Notes: 

• The image is for illustrative purposes only.
• For flexibility, the assembly is not balanced so it can suit either Ecotec L36 or L67 Supercharged 3.8L engines with your own harmonic balancer and flywheel/flexplate. 
• The conrods come semi-finished so they can be honed and blueprinted to match your specific engine as well.
• Engine block will require machining to support the larger stroke crank.

Bump up the performance of your late model Commodore by installing an LS1 throttle body onto your V6 in order to substantially increase airflow.

Upgrading to a larger throttle body, allows supercharged V6 or Ecotec owners to port their elbow or inlet manifold respectively for even greater gains.

This product is also perfect for the utmost of modifications such as porting of the supercharger itself, which would not achieve anywhere near the maximum potential power of a ported elbow and LS1 throttle body combo.

Manufactured by a renowned engineering company you can be assured of the outstanding quality and workmanship of this product.

Made from the same heat blocking composite material as our thermal insulating manifold spacers, this adapter will eliminate heat soak from the intake manifold to your throttle body and intake ducting therefore keeping the entire intake system cooler.

Note: The LS1 throttle linkage isn't compatible with the Ecotec/L67 cable. To resolve this issue you can cut the LS1 throttle linkage off and weld on an Ecotec/L67 one.

Holden Commodore performance memcal to suit VS V6 engines including VS III manual/auto, also available is a throttle body memcal, specifically tuned to run with the MACE throttle body.

KEY BENEFITS

• 8kW to 12kW power gains! (even more when using 98-RON fuel)
• Fuel economy improvements
• Easy 10-minute DIY installation
• Guaranteed power gains, or your money back

WHY

Looking for the easiest improvement in horsepower, torque AND fuel economy on the market?

Fitting a performance MEMCAL to your VS V6 Commodore is easy and will provide measurable gains

in power and torque.Not only that, but your engine will make the power smoother, providing better acceleration.

You'€™ll even enjoy an improvement in fuel economy under normal driving conditions!

Sound too good to be true? Believe it.

WHAT

We work with a number of experienced engine tuners from around Australia to recalibrate the genuine Holden
MEMCALs that store your Commodore'€™s tune. This means that there'€™s no dodgy soldering or modification
to the physical unit, so you can be sure of what you're fitting to your pride and joy.

Each MEMCAL is recalibrated to suit your specific engine and gearbox type, as well as the model of Commodore you own.

Horsepower gains vary between different models and the condition of your particular engine. Our estimate is
a gain of about 8 to 12kW using standard 91-RON fuel, with an extra 2% using premium fuel.

Fuel economy gains will also vary between different models and the condition of your engine. Our conservative
estimate is an extra 40 to 50kms (V6) to the tank, but we would expect up to 100kms extra in some models.

The bottom line is that you WILL experience a fuel saving with our performance MEMCAL; even in a stock standard, unmodified Commodore.

HOW

Our performance MEMCALs feature recalibrated fuel and ignition parameters, meaning that your engine will be
more efficient; burning the fuel and air mixture cleaner, making more power. By adjusting these maps within
the tune of your Commodore'€™s MEMCAL, we fix the mass-production compromises Holden originally made, unlocking more power across the rev range and providing better fuel economy.

Our performance MEMCALs will also improve towing capabilities. Fitment is simple, handled by even the most
inexperienced DIY enthusiast in around 10-minutes with only basic tools.

Larger horsepower gains are possible when our performance MEMCALs are used in conjunction with a
free-flowing exhaust and a cold-air intake system. CLICK HERE to view our range of cold-air intakes for Commodores.
 

NOTES:

• We arent doing custom memcals
• Our performance MEMCALs are not suitable for forced induction applications, other than the factory supercharged L67 V6. If you have a highly modified engine or are running a custom supercharged or turbocharged setup, you require a custom one-off tune. If you are in doubt, please don't hesitate to contact us.

