so i installed mine this morning. and yes...the homelink settings stayed after disconnecting the battery (thanks!).
i know i'm running a genI rig, but i'll post my notes here since this is where the gb unichip action is at.
my install was decent & instructions were accurate! the ecu on genI is located behind the glove box, so most of my time was spent in that wonderful position of feet on ground, one a$$ cheek in the air and the other on the running board, while ribs were resting on the door sill and left elbow grinding into the floor mat right next to the bolt that holds the seat.
ANYWAYS.....i had some difficulty getting the pnp harness to stay put even after using the velcro, but all of the modular plugs "clicked" like they were supposed to. the unichip is mounted to the vent tube with one screw and the A/B switch is currently coiled up in the glove box.
i did not get a valid excuse to leave the house and try the unichip yet, but starting the engine was great. you could hear a little bit of a difference in that moment after you turn the key but before the engine actually comes on. there was more fuel in the air after this startup then before, but it's probably attributed to the truck learning it's new toy. i revved it up a few times and it looked like it was getting to 5000rpm with a lighter touch from my foot. i opened up the cutouts...no CEL (phew!) and revved some more.
she sounds very happy and i can not wait till i get her on the street.
oh yeah...i've only put in 89 octane since the day i brought her home. i intend to keep putting it in as well. i was thinking of dropping to 87 now that i have the chip, but hey...money grows on trees so i'll stick with 89. but since i have small trees i can't jump up to 91 octane!!!
