. Mine is a very early July 2006 build.

It's a flash tune, not hardware.

I had and still have lots of Dinan for warranty paranoia, but if I had to do it again Cobb (its amazing even though my car is being a prissy btch at the moment) or JB4 hands down. You are quite confused if you associate Dinan price as quality. And given the nightmare I just went through on other part installs I can't even recommend them over parting out a build for suspension, and other parts.

*Also the 335i tunes from them aren't even their most expensive

You can't insult people by saying you can afford x over y when that isn't the case and then expect everyone to respond perfectly. I tread carefully around here as it is with dinan parts , you just threw red on yourself and ran around the bull pen.

But ...but what about their cool badges?!

Your car came with no oil cooler ? Your better off where you are at then. It is very easy to go from Dinan Conn, just take your car back to dealer and have them flash it back to stock before flashing the Cobb AP. Complain about the osscilation.

The reason why I am saying to have the dealer flash back to stock is to make sure every bit of the Dinan is removed whereas the Cobb can flash over it but may not be able to remove ALL traces of the Dinan on the DME which may have an impact on teh Cobb performance.

Btw get yourself an oil cooler

Nothing, that exactly what they are going to do and give you an excuse of its the BMW software which is BS. They are not going to update the software as teh N54 to them is a dieing plateform and will not waste resorces on it.

I been down this avenue with them plenty of times with Stage 2 and Stage 3 on both E92 cars ie my Previous 2007 335i E92 and my current 2011 E92 335is (which use to be on this car)
