If a Dinan ECU flash becomes available for 335i

Could it be a better way to go than an Xede, since it will be warrantied by Dinan? Could it produce a similar performance improvement?

Uh...yeah, good luck with that.

btw - Dinan only just recently came out with a few perf. mods for the E90...exhaust, throttle body, and an intake; no chip. You might be waiting a while for an ECU s/w update for the E92; and even so, what kind of gains will it show and for how much $$?

If it's available, then most likely it'll be warranteed. Could it produce a similar performance? who knows? unless someone close with Dinan can provide some info, otherwise it's all speculation

More $$ for sure...but

I had a bunch of Dinan work for my 99 M3, it was great. I agree the warranty issue would be resolved, but they(Dinan) will most likely sacrifice some performance to gain reliability. I'm not saying Xede is not reliable, I am saying they will probably err on the cautious side since they are risking some expensive repairs. And of course other than hamman, they will be the most expensive. It depends on where you put your emphasis I think. Of course the Xede is something you can resell when you get rid of your car, whereas the $400 I spent on my old M's ECU flash was useless when the car went back, so that makes a pretty good argument for Xede especially since it will be cheaper initially. I could sell the other pieces from my M3, but software is something you're stuck with unless you can find someone willing to swap ECU's and I'm not even sure that's a good idea these days. Despite all of that, my money will go with Dinan, I have a history with them, and the things pretty quick to begin with, if I could pickup maybe 20-30HP, I'd be happy. Again it depends on what's most important to you, there will be people here who will argue one way or the other, but the weight you put on things like performance vs. warranty is the true indicator. Good Luck.

I have no first-hand experience with all this but from what I've read I feel like Dinan won't go all out, as 13307 said above (sacrificing performance for reliability)... if they were to come out with something, based on past history (is there such a thing as future history? :P), do they avoid so much of a power increase that makes customers need to upgrade wheels etc.? I don't think they would... like wheel spin, etc.

Considering Dinan has a marketing/sales/installation agreement directly with many BMW dealers, BMW wouldn't want a "Dinan" 335i to get that close to their new '08 M3 in terms of power and performance. This would steer many ppl to this option instead of the M3 which should have ~ $10-$15k premium over the 335i; hence, BMW would lose sales and profits from the new '08 M3 to a less expensive modded 335i.

how much has a dinan ecu flash cost in the past? is it more than a XEDE? I thought an ecu flash was cheap, since there is no hardware...

IF they do it, then the issue will become the M3. but either way, if they do it, they will provide a warranty, however how much they are gonna back it up is a different story.

i simple flash is the labor from the outfit performing the flash and the purchase of intellectual property (the software). its not gonna be that much cheaper

Yeah, and I'd be surprised if they gave it > +20HP/40TQ. Anyway, as of right now, it's "vaporware."

so why is everyone saying that DINAN will be more expensive than the xede? even if DINAN doubles the price from their e46 offerings, it will still cost significantly less than a XEDE

So the real question is... is it coming out, and will it suck?

Well, the OP asked about a Dinan chip as opposed to the Xede...the Xede is currently only available for the FI 335i.

because with the previous dinan software charges it was a charge for labor and the intellectual property. there was no physical controller to be purchased. valid points, when it comes out its gonna be more expensive if its done the same way. my guess is $2100

People, don't forget that we are talking about a FI 335i, which is much more easier to mod than previous BMWs...but the issue with the new M3 still remains

Yep, with a re-flash you are stuck with it. Although I can see a possibilty that a re-flash, if tuned properly can achieve what the Xede does (I'm not an expert, just making basic assumptions). Another advantage to the Xede, along with the fact you can remove it, is that it can hold two seperate fuel maps which can be toggled back and forth with the proper hardware.

Assuming if the re-flash can be close to Xede levels, it will be the best bang for the buck performance option you can get for the 335i.

FYI, as of about 2 months ago. Dinan didn't even had a 335. This coming from our regional rep.

I asked him "there are companies out there that are very close to having a working software upgrade for this car and you guys dont even have the car yet?" He could not answer my question.

Ive heard rumors that bmw will be developing their own performance program and they are not going out of there way to support dinan anymore. This would give good reason to why dinan lowered ALL there pricing several months ago.

I also called about a couple of months ago and they did not even have a 335i yet whereas others already had theirs. I asked a few questions and all the guy could do was say "I don't know". Needless to say I was not impressed!

Same experience with Dinan, which is why I followed Shiv's Xede the whole way through and then hopped on the bandwagon in a hurry! My feeling is that Dinan dropped the ball, bigtime...it's like the 335i wasn't even on their radar.
