Holden Performance Memcal

Plug-in style Memcal chip for Holden Commodore VN – VT models that replaces the factory unit in the vehicle’s Engine Control Unit (ECU). Enhances aftermarket modifications ie. exhaust, camshaft, other engine modifications and more.

The ChipTorque performance Memcal is provided with tuning modifications to deliver increases in acceleration by improving and correcting ignition and fuel curves to deliver the best torque no matter what modification your vehicle has installed. Upgrading the factory ECU, as opposed to the use of an aftermarket ECU, means that all of the nice “factory” driveability is retained, particularly on light throttle and highway cruise, to deliver the best all round result in performance and economy.

Specialising in tunes to suit engine modifications such as camshaft, head porting, manifold or fuel injector upgrades, ChipTorque can customise your vehicle’s program to recalibrate transmission gear shift points (VR-VT only), cooling fan control and rev limiters to achieve the best power and torque. For VR – VT we can set up an automatic ECU and wiring loom to work with a manual transmission conversion and remove the vehicle speed sensor if necessary. Additionally we can accommodate the changes required for engine conversions including removal of the vehicle anti-theft system to bypass the body control module.

Our Memcal is supplied on an exchange basis with a vehicle specific performance tune. For mail orders, please download our order form here, it has all the required fields we need to accurately process your order.

Your ECU / Memcal code can be found on the outside of the ECU case or on the Memcal itself, as shown below.

Performance Memcal Types

Our Performance Memcals are sorted into the following categories to suit different levels of modification.

HP0

Aftermarket tune to suit a standard vehicle to provide performance enhancements to suit higher octane fuel and improve on the factory tune. This product may not be beneficial in power gains for some vehicle models.

HP1

Aftermarket tune with corrections in fuel and timing to provide performance tune enhancements to suit a sports exhaust system with standard headers and higher octane fuel. This product may not be beneficial in power gains for some vehicle models.

HP2

Aftermarket tune with corrections in fuel and timing to provide performance tune enhancements to suit a sports exhaust system, aftermarket extractors and higher octane fuel. This is the base tune level provided for many vehicle models.  For L67 factory supercharged vehicle’s, this tune includes support for 10 Psi snout / pulley upgrades.

HP3

Aftermarket tune with corrections in fuel and timing to provide performance tune enhancements for aftermarket modifications at the level of a sports exhaust system, aftermarket extractors, mild camshaft 200-210 degrees duration @ 0.050″ or higher ratio roller rockers and higher octane fuel.  For L67 factory supercharged vehicle’s, this tune includes support for 10 Psi snout / pulley upgrades.

HP4

Aftermarket tune with corrections in fuel, timing and idle parameters to provide tune enhancements for performance and driveability for aftermarket modifications at the level of a sports exhaust system, extractors, camshaft with a duration around 210-218 @ 0.050″ and higher octane fuel.  For L67 factory supercharged vehicle’s, this tune includes support for 10 Psi snout / pulley upgrades.

HP5

Aftermarket tune with corrections in fuel, timing and idle parameters to provide tune enhancements for performance and driveability for aftermarket modifications at the level of a sports exhaust system, extractors, camshaft with a duration around 218-225 @ 0.050″ and higher octane fuel. It is highly recommended with this size camshaft to have higher compression than standard.

CUSTOM

Aftermarket custom tune with corrections in fuel, timing, idle parameters and rev limiters to provide tune enhancements for performance and drive-ability for aftermarket modifications at the level of a sports exhaust system, extractors, other camshafts up to approximately 242 degrees @ 0.050″ and higher octane fuel. Custom Memcals are also suitable for headwork, larger injectors, fuel systems, throttle bodies, manifolds, stroker kits and more. L67 factory supercharged vehicle’s with water to air intercooler and / or 12 Psi+ snout / pulley upgrades will normally require custom tuning.

Custom tunes produce the best result when dyno tuned, please contact ChipTorque to discuss if we can provide a mail order solution or start-up tune to suit your specific modifications. Custom Memcals may also be required for HP4 or lower performance modifications in an event where ChipTorque’s tuners need to make specific changes to the tune to suit engine or transmission conversions or allowing for modifications not listed in the above Memcal definitions. This also applies to turning off specific fault codes or ECU features as well as accommodating un-recommended modifications like an unnecessarily higher rev limit, excessively large injectors or L67 supercharged vehicles with air to air intercooler upgrades.

2BAR / MAFLESS

This memcal differs in hardware as well as tuning for most applications and features special coding within the tune to enable support using the factory ECU for forced induction enhancements like aftermarket supercharger or turbocharger upgrades. This product works with a 2 Bar MAP sensor upgrade to correctly tune for up to 2 Bar (14.5psi) of boost pressure. For MAP sensor based vehicles the standard 1 Bar MAP sensor is replaced, but for air flow meter based vehicles removal of the MAF sensor and wiring in either a 2 Bar or 3 Bar MAP sensor is required in conjunction with the MAFless Custom Memcal.

ChipTorque’s 2 Bar / MAFless Custom Memcal enhances the factory ECU to set it up to recognise positive boost pressure and our specialised programming ensures that the vehicle’s tuning responds in an optimal way by controlling the factory EFI sensors. As forced induction is a significant vehicle enhancement it is best to have your vehicle custom dyno tuned at ChipTorque for optimal results. Mail order supply is only available for MAP Sensor based vehicles.  Please contact ChipTorque to discuss supply of a mail order solution or startup tune to suit your specific modifications.

For air flow meter based vehicles (i.e V6 Ecotecs and VSIII-VT V8) the MAFless (2 or 3Bar) Custom Memcal is provided at ChipTorque Gold Coast only in conjunction with custom dyno tuning and can take 1 week to complete.

For vehicles with existing ChipTorque re-programmable Memcals, we offer upgrades to 2 Bar / MAFless Custom Memcal for a fee.

NO VATS

Commonly provided for VR onwards model engines used for engine conversions, where the complete engine, transmission, wiring loom and ECU are installed in another vehicle. This Memcal disables the Vehicle Anti Theft System to overcome no injector pulse / no start which will occur if the BCM, ignition barrel and key are not present in the conversion.
