RENNtech vs Evolve 335d Tune

So to put it bluntly just buy whatever the hell you like and enjoy it as i am here in SUNNY 85 degree weather in Puerto Rico!!!

Really! I just want to fully understand what I am getting for the buck before I do it.

It helps to have friends like you, Alex, that provide us with info and war stories about how your mods and tunes are performing.

By the way I too am suffering in 86 Deg F heat here in South Florida. Time for another cold one!

Bump. Just purchased a 335d and thinking RENNtech vs. Evolve myself.

Hi guys,

Unfortunately, living in Toronto, Canada makes it very difficult for me to do the Evolve/Renntech 335d tune as I have to send my ECU to them. I have found a local tuner near me who promises gains of 54 HP and 65 TQ with their stage 1 ECU tune. They are affiliated with "Mega Speed" in Europe. Here is the link:

http://www.mega-speed.de/kraftfahrze...3er-e9091.html

What do you guys think? Here is what the local performance company replied when I emailed them:


For BMW new diesel engine we *offer German company *software:

http://www.mega-speed.de/kraftfahrze...3er-e9091.html

where You can see the tune specification.

The software upgrade was designed and tested at their dyno to give
optimal performance and fuel efficiency - however we do test and log*the car before and after to make sure everything is tune properly. We
have BMW dealer level software to do all necessary adaptation of the
transmission ECU.

The price for tuning 335D is $699 *- You have to call us to schedule
the time.

We own the newest equipment to do the most of the ECU's *including
tuning protected ECU's (most likely Your car has tuning protected EDC
17 ECU)

Let me know if You have any questions,

Best Regards

Also, I plan on visiting them this Friday to ask them about the warranty on the tune and what they'd do if the dealer updates my ECU and wipes out their tune.

What other questions should I be asking them? You guys have way more experience than me so I'd really appreciate your input.

Thanks!

Get it all in writing.

I would also ask hiw long they have been in business. In addition I would want to know how many other 335d's they have tuned. If the answer is 1 or 0 personally I would walk and get yourself the jbd and wait until Dinan releases their tune. If they claim they have tuned numerous d's then ask for references. You will want to speak to at least a few ownwers that have been running their tune for an extended period of time. Try and find an "independent" dyno or two to support the tuners claims. A tuner produced dyno means NOTHING, since dynos can be manipulated.

Also inquire about what perameters are manipulated by the tune eg injection timing, turbo boost, etc.

Fly by night tuners are a dime a dozen and your engine costs thousands so do your due diligence.

Great advice. Thanks.

You mention that I should wait for the Dinan tune. Will that be done remotely?

If you have an authorized Dinan BMW dealer near you you can get the flash done at the dealership.

Since Dinan has cooperation from BMW I am not sure if their tune will allow your ecu to be flashed via the OBDII port in which case you do not need to remove the ecu, but I don't know that to be the case. In all likelihood like with the rest of their tunes it will require the software to be downloaded at the dealer or to remove the ecu. Difference here being, Dinan provides the warranty coverage on your car if the servicing dealer finds it.

If you are in Toronto you may want to check these guys out. They are a Renntech dealer and at one point it looks like they were a Dinan dealer too. At the very least it looks like you may have access to Renntech so no need to remove the ecu.

Wow dude. Great find and much appreciated. I'm on it!

Here's the reply I got:

Good Morning John,

We are a Renntech dealer and can get all their products, but for any ECU tuning, the ECU does need to be shipped to Renntech in Florida.

Engineered Automotive has developed software for that car in house and can tune it with our own software. *The price for our software is on par with Renntech however we do not need to ship the ECU anywhere, and we also include a pre and post dyno run.

We have seen gains of 65-80 hp at the wheels, which is a huge difference.

Let me know if there is anymore information you require, or anything else I can do.

Thanks

yeah man, appreciate the guidance and help

i got the parrot mki 9100 with justcarkits.uk full aux unika kit..

works like a dream.

now trying to decide on ecu remap option

anyone do 0-60 test on this... I actually have an X5 35d and want to extrapolate what I would get on the RENNtech. Axel, you seem to have 1/4 miled your car...and numbers for 0-60?

I had JBD, but understand Remaps are better for the car...but when I did have it...my X5 set to max did the following.
0-60 6.1 seconds
1/4 mile was 14.9 seconds

just so there are some numbers for this. It's been impossible to find numbers for RENNtech

@vicsx5d I do not hv the 1/4 mile trapspeed or 0-60 times,but I hv the 1/2 mile speed of 129.68 with no time clocked,check me out at www.sneakyclub.com January 2012 event,click on RESULTADOS(results)

thank you sir! I saw that on your 1/4 mile speeds, but was curious about what I could do daily with out getting too arrested, lol

AAlso in YouTube search for RENNtech X5d 1/4 runs and you will see our BEASTS in action

Amigo its a half mile run NOT a quarter mile

LOL, lo siento, i ment 1/2 mile run. and thanks for the pointers! Also, just tried "youtubing" RENNtech X5d 1/4 mile runs and got " no matches for those results. would LOVE to see our beast in action

There is an X5M my bad, but here is the llink: http://www.renntechmercedes.com/www/node/681 . Speak with Bob and then Lenny que es de Panama
