Hi i'm looking to install a Performance Chip to my 78 series Troopy. Can any one recommend any? I.E pros and cons. I have been looking at the rapid chip and the Steinbauer. Rapid chip gets tuned to the car and the Steinbauer is a plug in unit. Is one better than the other? Personally i like the idea of the chip being tuned to my vehicle. what are your thoughts?

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

Completely agree. Unichip is head and shoulders above the rest but only as good as the person tuning it. Find a Unichip specialist and get it custom tuned to your vehicle.

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.

Hey Mick.
Thanks for the detailed reply.
The major problem i'm having is finding the right person to talk to. If you ring the chip company's, they tell you that you don't need an exhaust to gain power. They never mention the need to clear the heat from the motor or the extra strains caused by the chip. A bigger exhaust makes sense and so dose a the EGT and dyno tunning. Or i could just go slower and leave it stock.

Dan, do you have a reason for wanting the extra performance. In my case, I needed the extra power for towing and supporting the weight of the vehicle. My chip is tuned for towing so provides a wide, flat torque band. If you feel there's a demonstrated need for more power, well a chip is a great alternative but as I've said, unless you go for a fully integrated and tuned chip, there may well be some trade offs.

I always get annoyed with many of the sales people you see peddling their wares. They're interested in a sale so of course their pitch to you may gloss over the cautionary (dare I say potentially negative) aspects of the product they are selling. Nothing beats doing some research to inform yourself. With a chip, ask yourself these questions;

How does it work?
What does it do to the vehicles fuel management system?
How does it obtain the power increase (by what method)?
What are the safe guards against over fuelling & burning a hole in the top of the No.4 Piston?

If the gains are made through providing more fuel to the engine, well you can work out the next questions about increases in gases, temperature and pressures.

As an alternative, why don't you go with the fitment of a 3" exhaust first. There are potential power gains to be had there and it will support any later investment in a chip.

Food for thought.

Cheers and good luck with it.

G'day again Mick.
I was getting the chip because i'm heading off around OZ towing a near 3 ton caravan and a tinny strapped to the roof. My reasoning with, "maybe" getting the chip was, if i get better fuel acconomy whilst towing after 2 laps around oz the fuel saved would pay for the chip and as a bonus the van tows better with the increased power in the tug. The fact that the chip increases the fuel dumped into the motor also makes me question if there is any fuel savings to be made.
I am more than happy with the way the car goes how it is, so i'd more than likely be turning the chip off once we get to our destination.
After chatting with you i'm thinking that i might leave it for a while and just see how it goes. Like i said i don't really have a problem with going slow.
Thanks again for the reply.

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.
