A Canadian buddy of mine is a upsolute dealer, and has informed me that the retune for the 325i/330i is almost complete, they are just awaiting shipment of the retune devices, which will take about a week or two.

I was quoted $550 CAD for this, and will be doing it as soon as it is available.

I am doing a baseline dyno this week, and will do a dyno after the chip.

I'd be really interested in your results. That price seems rather reasonable if thos gains are for real.

I'm interested in this too, especially if you can post the dydno graphs on here before and after the mod.

i would like to see the difference in MPG as well before and after. That is a good boost in performance, but with the current / future prices of Gas i wouldnt want to have this chip cost an arm and 2 legs!

Retunes are always better on gas, if your driving habits stay the same, as you have more power/torque so the motor does less work then it did before.

This is supposed to eliminate the speed limiter as well.

That's a pretty good gain. Now if the dyno can back it up, I'll definitely be interested.

I wish there would be a better bump in torque... Overall though, those figures look good

Hmmm a company I've never heard of comes up with a chip before dinan TMS, conforti.............................

AND they get a 15-20 hp gain?????????????
when none of the above companies have been able to get gains like that on OBD II cars (15 or so was gained by late 80's BMW's by chipping)

If none of the big guys could do it on the E46, I doubt some little guy can do it for the E90 with no ill effects

I for one call

dinan seems to always release their new products late.
those are flywheel hp, not at the wheel hp. 15-20 gain do seem kind of high compared to the e46, but i think AA gained that much hp from their chipped e46 m3.
but if its true, i might consider getting 1

Before you guys do the mod, you should probably read this post by Dinan. Although it might seem biased since it is post by one company that's trying to say their product is better, but the part where it indicates how most companies get their hp "increases", it becomes pretty apparent how a major company like Dinan can't get any gains from remapping while other can claim major increase.

http://dinancars.com/whitepapersFile.asp?ID=9

"...This is still substantially less than the peak road value of 27° (Figure 13 - blue line) that would occur during actual road conditions. I believe that this is how most "power chips" are made, essentially leaning the mixture and advancing the ignition timing back to normal values. This will result in a measured power increase, however this gain is not real because it is merely compensation for the dyno environment."

I think the main point they were trying to make is that, during dyno testing, it's very difficult to duplicate real life road condition, so the car is actually performing at less than ideal condition. Because of that fact, the computer retard timing (essentially reducing power) to compensate. Base on this, most manufacturer adjust the timing/mixture ...etc back to normal condition which results in a power gain from what the dyno is showing. Unfortunately, when you take it out on the road and the car is running normal environment, that power chip adjustment becomes obsolete.

"...we seem to be the only BMW tuner that has come to grips with the fact that there is simply no horsepower to be gained from engine management tuning alone..."

+++++++++++++++++++++++++++++++++++++++++++
I'm not sure that Guess is correct about chips always improving fuel economy while improving hp and torque. This one might but I'm a bit skeptical. Has anyone confirmed that the chip in question also removes or reprograms the speed limiter? Data will be appreciated.

You guys crack me up.

UPsolute is the largest chip retuner/provider in the world. Its a German Company, much bigger then Dinan, therefore it has the power to do a retune before dinan does.

Also, every chip will be better on fuel economy. Its basic physics. Anything that improved hp, will improve economy.

so it magically gets more hp and uses less gas. OK

HP is not free, and is a result of burning fuel and air.
I've had chips in cars before, it never gave increased fuel economy and is certainly not a mod to save gas. I must say if anything it will hurt gas mileage (if it works) because it'd be more fun to floor the car and you'd do it more (again if it works)

I have a hard time believing that upsolute is the largest anything anywhere. If they had any size or marketshare I would imagine maybe seeing an ad or hearing about them somewhere. I read all the big car mags (automobile, C&D, R&T, motortrend, roundel, autoweek) and have never heard of them in my life.

don't try and sell this as a mileage increaser, if it works (which I doubt) the best you can hope for is not to hurt fuel economy

I find it very very hard to believe that in these days of power wars that BMW would just leave 20 hp on the table

I think BMW detuned the 325i a little so that they could market the 330i with 40 more horse powers. It is a possibiility. Can a 3-stage intake manifold system or something like that off the top of memory produce 40 extra real horse powers? It sort of relates to what GM did when they put a detuned Corvette motor (smaller cam, restricted intake and exhaust) in the Camaro/Firebird F-bodys. Yes, it is apples and oranges, but for a modern technology 3 liter inline six, you should be expecting 225+ hp, 200+ lb-ft torque.

I don't know the basic physics, but BMW may reduce performance on certain models for marketing purpose. Why didn't they just give all E90s the 150 MPH limiter? However, they would have a difficult time marketing the sport package cost. Couldn't BMW sell their technology secrets (optimum fuel mappings=>10 hp) to aftermarket companies (Dinan) that would increase both horsepower and mileage? Like taking the virtual banana out of the tail pipe. And maybe this virtual banana came with all BMWs from the factory.

Ya I would like a physics lesson also... how does a power chip = better gas milage? Damn Canadians

SOME remapping might result in better gas milage because usually factory tunes the fuel map to run a little more rich, to prevent detonation (knock) in the motor. So the remapping lean out the air/fuel mixture ratio, thus creating more power, at the same time using less gas. But that is only PART of remapping most of these chips work on. If that's the only thing, I wouldn't be buying that chip. Therefore, chipping a car doesn't automatically equates into better gas milage. Especially on BMW's where the motor works on valvetronic, the mixture is distributed a lot more evenly then compare to a regular throttle body intake.

So again, my suggestion to everyone would be to read that info page by Dinan then make your own decision whether to buy it or not.

Sure. Its quite simple.

When your driving on the highway, with the cruise control on @ 70mph and a steady incline is approaching, your car presses ever so lightly on the throttle.

with 200 hp (for example) it has to press the throttle harder, and for a longer period of time, then with 220hp. because at the same throttle application (lets say 20% throttle application) you are producing more power with the same amount of fuel (throttle related to how much air/fuel goes into your engine)

Chips retune fuel/air maps, and usually lean out fuel map curves, therefore producing more hp, with better economy. For the sake of emissions, manufacturers must allow cars to run very rich so all the onboard emissions equipment (namely your cat) can run properly.


Trust me, I worked with a chip retuner on my old car, a Mazda 3, and I had a chip retune done on my previous car before that, a Jetta 1.8t

With both I experienced better gas mileage once a retune was complete.


Don't doubt something unless you try it.

Also, quote from UPSolutes's website:
Quote:
All programs features air fuel, andignition timing. All programs are tuned with factory like smoothness and driveability. An improvement in fuel economy can also be seen if normal driving style is kept the same.
