Note: We are able to source replacement E40’s but without a steady supply, our cost is market-based depending on what is available in the salvage yards. Please email firstname.lastname@example.org with your service number for up-to-date availability & market price.
If you are not sure if this is the correct module for your vehicle, please call before ordering! These E40 ECM modules are GM units. We will program your VIN and latest GM operating system onto it (included in cost). All connections/connectors are confirmed good before the part leaves our location. These modules do not include any performance tuning. If you would like to purchase tuning or a core with tuning please click HERE. If you would like us to delete VATS (security/anti-theft) we can do so for an additional $50. This will allow you to forgo a security relearn (and VATS often ends up failing anyway).
We do not require your core to be sent in as a core charge refund on this listing. These are purchased outright.
Please note: Any time you install another PCM into your vehicle that is not original to it, you will need to do a security relearn and a CASE relearn(whether it is from us, the dealership, or any other vendor). The security relearn can be done by yourself, it is a simple process. The CASE relearn (crank angle sensor error relearn) needs a Tech 2 scan tool or a higher end snap on scan tool to complete. Needing a CASE relearn will not keep the vehicle from driving, but should be done within two weeks of install if prompted by a check engine light for it. GTO’s require a special PIM relearn that needs to be done at the dealer.
