Just returned from an 8000k trip from Vic to WA and back towing a camper trailer with my Hilux.

Before we left, I had a diesel chip installed after about 3 years of procrastinating. Will I or won't I? Is the $1600 just going to be worth it or will the change be minimal?" Will I notice the difference?

What an amazing change. Even the wife commented how much easier it was to tow. We have gained an extra gear. What used to be a second gear hill became and easy third gear, a third gear hill we could do in fourth gear and fourth gear hills we could coast over in fifth.

I found myself checking the rear view mirror a lot to make sure the camper was still with us.

Fuel economy I think is marginally better but will continue to check now that we are back. Compares favourably to a trip to Kangaroo Island four years ago allowing for a very windy return across the Nullarbor this time

Would recommend chipping a diesel for anyone who tows

If you tow in 5th you will halve your gearbox life. Its an overdrive ment for easy cruising. Mate has done two boxes in his troopy by 400000ks before he twigged.
I will use 5th if I can get away with small throttle openings. but only towing less then 1000kg in a v6 3.5 Jack.

Have a look at the huge long thread about " Towing in 5th gear on the C&M forum in the tech talk section.

It may well change your mind.

Cars have changed a lot in the last 30 years and just because your thinking hasnt doesnt make it right any more.

I would NEVER tow a van in 5th gear as according to my EGT gauge it runs hotter in 5th than 4th and doesnt use any more fuel.

Have you read thread 77363,

Quote
"The engine management system (computer)
of modern vehicles is an integral part of the
emission control system. Re-calibrating the engine
management system by changing the chip or reprogramming
or replacing the unit with an after
market computer, may result in non-compliance with
the emission control Australian Design Rule (ADR)
applicable to the vehicle."

Are you inciting people to break the law?

Interpret "May result" as OK your Honour. Insurance Company say it's ok as long as I am not 18.

Any (ANY) modification(s), unless approved to ADR standards, that change/alter/modify any aspect of your vehicle from the ADR standards/requirements that existed at the time of manufacture of your vehicle are ILLEGAL.

Nothing about MAY in the regulations.

Margo had one fitted to the Peugeot 307 HDI manual and it made a marked difference to it's performance. Before fitting it would need to be shifted back from 4th to 3rd round town making it a difficult car to drive in 60kph zones due to constant gear changing. After fitting it handles most 60kph situations in 4th very comfortably with no need to drop back to 3rd.


I had one fitted to the Rodeo and have no complaints at all about them.

I would happily recommend them to anyone with a turbo diesel.

On the last long trip ( Sunshine Coast to Canberra and return ) the Peugeot averaged 5.8 lt per 100km over a 2 week period both highway and round Canberra.

Like Mepvic I have read these threads about changing the chips. But unlike Mepvic I am still waiting for a report to say I get a would good return for the $1600 spent.

I think this will explain why. I did up a Kingswood back a while and could get anywhere between 8MPG (around Oran Park on a fun day) to 35MPG on a cruise up the coast on a Sunday just with my girlfriend. Before doing the work the best I got on the highway was 28MPG. I don't want the extra power I want the extra economy to get what I consider a "return on my investment". I do not mind dropping down a gear. A supercharger would do the same. But the fuel usage would hit the clouds for the same work done (you know what I mean).

I understand that the power would be helpful for loads and towing. But we are not towing nor do we have anything on the roof. We travel as light as possible. No restrictions then.

I want to know what kind of a "return for my money" I would get in economy. And in the bush not on the tar. Anyone???

You wont get any benefit economy wise from a chip.

Ive had a Safari in for 2 years and the economy hasnt changed one bit.

The pulling power has and it goes better but still uses the same amount of fuel.

You could say economy is perhaps better because you are sort of getting more bang for your buck. However when you fill up it still costs the same.

I thought so. Its really common sense then. Still doing the same amount of work in the same time just a different burn rate and gear etc etc.

But I thought I would ask anyway. The economy button is on the soles of our feet not in a chip hey!!!!

Thanks and happy easter.

hi
we have a hilux 2002 same motor as yours.
we also put a DP chip last year and we notice a difference when going up hill towing the van. (16').
fuel wise is not here nor there but not anymore than before, slightly on the lower though. by the way what is your fuel economy?
Enjoy and save trip around.

maybe you should fit a hyclone?
is an easy install and is only 10% of the price
if you don't think it works take it out and get your money back in full :-)

(as I duck the verbal diatribe )

Quite right Mainey

You can of course fit 5 in line and then with their claim of 20% less fuel you wont use any at all

My fuel usage is around 8.5K/L (12L/100K) normal around town. Pulling the trailer, around 6.5K/L (15.5L/100K). Dropped back to 5.5K/L (18.2L/100K) coming back across the Nullarbor against the wind.

I got a chip in my 2000 hilux, don't even have a turbo, made a huge difference just driving around. Worth it for me. I posted up the dyno chart here way back when I did it, the results for the KZ engine would have been way better.
