Heres the new chip next to old one, NOTE, every chip has a “Moon” Cut into the side of the chip, when you install it, make sure the moon cut is still facing the same direction!!! (Shown)
The process of Desoldering is putting the gun where the pins are one by one, meanwhile pressing the suction, when the solder melts, you release the suction, and it sucks it all up. Pretty dang easy! NOTE: Try not to leave it on too long, it might damage the Oem Chip
A good note while desoldering, When it looks physically removed (the solder) then it most likely is, a good way to test this is hold the whole ecu board up to the light, if the solder is removed, you’ll see light shining through the pins.
I had a hell of a time taking the stock chip out, it was all desoldered so i thought, what next? I tried pulling it out, and pushing it out the solder pins, no so safe…What i had to do was shove something beneith the chip so it can pop up, i looked all over the place and nothing would fit under the chip (too close to circuit board) BUT, i found my sisters hair clip, which looked perfect for the job, its thin and has a grove on it, so the more u stick it in, the chip poped right off!!

Once chip is removed, its quite easy to solder, very easy actually. Solder the adapting chip onto it so u can switch programs.

Right when i started it up, my car didnt studder at all. It fired right up and rumbled, pretty much amazed me at first. Make sure u let ur ecu set itself, cuz when i first got in i was revving it testing it out, it caused the motor to idle very oddly, bouncing up and down. This worried me but then i reset the ecu again, the right way. and it idled fine, although pretty high (1200) but i adjusted the idle control screw and it idles perfect now. On the throttle, i felt a big difference throughout the whole band, you can actually hear the difference, it sounds a lot more crisp and has a lot more punch to it. The redline for the PYR is 8900, although i will never take it that far, its just FYI. Overall i feel this was a great mod for its price, any novice i woulda say could accomplish it, all u need is a steady hand.
