u dont have to technically chip it...u can do it for free by urself...im not sure if its good or not but i ran with a auto p28 on my d15b everything werks no CEL light for auto lock tq....its simple..
heres a pic

on the lower left side u will find a series of resistors...its outlined in white in the pic...the rectangle area...its label very tiny but all u have to do is cut P17....there should be a lil resistor on there...thats it....plug it in and see if it werks...it werked for me...took 1 sec and ur done....

Damn, I wish I found this out sooner, I sent mine in to be converted for $20.

Oh well, when I get it back I can at least confirm.

Why did you cut rp18? I got mine converted and rp18 wasn't cut. But when I start my car, I have to prime it for about 10 secs and give it gas for a few secs before it will idle. If I don't, the car will die.

removing rp17 and jumpering rp18 is the correct way to do it.
