[JY335i]

So here's the story in a nutshell...
I was debating on buying software for my 335i but was worried about warranty. So after looking around at all the other companies offering tne same product, I went ahead and purchased the dinan stage 2 software for tripple the price to be safe with warranty. Well after I got the software they had the issue with the automatic cars so I was without anything for two weeks. Then I finally got the new software that was actually supose to work in the car and I decided to get together with some friends and go to the dyno. Well not only did every other software dyno better then mine but the dinan software isnt really what they say it is. My car dynoed at 307 to the wheel which is around 365 to the crank after the 18 or 20 percent loss. I called dinan and they said go to bmw to get the o2 sensors checked out and mabye that's the problem. So I did that and everything is fine. I called them to get a refund since they misrepresent there product and it is not 385hp. They are trying to tell me that due to the fact that my car is an auto that it could loose more power then a stick which I can understand but not 20hp! So right now they are not refunding my money and are going to talk to steve dinan about the situation. For those of you that have the dinan software I recomend you to go and dyno your car so you know what power your car really has and not what dinan is stating and for those of you considering dinan over other companies, well in my opinion you should reconsider due to the fact that I just spent $2100 for when I could have gone and got some other companies product for a third of the price and put out more power.
Hopefully I'll hear back from dinan tomorrow and see what they have to tell me.
I'll let everyone know what happens once I hear back from them.

First off drivetrain loss is 15% not 18-20% so your crank number is even lower. This is confirmed BY DINAN themselves. Second the autos in 335s have the same DT loss as the manuals.

Third Dinan always puts out low numbers.

thanks for the heads up and sorry that happened to you. please type slower, it was difficult reading your post. oh and do you happen to have the latest software? did you just get your car? that could be why.

I had no problem reading your post. Good luck w/ Dinan, and I hope you get to the bottom of whatever is happening.

Thanks for the heads up,I was considering getting the stage II Dinan tune.I think I will wait to see what happens.

Well, what tune do you think you can get that will have the power you want AND the warranty you desire???
I don't think you have much of a choice unfortunately

[Ryan@Motorwerks]

Could just be that the dyno reads low...

Can you tell us what numbers other cars put out and with what mods?

[garyhgaryh]

If you did some research on this board you would know that the dinan tune puts down about that much HP at the wheels. Dinan advertises their HP at the crank while the rest of us measure at the wheels (ala dynojet).

[vegasspeed]

Is it at all possible that your numbers were low since it is hot & humid in Florida right now? I notice that you didn't post your conditions of the dyno run. If I did them right now in Vegas i wouldn't expect anything great right now. Post the numbers associated with your dyno so we know the whole story.

hmm very weird.

As others stated, can just be a dyno error.

Which dyno machine did you use?

[Bubbles]

Is this a joke?

Third Dinan always puts out low numbers.

FYI -- 307WHP is ~ 361BHP to the crank...307 / 0.85 = 361.17. So, FWIW, I think his Dinan 335i is closer to the advertised 385BHP, although 24BHP lower. Either way, everyone knows that the Dinan ECU Flash for the 335i does not provide similar increases in HP/TQ as other currently available piggyback 335i tunes.

[Spazdoc]

So, in order to comment intelligently, we need the following information:
1. How long did you allow the new Dinan software to break in before dyno?
2. What were the numbers that the other cars put down that day?
3. What were the mods of the other cars?
4. What additional mods do you have?
5. What type of dyno was this?
6. Did you realize, by doing the research of all the debates on this forum, that the Dinan puts down a little less power than the others?
7. Are you running progman 29.2?

These may answer some questions.

What are you even talking about? You just disagreed with what I said, while saying almost exactly what I said.

[garyhgaryh]

Guess it depends on what loss factor you are using. 20% loss would be about 384 rwhp. 18% would be about 374rwhp. 15% would be about 361%.

Just realized that myself. Either way, his Dinan tune is what it is.

[funkdoc]

You have to remember as stated by Dinan, they use 85mph cooling fans and an engine dyno and dynopack to calculate their numbers on 93 octane. Therefore, their horsepower claims are in the most ideal situations. I dynoed only 274 whp on an awd mustang dyno with intercooler,catback, and stage 2 but I'm not fazed by the numbers because the car feels very good and I hit 12's in the quarter mile with just the flash. Many factors could've contributed to the low numbers and the auto tranny is one of them. Don't fret. If you wanted max power, should've got a different tune and such.

I had the software in for two weeks.
the other cars with active software Vishnu and procede put out anywhere from 15 to 20 up more.
the other cars have the same mods as I do. ( just software)
this was done on a dyno jet.
No I am not on 29.2

Hopefully this answers allow your questions.

Thank goodness we have sflgator, Ocha and Ocha's midget to steer us straight.
