What ECU Suits Me

What is a Plug in Kit?

"Plug in" kit is a term used by Wolfems to describe an ECU kit that has been developed for direct replacement of your original ECU with minimal or no other modifications needed. This kit will allow you to tune the engine for more power to be gained . Plug in is just that !!! unplug your original ECU and plug this one in, allowing for full control over the engine and in most cases the transmission and dashboard. Most plug in kits that are made don’t just offer control of the standard functions of your engine, you will also be able to use the auxiliary input and out puts to control other functions that you wish to add to your vehicle. Such things like boost control and 2 step are standard fitment in most plug ins supplied by Wolf.

Why purchase a plug in over a wire in?

The other option is to buy a wire in and cut wires and “piggy back” the ecu with the original ECU, this can get very messy and if you are paying someone for the installation it can be costly for them to do this.

One of the benefits to having a plug in is that the vehicle stays in a relative standard form, so if down the track you wish to sell your vehicle you can remove the plug in and fit a standard ecu , then the ECU can be fitted into another vehicle.

You may also wish to drive to the Dyno shop and have them just tune the Wolf, you can drive down there on the standard ECU and back home on the Wolf with next to no effort.

Do I need a plug in or a wire in?

The choice is normally up to the customer to make on this question but a couple of points to keep in mind.

If you are building a project and you are thinking of fitting a wiring harness that suits the engine but did not come out in that car, we would always suggest you wire in the ecu, this way it looks neater everything fits your project and in 9 out 10 times will save you money.

If you have a project and the harness is standard to that vehicle then a plugin option is fine for you.

If you have a project and the harness is standard to the vehicle but has been cut up and repaired then a wire in option could be better for you.

Here are some guide lines to help you decide if you require a plug in or a wire in ecu.

Is the vehicles wiring standard?

  • Yes = plug in
  • No = 50/50 plug in/wire in

Is the vehicles wiring in good order or has it been hacked up and repaired?

  • Good = plug in
  • Bad = wire in

Has the vehicle had a loom fitted to the vehicle that does not belong to the vehicle eg: holden V8 loom fitted to a mini?

  • Yes = wire in
  • No = plug in

Are you chasing a problem with your existing ecu?

  • Yes = wire in
  • No = plug in

Do I have an ECU already ?

If you have an electronic fuel injected vehicle now then there is a good chance that you will have an ecu, ECU stands for Engine Control Unit.

So what power gains is a plug in going to give me?

This is always a hard one to answer as ever vehicle is different, we generally suggest that with out any mods being done to the vehicle you will see an 8% to 15% increase in power. Don’t forget that now you have full control over the engine so modifications such as more boost or different cams can now be added and more power gained.
