First position was weird to me too. I am used to having two key position but the second position starts the car. I've heard there may be a key on sequence. However, it did seem to read the car...

I'm helping out a guy who has a bigger air intake and is getting some codes posted. I'd love to learn more about tuning this for increased air flow but perhaps as pressing is that I can't write to...

When moving to more air I am finding we are getting some errors here and there like p222b.

I was thinking it is related to the aircharge conversion.

Seems to have a lot of effect on power on m177.

I've been trying to read a 2019 mercedes and when i click read it goes thru and says read complete (shows the vin), but no file is produced.

On tunedmerceds.com I wrote this up as one of my first mods. Coming from Range Rover I saw first hand how the drop can affect the performance of sensitive electronics which may not result in optimal...

My hptuners isn't really reading cars anymore. It fails on the retrieving of the flash file from the service, so it can't unlock the ecu.

Sometimes changing the device works, but if HPT...

Ok I got 627.84 hp internally calculated.

I have some videos of cla45 coding on my instagram.com/tunedmercedes

Thanks sir. Just did all my indicated torque tables. And then saw your comment. Seems like the oem boost limits are good and are sort of the answer to an earlier question. As in these limits seem...

Some M177 table differences from M278/157

ok EGT limits 12842 on M157 I would be pretty aggressive. These seem very low from factory. I am guessing due to hot V? I am adding 5 right now across the board.

I've seen like 3 professional tunes for this car by the big guys. Like well known tuners. I've even tuned a few with the m157 turbo. Working with Truman we ended up getting a lot more power than...

hey so there is a spark table for heating you may want to check out

Thank you sir

I agree with outlaw. I can give some examples of 550 vs 63 vs tuned

Do we have any insight to the different tuning between C63 C63S and some of the GT cars? I think there is a widespread power difference and I believe the turbo set up is very similar on those. May...

M177?

Hey guys switched over to m177 platform. I'm looking for a C63S stock tune if possible, also would be interested in some of the m178 stock tunes if anyone has those or can point me in the direction....

nice work!

Ecm 15905 15810 15811 14861 14862

Looking at the difference between 157 and 278 the pre-catalyst tables are very different.

Using 157 pre catalyst tables prevents CEL with downpipes or with high flow cats iirc.

Is this safe...

also look at decal torque for noise reason or something like that.

Reducing normalized torque will increase the actual torque, increasing will decrease the torque. You only have about 50 torques to be off from the actual or you will get p061a or b. but for example...

Torque Model: Normalized Torque, Optimum Torque Table and Torque to Load Discussion.

There is a lot to cover here including lowering normalized torque to increase power and associated effects...
