Available for all of the Atlas inline engines: 2800/2900, 3500/3700 and 4200. Send the engine harness out of your engine to be swapped, and we'll convert it for use in your vehicle.  Each conversion is custom, but generally, we'll get the engine starting off or your existing key, and integrate all the gauges and fuctions that are feasible.  The lead time on harnesses is about 4 weeks.

 

Your PCM will be tuned for stand alone use.  A performance tune will also be applied.  Return shipping is included.
