1HD-FTE Performance chips

Check out UNICHIP, a bit more $$ but in my opinion the best, safety and performance wise.

Dan, there was a write-up in 4x4 Action comparing these chips. Rapid and Steinbauer were the top 2. The issues with the plug and play variety is that they provide extra power simply by dumping more fuel into your system. This can provide more power but at a cost, and the biggest is extra gas and temperatures. These types of things should be considered as part of a suite of mods, all complimenting each other. I'd not put on any chip without fitting a larger exhaust system with it. I'd also fit an EGT guage to let you know if and when your engine is heading into the death zone temperature wise.

I've added an integrated chip into my 79 (V8) ute and opted for the more expensive integrated model rather than a plug and play. This means that hours are spent on the dyno tuning it to your specific needs and also ensuring that it is fuelling appropriately to the vehicle thereby minimising the danger of blower her up.

I did a review in my ute build blog. It's towards the bottom of the page.


Ute Build - Performance Mods

Hi TroopyDan,
I purchased our HDJ79 ute in Oct 2004 and fitted the Diesel/Gas system 2 years later this has worked great (Gov subsidy was $2000 back in 2005) approx 20% Dynoed Power-Torque increase. I then fitted a 3" mandrel bent Exhaust System in 2007 which on the Dyno give about another 15% P/T increase with cooler exhaust temps (I have always fitted Boost/EGT gauges on 3 of my previous vehicles) as I have the current unit.
Also blanked off the EGR valve because even on these engines with the mix of diesel soot via EGR and oil mist from engine crankcase ventilation system cause excessive residue build up in the inlet manifold and under inlet valve heads. When this is done there is another advantage in that the cruise exhaust temps also drop approx 50 to 80 degrees.
After 9 years have decided to fit a Power Module matched with a Turbo Boost Map Sensor Voltage Clamp. This second item assists with tricking the factory computer to keep the fuel injection sequence operating when the Turbo Boost is increased above Std settings. I have adjusted mine to 18psi under full load with an in-line adjustable valve between the Turbo Wastegate and the Turbo Boost signal supply.
I have not had it on the Dyno yet but this last mod even on the lowest tune setting is giving what I have thought all along that the emission settings which they are brought into the country makes the engine lean on fuel up to the 1400rpm achieving a better low down pulling power and still no signs of excessive smoke/overfuelling.
My towing setup is close to 7T and I am finding it way better up the hills (using a gear higher than before) and from initial fuel figures is showing near identical usage so far, but this is early days. Exhaust temps are close to what they were before Chip fitment.
I have 9 years worth of fuel figures to compare with with future travelling. But my advice would be before fitting anything else I recommend that a 3" exhaust is the first mod to do. I have a friend who has worked in a popular exhaust company who has told me that most people have not bothered with Chip/Modules after fitment as they were happy with the increase in performance. The Module I purchased is a Diesel Smart System. I have always enjoyed getting the most out of my vehicles being an old rev head/motor mechanic.

Cheers Kev.
