Nice gains.

What numbers are those..... can you please post up whp and tq.. also how much boost increase is there?

jamesyot

So what do we need in order to switch out maps and keep the car under warranty. Benz tuning is new to me. Is there a controller that goes along with this? Something similar to the Cobb Accessport?

benyl

How is it that the cla45 has been cracked for a handheld tune, but no handheld for the m157?

Awesome gains by the way.

ML63 AMG

Wow that was fast! Midrange gains look insane, 60-70hp/TQ gains in the midrange... that's a massive boost over stock (no pun intended) .

Can you find out the actual maximum difference in midrange gains and at what Rpm exactly? That would help out big time in showing just how much of a difference it makes where it counts (midrange).

Pretty amazing for only $999

elijah

Impressive & that was fast!!

zer0t

Yeah only about 14 hp difference. I'd have to look closer and see if there were more information, dyno sheet, etc. Renntech was founded by an ex-amg engineer and builds some wicked cars.

I'd also like to know if either will maintain warranty coverage.

InTheBenz0

Still waiting for a reply. You guys are US based, all other threads have WHP and WTQ and now im looking at NM and PS and non english graphs...

can you please post some before and after dynos... i want to see whp numbers and analyze the graphs.

Just confused at what you posted up... these are crank numbers...

benyl

I'm sure there are online converters your can use.

The tune was probably developed in Europe and as stated, euro charged is still waiting for their cla45.

radride

Exactly. Let me convert that for the lazy people:

HP went from 353.9 to 396 which is more than 14 last time I did grade 2 math

Torque went from 323 ft/lbs to 395 ft/lbs.

Those are substantial gains on this car but more importantly, look at the area under the curve.

R.K.

loungn14

your looking at around 40whp gain. We have seen some tuners over in europe pushing pretty hard with 60-70whp gains. We need more data before we do anything like that.

We are not going to release exact boost increases but will say its not as much as a lot out there by far. I know renntech is running 2 bar on one of their test cars. (max I believe)

it's more similar to jb3

ya no kidding, we are patiently waiting on that one as well!

biggest gains are around 5000-5500rpm



There isn't a tuner that will maintain factory coverage out there.

We are US based, but have eurocharged locations in London, UAE, south africa etc. We have been tuning the A45 for a bit now. Most non US tuners use NM and PS, we just happened to have a graph of a recent one to post as there are only a handful of cla45s in the US right now.

converting PS to HP is really close to 1:1 (technically 1 ps is .98 hp)

for NM to torque it's 1 newton meter = 0.737 pound foot tq

I will send a email out to our dealers and try and grab a us based graph

I can't wait to get this car, and rip into her. I know of quite a few of us wanting to do a full build on it!

I know a lot of people are saying the engine is maxed etc, but also remember people were saying the same thing about the M3's....and we know how that turned out!

It truly is an exiting platform!

InTheBenz0

Thank you for the further details in more detail. Once you guys get your cla45 the tune will evolve and you think there is more to be had?

loungn14

oh definitely....

We followed the same approach with the 63 platform. We originally posted a 40whp gain. We then got our own 63 and it didn't leave the dyno for a few weeks lol. After a few months of testing and many miles under her belt we released V3 and V4 of the tunes.

We are always trying to provide a better product as technology improves!

jonnyrt

its all the extra torque gained that concerns me for engine wear….~400 ft lbs of torque out of 2.0 litres! Thats a lot of torque for such small displacement!

TighTT

Audi, Subaru, and Mitsu guys have been doing it for decades. My A4 (1.8) puts out over 600wtq and just clicked over 195K miles. =)

nlpamg

Dafuq?! I assume your Audi 1.8 is fully built though, right?

I just want a tune safe for the stock engine. I don't want to have to change cams or pistons or sleeve it or anything.

ML63 AMG

So is the CLA45 motor... The entire motor is fully forged, and the transmission has carbon tip gears. The sucker is designed to be bulletproof.

Also, the CLA only peaks at 26.1 boost, then drops off so there is room to make power on the motors. 30psi is probably the safest that motor can handle. But there are other ways to make power than boost.

radride

That makes me laugh everytime someone says that about boost. 30psi on a 40mm turbo vs 30psi on a 80mm turbo is sooooooooooooooo different. I can boost the 80mm to 15psi and make more power than the 40mm at 30psi. So what you're saying is that the 80mm at 30psi will be fine and not hurt the motor?

R.K.

jamesyot

I think he was referring to the stock turbo bra

TighTT

Of course…fully built. As is the CLA.

Its not apples to apple, I understand. Im just saying I think there is room for more power, safely, in the CLA.

shahulhusman

I assume this will work for the GLA45 AMG also?

ML63 AMG

Correct, I am referring to stock motor bc 99% of cla45 owners will not touch turbo.

shahulhusman

yea, ill do a flash and brake pads/fluids and that will be it (of course with amg drivers pkg and the perf exhaust)
