I got my Johnny Lightning chip installed about a week ago. Boy, what a difference... it's true what I read here, it makes the L into a totally different beast. My L is still almost stock... K&N and Amsoil is the only mods so far, so I was really curious as to the difference the chip would make. Before it was merely fast but now it's like the truck can hardly wait to take off fast and kick some butt! Install was very easy as well, except it is a pain scraping and sanding off that silicone covering.
But I have one question for you chip gurus out there... The Diablo chip I got from JL has a code of ABU213PD on it. I gather that ABU2 is the ECU code (got that from the door), but what does the 13PD mean? Is that the "program" flashed to the chip, and if so how can I decipher this?
Now I can hardly wait to get my new Accufab throttle body and JDM Silver Bullet Exhaust installed. TB is going on today, JDM is still on backorder

 

Jeff: I can't answer your code question but yes, a chip makes all the difference in the world to our Ls. I loved mine so much, I got three of them .

Is it a custom dyno tuned chip or over the counter chip? Do you have to have the chip reprogrammed after every mod?

Cool,

You'll like the JL chip, Really makes the L perform well..
