The Hummer was not ready and a couple other H1 owners came to town so I took the Disco to the Pismo Dunes today. Had a good time, but I did not enjoy all the issues the ABS and Traction Control system provided. Had a hard time going down really steep dunes with ABS constantly kicking in and the traction control sounds like a jackhammer running behind the dashboard. But, I was impressed with the speed I could get compared to the lumbering H1. I gotta say that the H1 will go on side slopes and approach and departure angles the Disco can not even dream of.

I enjoyed taking out the Disco, but it will probably be a daily driver more than an offroad rig, unless someone can tell me an easy way to disable the TTS and ABS. It will go more narrow places than the H1, so it will have some use.

 

Yes there is a way to turn the TC off, I believe that you need to lock the t-case in low and then turn the engine off, wait 5 sec and then restart the engine and it will be off until you put the t-case back in high.
Somebody will correct me if I am way off, check your owners manual, I think it says how in there.

 

that h1 is beautiful, with all the stuff it makes your land rover next to it look boring

anyone know how a defender would compare to the h1 in the dunes (approach angles etc.)

 

If that is the only way, it seems almost useless, as running around in low gear is not practical in the dunes.

 

do tc and abs have fuses? can you wire switches?

 

I give you props for having a REAL hummer.
I can see why your stock disco cant keep up. On the dunes at least.

 

Well according to RAVE the Defender has a max gradient of 45*, approach angle of 51*, departure angle of 35* and a wade depth of 20in and a ground clearance of 9in and a break over angle of 146*.

The DI has a max gradient of 45*, approach angle of 39*, departure angle of 29* wade depth of 20in ground clearance of 8.5in and because they have the same chassis and wheel base I would assume the same break over angle as the Defender.

I cannot find this info for the DII in RAVE.


* = degree's

 

Looks like a ton of fun

 

But its still a hummer....................................still rather the Disco anyday.

Having a CDL in the sand is a LOT more beneficial than just the TC.

 

You don't have to be in low, just locked. That will turn off the t/c. If you put lockers in your diffs, the t/c will help them lock (unless they areair lockers).
