![]() ![]() These systems are offered by companies like AEM, Haltech, MoTeC, EcuMaster, Emtron, Link, Max圎CU, Bosch, Cosworth, McLaren and others. These systems are designed specifically to maximize performance, reliability, and data acquisition in competition environments and are used by racers at all tiers of motorsport from entry-level club racers up to Formula 1, NASCAR, Ind圜ar, etc. The next option, and by far the most powerful one, is the use of a standalone engine management system (EMS). ![]() This allows a competitor who might be more budget-conscious to leverage the existing factory engine management yet still have great functionality. An example of such software would be EcuTek and their RaceROM feature which includes such motorsports features as boost off the line, map switching, FlexFuel, launch control, flat foot shift, speed density, and per-gear boost control. The first option that comes to mind would be different software platform that still utilizes the factory ECU as the basis for engine management but adds certain competition features. ![]() While this implementation did not meaningfully impact emissions controls, Cobb has decided to err on the side of caution and remove this feature from their software. This is due to the manner in which FlexFuel sensors communicate with the OEM ECU, which previously was utilizing an emissions-related component. In short, if you own a road-going Subaru you will largely be unaffected, but there are some items which are sadly no longer being offered, the major one being FlexFuel. These packages are being rushed through CARB certification in order to obtain full and transparent legality. They are developing new "Stage" packages that retain OEM emissions components but permit modifications in other areas such as intercoolers, air intakes, muffler systems, and more. Cobb's "Green Speed" plan has aligned their company with the changing landscape of federal regulations in order to ensure that their products and software will be 50-state legal. Non-competition vehicles will still be able to utilize the Cobb AccessPort and AccessTuner software. This is due to the fact that many competition vehicles omit certain OEM functions and the removal of these functions is no longer permitted under Cobb's new directives. These vehicles will no longer be able to utilize the Cobb AccessPort and AccessTuner software on the factory engine management systems. Many Subaru competition vehicles were able to utilize factory engine management systems including the ECU, with the help of aftermarket software, to permit modifications related to competition such as drag racing, road racing, autocross, time attack, rallycross, and more. I encourage you to read the full update linked here. This change would be made across the entire landscape of supported vehicles including Subaru competition, off-road vehicles. On April 18th, 2022 Cobb Tuning issued a press release notifying their customers that their AccessTuner software and Cobb AccessPort platform would be undergoing significant changes in an attempt to get ahead of increased federal regulatory and compliance mandates. ![]()
