Diesel Power Chips

[bugman]

I have had my Defender chipped. It's not a generic chip it's designed specifically for the TD5 engine by Bruce Davis in Sydney.

I've done 80,000 km so far an a lot of that has been hard driving - towing big boats and hard off road stuff.

Best thing I have ever done - engine is as strong as ever and gives just as much performance as when I put it in.

Again mine was designed specifically for my engine and I haven't heard any real issues from anyone else with the same chip.

(actually it's a completely re-map ECU - but same sort of thing in overiding the original controls).

bendover, just wondering what diesel/gas system your mate is currently running and/or what system he would recommend. I have an 06 hilux (D4D) and have been thinking about this for a while, any info would be greatly appreciated.

[BenDover]

hey dunks84, all gas/diesel systems these days are very similar. Some just work better than others. He's running a D-Gas vapour injection system. He is actually running the black series, which is an older model and more simple than the newer ones which he has found works better than the newer models. He said he fits both systems for $2800 if anyone wants them. Oh yeah thats before the rebate (if you havnt already used it up) of $1750, so thats $1050 mates rates.

He's waiting on a new computer for his, otherwise he said he will take anyone for a spin and show them the difference.

Other info...
Exhaust temps stay the same as stock (not hotter)

Hi Dave.

I have had no experience with the chip you linked in this thread....I have however chipped my car.

I was in the market for a 4wd to tow the boat and do some offroading...after not finding anything that I was happy with on the second hand market....I looked at what was available brand new.....and I was dissapointed to say the least....I couldn't bring myself to fork over the dollars for a toyota, wether it be the 200 series or the 70....I had a look at Mitsi, Jeeps etc.....

In the end, I purchased the much maligned Nissan Patrol... The engines have had reliabilty issues, particularly the earlier models, and I knew there was an issue with power in the lower rev range..I knew this from driving them....a lot of the reliabilty issues have been addressed and at the price being offered, the car is great value for money IMO .......Cars not being my strong point, I did as much research as possible before making my decision and purchasing not only a car, but also the mods. The chip I ended up going for was a tunit chip - not to say its the best....just the one that addressed some of my concerns.

White pointer's comments about harmful emmissions are of concern.....and tunit claim to have scientifically proven that their chip reduces harmful emissions by a large amount, unlike other chips that increase harmful emissions.....whilst companies often make wild claims, I dont appear to have black smoke spewing from the car.....If I flat stick it, there is noticable exhaust, but this was no different prior to the mod.

For those that have said there is no noticable difference in perfomance after chippping and exhausting their 4bies....I would be askling:

1. Was the car on a dyno for an extended period of time and what were the results and

2. what were your expectatoins?

The reason why I wanted the mods was to address the slughisness down low...so that when I need the torque its there....wether it be because I am towing the boat up a hill etc. In my case, the mods did this and some. If the power down low is not an issue, I would not have bothered getting the mods as they arent cheap!


With regard to reliability of these mods, time will tell. The EGT of my vehicle is normal and boost is also normal. Also, all the factory fail safes are still intact.

The other thing that gets mentioned is that as soon as you chip a vehicle, you void the warranty of the car. Whilst some dealers will use this to avoid warranty claims, other dealers actually sell the chips themselves.

In this day and ages, why would anyone hand over $1500 for a $2 chip with some software that is mass writen fr conditions unknown. For similar money you can get a piggyback computer fitted and tuned on a dyno, just make sure it's has a plug in loom, so you can move it to another vehicle sometime in the future.

Hungry,

I went down that path to begin with but mine (landrover) doesn't have the plug in section and couldn't be piggy backed. Had to wait about another 18 months before the Landrover after market boys cracked the re-mapping of the ECU. Basically they install another ECU into yours. Take yours out and re-map it and put it in the next guys and so on and so on.

Cheers White Pointer, you raise some very good points. In the process of researching these mods for "MY" truck(themissus can't claim both) I've found several "chips" do no more than add extra fuel. The better versions will vary both fuel amount and timing and its not always adding more fuel either. Some will also increase boost pressure aswell. allup it depends on your engine and many of them respond differently to tuning than others. The jury is still out in my case as I am also interested in the DeiselGas systems. Mine isn't the Grenade ZD30 3.0l.....its just a little RD28ETi. They seem to respond well to fuel map and timing advance changes + freeflow exhaust. With regard to driveline....the only difference between mine and the larger TD4.2T is forward of the transfercase...everything else is the same so driveline is not an issue....gearbox is the same as fitted to 90's Nissan Skylines and 300ZX's including all the turbo versions....these were capable of holding onto 300hp engines with far superior torque than the RD28 even when multiplied through low ratio gearing. A workmate has just put a RB25T into his old RX3.0 GQ Patrol.....now that is an animal....and it's still bog standard from the skyline it came from.

Steve, I'd suggest you leave well enough alone with the Jack....they seem to be pretty pokey already, Maybe a better flowing exhaust would be all you need...seems most turbo deisels can benefit from this.

Timi, the boss had a DPchip fitted at Berrima deisel to his brand spanking 200 series....so far not really noticed a huge difference but they said he wouldn't really notice much untill he hooked up a van/boat and started towing....unfortunatly he sold the Barcrusher before getting the new cruiser so can't help you there. Berrima Deisel has a pretty solid reputation for quality work. I'd suggest you have a chat to them before making any decision.

Cheers, Roo.

G'day,

Ignore HP - it's the engine's lazy power. What's the engine torque? Multiply that number by the first gear ratio and then by the low range transfer case ratio. It is brutal. It has a brutal smashing effect clearing obstacles going from drive to over-run in low-low. Most 4x4 can't do this on a flat road for 15 minutes before something disintegrates. But this will need a relief team because after a few minutes of this you will be violently ill.

I remember a Land Rover 110 with a 3.9 Isuzu diesel I had. The governor was so tough that switching on the aircon on a steep descent with throttle off would momentarily lock the wheels. It had an overall low-low ratio of 44:1 available from 900rpm. The forces from wheels to tyre beads, to axles to drive shafts, to transfer case, to transmission to clutch to crankshaft were incredible.

I've also seen my share of exploded universal joints, twisted drive shafts, split transfer cases, stretched clutch mounting bolts and exploded clutch housing to know how to avoid it.

Drive gently and smoothly. Survey a route before you attack it. Feed in throttle gently so you just use enough to overcome obstacles. Hold one lower gear that you think you need and keep revs at the low range of the effective torque range. That will keep your speed down, your passengers comfortable and lower stress on you and your car.

Bugman,

Has your landy got the td5 motor? I have a discovery 11 with the td5 and have considered this option after speaking to my local Land Rover specialist in Mackay.

At present I don't tow anything too heavy so there's probably not any point yet, however the upgrade does have benfits such as shifting up a gear earlier (when cold) as it will not shift into top gear until it is operating temperature.

I have got a Steinbauer chip in my D40, yes id did make a difference and no fuel economy didn't go up. I am very happy with it.

G'day,

The problem for you with the 2.8 is that the transfer case feeds overrun torque to the Skyline transmission, which was designed for a passenger car, not for the torque multiplication of being bolted to a transfer case. First and second gears are where the shock of on-off throttle driving occurs clearing obstacles and picking a way through. This builds heat and can be very destructive to oils, seals and gear faces.

The 2.8 is a fine motor that has lumpy torque by virtue of being an early version of (then) emerging technologies. If the 2.8 had two turbos, one for off idle soft boost up to about 1500rpm and another for 1200rpm to (say) 4000rpm it would work much better than the lumpiness of the standard engine. It also might smooth out torque delivery so that if you drive gently it saves the rest of the driveline.
