[BQTuning]

After painfully waiting and planing and working with many people who believed in what I was doing, I now have the very first 335is with Dinan Stage 3 Boost Upgrade, FMIC and FFE.

I have a dyno appointment this week and will post the result just waiting to ride in over 100 miles for the DME to adapt to the new changes. I am starting this thread early until results come back.



Hung out with a stock 335is and a 135i running JB4 map 5 this evening after about 50 miles with the new Dinan tune. Had no problem leaving the stock 335is behind but the 135i w/ JB4 map 5 gave me hell. He would always pull to the front by a car's length then i would hold on then started creeping up to it in the tripples


************** Update ****************

Went to the dyno shop on 09/30/2011 and got 340 whp and 380 wtq which a 17% loss on a dyno roller. According to Dinan there is a 12% drivetrain loss with stage 3 that should be about 360 whp and 400 wtq (Please see post# 25 of Dinan response)

Bro you need downpipes, just take them out before service, you will fucking gain !

you've got a pair of brass ones racing modded 135I's

Congrats!! For now, you also have spent the most in power mods.

Looking forward to seeing your dyno results. What kind of numbers are you expecting?

Dinan claims it has not changed anything with the IS version with the N54 Boost upgrade stages. As by using the example of the already Stage 2 for the IS which replicates the stage 2 for all N54 335i boost upgrades, I would assume that the IS Stage 3 boost upgrade will follow the same footsteps as my former stage 3 boost upgrade on my former 07 E92 335i.

98 More Horsepower / 129 More lb-ft of Torque
Stage 3 Performance Engine Software safely increases turbo-boost pressure and is optimized to take full advantage of the High Performance Intercooler. The boost is tapered at the higher levels to keep from over heating and damaging the turbos. With a peak horsepower of 398 at 5700 rpm and the peak torque of 429 lb-ft at 4300 rpm as tested with Dinan High Capacity Oil Cooler System and Dinan Free Flow Exhaust is a monumental increase over the stock 300 horsepower and 300 lb-ft of torque BMW quotes.

The Dinan OC of course is not needed on the 335is Now the numbers cliamed by Dinan are crank numbers and not wheel numbers so we have to add the correct formula to this.

BMW claims that the 335is is 320HP at crank - 15% average loss = 272 Whp

Dinan stage 3 boost upgrade promisses 98 HP gain - 15% average loss = 83 Whp gain

272 Whp + 83 Whp = 355 Whp is what I am looking for or above on the dyno tomorrow

ure in s. fl. right? would love to check the car out and see how it does against my procede tuned 335is.

[trickcruiser]

In for the Dyno results.

So are you an auto or manual? I have been hearing issues with the DCT with power upgrades and was wondering what Dinan would do about this.

Did you get a dyno run in before the software/intercooler upgrade? Would be nice to see a before and after as each car and dyno read differently.

Anyways, good luck tomorrow!

Actually, your theoretical numbers for the stock 335is are a little low. Its more like 293whp:

Here are the driveline losses calculated by Dinan. Just can't remember if the car was AT or MT.

I have couple of neighbors that have PROcede on their 07 E92 335i. More than likely I will be doing some pulls with one of them on their map 1 and/or 2 (no Meth) that will give an example of some sort.

Why arent you on Beluga app ? Lots of us here in S FL use this to communicate with each other for meets etc outside of e90post . Download the app and look for FloridaBimmer hosted by Martin. Get the app and we can hook up for some pulls

Not exactly theoretical. The 15% percentage loss is the "commonly" used calculation to give the minimum results regardless of weather conditions based on transmission type

• MT is rated at a common/ average loss of 15%
• AT is rated at a common/average loss of 20%

I placed DCT under the MT average rating since we do not yet have a standardized rating since BMW has under rated the HP specs on the 335is per some sources.

Also, temperature plays a big role in those numbers you posted which are not disclosed. Was it a mustang dyno or dyno jet ?

I would rather use the worse case scenerio so when I do take it up with Dinan there will be no room for conditional excuses.

This had to be MT drivetrain loss calculations. Dinan N54 test car on boost upgrades was a MT. I hope their drive train loss formula is true i will be a very happy guy tomorrow.

I'm glad your all sorted out now. When are we hitting the track again? Might go Friday night if you want to go.

LOL, dang bro where you bin ? Why arent you on Beluga ? You need to get on their so we can keep you up to date with meets. Danny is suppose to be hosting one on Oct 1st after Martin's rally.

Weather looks iffy for tomorrow. It look like 73 degrees tommorrow night. I am tempted to bring the IS out there. Keep me posted but first get on Beluga

I've been around, I just helped out Danny with an install last week. I just linked the Beluga thing to my facebook. I'm part of the sofla bimmer group. I just have to figure out how to use this thing now.

I'll still go with automobile magazine's dynojet numbers over your own. You needed to do a stock dyno on your 335is, before the post flash dyno. Since you didn't, we don't have a baseline, and you can only speculate on the change in whp.

Here is a dyno on the 335is, in the sweltering heat of florida (I know its an std dyno, but its still more in line with the automobile mag numbers):

PO Updated with some results. Going to the track tonight and will post 1/4 time results

Thanks for your help on this. Technically this will help me out so I can have Dinan to correct this issue. Those dyno results confirm what san6279 posted on Dinan's drive loss calculations.

[san6279]

This was also on a Mustang dyno, which by my understanding reads a little lower than say Dynojet and others (by how much I'm not sure). I made the same "mistake" of not getting a pre-tune dyno...the only real way to tell what your gains were. Let us know what Dinan says on this.

I think the stock dyno results are sufficient to confirm drivetrain loss on the 335is .

Those dyno Dinan numbers do not look like Stage 3, it looks more like Stage 2 that got flashed on my car.

[tscdennab]

If that dyno is well calibrated, your results are very good. I got 356whp with GIAC Stage 2 Race and 332whp with the regular Stage 2, with a baseline of 250whp. And I have no cats.

But some Mustang dynos are calibrated to read high, like Dynojets.
