Looking for feedback on performance chip for 335d

Hello,

I recently purchased a 335d and would like to install a performance chip made by Chip Express. http://www.chipexpress.com/ They appear to make a decent product for diesel engines... I am looking for feed back from anybody who is familiar with this company or could recommend a different solution.... thanks in advance for your feedback! I look forward to the results...lastly, i will post results once i select and install the product i ultimately purchase. - Cheers!

If you haven't, you might want to post this on e90post.com. More folks from outside the US who have experience upping the power on a diesel. I'd also make sure that the 335d chip they're offering is compatible with the US 335d. Not sure how much difference there is, other than the urea injection and power output in the US v. EU 335 but no one wants an expensive mistake, especially considering the complexity and cost of the fuel system on the 335d.

I spoke with Upsolute in Charlotte , N C about their reprogram and dyno for my 335d. The service advisor stated that they are getting over 300 hp and 500 ft lbs to the rear wheels all while improving fuel economy.. he wasnt sure but thought they could do it for about $500. I will also be looking closely at improving the air intake and exhaust .The 335d can match or better a M with these minor tweeks.

Maybe. In a straight line. But it's not going to handle nearly as well or sound as good. The M is a different animal. And no 6MT in diesel.

I can live with that as long as I can pull an M in a straight line while getting over double the economy. I guess there are trade offs for everything.

I call B.S. on those claims.

You may get over 300 hp, and close to 500 lb-ft of torque, but that will eventually rip the transmission apart. In addition, it will not IMPROVE fuel economy. Furthermore, hp/torque numbers alone don't "match or better" an M without gearing changes, etc... keep in mind how low a diesel engine revs...

there are plenty of chipped 335d in Europe with those kind of numbers, and the transmissions seem to hold up fine.

however, I'd be very doubtful that Upsolute would be willing to do anything with the N American version of the 335d.

Hmm. Forgot about the tranny. That is why we don't get the 6MT diesel. I guess the ZF automatic can handle 500 ft lbs?

Is this that gimmick with the resistor in a fancy box or does it actually change what the ECU does/thinks? (this is a real question, I'm not trying to flame)

the engine controls for any modern engine are pretty complex and work together very closely.

For example, the piezo-injectors on the 335d can fire several times in one second. boost needs to be controlled appropriately. There are sequential turbos that need to work together correctly. They also lift the speed limiter. This all requires a new program to be downloaded to the ECU.

Looks like the 335d ECU for US models hasn't yet been cracked: http://www.e90post.com/forums/showthread.php?t=283777...that is if you're looking to flash the ECU. The piggy back the OP suggested may still be an option, but the US ECU appears to be different than the EU version

I have a European model that was chipped. I love it... but I am looking forward to any update or anyone who does it... since a friend is looking for chipping his 335.

We're working on a PnP JB application for the 335D and X5D. But be warned, BMW has added some pretty sophisticated tuner protection to them. So make sure whatever product you go with has found a way to get around that should your car be under warranty.

It's amazing what a little more power/torque can do those. We were able to get the X5D 0-60 time down from an average of 7.1 stock to 6.4 tuned. Damn quick for such a heavy tank.

Mein Auto: VW Jetta TDI Chipped
Cool Chip will not "tear up" your tranny

I drive a 2000 VW Jetta TDI now (plan to get a used 335d when I return from Afghanistan in 2014) that I had chipped (Upsolute) in 2004 and with the larger installed Italian precision injectors can hold 100mph + without working very hard (the non M3 and 335d 3 series can't easily keep up for more than 20 or 30 miles without getting tired). It gets 37 mpg with the mods but only drops down to about 33mpg when I have my Cannondale on top and the AC blasting at full. As to the poster who said it will tear up the tranny, I would say that is simply not true. I replaced my original clutch at about 130k and there is definitely more pull but my tranny is fine. Perhaps his bad experience is due to a manufacturer's defect or missed tranny fluid interval changes or low quality fluid or all the above? I worked on Real Hummers in a combat zone in Iraq in 03-04 so I know a little about trannys and the effects of torque and heat. My dad's 98' Dodge with a Cummins lost the tranny at 105k but that was a common problem since the Cummins were huge in the torque dept. Smooth shifts and not jerking the clutch should avoid any tranny problems. Also, replacing the clutch when it needs it.

So, did it work? Sorry for the necro-post, I just picked up a used 09 335d and I love it and want to turn it into superbeast.

re programmed

just bought a 335d and have been impressed, how ever, I was talking to people about re programming mine, and I have had that done, it improvements are slamming, improved mpg, and the fact that I can smoke just about anything on the road, including the tuners and tweekers for the most part. my dyno, sheets show 364.7 hp and 509.3 ft torgue. being and avid street racer and drag racing fanatic I am greatly pleased.

whate tune did you have done? Or was it a box that got plugged in? Also, where the below numbers at the rear wheels or backed out to the crankshaft (appreciably higher)? Honestly, i've never heard hp for the 335d being up to ~360 hp. I've heard 306 to perhaps up to 316hp. Not doubting you in any way, just trying to characterize if this is rear wheel or at the crank numbers.
thanx, cuda
