Hi everyone, my name is Jake
I am the proud new owner of one 2007 335I and I am so excited!!! I took my new ride and had it dynoed a few days after I received. Just like BMW said, it read 300hp and 300 ft. lbs. of torque. I am very pleased with the car but it just didn’t seem to make enough power, at least not for me. I spent a lot of time searching on the internet and calling around to find someone with performance upgrades. The only thing I found was a piggy back unit where you have to cut the wiring harness, which of course, is out of the question. I am in Miami and ended up talking to some people locally and was told that there was a place called Proto Tech in Fort Lauderdale that had computer chip upgrade for the factory program, apparently they are a well known Porsche tuner.
So, I called them and spoke in detail with the owner there and with a bit of apprehension decided to take my baby in. I had been told buy a bunch of well known bmw tuners that the factory program could not be modified. Anyway, they called me in about two days and told me it was ready to pick up. I picked it up and headed straight to the highway to test her out. To my delight, as I rolled into the throttle and proceeded to get pinned in my seat, I was amazed. My car was transformed into a little speed demon. I was so happy I scheduled another dyno run and took it in. The results were 61.23 more horsepower and 71.26 more ft. lbs. of torque. WOW!!!!!!!!
I am so excited that I just wanted to get the word out!

Dyno chart please.

I can't seem to post it, don't have permission? Anyway go to photobucket.com and my album name is realbmw, so do a search for realbmw then click on where it asks if you are looking for user "realbmw" , it is the only image I have posted.

I will post it for you. Do you also have the "before" dyno graph? I believe your gains are not what you think. This "after" graph is actually just ~20-25 HP/TQ more than others have seen from their stock 335. The BMW specs are under-reported anyway, the actual flywheel HP/TQ stock are much more than the published 300/300.

Thanks aftp302! I posted my before dyno in the same album. It is not in color like the first because I had the dyno facility fax it to me because I lost the original but it seems to be clear enough to read.... Thanks again!

Here is your "before" graph. Looks like you gained about 25hp and lost 3tq at the wheels. The torque loss is probably just a difference in dyno runs. Not the best results we've seen, PROcede provides must better results (50hp/70tq) for $1300.

I looked up PROcede Vishnu's dyno runs on dragtimes.com and printed it out and I am going to ask around and see what the numbers mean. Mind you, my car was totally stock and this was just the ecu upgrade. No race fuel, no boost spike, etc....To me, the torque reading seems off on the Procede's dyno. Should have maintained through the rpm's instead of immediately dropping off????

There are many threads both here and on e90post.com regarding the PROcede results and many lengthy discussions. You should be able to find the answers you seek there.

I was not intending to put down your mod, just noting that your results seem to be very small increases and depending on the cost, you could have been better off with the PROcede or Eurobahn tuner. Both of those provide significantly more HP/TQ increases than your graphs indicate.

Also, the PROcede information posted by Shiv has always been on either 91 or 93 octane. No race fuel, no funny business. Read the threads and judge for yourself. A lot of work went into his tuning package and it has the bonus of being plug-and-play, installable/removable in 5 minutes, and completely undetectable to the dealership if you remove it prior to taking the car in for service.

Thanks for the info! I am going to look into it some more.....

You should also be aware that a reflash is generally thought to be detectable by the dealer and that if they detect it, they will void your warranty.

Should read -- your warranty will be voidable if the dealer deems the modification to be the cause of some problem that has occurred.

That said, it's not a good position to be in

Exactly why PROcede and Eurobahn Tuner products are a good idea. They are NOT a reflash or a ECU chip mod. They plug in and are easily removable. If your car goes in for service and the device is not installed there is no information in the ECU either that would indicate it was ever installed.

Well I have several people look at the dyno's and compare and after reviewing them I have to say I don't believe this is a small gain. I went back and spoke to ProtoTech and they said their program is designed for reliability as the motor is not that strong and they run 10 psi instead of the factory 8 psi, alot more power is available if they run more boost which we are assuming PROcede is doing. But what stands out the most is that the high torque number is only a spike and from that point on (according to the PROcede Vishnu Dyno) the horsepower and torque fall off steadily as the rpm's climb. If you look at the "after" dyno sheet on my car, you see that the torque curve remains across the whole power band, it does not fall away and the horsepower grows as the rpm's climb. This gives more actual power on the road. It would be loads of fun to run a PROcede car, I hear their is one running around here in Miami.
I think I said this already but I just wanted to clarify, my car has only a chip. No exhaust or any other mods and is running 93 octane Sunoco. By the way don't be fooled into thinking the dealer won't know every event that happens to your motor. Everything is logged in the factory "brain". I guess they can tell how many hours of operation, how many times it has been started, how much boost, and how many times you went over the limit, They know everything. From what I understand, my chip has been reformatted from within. All the limits have been modified so nothing will show up as a problem, all the check sums match. So unless the dealer dynos the car, they won't see any changes so I am not really worried about that. This was one of my major concerns. I have to say, I think it was well worth every penny!!!!!

