4x4 Action Group

So at the moment there are 3 options out there:
1. Unichip
2. Other Chips
3. Remap

Which one would you choose and why?

Which one to select seems to be a very debatable topic.

Then you can through hardware into the mix as well -
performance exhaust,
bigger intercooler etc.

Why do we do it? Mostly for performance improvements. Why don't we look at it differently? How can we get safe power from an engine and even protect the engine?

This is what I set out to do. I have shared the process in the following video.

Remap.

I'd be VERY wary of a piggyback chip of any type.

Yes, indeed, al lot of them just add some gain to the output from the ECU. The Unichip links to the Canbus (basically the network of your vehicle).

Remap can also be dangerous if just a generic map is loaded and cannot be easily undone. It also has to be done on a Dyno (like with the Unichip).

Had a Unichip fitted by Steves Auto Clinic to my Pajero Sport long time ago. The Paj just cut out on long downhills, as in ignition off stuff. I got quite good at switch off and on again at 120kph!

Went back to SAC 3 times, no change. Eventually told them to remove it and give my bucks back.

My current Paj has been remapped, cat removed and egr blanked. Power up by 10%, torque up by 25%.

Very happy thank you.
