Last week I visited the Upsolute Tuner shop in Charlotte NC; today I visited Renntech in Lake Park (West Palm Beach Florida)to check out their shop. Upsolute is offering a 14HP gain from stock 168HP to modified 182HP / 166 UP to 181 FT/LB torque FOR $500 instaled. Renntech is offering their Performance Package 1; 15HP gain from stock 168HP to modified 183 / 166 up to 183 FT/LB torque for $2,495. Question 1. is Upsolute for real? Question 2. Will my MB dealer be able to detect the modified chip? Question 3. Will a chip upgrade void my warrantee? Last question, should I go with Upsolute or Renntech?

 

i hope this helps some. i have an upsolute chip in my VW right now. i got it 3 months after i bought it brand new. everytime i took the car in for scheduled maintenance or warranty repair they have never said a thing or had the slightest worry. i had my instrument cluster replaced 3 times under warranty. the 2nd time was my fault when i took the cluster apart in order to get the rear fog light indicator to light up after i installed the rear fog and european light switch. whether it was my fault or not, the instrument clusters in the New Beetles had an awful reputation for the check engine light to come on, and stay on. instrument cluster 1 and 2 had the check engine light, the 3rd one the bell that chimes when your lights are on or key is in the ignition started to sound like it was dying, and it did, so they replaced the 3rd one. when upsolute installs the chip in your car, they remove the ECU. then they copy all the flash mem thats on the current ECU into the new Upsolute chip. then the new upsolute chip is soldered on the ECU. because all the original specs, VIN, engine type, etc, which were on the original chip are flashed onto the new Upsolute chip, the computer cant tell the difference when hooked up to car. there may some extreme testing that they could do to detect a chip, i dont know. all in all i would say you are pretty safe. if the chip is detected im sure it will void some part of the warranty, but chances are they wont know. i have friends w/ upsolute in TDI VW, Audi TT, BMW E46. they are all pleased as am i with mine. they also have a lot of info on their website www.upsolute.com

 

I recommend that you get a before and after dyno, and decide for yourself whether it is for real.

 

Renntech ONLY work on Mercedes and nothing else. Upsolute provide chips for many brands. Whether they can match what Renntech is doing, I have some hesitation. Dont get me wrong, I am not saying they're no good, its just I will be more comfortable to spend a little bit more and let a Mercedes ONLY tuner to modify my beloved MB. Just my $0.02!

 

But Renntech is almost 2grand more, so i would go for upsolute.

 

same here, i have a friend with an Upsolute chip in his E46 33Oci and i drove the car, and you can feel the difference! Amazing what that chip can do, go with Upsolute, 2 grand is too much for 15hp.

 

check the thread i made

 

It's only $370.00 installed according to their WEB site.

Has anyone done one of these on a C240?

 

It is $370 for all cars except Mercedes and Porsche. For Mercedes and Porsche it is $570. This is because the Mercedes and Porsche ECU's are much harder to work on according the Upsolute.

 

Well, I live in Charlotte, NC, and will probaly stop by the Upsolute tuner to check it out. I am still debating whether I want that chip or a radar detector for Christmas. If I do get the chip, I will let you guys know how it works.

 

How many of us would have happily checked an option box that said:

C8- 15HP boost over base motor-

It wouldn't have mattered how it was done, software or lower restriction exhaust, etc...we all would have happily done it. There are ricers out there paying 300 bucks for an intake that gives them 5HP at the top end, and 40 'sticker' HP when they hear it growl at full throttle.

If its a genuine 15HP, then its a steal.
