Computer chips for LC 100 4.7 v8

I am looking for more power without to much cost

The 4X4 Action magazine did a comprehensive test of fuel managemnt chips in their mag three issues back. While the majority were for diesel, they did test a petrol chip as well. You should be able to find the results on their website.

The Hat,

I have a Unichip on my 100, 4.7 V8, I purchased my 100 new in 2004, I had the dealer put my 100 on LPG prior to purchase. (LPG Mixer system).

As I was not getting the power I expected from the LPG, I was told of the "extra" power and torque that I would get but having a Unichip installed would be between 10 and 15%.

The truth is you get very little increase in power from a chip on the V8.
If you look at the chart in 4WD Action you can see that you will get maybe 1-3% improvement.. Although 6-8% is quite possible.

Last year I changed to injected LPG and as this uses its own computer linked to the 100 ECU.
I now have similar power (if not better) on LPG to what I get on petrol.
The bonus part was that I did get an increase in power on petrol as it was detuned for the old mixer LPG system.

I believe that since I have a decent mechanic servicing the 100 I have better performance that I had originally, so the chip seems irrelevant.

I don't have the torque figures unfortunately only kw. Figures are at the wheels.

I believe that the money is better spent on a 3" exhaust straight through system and extractors. Better flexibility and better breathing. I wish I had this done originally instead of the chip.

Please note that the company that installed my chip no longer exists so the telephone numbers are irrelevant.
