I see. Well, now it all just comes down to whether or not they are telling the truth, and I'm not up for calling anyone a liar, especially with the myriad of factors that could be causing your car to feel "down" on power.

And yes, I realize you claim that you felt the power "loss" on day one.

And I wasn't saying that you were comical, just the notion of wanting a complete refund because you perceive there to be a slight power loss, which can't be officially confirmed. Personally, I'd rather have the extra power over stock after riding stock a little bit after having the flash. Principles be damned.

The people who I have discussed this with and who did get thier pumps replaced had the same comments afterwards. That is 100% fix rate.

The two things you should check. Gas mileage in the city over half tank should be above 16 MPG (you need to covert to US gallons). If you run the car about 1/8 of tank and go around a corner fast or drive up a hill the car will have problems. There are 100+ cars my dealer who been towed in because thier car died while doing this and all passed the fuel pump test with 50% of them have full failures shortly afterwards.

The rev 2 of the Dinan II will pull hard with little or no throttle depression and peaks well before half throttle. My car was never like this before the fuel pump.

BTW, there a reason why Shiv implemented a new safety protocol in the proceed for fuel pumps because all the piggy backs are bypassing the safety portals and a few seconds of starvation will (not maybe) damage your engine. You may want to ask this about the JB3.


Orb

Thanks for trying to clarify things. My gas mileage is and always has been the same since I've had the car... 16-18mpg city and over 26+ highway. It hasn't changed at all that I can notice. I don't thnk putting out over $500 of my own money is an acceptable fix for something that should be covered under warranty.

Orb- WHat were your experiences with Rev1? Did you ever have it? Was your fuel pump giving you problems with rev1 also?

You are right. I would rather have the power too! I don't want a refund at all. I will keep this tune and enjoy it and hopefully just forget how much better rev1 was
I guess the best case scenario would be that my fuel pump will fail and be replaced under warranty by BMW and all my power will be back with the new pump
Until then, I'll just enjoy my REV2 POWER

I can't tell if that post was completely laced with sarcasm, or there was a hint of genuineness in there.

Regardless, I hope your situation works out for the best.

a little of both. But in all seriousness, I will keep the tune and be happy with the extra power I have. It will all work out in the end
Thanks for all your input

I got a tip that revision 1 max PSI was 13.8 and revision 2 max PSI is 13.0

Looking for clarification...

Really? From who/where? Pm me with the info if you care to share, I'd be very interested please

Don't want to get anyone in trouble on that initial TIP.

I will say that I spoke to Brian at Dinan technical department and the target boots rate for the Stage 2 is apparently 12.8 while the target for Dinan Stage 3 is 13.8.

I think that my theory is correct:

They detuned stage 2 to give themselves more room for improvement on the super expensive stage 3 without having to push 16 PSI...

In my eyes, the stage 3 software is probably very close to what the original flash was before their "revision"

This is not what they claim in their press release...

[Wicked_SVT]

I would have to agree that the Revision II feels slower than the revision I. I do like the throttle response in rev II better but feel they did take some out of rev I. I also did a dyno with rev I and Rev II. Rev I I dynoed 320rwhp and Rev II dynoed 308 rwhp. I had nothing but the tune and California 91 Octane.

The only proof that I have that they might have detuned the software between rev 1 and 2 besides the dyno was their advertising.

If you look at the original press release from Dinan it states that the 384fwhp and 421fwtq was done on a completly stock car, NO EXHAUST. If you look at figure 1 in the press release it states "Figure 1. Dyno results for a stock 335i vs. Dinan 335i (software tuning only)". Now the claims in figure 2 state you get 392fwhp and 429fwtq with free flow exhaust. The press release specifically states "Figure 2. Dyno results for a stock 335i versus the Dinan 335i (software, x pipe and exhaust)".

Now lets look at what Dinan is now advertising on thier website for the Stage II rev 2 flash. The description reads "The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related recalibration along with the Dinan Free Flow Exhaust producing maximum output of 384 horsepower at 5700 rpm and 421 lb-ft torque at 4300 rpm*. " So now you mean to tell me when I purchased my original flash we were all under the impression that I would get the advertised horsepower without an exhaust. Since the revision has been released it now specifically states that the exhaust is needed to achieve the advertised HP. Now I am no lawyer but that is a little misleading if you ask me.

[vase330]

I really do not think in all honesty that Dinan stage II is in way shape or form breath taking. Not when we all know what the other tunes have. The only thing it really has is a warranty. I don't intend to keep my car past 50K miles as I have had a lot of issues with it. I can honestly say I don't think I have reliable example. That said, if I ever get another 335 I will assume they have taken out all the kinks, and you can rest assured I will have a tune and it wont be what I have now.

Any lawyers in here???? Class action for misrepresentation/ false advertising????
There must be some way that we can band together to pressure Dinan to either give us a partial refund, or better yet, give us our power back!

You are probably correct on stage2rev1 Vs. stage 3
I recall the boost on rev1 was suppose to be 13.2+(dinan advertised this). Now they changed it to 12.8? WTF, how can they do this and still charge the same $$$???
That is just NOT right at all.

I am working to try to get the original flash back...

Keep me posted please. HOw are you going about this? Is there anything I can do also? I'd LOVE my rev 1 back

[aaronb]

Just to post about my experience- I had rev1. Car was wicked fast. I brought the car in for a lsd, dealer had it for a couple months (long story). In the meantime, rev2 came out, and since they had the car anyway they flashed me to rev2. Got the car back and it wasn't wicked, it was more like "meh". I thought it was in my head, and didn't say anything. Besides, I was too in love with the lsd to care.

After the lsd honeymoon wore off, the car started getting worse and worse, going into limp mode once in a while. Dealer did something (some kind of TSB related to coolant sensor or something?) and limp mode stopped. Month or so later, my car was eligible for a fuel pump recall, so I brought it in and they replaced it.

[new paragraph for dramatic effect]
***HOLY SH!T***
Car went back to being wicked again. It's hard to say if it's equal to/faster/slower than rev1 since so much time had passed. What I will say it was WAY, WAY more than the 2-3% you guys are saying was lost between rev1 and rev2.

I'm not saying dinan didn't screw us. I'm just saying that going back to the original flash might give you 2-3% more power/more boost. But (more importantly) you might also get reduced protection that'll manifest itself as more [additional] power - at the expense of engine life.

I've also not dyno'd the car before, or after to see if there's a difference. I am interested to see what you uncover in your dinan boost research, though. Subscribed.

[GAMEOVR?]

My boost gauge usually shows me peaking at 13.8 to 13.9. Not sure what rev I have, but there is a difference between... stock and dinan... knock on wood I haven't had a problem since I installed it.. and been running it for maybe 10K.

When did you get the software? What are your average temps?

When it was warmer out, I was peaking at mid to high 13psi or so. I saw 14.3 once. This was ~50-80 degrees.

Not that it's colder (~20-30 degrees), I consistently see mid to high 11psi. Definately due to it being colder, might have something to do with the fact that the RFTs don't stick as well in the cold either, reducing load....

There seems to be more and more evidence piling up against and pointing to those pesky fuel pumps by the day.

I am going to the dealer this Friday to see if I can get them to replace the fuel pump so that I can get that possibility out of the way.

Good luck. Be sure to report the findings. I am curious about my fuel pump, I've had the throttle cut out on me during hard acceleration lately...

They wont replace the pump unless its completely dead. I know this sucks but it is the way it is.

I am hoping that maybe my car is one of the ones that can participate in the recall. If not I might have to fork up the $ myself.

Either way, does anyone know what the updated non-problematic fuel pump part number might be???

I don't want to do this for nothing...
