4 x 4 Australia - - Gear -

IF YOU’RE af­ter a se­ri­ous im­prove­ment in off-road abil­ity, you might be a lit­tle dis­ap­pointed. A trans­mis­sion remap is about get­ting the auto to work how it should from fac­tory. The prob­lem is, most au­tos are near-on per­fect al­ready at slowspeed work. The torque con­ver­tor slip­ping is a pos­i­tive thing that acts like re­duc­tion gears. As the torque con­ver­tor slips, you’re able to get the en­gine mak­ing peak torque while still keep­ing wheel speed low.

In some sit­u­a­tions, like steep de­scents, mo­men­tar­ily lock­ing the torque con­ver­tor can give you more en­gine brake; but the best off-road mod­i­fi­ca­tion for an auto slush-box is still a large ex­ter­nal cooler to keep tem­per­a­tures un­der con­trol.

That said, if you’re rack­ing up the kays do­ing se­ri­ous tour­ing or tow­ing, these mod­i­fi­ca­tions can save you huge amounts at the fuel bowser, and with lower run­ning tem­per­a­tures will make tow­ing in hot con­di­tions less of a con­cern. Both your wal­let and peace of mind will ben­e­fit.

Paul did of­fer a lit­tle cau­tion for peo­ple head­ing to their lo­cal Face­book tuner. “It’s very easy to stuff up,” he said. “There are count­less hours in fig­ur­ing out what does what, and get­ting it wrong can make the trans­mis­sion per­form worse than stock.”
