I did the ESS Stage 2 with no other engine mods and all I can say is .... hold on to your hat!!!!! The car breathes and flies now with seemingly almost unlimited power.

When I brought it to the dealer for a rear wiper problem and they reprogrammed the entire car (dumb-asses), ESS came back to my house (free of charge) to reprogram it! Now thats what I call service!

I would not go with GIAC. I have experience with their SW in a VW 1.8 GTI that ran lean and I switched to REVO with much better results. ESS is tried and true. No codes, no flags for the dealer, just pure, raw power.

BTW, my car seemed to be held back like the parking brake was set after receiving it back re-flashed from the dealer. I couldn't believe how slow it was. It felt like I was towing someone's house behind me.

The Burger Motorsports JB3 Processor currently holds the world record for the fastest 1 Series and 3 Series BMWs with the N54 engine. Given that you have the exact same engine, you can expect increases just north of 80 rear wheel horsepower and 80 ft/lbs torque on pump gas. With race gas, you can achieve a whole lot more.

In the real world, this translates to a much quicker car that's capable of embarrasing some other higher priced performance cars on the market.


When the BMS JB3 unit is removed (since it is a piggyback programmer) per their instructions, the unit is undetectable. There are no codes that are stored and the dealer would just assume that you've been on the stock tune off the stock ECU the entire time.

Dinan does back their product with a solid warranty. In the end, it depends on what the customer thinks is actually worth it. Many of our JB3 customers (including myself) follow the removal procedure before heading into the dealership. We've had fuel pumps replaced as well at the dealership even after running the JB3 programmer. So in the end, it's your choice.

And the world records prove it too.

Larger gains, less risk, and less money altogether.

Dimsport did a remote update; purportedly 357 hp, not sure of nm but it flies. Does 0-100 km/h (62 mph) in just under 6 secs compared to 6.8 secs before and top speed, now unlimited, should be somewhere between 280 and 292 km/h on the gps (174 to 181 mph); to be tested. This for a late 2007 535D wagon. Oh, and mileage at legal highway speeds went up from 14.4 km/l (44 mpg) to 17.5 km/l (41 mpg).

Um they are talking about the USA 535xi wagon... no 5 diesels here state side. The N54 is the Twin Turbo I6 that is being phased out for the N55 Dual scroll single turbo with Valvetronic DI.

The N54 535i sedans are already at or just under 0-60mph 6.0sec. the Xi sedans get a better jump but loose it in the 1/4 mile due to the weight, and that is stock... just imagine the 385/390 hp vs the "300" (really closer to 324...) The wagons should be close in times.

does active autoworks have a chip?

***make sure you search on e90posts before purchasing this, their AP2 is fairly new (early this year), and reviews/discussions are a good informative read over on e90posts. For the price of the AA chip you could go with a JB3 pin out or even a GIAC S1 flash...ESS S2 flash I believe is that price also..

I've been in a chipped Saloon. It was in the UK and done by DMS - one of the most respected (and expensive) over here.

I have to say it was awesome. I didn't have my 5 at the time, but it's what persuaded me to get one. Admittedly, I couldn't afford a 535d, and mine isn't chipped, but it's still a great car (when it works).

At the time, I had a 225hp Audi TT Coupe and it was easily faster than that off the line.

Thanks everyone.

I have 62k miles so I am out of warranty anyway. But, still considering either dinan or Vishnu. The 20% of special on dinan is helping a little. But, I still wonder, is it worth the extra price.

I plan to keep the car for about 3 years so I don't want to break anything too badly. Any remaining input?

go with a flash over a piggyback IMO, especially if you are worried about longevity IMO. Controls over timing, temp, and pressures just seem to be "safer" with flashes over piggybacks. Either way, you're going to get a good increase in performance, GL with you decision

Sorry, I know it is a bit old thread but there are unanswered posts.

So I can do ecu remap for N54 Egnine. to 380 hp and 394 torque with Octane 93/94 Guaranteed! for just $600 for tuned file (5series.net members only). PM me if you are interested.
You need Dimsport MyGenius device to download/upload the file from ECU using OBD2 port and it can store 2 files (Original and tuned). If you are interested for that device, I can get ones for you.
