This has been discussed many times. The "chip" adds more fuel throughout th eRPM such that you don't have the bring the RPM's as high for the same effect. It's all dependent on your control of your right foot. Bu tif you baby it, your mileage definately will not be worse, the same to say the least.

has it done to your fuel economy?

What kind of MPG figures are you getting. Have you calculated the numbers?

The 0-60 times would OBVIOUSLY improve but who cares? Its the output power that we are concerning ourself with.

I think the 0-60 times are only around for those of us who cannot afford to have our cars dynoed.

Take a vid of this new chipped ride...I am curious to see.

A dyno sheet is excellent data...but, I'm inherently skeptical of promotional materials used by a biz to pitch a product. I'd prefer some independent "real world" confirmation of the performance gains. Again, I don't doubt these chips improve performance, I'd just like to see independent verifiable confirmation of those gains, e.g. pre/post 0-60 & 1/4 mile specs. I think gsxr has set the bar for independent assessments in the MB community, shy of full dyno run$.

Hmm my mistake. I thought the dyno sheet that was posted with the first post on the thread was an independent, not one that they just package along with the chip or whatever.

If that is the case, some independent data would be nice

I have just had my 99 chipped and also report a great increase in horsepower and torque. But one thing I noticed driving out of Oliver's was a slight resting the foot on the pedal miss/hesitation. Also when slowing down and then resting my foot on the pedal produces the same thing.

Has anyone else experienced this with the chip? Oliver said it will take some time to break in. The computer must learn he says. I have close to 300 miles and I still have the symptom.

0-60mph in 7.72 secs with the G-tech pro with no power braking does not have me complaining too much though.

Ok, call me crazy, but does anyone offer a high-economy engine chip? I love a fast diesel as much as the next person, but if I could get up to 40-45mpg with a small loss of power, I personally would be interested in that.

I've driven a stock 98 E300 before and it just flies compared to my 92 300D 2.5 Turbo. If I upgraded to a 98 or 99 and put in the high-economy chip, I'd still have a noticible power increase from my 93, thus I wouldn't be "missing" anything, so to speak.

Thoughts?

Sorry, but that's ghey.

invisik · #54 02-03-2006, 01:07 AM

Why do you say that? Don't have to be about power all the time, power is easy. Economy is more difficult.

aklim · #55 02-03-2006, 01:19 AM

Probably not. If you make it economical and 5 users buy it but you make power and 100 users buy it, where do you think they will stick their time and money into?

#56 02-03-2006, 02:37 AM

BTW I believe most of the fuel consuption (when the mpg figures are low) comes from acceleration...

...in making my 300SD more powerful by adding fuel, I have actaully INCREASED my mpg numbers for mixed driving. Around town they drop a little due to the extra accel fuel but if you are working a good mix, then the extra power actaully helps you get up to speed faster and take your foot out of it.

Some of the guys that have chipped their stuff might chime in here but I imagine they aren't seeing serious MPG losses....any increases?

I know its hard to drive the same way with more power....its like "hey now I can do 85 in this amount of time rather than 70...woo!" hehe

aklim · #57 02-03-2006, 03:42 AM

If I took it easy, I get maybe half to a mile more per gallon.

KERMA · #58 02-05-2006, 08:15 AM

You guys ever try RocketChip? http://www.Rocketchip.com
He does great work for the TDI's.

Don't know about MBs, because I don't think there's a chip available for my '91 300D.

But I can confidently report that my chipped TDI offers between 5 percent and 10 percent better fuel economy. With the Rocketchip II, which is designed for a larger nozzle mod that I haven't performed, my economy increased from 2 to 5 mpgs, or between 46 and 48 mpg in horrendous L.A. traffic.

Power increased by 25 hp and 50 ft. lbs. torque, which puts me at about 115 hp, slightly less than the 2.5T, but with far more grunt.

That said, I keep me foot out of it except for an occasional romp to exercise the turbo vanes or to zip through traffic. The ONLY downside has been a puff of smoke at WOT -- and a new clutch. My TDI has 110K, and I chipped it 10K ago, so I've run many tanks of fuel through her.

Yes My 1999 TDI Was chipped by Oliver at SpeedTuning with similar results.
With some additional Modifications I got as much as 53 MPG with no loss of power.
I would like to chip my 1999 E300TD as well. I have no doubt it will increase power but im looking for fuel ecomomy. I average 33-35 MPG with this vehicle.
