  • GM/Chevy Basemap Eeprom

Custom GM/Chevy Basemap Eeprom on a Genuine SST 27SF512 Chip.

We will contact you asap after order to get info/specs on your vehicle/engine setup to aid in the creation of your chip.

NOTE: Basemaps are not meant to get your setup 100% functional and tuned. They are meant to get your setup RUNNING and functioning enough to get to a tuner to properly tune your vehicle. Unless you are just doing EGR/VATS delete, etc and there are no major changes to the engine. Otherwise, with engine changes there needs to be further in person tuning. Sometimes depending on changes, YES the basemaps work perfectly fine and there are no issues, but some things are more easily diagosed with the proper tools IN PERSON by a Tuner.

You will need an adapter for your ECM to use these flash chips

Adapter will depend on ECM model.

Adapters listed here:

If your ECM has the wide Memcal/Eprom like this:
 
You will need our GM1 Memory Adapter

if your ECM has an eprom soldered into the main board, like this:

You will need our GM2 Memory Adapter and either install it, or mail it in to us to have it installed.




if you want to read your current tune and have that modified, you would need this to read a stock memcal:
