Mthis C63 vs C63 updated OE-tune
 

Today was OE-tune day. Mthis c63 got a dyno tune which put out 465whp Sae. I got my updated tune from Jeremy. Stand up guy as always. I wanted to see how much Hagi would pull. We ran twice and it was a close run. I'm surprised to say the least. Now Hagi where is the gopro video?

i got my car dyno tuned BUT this is NOT the ecu that was dyno tuned,


this ecu on the run below is my daily driver, i also stoped and got gas before all this went down car had 3/4 tank of gas (jon dint get no gas and his also good 40lbs diet then me and he also has a freak of a car) tnx for watching and ENJOY

That's a close race??

Good run guys.

Not exactly close, but still good runs.

looks like almost 2 cars to me

Looks like if the video was longer it was getting more Idk

Mthis would've nailed you even more in that video (pretty obvious). To know that this was not even the ECU that he conducted the dyno tune, means that if he was using it he wouldve demolished you.

There is no way that a C63 with a tune only (especially the same tune) that can keep up with a LT header tuned C63 from a roll on race. :)

I need to correct you jin has a factory freak

Ok that explains it. It wasn't the dyno tune ecu. But keeping up 1car to 35-140 is still impressive.

The gopro can be deceiving. We went from me getting a half car head start. Ending my front bumper on his passenger side.

That was the second run. First run was closer. You do have to know his car has light weight mods too. I was expecting like 3+cars to 35-140.

Show us the complete video:)

The video that was posted was cut off early.

Race him from 100km/hr-250km/hr (60-150mph) and lets see how close you can keep up, NO CHANCE!

Don't forget that he was a half car in front of Mthis :rolf:

+1

that and you can see and hear cleary @ 0.05 seconds he launched before Mthis

+1

Keeping up?

He was pulling on you every gear

You got stretched

Not sure what you guys think 50HP should look like but he walked you pretty good. I believe thats what 50HP will look like. He caught you and past you in a pretty short period of time and was continuing to leave you. Ya'll be safe!

Exactly. 50HP wont pull light a freight train for 10 cars. Its all about momentum, who jumps and where the race starts in a roll race.

From what I can see, Jon had the momentum jumping slightly first and he was about 1/2 to 3/4 car ahead before the race started. 50 more HP was still able to overcome that and pull a full car to 1 1/2 cars overall. If this was the race file tune it would have been more like 80HP and he would have pulled away much quicker.

At about 140 is where these cars start to plain off anyhow so where you are at from that point will not be such a dramatic pull. If you both took it to 180 Mthis would have been about 2 cars ahead with his pump fuel tune in this race. At least 3-4 with an even start from a dig.

So mthis was NOT on his race map, likely had adaptation issues, and had more fuel in his car?

And in that video, when the cars went on the 3rd honk, Jon was already three-quarters of a car ahead before they even went. So that's like a 2 car loss in such a short distance.

@mthis - Why don't you C63 guys just run meth injection or E85? Then you guys can run that race map without paying $12 a gallon for MS109.

Here we go again lol

How does E85 or meth injection allow us to run a race map???

? both raise the effective octane of pump gas. With E85 you may need larger injectors if they're not up to the task, but no such issues with meth injection.

Ah I never knew that. Ill have to do some reading thnx

Actually I wanted to go higher. But he backed off. Maybe a rematch is in order. What I've noticed is going into my 5th gear there is no more dead spot as the old tune 2 years ago.
