Thread: Uni chip/ are they woth it...??

UniChip - Equipment Tests - Overlander 4WD Magazine - Australia's leading four wheel drive magazine. Interesting review , any other thoughts....Gary

A bit has changed since 2002.
Most dealers including Graeme Cooper have given up their Unichip franchise as Unichip charged them a monthly fee to use the software.

There is (or was 2 years ago) only one Unichip dealer in Sydney.

AFAIK Graeme Cooper now sell Haltech piggybacks which have the same functions.

I have had a Unichip since about 2002 and am very happy with it.

I have found GC were very conservative with the electronic advance curve, as they must be, and I have added about 3-4 degrees static without any pinging.

IMHO , a piggy back is a very good solution for "modernising" the 14CUX, as the Australian tune was always "rest of world" and set to AFAIR 89RON ., so there is always scope for much more advance.

You can get a replacement ECU probably for a similar cost, but this is without dyno time or fitting and you lose the research into starting strategies etc that the 14CUX has and cost carmakers millions in dyno time.

Back in about 2005 or so Graeme told me he hated fitting aftermarket ECUs even with dyno time as they were never as seamless as the 14CUX and there were always customer complaints.
I have experienced this with fellow club member cars , which never started as well as mine under say hot conditions.
So IMHO , the piggybacks are a good solution especially if you are not interested in doing your own R&D by driving in many different conditions while looking at a laptop, or do not have the time or the computer skills.
