I have read the discussions re Chips but ask the following question :
What is the difference chips / mapping.
My D4D has done 350000km and has to do another 3
50 000 because I cannot afford another, I am happy at 120 and get 10km per litre
Am I wasting my time looking at this issue

Mike personally I would recommend that you stay away from any chips if you are planning to drive for another few years.

The extra performance comes at a price

If you happy with something that works, don't try to fix it would be my advice

Well,

I can write a VERY long post on this topic but in short:

Unichip.

The ONLY chip that gets installed on YOUR vehicle and then the maps is setup on YOUR vehicle and YOUR vehicle is dyno tuned for it to perform flawless whilst all safety parameters are checked.

Other chips that just gets plugged in on the fuel rail or where ever can only alter certain parameters at a set % - basically it is just an expensive box full of resistors.

Mapping...mmmm...although the maps are written for a vehicle, eg 3.0 D4D, it is most likely not checked on a dyno for engine safety. AND the original programming can NEVER be recovered, ie. it is irreversible. Futher point is that I have it on very good authority that ToySA know hoe and where to check for software upgrades and will definitely look at it if you have a warrantee claim.

You must ran fast and far from the guy who promises huge power gains - irresponsible tuning(and power) WILL kill your engine!

Always ask about what guarantee your chipper/mapper offer. Get it and writing and ask yourself if they can replace your cars engine THIS week if they screw it up - ie. can they perform on their warrantee? Truth is, most mappers do it from the boot of their car and can not offer the above warrantee.

And to save R1000/2000 on a chip after spending R3/4/5/600 000 on a car just does not make sense! Go for the best system with the best warrantee available!

- I have no interrest in the Unichip brand, just a very happy customer with more that 600 000 Unichipped KM's under the belt!
'02 KZ 'Lux. Cooled. Chipped. Onca'd. Cherished!

If you are a diesel fan, raise your hand.
If you aren't raising your hand, raise your standards!

A 4x4 is merely a machine that enables you to get stuck further away from civilization.

Good morning Mikehill

To answer your question simply:

Chips - Every modern car has an engine chip, which is part of the ECU (electronic control unit), that monitors how much fuel and air goes into the engine as well as the exhaust gases that come out.

Mapping – The original chip on the ECU cannot be altered or customised to your needs. An aftermarket chip needs to be used and the programming of it is the mapping.

Any vehicle can handle approximately 30% more power from the factory spec. But that’s brand-new. By chipping you would put additional strain on an engine which already has 350000km on clock, shortening the lifespan of the engine.

I agree with “JAWS”, he may try to frighten us with his big teeth, LOL, but he has given good advice.
"Mike personally I would recommend that you stay away from any chips if you are planning to drive for another few years.

I suggest you use a good quality engine oil and service regularly. I personally prefer to change engine oil between 5000 to 8000 Km, that’s just me.
Manufactures give different specs. They don’t care of the longevity of your engine. They know you will either support them for new spares or a new vehicle.
Travel is not really about leaving our homes, but leaving our habits.
Adventure tends to magnify all human emotions.
It's only in adventure that some people succeed in knowing themselves - in finding themselves.

Perhaps if you want to get some more performance, install a free flow exhaust( A good one, do your research) and get a front mounted intercooler, this is by far the most reliable power, it would be allowing cooler intake temps and more flow out and would probably extend the lifespan of the motor, only downside is that I have noticed a slight lag compared with a friends 4d4.

beware of fitting free flow on D4d:

https://www.hilux4x4.co.za/views/viewto ... =3&t=42524

"
I have a short exhaust that is very free flowing, makes a fantastic sound and causes the turbo to spool up rapidly. This however causes increased wear on the turbo actuator ring. This ring sits inside the turbo body and controls the VNT vanes. The turbo stepper motor moves this ring about with a little lever. This lever is a close running fit in the actuator ring. With time and use this fit becomes either too loose or too tight due to carbon or wear. This leads to a delayed reaction in boost reduction and ultimately a P1251.
I had this exhaust fitted in May 2016 and did a 12000km trip through Botswana, Nam, Zim and back without issue. Its only in the last 5000km since the trip that the issues have started.

I hear you Dalkill, I however have done close on 20000km with my bakkie since Ive owned it and no issues yet. The exhaust runs along the original lines as the old one, the only difference is removal of cat and bigger bore.
