Thanks for the info. I think I would rather trade up to the c43 for the extra ponies rather than loose the piece of mind I have with the factory coverage.

Concur. You can disconnect the piggyback system but it still leaves traces. And I would not have a system that uses only one source, that being boost. Other piggyback models utilize 3-4 different sources to increase power, but none operate within the warranty and I doubt if any of these private companies will give a warranty on the engine.

The same dealership performance manager that told me he's hoping to be able to offer that Dinan tune soon told me that it wouldn't void warranty. It's reassuring to hear that from a dealer rep, but I'm not quite sure how that could be possible? It'd seem to me that changing mapping and boost settings would give Mercedes an out on warranty coverage should something happen with the engine. Is the dealer rep just blowing smoke up my ***? If I got something in writing from the dealer that it wouldn't affect my warranty (and part was purchased and installed by dealer) would that guarantee coverage or could Mercedes USA override the dealer?

Dinan offers a 4yr 50k consequential warranty on their products for BMW. It DOES not currently apply to the Dinantronic Sport unit (like I have on my car and others here do). I am guessing perhaps in the near future they may come out with other higher tier products with that same warranty and migrate it over to our cars, Audi etc. but that is purely speculation on my part?. maybe that is what your guy is referring to?

I received mine last week. Purchased from a member here on the forum. The difference is notable and the installation is maybe 5 minutes. I have to get my 10k service done Friday and Saturday i'm booked but i'm hoping to get an appointment with the nearest AWD dyno shop in 2-3 weeks to do some pulls. I'll be sure to post my numbers.

AutoTalent

This is correct. I am waiting on news for a higher tier unit. Will keep everyone updated.

I wrote Dinan but maybe someone here knows....

1) Does running in Sport+ or Race mode require racing gas or an ethanol blend?

2) Has Dinan published actual specs for the changes in boost/hp/tq between all the tuner modes?

subzero05

requires neither. I have 91 in my car and keep it in sport + mode and have had no issues. I have toggled back n forth to race as well and experienced no problems there either.

RemmyZero

Excellent. Thank you. I was holding off on using race mode out of that concern. I'll be checking it out for my ride home from work

So I went and got the car dyno'd today. First off I want to thank the guys at EFI Logics in Bethel, CT. Great guys out there, I highly recommend going to them for your dyno pulls if you're in need of an awd dyno in the nearby area.

So the attachment isn't the clearest scan but that shows the car in stock and in Sport+ mode on the dinan. The end result is the car dyno'd 194hp/239tq in stock mode. In Sport+ mode on the dinan it dyno'd at 204hp/256tq. In Race mode it only made maybe 1-2hp/2-3tq more than that. So overall a gain of 11hp/18tq.

Not bad for a 5 minute install but just not the advertised gain of 31lbs of torque. Now as I sit here writing this I am wondering if the guy put the car itself in Sport+ mode, or if that even matters. I failed to mention it so it's not their fault if it wasn't. In the end i'm still happy with it and will go back in the warmer weather to have them re-dyno it.

subzero05

thanks for the figures. Dyno's will vary a bit certainly and I have no idea if the car should've been in sport mode for the test, but I'm guessing it should be for the best pull(s).

AutoTalent

Bump! These are in stock

sterz85

Any news on the development for the C43?

subzero05

word is they are doing dyno work at Dinan right now on the 400/450 which should be the same as your car I would think?. maybe the guys at Auto Talent can inquire for ya!

removedCFGaccount

and, "endurance" testing....

I'm trying to gin up interest in a group buy!

sterz85

I'm definitely down for a group buy, they were pretty common on bimmerforums, but haven't seen many around here.

Group buy on the dinan tune and the awe exhaust. Buy one get one free

removedCFGaccount

That makes two....

CAN YOU POST THIS ON THE PRIVATE LOUNGE/AMG FORUM?

AutoTalent

Dinan thinks this should work and is asking me for a beta tester at a reduced price. Sending you PM

bluefang08

I would be in for a group buy.

removedCFGaccount

That's makes four....

AutoTalent

Just got in contact with Dinan and will see what I can do

removedCFGaccount

five have expressed an interest just today in the c400/450 chip!

AutoTalent

For anyone interested in a possible group buy please PM or email me directly at Golan@autotalent.com

I will message everyone as soon as I hear back!

removedCFGaccount

email sent!
