Import Performance Chip Tuning
RC offers tuning solutions for import cars with obd 1, and obd 2. Many mistakes are made tuning these cars by adding unnessary hardware to a closed loop vehicle and causing it to run in open loop. I see many aftermarket devices that actually hurt the oem tuning reducing fuel economy, and hurting overall performance.
Most import tunings are optimal and couldn't be made better, however, there is always the rev limiter and vmax limitations that frustrate folks. These cars also need to pass readiness "0" for emissions and therefore need fault tolerances opened up to allow for excess air/fuel/timing increases.
