MHP

How many C63 owners would be interested in ECU only tuning from MHP? Cost would be $2250 and you would make the same power on the dyno as with our v2 tuning, but you wouldn't run as fast at the track due to the lack of a TCU tune.

Can you do just the TCU tune ? Honestly that's all I'm really interested in.

MHP

Yes, TCM tuning is now available by itself as well.

Thanks

Andy, An ECU tune alone was what I had first planned but I must say your TCU tweak has me rethinking. With what you have shown you can do with the 7-Spd TCU and ECU combined I think I would be disappointed or at least left wondering "what if" (I don't need that in my head) if I didn't go for both.

This will be my DD and occasional Road Track day (2 or 3 times a year) so I will need your help finding the middle ground.

This is going to be fun!!

Andy, what would be the cost on that?

MHP

Barry,
No question complete driveline tuning > either TCU or ECU alone. If you race the car at all, or just want the best possible tuning, it's a no brainer which route to go. IMO just getting rid of the short/inconsistant shifting was worth it to me, the vastly improved WOT shifting is icing on the cake and is literally priceless at the track.
As for your specific combo, every tune is custom so it won't be an issue.

Thanks
Andy

MHP

Same as ECU only, $2250 for C63s. $2500 for E/CLS 63s.


Thanks

Hey Andy..how much horsepower & torque are u gaining w/just the ECU tune?

MHP

Same as our ECU/TCU tune, as the TCU doesn't show on the dyno just on the road/track:

5th gear, SAE CF on a DJ fresh off the street with coolant/oil temps at 200F.

Andy, I know you 100% believe that ECU-only is not the way to go, but from a business standpoint I think you would have a real winner with this option. Given how hard it is to show the benefits of TCU tuning without a test drive (as we've discussed), I think you would miss out on a lot of potential customers by not giving them the option for ECU, TCU, or both.

Put my vote down as +1 to do this.

MHP

Doug,
Noted and done. ECU or TCU only are now available.

Thanks bud.

but the C is faster in S mode than M mode, i already have tested!

the S mode only do perfect changes! thats the reason...


i will have the 530hp aprox!?

MHP

Yes that is true, since the 7A is really a traditional automatic and the M shifting is so inconsistant stock. The shifting with TCM tuning is better in every mode by a longshot.

436rwhp/402rwtq 5th gear SAE

529hp/487tq with 17.5% DT Loss.

532hp/490tq with 18.0% DT Loss.

Thanks

Mr Chaz Tsai

definitely very interested in both the ECU and TCM tuning.
