Our Frequently Asked Questions page covers questions that are frequently asked by our customers!

We don’t list a phone number on our Contact page as we prefer to do all of our business online.  This allows us to keep track of our messages, and makes it much less likely for us to make a mistake when completing your order.

Please use the Contact page or Facebook Messenger to drop us a message.  We do our best to respond to messages within a few hours.

As long as we have stock, orders made with immediate payment (i.e. not eCheque) and before 4PM AEST will generally be shipped inside two working days.

See the Shipping page for more info.

Our J3 Chips will work on any Ford EEC computers (yes, even overseas hardware). This includes EA, EB, EF, EL, XG, and XH Ford Falcons along with the N-series Fairlanes. For a list of the definitions and binaries we can offer tuning advice and support on, please see Tuning Files.

For EA-ED 6 Cylinder vehicles, we highly recommend fitting an EL ECU, for the reasons mentioned in Installing an EL ECU into EA-ED guide (this also explains how to keep the Trip Computer working where present). See the Library section for more info.

The answer to this depends on your what you want to do with your vehicle. If you are looking to get a standard tune to suit a manual conversion, or Disable Smartlock / Smartshield, a Stage 1 J3 Chip might be the best solution.  For those with mild modifications, like a camshaft, intake/exhaust changes, or if you are just looking to get the most out of your car, a Stage 2 J3 Chip is the best choice, while cars with turbo/supercharger installations would be after a Stage 3 J3 Chip. Finally, advanced users keen to DIY tune their cars should look at the J3 Chip and Programmer or Full House DIY Tuning Kit for all the gear required to tune yourself.

This is highly dependant on the vehicle and what the tune is like to begin with. Power can be made all over the curve – remember you spend the most time well below peak rpm!  Chasing power through the middle of the chart will make for a much more drivable and economical vehicle.  Using premium fuel adds additional benefit as the tune can be altered to suit the higher octane rating of premium fuel.  It is difficult or impossible to guess how much additional power will be made, however 5-10% increases are what we usually see.

Installation is a very simple process involving no special tools (some soldering may be required for AU Series 1 only). The J3 port on the ECU needs to be cleaned very well, then the chip simply plugs in! Read the J3 Chip Installation Instructions for more information and a step-by-step guide on how to install a J3 Chip.

Yes; we can supply a J3 Chip to suit your specifications. Supplying a dyno printout with RPM and AFR is highly recommended as it allows us to tailor the tune to your fuel curve. Ideally, we want to see AFR and RPM, and if possible at various throttle positions – i.e. WOT, 3/4, 1/2, 1/4.  There is a mode in Dyno Dynamics dyno software where it can do a readout in text showing the AFR at every 500rpm or so for the run.  If you can get that then great, else a chart or a couple of charts showing the above at a couple of throttle positions are a great start.

Just choose the right J3 Chip for your vehicle from the Product page and contact us with the specifications before ordering.

See our Library section for more information about DIY tuning. You will need some way of monitoring the AFR; preferably a Wideband O2 Kit like we sell on our DIY Products page, or a dyno. If this is a little out of your comfort zone, you can get a Stage 2 J3 Chip or Stage 3 J3 Chip or even see one of our Tuners to tune the car for you!

Yes. The Four Tune Selector Switch can be used to switch between the tunes. We normally recommend this for NOS, High/Low boost, High/Low octane, or Valet tunes. It is not necessary to use a switch for “Power vs Economy” tunes – we believe we can get good economy and power from a single tune, the only control being your right foot!

Yes, by anyone with one of our J3 Programmers. Just order a Custom Tune from the site, and email us with the details of what needs updating. For dyno tuning with one of our Tuners, contact the dealer directly for a price.

No. Unfortunately, the ECU can not modify the speedo signal. If you are handy with a soldering iron, you can look into a Jaycar Speedo Corrector kit, or see shiftkits.com.au for a ready made solution.

This depends on the model of ECU and the engine type. V8 ECUs use a MAF, so as long as you have enough resolution for the airflow, boost is not an issue. AU 6 cyl ECUs will need a XR6 Turbo MAP sensor to run any boost above 1psi. EA-EL 6 cyl ECUs can run boost with just a chip, but need a Fuel Cut Defeater to go beyond 10psi. We have seen an a few cars run over 350rwkw in this way with the right supporting fuel system.

Yes. We can remove Smartlock/Smartshield from all ECUs and PCMs, allowing simpler wiring when retrofitting engines to other vehicles. This allows the engine to be fitted with just the ECU and associated, loom; no key transponders or body module is required. We regularly do Smartlock/Smartshield Disable chips to suit Speedway cars, Hot Rods, 4x4s or even Boat engine conversions.
