the one on the motor is supposed to improve torque, we have not had ours done also when you hit the throttle now its speeds up fast instead of real slow, maybe benk8680 can elaborate some more? one customer at our dealer had the motor done and said it was much better said it seemed like it had more torque and throttle was excellent.
i couldnt find anyone to tell me when it was released. u have to have the laptop to tell which software u have or change it . they were letting us give the motor another 100rpm(now its 50) which helps alot!
Our R66 had a update last August and it had ample power and torque but I was told there may be another update since then. I will ask my dealer to check it out as I have no way of telling which vers. I have. Thank you
The gta console will tell the console software only. Need to hook up a laptop to get engine software. I am sure we got the update over the winter. Also Agco doesn't want the rpm's raised with the new software.