You may want to do some more reading, there are numerous threads here and on e90post about the PROcede. The ECU does not record any events as a result of this mod. Shiv has been providing volumes of information while his product was being developed as well as answering any and all questions related to the results, etc.

Here are just a few:

I'm not here to tell you that you made a bad purchase or not to enjoy the results of your upgrade, just pointing out there are options which IMO yield much better results.

Werid you didnt gain too much.

It seems like i dynoed alot more than you stock. And im on 91 octane.

stock i dynoed 273 rwhp and 282 wtq.

With procede I dynoed 329 rwhp and 368 wtq. Thats 56 rwhp and 86 wtq gain at the wheels.

Should read -- your warranty will be voidable if the dealer deems the modification to be the cause of some problem that has occurred.

Good point. Me, 41 year old lawyer - voidable. Thread starter, likely not either - closer to void. (No offence)

a procede car would walk your car. get it on vid, i would like to see.

Just to go back to your original information for a minute, I don't think I expressed my confusion over your interpretations of the Dyno information very well.

I took my new ride and had it dynoed a few days after I received. Just like BMW said, it read 300hp and 300 ft. lbs. of torque.

Not sure where you see that (other than where it is written on top corner of the paper by hand). The Dyno runfile information clearly shows that your stock car had a max HP of 276 and a max TQ of 285.

Auto manufacturers publish HP at the crank, not the rear wheels, so even though BMW under-reported the HP of this car (it is most likely around 330HP at the crank) you are seeing the right numbers at the rear wheel for a stock car.

The results were 61.23 more horsepower and 71.26 more ft. lbs. of torque.

No. Again reading from the Dyno runfile information at the bottom, your chipped car has a max HP of 306 and a max TQ of 314. So your actual gains (without correcting for temperature, different dyno runs, etc) are 30 RWHP and 29 WTQ. Good, but not great.

This is why I suggest the other tuners that are available for the car. Even the Eurobahn tuner ($599) which is a more "conservative" tune compared to PROcede ($1300) gives better net wheel HP/TQ than this.

Eurotunerwerks is absolutely right, a PROcede car would WALK you easily.

I agree that you do have some nice gains and that your curve is nice and flat at about 300 lbft for most of the rev range. That's a nice improvement. Looking at the graphs for the proceed cars, they do peak then drop off so people saying that these cars have much higher gains than you car is a little misleading. That said, proceed cars seem to be holding well over 300lbft for the entire time that your car is steady at 300lbft so they are stronger, blus they are doing that on 91 oct. How much did you pay for the reflash?

Wow guys, open your eyes. This dude obviously has something to gain by posting this.

Don't really have anything to gain other than knowledge....... They remapped the factory parameters on the factory chip. I don't know, I thought flashing was something different. When I had it done, they told me this isn't a "flash", this isn't a "piggy back", etc.....

No offense but my first impression after reading the first post was this guy must be promoting this tuner shop in Florida or doesnt know what he's talking about. It was when he said "Just like BMW said, it read 300hp and 300 ft. lbs. of torque." I don't know of any stock e92 335i to be that high to the wheels.

But hey maybe he made a mistake so I'll give him the benefit of the doubt. However, its very clear to me that the PROcede yeilds MUCH better results. That being said, if he thinks and can prove his tunning is better than the PROcede, messured in results as in 0-60 and 1/4 mile times faster, then I stand corrected and I would love to hear about it.

One last thing...How much was it?

you cannot multiply by 18% to get crank values... bmw states that the driveline loss for the 335 is 15% for AT and 13% for MT.

Most 335's dyno stock at 270-280HP/TQ at the wheels, which is what yours did... which is way more than 300/300 bmw claims at the crank...

FYI...
Vishnu proCEDE does not require "cutting" wires, you just use a screwdriver to pop out the pins, it can be put back to stock in 10 minutes... no traces left behind

Flashing your ECU is worse because it cannot be reversed without leaving traces in the ECU

The procede gets 330-360HP and 360-390TQ AT THE WHEELS!...
