so how can we confirm this myth about the data logging ECU on Mar 1+ 1ners? Mythbusters possibly? If this is true, looks like Dinan is the way to go since mine was built after then to get the beige interior.

Just as a fair warning, please be careful with these power mods. If you have more than one car and don't mind the potential problems / downtime then I am sure it would be fun to have.
Personally if and when I decide to get a 135 or 335, the first thing I would put in would be a LSD. Chances of having warranty related issues with that is going to be alot lower, plus it allows you to actually put the power you already have down. I am not sure what has happened on the E92 boards with Vishnu, but either people treated him like a God or they had problems. Which one is valid is up to you to research and determine... |

I mean getting new maps added to your piggyback. They send you a new one, and you mail the old one back.

Expect to spend a good 3.5k get get an LSD in this car, perhaps more. I've heard numbers upwards of 5.5 on the E90 boards.

e-diff works a lot better than I thought it would. Got autocross in 10 days, to find out for sure though. I know the bugger will power thru sweepers, where the e9x would toast the inside rear tire, with all nannies off. |

Procede has good numbers, but the most complaints period. You can spin it all you want. |

- Warranty - True computer reflash through OBD-II port - Doesn't just confuse factory ECU - Controls boost, fuel, timing, cooling system - Doesn't have thermal problems of other tunes I would bet a lot of money some of haters would stop if it didn't cost $2k. Dinan software is the real deal. |

Dinan is nice for the warranty, but I don't see anything else you listed as a real advantage. True reflash through OBD2 port means that you can't sell the tune when you sell the car. Piggybacks my work by "confusing" the ECU, if one chooses to put it so simply, but how is that a disadvantage? Adding a piggyback doesn't take away any of the functionality the ECU already has, if it's programmed right. Instead, it adds many, many more options in terms of tunability, versatility, and additional capabilities. Also, I really haven't heard of anyone having any more or any less cooling problems because of a tune. The Dinan tune increasing water pump duty cycle is a nice touch. Basically, they add a low-temp thermostat for you, but given that most of the N54 cooling issues have been related to oil rather than coolant temperature, I'm not sure how big of a difference it will make. I don't mean to sound argumentative. Dinan is a very nice tune. However, the only real advantage it has over the high-end microchip piggybacks is that Dinan will warranty it. The disadvantage to this is if you use any non Dinan aftermarket parts, your warranty is shot. In other words, when my car gets here, I can slap on my RR catless DPs, along with an FMIC and Procede, and end up with 400rwhp that's proven to be quite reliable. That's M5 or C6 fast, and it can be had for $4k with installation. That's about the price of a Dinan flash, and oil cooler minus laybor, that will net you about 80hp less at the wheels. My guess is, a Dinan package with that sort of power (what they'd call 460hp) would cost more than $10,000. I'd figure $2500 for flash, $2000 oil cooler, $2500 for intercooler, $1300 for axleback, $2000 for downpipes. They might even require more nonesense, like a $1000 intake, or sell it as part of a $22,000 package like the S2 335i in this month's Roundel. You kept your warranty, but the amount of money I saved means that I can replace almost anything that explodes, short of a new shortblock. $6k+ is easily custom built forged internals, assuming the absolute worst. The only issues I've heard of on any cars are toasted wastegates, which happens stock, and excessive oil temp, which hopefully won't be an issue with the stock secondary oil cooler on the 135. Mods please feel free to delete this if it's too off topic, but I wanted to put in my two cents (ok, maybe more than two cents) worth on this. There seems to be a common perception that a reflash like Dinan is patently superior just because it's a reflash, when this simply isn't true when you compare it to a good, high tech micro-processor controlled piggyback. Dinan is a great option for someone who wants to pick up an extra 60hp or so and keep their warranty, but it really doesn't offer the richness of features, customizatbility, upgradeability, or potential that Procede or the other high processor power piggybacks with digital I/O do. If one is happy with 320-340whp, and never wants to touch anything again, it works GREAT, but if someone is bitten by the mod bug, a good piggyback like procede is the clear choice. If I were deciding between a Procede v3 and Dinan Flash as my ONLY mod, I might go with the Dinan flash, because it wouldn't be THAT down on power, you don't need all the features v3 has at that point, and the warranty from Dinan is nice incase you get real unlucky and something goes wrong. However, given I plan on doing a good deal more modding than just a tune, a piggyback with the flexibility of Proced v3 would be a better choice. That way, I'm not limited in terms of who's supporting mods I have to buy. I'm quite sure the RR DPs are superior or equal to whatever Dinan will come up with, and probably 60% cheaper. If I wanted to use them with my Dinan flash, bye bye warranty. For intake work, I often custom build, because it's pretty easy to mold some fiberglass, and use it or PVC for ducting, combined with a high-flow filter. However, if I were to do this with Dinan, bye bye warranty. If I feel like paying less than untold thousands for an exhaust, bye bye warranty. Since I plan on doing reasonably substantial mods, something like Procede just makes much more sense for tuning. You pay the extra money for Dinan for the warranty, but if you plan on doing even a BPU level of modifications, you can kiss that warranty goodbye, or you can kiss 10 grand or more goodbye if you do it the Dinan way. I want to make it clear that I have nothing against the Dinan tune, or people who buy it. It just isn't the best option for me, and seeing as this is a Procede thread, I don't see the harm in pointing out that a sofisticated and well tuned micro processor controlled piggyback is an excellent option for those that want to go beyond the 'chip only' level of tuning.

very good point and there have been people caught in the middle with Dinan saying its not our responsibility and BMW saying it not their issue either, leaving the customer with a "full warranty" high and dry... Now this does not happen often but it has happened.

I believe the Helix is sold directly from the tuner http://www.helix13.com/bmw/products/engine-intake

Though I do understand what you mean, you either have the unit there with you and they change it for you or you swap units with different maps. I do understand that being a pain. The ability to switch maps & the fact that I have not heard one reliability issue with the Attaché has me sold for now. Have them keep you at low boost/stock for your daily grind, and on those sunny days flip the switch and you have a whole new animal. I will be stopping in their shop hopefully on Thursday. See if I can have someone there post some info up on here or if they want to give me the inside scoop. |

the only other mod I had on my car at that time was a front aero lip... I am not trying to spin anything, just sharing facts from my EXPERIENCES. And LOL at u ppl thinking I am some kind of fanboy and/or have some kind of stigma because I have an E92 and a member of e90post.

I was using Helix as an example in this case because they currently have all the nifty stuff that Vishnu is planning on adding with v3. I'll edit my post to make it more clear. They should both be pretty darn equivalent in terms of functionality when the new firmware/harness for Procede is available. Maybe we can move all the Dinan vs Piggybacks stuff to a different thread if it's casuing clutter? I thought it wasn't a terrible place to talk about it, given that one can draw some pretty clear contrasts between it and Procede. As in most cases, it's a matter of pros/cons rather than good or bad. Though I will personally go the piggyback route, Dinan would be a better option for many people. I just get the impression that some think it's superior for all purposes, and I don't agree with that.

I couldn't care if you belong to e90post or have a E92....I can only comment on what I read here--and in this case it seems to be that you are deeply passionate about Procede, Vishnu etc. and don't care to accept that other tuners may have superior products or the fact that Procede *may not be perfect* |
