Holden Memcal

Custom made to order

This is a complete replacement memcal for VN VP VR VS VT applications - made to order with basic changes to suit your requirements.

All Holdens up to VT had a memcal located behind a small cover on the ECU/PCM. It stores the operating system and calibration data. VX onwards did not have a memcal - that data was stored on flash storage built into the PCM.

Basic changes to the memcal can be made to suit your requirements, for example:

  • VATS off
  • Cooling fan temperature
  • Disable DTC's

I can also consolidate "piggy-back" type aftermarket memcals into a single replacement memcal - and delete VATS from them if desired. These are typically supplied with aftermarket camshafts, and require a standard memcal to be plugged in. For this you will need to mail me the aftermarket memcal expansion you have been supplied, I will read the file off it, write an exact copy to a replacement memcal (deleting VATS if you require), and send them both back to you. 

Please note: No tuning changes will be made. These memcals are supplied as standard calibrations, with basic changes only.

How do I order?

Please message me before purchase, and let me know the following details:

  • Engine / Transmission type
  • ECU / PCM service number
  • Memcal type (long or short)
  • Memcal BCC code (4 letters)
  • Required changes

The BCC code can be found on the memcal, written on the silver sticker attached to the chip under the blue cover. It can also be found on the white sticker on the outside of the ECU/PCM, assuming the ECU/PCM is the original one for the application and hasn't had the memcal changed already. There is 4 letters followed by 4 numbers - only the 4 letters are required.

Memcals are made to order. They are shipped 1 to 2 business days after purchase via Express post.
