Dinan Stage 3 upgrade for a stock car, should I do it?
I just acquired a 2015 E89 35i, started looking at modding options.
Would it make sense to do Dinan stage 3 upgrade as a first step? I guess there might be different opinions to everyone's liking but what other mods you have done and recommend for a start? Any must haves? Open to any suggestions. Thanks a lot in advance. |

A Dinan flash makes sense since your warranty remains intact with it, but if you start adding other aftermarket mods your warranty is voided. If you don't care about a voided warranty, then a Dinan flash doesn't make sense because there are other more potent and cost-effective tunes out there.
Common mods to start with include FMIC, charge pipe, intake, MHD flash

I went with a Stage II on mine right after the break-in period. If I were still the heavy modding type, I would still have started here. As for me, this is as far as I'll go with this car. It's a lease so it's bye-bye 7/2019. Since your car is under warranty, I would stick with Dinan upgrades as far as the engine is concerned. Suspension, do whatever you want. I've never had dealer warranty issues across three German marques with good suspensions mods. You're in SoCal, there's more than a few Dinan BMW dealers (as well as indy ones) in the OC\LA area. I would recommend, since you're under warranty, getting the flash done at an actual BMW dealership that is a Dinan shop.

See here:https://www.dinancars.com/product/d9...e93-335is-n54/ At current pricing, I have no idea why you would do JB4 or MHD. I would way rather have a flash tune over a piggy-back and I would trust a Dinan flash more than MHD. Just my opinion. Last edited by davis449; 02-22-2017 at 01:36 PM.. |

---------------------------------------------------------------------------------- "I could have sworn I fixed that entry long ago but apparently not… The Z4 stage 3 does not require those 2 pieces. A poor job of cutting and pasting can be blamed. The same stage 3 software is shared with like engines but with slightly different requirements given the engines and body stylings. On the 335i as an example most of the cars did not come with ANY oil cooler and a subpar stock intercooler which is why for that platform those 2 additional pieces were required. In the Z4’s case they came with a stock oil cooler and given the flow characteristics the stock intercooler actual was efficient enough not to NEED to be replaced. Dinan never made those 2 parts for the Z4 because we didn’t see the need to do so." ------------------------------------------------------------------------------------- So no, Stage 3 doesn't require any additional mods over Stage 2, for the Z4. But of course if you have any other questions/concerns about their product you should contact them directly. They are very quick to reply.

I have contacted one of the local Dinan dealers for stage III installation, they said
"Power I would expect about 80hp without an intercooler" Anybody can chime in if that would be the case. |

The point is, do the flash you want to do, but don't worry so much about it. It's all about the drive and peak numbers never, ever tell the whole story about how the car will perform. Taking your Dinan dealer's word at strictly face value, III isn't worth it in either of our cases. |

If you're going to get rid of the car after the lease you can always sell the MHD with ease. And in regards to the intercooler just know that the e89 has an overheating issue and will go into limp mode even on a stock tune. But if you're only going to push the car once in awhile it shouldn't be a problem. If you tend to do some spirited driving it maybe worth the intercooler upgrade.

Go re-read my post. I indicated that when it comes to flash tunes, I would still prefer a Dinan flash to MHD. Never said MHD wasn't a flash tune.

Look at my signature. I'm heavily modded and still go to the dealer for warranty maintenance. My dealer is good about that.

Honestly I skimmed through the thread, knowing that you've got a hard on for Dinan. I'm also happy to see how butt hurt you get over this trivial stuff. Enjoy you're over priced tune, glad you'll be leaving the platform once your lease up...
