Thread: Positive Votes for 2.2 Puma's

Ok more to follow! but here is my new purchase! I managed to remember to take one picture in-between looking underneath it, and trying to get a idea of engine bay configuration and systems under the hood!

Does anybody have any technical knowledge of the TCS(Traction control system)? I'm going to wait until 30000km (Advice of the ARB mechanics, due to bedding in issues on all new trucks) before deciding to install front and rear diff locks.

I want to see how good the TCS is, I've had a good go at getting it stuck, especially on a good chassis twisting contour bank, but the system didn't seem quick enough to respond to the scenario?

Any technical explanation of the system would be great!

Has anybody bought a workshop manual for the 2.2 truck yet? I want to service it myself eventually! First service is scheduled at 20000km according to the book! I think I'll be halving that figure!

I will respond to this question as my first post on the ARLO forum,
I have TCS on my Suzuki Grand Vitara and it is fantastic off road, (too small though...will be buying a 110 Puma shortly)
So how does it work,
Basically to have wheel spin = no grip so what the TCS does is use the ABS ring segments and counts the rotational speed of the wheel, if one wheel is turning faster than the other wheel on the same axle it assumes that the wheel is spinning, then it sends a signal to the ABS modulator for that brake circuit and applies the brake enough to stop the wheel spin, thus all the power on the axle is transferred to the wheel that is not spinning ( which happens to have the most grip).
Also the engine timing gets retarded to reduce power to the spinning wheels (with the suzuki TCS)
Works great on firm surfaces....black soil mud is a issue where none of the wheels can get grip....you will find that the engine will rev up and down constantly, the trick here is to disconnect one of the ABS sensors so the TCS is Off...so you get full wheel spin....
I have owned a Diahatsu Feroza and a 2.8 Hilux, neither of them were able to to perform off road as good as my GV3 with TCS.

have a look at this Youtube link, it is a good example of TCS V'S locked diffs

TC takes a bit of getting used to. It's all about throttle control. When the vehicle gets crossed up and the TC hasn't kicked in (or isn't working hard enough) then try gently accelerating. This induces wheel spin which the on board computer detects and then responds to. TC will get you many places that you wouldn't get if you didn't have it, but it isn't as good a lockers. Vehicles with open diffs, TC and lockers all require different driving styles.

I bought a workshop manual from the AULRO shop on CD by mail order very good prompt service

Will the ARB diff lock's invalidate your warranty?

^^ x 2. Make sure you verify any warranty impact with your dealer and factor that into your decision.

Perhaps someone more qualified than me can comment, but if that were true then the concept of a factory installed diff lock wouldn't make sense. I know you can't get them on Defenders, but there are plenty of other cars that have them either as an option or as a standard feature.

I certainly need to find that out! I'll ring the dealer tomorrow, and see what happens!

Hi Dave

I've had Hector my fabulous 2.2 Puma ute for about a year now. Read any of my Aulro posts and you'll see I reckon the beast is awesome!

Hector's no urban run-around either, but consistently hauls heavy loads through mud and along some of the toughest property trails in the Territory, places where oriental competitors probably couldn't reach unladen!

Just done first service, all fine and no problems only rattling doors shortly after delivery which the Darwin dealers fixed under warranty in a couple of hours.

I have never once had the DPF light on or smelt burning so wouldn't know the DPF is there unless I hadn't read it. No turbo hose problems either. Build quality might not be quite as robust as earlier Land Rovers, but you get the best most reliable engine a working Land Rover has yet seen - surely that counts for something.

Just Luvin' my Land Rover
