PATROL 4.8 GRX Chip, map and freeflow
Posted: 27 Sep 2015 18:50
Hi Guys
Firstly just to congratulate everyone for a very informative and fantastic forum.
Thanks to the regulars for your warm welcome.
As mentioned on my Introduction..
I have spent many hours on here reading up as much as possible and it is nice to be able to identify with the South Africa feel to the various posts.
I am pleased to have joined what is really an exclusive club of Patrol owners and if nothing else I am sure we’re individuals who follow our own minds than subscribe to popular wisdom.
I guess that’s how we ended up as Patrol owners?
Speaking of which, there is so much one could find fault with the Patrol, especially the quality of Interior components but I personally am in love with my new Vehicle.
I found a 2008 4.8 GRX model with less than 65000 km, now on 67k, and while I probably paid way more than I should have, so far she has checked out fine.
I bought her impulsively on a Friday evening and it was raining hard, so her bodywork and other imperfections were well disguised.
I had looked at others and was disappointed and this one felt right.
Downside, the Patrol was black.
So I took the opportunity to do a complete colour change and am really happy with the result. Gun metal Grey.
One thing I really tried hard to find definitive answers to were performance enhancements. Having had a Super-Charged Colt before would have loved to have gone this route but just cant justify that spend anymore.
On the whole many seemed to say the 4.8 didn’t do well with being chipped.
Some having gone that route and then removing it.
I am a firm believer that you get what you pay for or at least enforce your right to get what you paid for.
So while there are many options as to whom to use I have always used Rob Green for a diverse variety of cars and while they are pricey I find them thorough.
I spoke to Graham, widely recommended on here and he certainly advised against chipping of the Patrol.
So my first post is really my opportunity to share my experience in this regard.
When I got my vehicle I found her a little lacklustre, but figured it’s a big heavy car.
I was also most interested in what real world fuel consumption would be.
My first drive to the farm was an economy drive, but on the 340 km distance there I can’t recall anyone passing me, so I was within general traffic flow parameters.
The car was completely standard and I did 15.5l/100 which I though was fantastic seeing everyone mentions 20.
Now having had her chipped with a free-flow exhaust, I kept the standard air-filter because of what I read on the forum, travelling a little quicker than before but still trying to do an economical trip I achieved 14.1/100.
Driving between 110 and 130, and up to 140 overtaking.
The attached maps will once and for all, I believe, prove the benefit of mapping a car by a competent tuner.
I then did the same 340 km trip again but this time a combination of steady pace and spirited drive, twice hitting the speed limiter at an indicated 200km/hr.
Fuel consumption 16.8l/100 km.
The thing is, my particular patrol would never have got to 200, I have not driven others, so no basis for comparison, but at 200, which is a true 190, there is still more available, so I will be having that limiter removed.
I see 200 km just as I am about to touch 4000 rpm so still way off the limit.
In fourth gear she now will pull cleanly all the way to 5000 rpm which is very close to 200.
I’m not sure that a Patrol will do this Standard and would be interested in experience of others.
I did tell Rob Green that I wasn’t interested in peak power, which is normally what a tuner sells you. You can’t drive these things at 5000 rpm.
I wanted torque, because that’s what provides your tractability and the exhaust designed for torque has turned my car into a completely different vehicle.
I would highly recommend it, it’s just better all-round.
With the extra power available, it has smoothed the cruise control noticeably.
However I feel the cruise control really only works properly at indicated speeds in excess of 130.
Crazy trying to cruise at 100 and having it change to third for a hill.
I can’t see how that’s going to be economical.
But set it at at least 130 and it’s a pleasure, the slightly higher revs mean it hardly even goes to 4th and in my experience never went to 3rd.
Having said that I doubt I will be using cruise control much at all.
