C43 Cabriolet with EC tune - 12.4 @ 110.5 mph

Car weighed approximately 4200lbs and on 19" rims, stock tires. First time at the track and my shifting wasn't perfect. Sure I can get this car lower. Going for V2 next week, going to track it once more this season.

No, they're the numbers of your AMR sedan.

you talking about the AMR sedans that can't break 12.2 on 18" rims? Lol. Do the math bozo. EC tuned sedan with a good driver would be 12 flat minimum.

Lets see your time slips

why does this have to be a **** on what company you choose for a tune?

great numbers for a heavy *** cab, sedan weighs ~400 pounds less?

So now we can make assumptions on a sedan vs cab.. my car would do 10.5 if I had a pot of noodles on the roof... you are slower than AMR.. feel free to show me a slip that shows different ..BTW.. I’ve personally seen an AMR c43 sedan break 12 at New England drag way..so if you like your Eurochump tune by all means believe it’s the best all you want

I agree with this. But if you notice, a thread doesn't go by without the AMR 3 stooges here chiming in on how it's the best thing since sliced bread. I personally think all tuners are offering a similar product.

thanks. Yah- it's about 4200 for a cab and 3800 for sedan. Exact numbers based on MB specs is 460lbs difference.

Assumptions? Cab weighs 460lbs more. On average, 100lbs = 0.1 in the quarter mile. Simple math - google it if you don't want to take my word.

I look at the times & speeds based on my more than 40 years of drag racing experience.The car with the et of 12.2 & 117 mph is puting down more HP than the car with an et of 12.4 &110 mph.Your statement of ea 100 lbs = 1 mph is correct.If you apply this factor to the car that weighs 460 lbs more you get a trap speed of 114.6 mph.So I think the car traping 117 is puting down about 25 more HP than the one trapping 110.

ET is based on many factors and is not a good indicator of HP.Gearing,tires,driver skill,staging depth all play a factor in getting a good ET. I am not advocating for anyones tune,just looking at trap speeds and relative weights and using proven drag racing logic to determine which car is getting the most HP.

Everything you're saying is correct, but the car that trapped 117 is a stage 2 AMR sedan. I'm a stage 1 EC tuned cabriolet. Thanks for verifying my claim - someone with some common sense finally.

i agree with what has been said above look at the pure facts. anyone can argue their tune is best. lets look at facts.

weight of vehicles, trap speed, 60' time, and 1/4 time. i am pretty sure the stock c43 sedan can trap 108-110 stock and 12.8 1/4.

this cab although much heavier only trapped 110. his 60' is descent which is why his time works out. but also lets round up instead of round down. this is NOT a 12.4, its a 12.498. essentially 12.5 for anyone who never took math class. last time i checked if we are going to truncate decimals, 5 and up you round up, and 4 and under you round down. this is a 12.5 how ever you slice it. for a cab, id be happy at a 12.5. with a better launch (lighter/better tires wheels etc) and an empty stomach, i could see him a little quicker. but to call 12.498 a 12.4 and running the same time as another member trapping 5 mph faster and a true 12.4 12.2 whatever, is laughable.



keep in mind i have yet to buy any tune and this is an unbiased opinion.



on the street there is really not much difference between any of these tuned cars so yall should just all get along. if people want to spend more because they believe its a superior product let them. thats why we are driving these over the focus rs right or a honda type r. the bickering on who has the biggest dick (best tune) is just getting old. every single thread about how fast my tuned car went turns into a pissing match. grow up. we all have the same car. we all are enthusiasts. enjoy what you buy and build others up not dick them down.

Great post, but lets compare apples to apples. The 117 is a stage 2 AMR sedan. Again, I'm stage 1. I know everyone wants to neglect this fact but I don't have catless downpipes - I only have a tune and my car weighs 460lbs more. Are you also going to argue this isn't a factor?

the downpipes "stage 2" for any tune has proven to be mainly for sound only. there have been a few cars from oe tuning amr, maybe ec? that have run 12.2s on stage 1.

the biggest factor in your score is the 60'. you seem to have a good launch. maybe the extra weight is helping you off the line for max traction. the weight shows in your trap speed as you are much lower than the other tuned sedans and coupes.

from your results, i would say you are a better driver than the others with a similar tune. your skill has made up for the weight increase. seat you in a tuned sedan (amr, ec, oe), i bet thier 12.2 start to decrease.


edit: we need to see 1.7-1.8 60' to show good times. you are a 1.89 so you are starting to enter that perfect launch area.

Driver is definitely a factor. But Stage 2 with catless downpipes should produce an extra 30WHP on these cars. There is no stage 1 AMR sedan trapping at 117.

Simply trying to make a point that AMR is not a faster tune.

If it's trapping 114-115mph in a sedan, it's equivalent at best to my 110.5mph in my EC tuned cabriolet.

The 117mph trap is a stage 2 - and yes stage 2 makes more power than stage 1.

I'm open to be proven wrong but if you can agree with the simple math - show me an AMR stage 1 trapping higher than 115mph in the quarter.

It's really enough with the fanboy-ism attitude from everyone over AMR. Great tune, but not better than OE or EC.

a few threads discussing quarters. its all just forum talk so its hard to say exactly. but it seems a few of them one guy even in a c400 was hitting 115-116 on a stage 1 tune. i did not see 117 yet. but they were still getting 12.2s. i think its very driver dependent.


keep in mind i am not saying one tune is better than another. i think they are all in same ball park and the driver/environment is the biggest factor on the times.

Truly the most impressive results yet ha!

I am down for a piggy back as long as it's proven. They are generally and typically associated with not working from the Audi community I am coming from, however.

Hey, thanks for putting in some effort on the reply.

First link is actually OE - and impressive.

Second link is AMR staged 2

Yah, I saw Mike at that track that night. He ran a 12.2 @ 112mph with a burger motorsports piggy back.

Is this all not enough proof to say that AMR is not the best tune? I feel like you're now helping prove my point.

as i said above, i do not currently have a tune so I have an unbiased opinion. i am coming from a w204 c250 so this c43 is much much faster and i am trying to enjoy it in stock form as long as i can. this also allows me to see what everyone else is doing with tunes so i can make an informed decision.

from what i can see, all the tunes are very similar in times. and once again is very driver and environment dependent. i personally want a ecu tune just to get my speed limiter removed (my car shipped with all season tires and is limited at 130mph).

i think the value needs to come from customer service as well. but either way, ill be lurking still.

i think we can confirm you are a good driver. thats for sure. and your tune is reputable.
