Guys - the Cobb unit has not really been supported over the last 2 years, and between the support you can get for the JB4 and MHD (for flashing), I would do some more research.
I was going to go down this road myself, but there are better and cheaper solutions... |

OK, just my 2 cents concerning Cobb, MHD and JB4, without current in-depth research:
I bought my Cobb AP 3 two years ago. I believe the product is quite mature and failsafe with its original ECU backups and that there is not much left to improve within its scope as a map flasher and parameter monitor (OK, I would like to see an option for OBD readiness modifications). And there is still much space for own interventions with Access Tuner Race. So nothing to complain for me MHD is certainly a more modern and cost-effective option for new adopters, but I didn't keep track if it would really better suit my needs than Cobb AP. I simply do not need it. When I bought my Cobb AP, I also considered buying a JB4. But I did not like its approach to tamper with the car's sensor values and that there is additional hardware that needs to stay in the car - but this, of course, is only my opinion.

Another thing with sport and sport+ in manual is that you can easily get the car going with only the clutch, likely due to the throttle mapping. It makes going into 1st so much smoother.

Yeah, unfortunately. I've been in the "crapping pants while turning onto a major road from a side road with oncoming traffic" situation many times over the past four years. It's because the DCT is an automated manual, rather than an automatic (with lock-up torque converter) that goes the instant you tromp the gas pedal. I find that the Sport and Sport+ modes improve things a bit, but don't completely eliminate the issue. It's for this one reason alone that I want a manual back in whatever next car I get. Some will argue that a human-driven manual will have a similar delay off the line, but I think I'd feel better about it by feeling more in control of said delay.
Of course, once you're going, none can argue with the speed of the DCT upshifts.

Try driving a land rover for a week (or even better: a small slow reasonably priced car from the 90's so you feel genuinly unsafe) and get used to the space and time you need to turn onto a big road. That will fix most of your problems. Cause a fast car can make up for a lot of mistakes (and create quite some too...!), but squeezing yourself in front of a lorry when there is just not the space, is not one of them. Just my 2c. I drive in Normal and Sport btw. 50/50 |

But it is NOT the transmission
The delay is caused by the Dynamic Stability Control DSC. It is detecting the incipient wheelspin as you turn the wheel and get on the throttle. It is trying to stabilize the possible oversteer by both braking individual rear wheels and reducing throttle. So instead of spinning out in front of the lorry, the lorry rear-ends you. DCT allows some wheel spin so you have a shot at beating the lorry with less delay. DSC OFF allows you to depart quickly, with no interference but if it is wet you might do a 360 and have a head-on with the lorry.
My now classic 427 Corvette with 16" bias ply tires, and a cable to the three carburetors, was controlled by the drivers feet and hands and it always beat the lorry while leaving two black stripes on the pavement. Go figure. BTW in case you are wondering, the acceleration times of that ancient big block 4 speed Corvette were slightly slower than the 335 and the driver never felt much in the way of cornering Gs. The only ECU was between the drivers ears and it was very prone to failure but so satisfying when successful. So anyways, just pull out behind the damn lorry. |
