It's just a number, other than a 1/4 drag race, where are you going to miss that 10-15 whp? Most "trackers" here find the stock 335 power more than adequate. You really have to drive a Dinan flashed car to appreciate it.

Hey Jim, see what you can scare up. There probably are AWD dynos here in Sask, but you have to hook a tractor up to them.

It would be nice to get a dyno in when I'm there because, though on different cars, we might get a look at the difference between Stage II + FMIC and Stage III + FMIC.

Terry - I'll let you and Glenn know. I'm not sure that having a dyno run within 24 hrs of flash will give you accurate results (I think the ECU needs some time to adapt).

Hey Guys, Here is what I got out of my XI "Stage II" Dinan power wise. That was on a Mustang Dyno.

http://www.e90post.com/forums/showthread.php?t=133625

I know Bubbles got some better numbers, but unfortunately I don't believe he has a "pre-flash" dyno. I'm still waiting for more dyno results from others with the revised flash, we shall see....I'm not going to get it.

Someone is claiming on 1addicts that his friend with a 335i has a turbo failure due to the Dinan flash.

Thread seems to indicate no turbo damage, but some form of fuel combustion issue.

I hope this is true that it has been cracked and released soon

The AFR on that dyno chart is too damn rich from 5000 rpm on. The AFR is 10-10.5:1. That is way too rich even when more boost is added at the top end. If the AFR is leaned out to about 11.5:1, then there is power to be gained at the top end. The N54 is a direct injection engine and does not need to be run that rich to be safe.

[vegasspeed]

I don't get all these people bashing the $2k stage two tune for the money. That is a good deal. So what if a Juicebox puts out a little more hp. The Dinan team is full of engineers and the back your car for 4 years after you install it. The warranty is HUGE people. Understand that most car companies don't want you to push the limits of a car's engine and then comeback with a blown piston and tell them to fix it. It doesn't make sense for BMW to support all of the crazy stuff we do to the cars. IF your car is still under warranty than don't do any stupid stuff to it. It is plain and simple but I see there are some people here that just don't get it.

[StarrDlux]

mips? you mean DME isn't a CR167 "class" processor? hmm. good to know.

Stage 2: 384hp@5700rpm / 421lb/ft@4300rpm
Stage 3: 398hp@5700rpm / 429lb/ft@4300rpm

*Result is for Stage 1 + free flow exhaust

But Stage 2 with free flow exhaust: 392hp / 429tq. Same torque as Stage III and only 6 less hp for a lot less coin.

You would have to spend $2800 more for add'l 6hp if my math is correct:

If you already have Stage II, incremental cost for exhaust = $1700 + labor.

vs. incremental cost for Stage III = $4100 + labor (OC & FMIC and incremental price of Stage III flash)

$4100 - $1700 = $2400

I just can't rationalize $2400 for an extra 6hp until Dinan puts out some dyno graphs to see where the extra hp & tq are coming from vs stage II w/ exhaust (they have this dyno chart in the original news release). Hell, I don't think I can ever rationalize it... granted, you're also getting the added saftey of everything running cooler with Stage III but c'mon... $2400 for 6hp?!

Add the labor difference between simply getting the exhaust and stepping up to Stage III... the difference becomes $3700!

EDIT: sparkplug correctly pointed out the 392/429 quoted in the Dinan press release is with the full Dinan exhaust (includes a race only x pipe they don't sell yet). So the difference is probably a few more hp and tq.

I assume you are talking about my dyno. There is no AFR on the chart. That's turbo boost pressure......

No, I think he is talking about the dyno chart that I posted for attorneyscott. Yeah, the dyno shop mentioned that is was running a bit rich and probably leaving some power on the table.

The warranty is a plus, but let's not get too carried away. You're essentially trading your BMW factory warranty for the Dinan warranty, and paying for it to boot. If Dinan ever filed for bankruptcy, not only are you unlikely to ever see warranty work from Dinan again, but your BMW warranty would have already been voided long ago. So, in essence, you would have no warranty and be out thousands of dollars.

Some people are comfortable with that, but for me personally, that's not an option. That's the beauty of BMW Performance Parts. I see so much bashing of the price of those parts, but few seem to realize your original 4-year BMW factory warranty covers the part. To me, THAT'S true peace of mind.

Of course, the parts offered are limited and there is no BMW reflash as of yet, but if ever does come out, I will be all over it for the above reasons.

Yes, you are right, it is big money to pay for a small increase in HP (according to Dinan). However, after putting a few more miles on in my Stg. III I believe that while *peak* power may not have been greatly increased, the way power is delivered thoughout the band has been changed significantly. More power is available everywhere and much quicker than before. The car really feels like a NA small block V8...as strong as a C6 Vette in the mid-range. Just my butt dyno experience, of course. Real dyno to follow late next week.

Nobody has gotten the flash yet with catless / high flow catted downpipes? I'm sure this could have a great impact on power.

That kind of defeats the purpose of going with the full Dinan Stg. III. You accept the fact that you will pay more and have warranty...No Dinan guys I know would be willing to compromise thier warranty to put a set of DP on their car. About aggressive as we are gonna get will be the Dinan Racing Exhaust (mid-pipes)...

Add the labor difference between simply getting the exhaust and stepping up to Stage III... the difference becomes $3700!

According to the Dinan site, the 384 figure is with the free flow exhaust

The results of Dinan’s Stage 2 tuning are nothing short of breathtaking, with the added boost and related recalibration, along with the Free Flow Exhaust, producing maximum output of 384 horsepower at 5700 rpm and 421 lb-ft torque at 4300 rpm.

So the hp difference is more like 14.

The advertised HP increase for adding the FMIC to stage II without getting the Stage III software and Dinan OC is 5 HP.

The intercooler may be installed in conjunction with Stage 2 Performance Engine Software as well, producing an additional 5 horsepower as well as more consistent performance under varying driving conditions. The improved thermal efficiency will also enhance turbocharger reliability. The intercooler may also be used with other manufacturer's tuning products, however the matching new car warranty coverage does not apply in these cases.

I'm getting the FMIC because I think it is well worth it and seeing how hot my car runs. It's that OC that makes the step to a full Stage III so expensive. Even the the net gain is only 9 HP going from the Stage II.5 (i.e. Stage II + FMIC), the software cost ($500) would be well worth it because you getting a map to fully take advantage of the FMIC. And as Sniper points out, it is where and how the extra HP is added that makes the difference.

That''s what I would suspect (and why I mentioned it would be helpful if Dinan supplied some dyno's)... the hp & tq curves would have to be improved for that kind if investment. Thanks for your butt dyno... looking forward to seeing the real one too.
