Chipping an E320 4Matic
Hello, New member here. Just took over my wife's 2002 E320 4Matic wagon. I am impressed by how much more plush and comfortable it is than the GTI VR6 I was driving. My growing family means no more sports coupes for me.
One of the things I have been most disappointed with is the throttle response. There seems to be a notable lag between accelerator and acceleration. I assumed that a chip would be the solution. I was very close to pulling my ECU and sending it to one of the board sponsors for a Powerchip upgrade when my local mechanic, who is very squared away and knowledgable, expressed some cautionary words about the idea. His contention is that it is not the Engine Management Unit that is causing the sluggishness, but rather the 4matic drivetrain. He did not think that a chip would be the solution. But since he was not absolutely sure, he is more a mechanic/restorer of Benzes not a tuner, he thought I should get some real world info.
Does anyone have experience in tuning the ECU in a 4matic E320? I did some searching so as not to appear as a lazy, question posting newbie and while I could find references to the lag I could not find and information on this particular question.
I want to thank you all for the information I have already learned in my brief lurk here before I actually got the car. This is a cool community and I am hoping to be a long term contributing memeber.

Hey, i can not say much for a e320 but i have chipped a clk500 and a e300 turbodiesel the chip helps with the lag but is not the cure all. The power is slighltly increased as well as response. You can get a speedtuningusa chip for about $350, worth it in my opinion. You should also look into the sprint booster many have had great success with that. hope that helps

speedtuningusa
After running down all the options I am going to give Oliver and speedtuningusa a shot. I have read almost exclusively great things about him and his outfit and the price is certianly right 
I am just figuring out the timing for having my car out of service for the couple of days it takes to turn around the chip. I will post up results. Thanks for the interest. Bob

I have not noticed it reverting back to stock on my clk500. I can say for sure without a doubt it did not revert back on my e300 in the past 2 years. yes I'm still happy, since the e300 did not go back to stock i see no reason that any others would. TRUST ME if the diesel went back to stock i would know it instantly.

I also don't think there is much different between different comps doing ECU upgrade. Since it's software, one can decode and copy another's real quick. So I believe that speedtunning will not be off that far compare to Kleen or Ren.
I am also waiting on the dyno result from ashutt, another member here doing the chip. He will have his dyno on 4/21 and he promises to post the result soon. So far, he is happy with it.
I am going for it soon if the result proves some performance gain. Can't wait but will be a little bit bored and will miss my car when shipping out my ECU. My car will be in the garage for couple days

I am also awaiting the dyno results, can't wait to see them. My clk500 ran a 4.9 flat 0-60 after the chip using a escort fx2 accelerometer. Not sure how accurate it is but seems that it is very close if not accurate.

Aaron, I appricated speaking with you about Powerchips and when I made my choice price was the driving factor. I was very impressed with both your product and customer service. I do not think that the solution I have chosen infringes on your copyright. Thanks again and perhaps we can do some business in the future (if only you had that black grill in a flat gray )
)You're absolutely correct, your decision does not infringe on any copyrights and is well respected. The fact that developmental files were stolen from Powerchip and are being sold as other software does in fact warrant copyright infringement.
When it all boils down.. You can have a Rolex or a Folex, both will look fairly similar and work well initially, but you have no idea what's going to happen down the line. This is when a proven track record comes in.
Sorry for the rant, I just wanted to provide you with information I thought you should be aware of.
I wish you the best of luck in the future and feel free to contact me if you have any questions.
-Aaron
