Hello Members
Been wondering about the feasibility of putting a chip in my 100 series to give it a bit more grunt in towing a 2.5 ton van.---Have heard about two types, 1.DP chip, and 2.Steinbaur chip, (I suppose there's more is there?)-- Would appreciate any feedback or advice regarding whether it's worth the cost or not, and does it improve performance to any great extent. Cheers....Sapper D

There is many to chose from, I have purchased a few for different types of vehicles. I have found the best ones are the ones you don't need to adjust. I have a STI fitted to my 2010 hilux and with exhaust it has made a massive difference. To start with you should look at doing the exhaust first then see if you need one.

Hi Brad,

I am also interested in this, what do you mean by "doing the exhaust"?

Hi Tony

I increased the size of my exhaust from standard to a 3inch system, it was a bolt on system no need for any modifications, it made it a different vehicle. acceleration was the greatly improved and fuel consumption improved also.
I have only done a few modifications to my car and doing this was the best money spent.
regards
Brad

A Chip will definitely improve your performance, As far as fuel economy is concerned there are benefits (once you have more power you tend to use it ). I fitted a Steinbaur chip in 2011 in my 100 Series ,before fitting a chip you should modify the exhaust I have a 3"Mandrel bent system from Beaudesert Exhaust and tow a 2.8 ton Van.
It is well worth the cost .
The principal is better air flow in, more fuel and better exhaust flow out equals better performance.
I also would recommend for better air flow a K and N Air Filter and if you don't have one a Snorkel
Hope this helps.
Cheers Joe.

There is an article on pradopoint.com re exhaust sizes and how the gas flow works.

Makes interesting reading makes sense.

Hi Sapper
In my opinion UNICHIP are the best. Match that to a 3" exhaust, you will be very very pleased. (check out the UNICHIP website, it explains the safety features)

I added a Safari D-tronic chip (ARB did it) to my 120 series Prado diesel 2005 model soon after I bought the vehicle and it made a HUGE difference to power and torque. Beats me why Toyota wouldn't fit such a chip as standard equipment. Fuel economy averages about 12.7litres/100km which is about bog standard for that era.

I too have wondered why vehicle makers have not chipped from new.

I guess it's for longevity and reliability. That additional power has to come from somewhere and leave it's mark likewise.

And a new exhaust and chip will buy a lot of fuel. And allow me to run hard in the bush and on the highway with confidence.

The amount of time I need extra grunt noway justifies spending that sort of money.

Now if I was a mechanic/auto electrician and covering 50 000 a year perhaps I would c it differently.

Unichip made the D-tronic for safari to be sold by ARB.

I was told once that as fuel quality varies markedly between markets around the world, the manufacturers default to a chip which will work adequately in all markets, in effect de-tuning the engine for markets like ours.

"Unichip made the D-tronic for safari to be sold by ARB."
I wasnt aware of that, but the Dtronic was prone to simply "cease to function" and was discontinued by ARB along with any backup

From my investigations a chip ups the fuel delivery pressure, which in turn supplies more fuel for a given injection time.
I think a cpu remap is a better option, as they can taper the fuel delivery at full load.
What ever you do, install an exhaust gas temperature gauge and drive to that.
The manufacturers tune the cpu to perform reliably performing to quoted specs.
If the car is rated to tow 3.5ton, it has to be able to do that with an intake ambient temperature of 50C+ without melting a piston.
When you start upping the fueling, exhaust gas temps and cylinder temps can go through the roof.
When towing a 3.5 ton van up a constant incline, into a 30knot headwind on a 40deg day, the last the need is overfueling.

I dont believe there are any parameters for a manufacturer such as "must be able to tow max rating in 50 degrees", other than their automotive engineers are prepared to warrant it for the required period

Can't speak for others, my d-tronic has been on for 260000k's with no problems. at times they come up for sale on the LCOOL site and a snapped up. there is a waiting to buy list on this site. have a good read on the UNICHIP concerning what it does and the safety features it runs in conjunction with the OEM ECU and you will see why I think it is the best.
