Here's the "POWER PACK" that many have been asking for. You get the Ultimate Basic ECM and the RRM Lightweight Pulley together for a price that can't be beat.

The Ultimate Basic is the identical Engine Control Module as the Pro. The only difference is that the Methanol/Water Control system is not included. This again is the same 250+ h.p. and Torque unit. We have deleted the 2nd motherboard in the case in an effort to make the ULTIMATE even more accessible to the community.

More and more dynos and data logged runs are being done all over the the world now. All of this data is supporting new and better results for our customers. It is very common to see results that show over 250 h.p.!!!! The best selling unit with new settings and procedures that make it even better than before and it is being regularly accepted and even purchased by JEEP Dealership all over North America.

Road Race Motorsports is proud to announce our latest lightweight pulley system for the 1.4L MultiAir engine. The RRM pulley system is machined for stock fitment, OEM diameter, maximized throttle response, improved mileage and performance. RRM is no stranger to lightweight aluminum pulley kits, and has been developing both lightweight and underdriven pulleys for over a decade. On larger engines, underdrive pulley systems work well, but it is more important to reduce the rotating mass at either end of a smaller displacement engine; such as the 1.4L MultiAir engine. For this reason, we keep the factory pulley diameter, and reduce the weight of the entire system. This allows us to keep the stock-like characteristics, without causing a loss of alternator charge, or weak AC blast of air. The amazing diamond finish and detail make it unlike any other product like it on the market.

Attention to detail, and triple machining allows for the lightest pulley system on the market, including underdrive pulley kits! Weighing in at 1.67 lb, this aircraft grade aluminum pulley is lightweight and robust in design. CNC machined crank fire gear, heat treated, and blue zinc plating for long lasting corrosion resistance.

After 6 months, over 10K miles of BETA testing, and several design changes, we are finally ready to offer this jewel to the public. In the 10+ years of developing pulleys just like these, we have managed to produce THOUSANDS of pulleys with HUNDREDS OF THOUSANDS of miles without failures. We expect to offer the same quality to the JEEP community.
