the answe to your question is that is allow wheel spin without decreasing power to the motor, it also disables ABS from kicking it. this helps because in our trucks we have an esp button, pushing it in 2wd or 4wd raises the tolerances of how much wheel spin is allowed before the engine power is kicked off and your system is stable. in 4wd low if you push and hold the button it increases the tolerance even more, it will display "ESP OFF" in the dash, but dont be fooled... if you have a lot of wheel spin it will still kick in. the benefit to this is if your doing something such as climbing a steep hill thats slippery, you wont lose power if your wheels slip and spin, thus helping you get over the obstacle. the negative effect is rode travel, if you drive without esp active on a road with a slippery surface the wheel spin may be undesired, and with no system correction there may be problems, mainly speaking, an accident. turning off esp is only intended for off road use... that and if you want ot do really cool donuts. just kidding.
Thank you this answered my question about 'ESP OFF' displayed when in 4wd Lo. This gets me thinking about a recent trip beach 4x4ing. I engaged 4x4 lo inorder to takle the beach dunes. I dont know whenther I was doing the right thing or not but I left 4xd lo engaled for 20mins or so and travelling approx 10-15km/h when my grearbox over heat mil light came on.
Would this MIL have been caused by the fact that esp was NOT completly off?
1 more question: Would 'ESP OFF' still be displayed when engaging switch of this mod?
