LS and LT swap PCM tuning and startup calibration

PCM Tuners provides LS/LT swap tuning services for engine conversions and standalone LS/LT engine installations. Engine swaps often require PCM configuration changes, VATS removal, sensor adjustments, and drivability calibration before the vehicle will run correctly. These services help get LS/LT-powered project vehicles running reliably.

LS/LT swap startup issues

Many LS/LT swaps will crank but not start due to VATS security lockout. If your swap engine will not start, the first step is often a GM VATS delete which removes the factory anti-theft requirement from the PCM.
