HOW TO - Where is my ECU? Can I chip it for KLZE?
Where is my ECU?
-Goto the passenger footwell.
-Take off the plastic kick panel
-The ECU/PCM is located against the firewall as shown in blue in the image below:
How do I remove it?
-Unscrew the screws (4 or 5) attaching the mounts to the ECU and attached relay from both sides (passenger and driver side)
-Push in the yellow release tab of each plug. I used a large flathead screwdriver for this, but be careful, the plastic is quite soft.
-Pull out all plugs
What OBD do I have?
-OBDI has 3 usually yellow plugs
-OBDII has 4 usually grey plugs
-OBDII also has a diagnostic port around the center console
OBDI is the easiest for KLZE swaps, image below shows OBDI from a 1995 reg car:
Is my OBDI ECU chippable for KLZE
First take off the 4 phillips screws on top. Then there are like 4 or 5 more holding part of the ecu in. Take out those, and then flip up the board and look for the eprom with a sticker I circled it in red in the picture below. I need those numbers. the last 4 digits mainly. If it starts with a 16** it CANNOT be chipped. Example would be in the picture that one cannot be chipped. If it starts with like a 2*** it CAN be chipped.
Where can I get this chip?
