Like it says Flip chip for a Lightning that i used for about 2 weeks. I believe all second gen Lightnings used this ECU, but i'm not certain. Has a dash mounted switch, just flip the switch and you will be running a second tune for N20, different pulley, race fuel, etc. http://www.johnnylightningperf.com/s...roducts_id=171