This memcal is for basic bolt on'€™s ONLY. This will not suit after market cams, Strokers, turbo's, custom superchargers or anything above 10PSI on a L67 Supercharged V6. You will require a custom dyno tune from a reputable workshop.We supply cam and chip packages separately as seen in the following links.ECOTEC COMP CAM & CHIP PACKAGE  - V8 5L CAM & CHIP PACKAGES  - VN VT CAM & CHIP PACKAGES €“ECOTEC CROW CAM & CHIP PACKAGE.

Make sure you clean your MAF sensor before installing your memcal. But cleaning your MAF sensor should be done on a regular basis to keep your cars performance at its best.

Since the release of the Holden Ecotec V6, we have built up an extensive library of tunes to accommodate a variety of builds and configurations with exceptional results. Each project that we receive is carefully analyzed based on the custom tune form, the customer is required to fill out after making the purchase. Once we have verified that the information provided complies with our tuning capabilities, a specific tune file is selected and slightly tweaked to tailor it to the vehicles current setup. This alleviates all the compromises that were made by Holden in the engine calibration during mass production.

We can cater for most modifications, ranging from a simple cold air intake all the way through to a camshaft upgrade or L67 conversion which will yield improvements such as; refined fuel economy, smoother power delivery, greater throttle response and of course an increase in all out power and torque.

If the vehicle is equipped with an automatic transmission, the settings are revamped to provide firmer gear shifts by increasing the line pressures which render the gearbox more reliable in the long term. Other features like adjusting the fan enable temps can also be made.

Power output will differ from model to model however, in a fair comparison we usually see at least an 8kw gain at the rear wheels in an absolutely stock vehicle, meaning the more modifications that have been made, the higher the final power figure will be.
Fitment is simple, handled by even the most inexperienced DIY enthusiast in around 10-minutes with only basic tools. The factory ECU is located behind the kick-panel of the passenger side foot-well. The battery should be disconnected during the entire switch-over procedure.

Vehicle Fitment Guide

Notes:

• Our performance PCMs are limited in what they can cater for. If you're running forced induction, nitrous, have built a stroker, heavily modified cylinder heads or a running a camshaft that we don't stock, a custom dyno tune is required instead. We can recommend a workshop if that's the case.
• These re-calibrations can also cater for L67 conversions and transmission swaps. However, if you have a VS/VT V6 Commodore or factory L67, your ECU will be able to take our cheaper re-calibrated memcal instead. Please contact us for any questions or concerns.
• Once you have purchased your performance tune, please download this form complete it as accurately as possible and email it back to info@maceengineering.com.au
• Make sure your MAF sensor is clean before installing your upgraded PCM.
• Buyer is responsible for the packaging of ECU/PCM and covering the postage cost. It is recommended to use Australia Post registered post service for insurance and traceability purposes.
• These performance recalibrations can take up to 5 business days to program after we have received your tune form.

Parts Guide

Please select the part number you require from the drop down menu by utilising our vehicle fitment guide and parts guide. 

Note: For an Ecotec V6 engine, L67 connecting rods will be required which can be purchased through another listing.

Brand new cranks are no longer sold by Holden.

The cost of a reground crank can be over $200 but most importantly, using a reground Ecotec crank in a high performance build is not the most reliable solution as they have been known to break.

It's for the reason we'€™ve gone to great lengths to source to source these brand new cranks.

Supply is limited, once they'™re gone they're gone for good.

Head bolts play a vital role in the sealing of the combustion chamber, oil/coolant channels and ambient air. Therefore, we recommend our Mahle cylinder head bolt set for the task. Having met and exceeded OEM specifications, these quality bolts are suited for standard and mildly modified applications. These are torque-to-yield (TTY) bolts which means they are designed to be tightened past their elastic limit, guaranteeing high and uniform clamping forces. Other benefits include pre-applied sealant to the threads eliminating the use of thread locker and no-retorquing is necessary after correct installation procedures have been followed.

This head bolt set suits Holden vehicles fitted with Ecotec L36 and L67 Supercharged V6 engines.

Contents:

• 16 X Head bolt

Vehicle Fitment Guide

Notes: 

• When torquing up bolts, an accurate torque wrench or angle gauge will be required to achieve correct clamping forces.
• Please follow the torque specifications as recommended by the service manual.
• TTY bolts are only to be used once due to permanent elongation and safety concerns.
