Thread: 255/70/16 vs 245/75/16 KM2's for a P38 - First post :)

I'm going for the 265/75's, thanks for the advice pbrown!

Like the sound of the ECU switch but if you pop a bag then you're gonna loose all the air anyway? With the emergency kit can't you just shut off the blown bag and fill the others with a compressor to give you a bit of support to get out of a situation?

If the ecu is awake it will send you to the bump stops regardless of how much air you feed in! Need to remove the delay timer if you want to pump it manually or shut the ecu off!

I managed to live without an eas fault when mine popped so after letting the compressors cool down a bit I could pump the other 3 bags up using the ecu and a jack on the offending corner to trick the system until I got to an obstacle when I had to shut the door properly. Which was not very long at all!

You lads on 32's are making me jealous btw!

It's not the size that matters its how you use it remember lol. But seriously these are the limit without more mods I feel. The front mud flaps had to be removed and now my car gets dirty ;-) And there are minor rubs which I find acceptable so They aren't perfect.

Yeh the point of the switch is to stop it before it let's all the air out. And water crossings so there is less risk of a fault in water.

Appreciate the comments pbrown, i'm going to take the gamble and try to find the find any scrub points as I go. Given I gain confidence in the mechanical soundness of the car I will to start suspension mods in the future.

Had a search on here about that switch? Couldn't find anything. Have you just put a bypass in the door or similar?

Pick up the car tomorrow!

I may not have read it in this forum. But the eas computer is under the passenger seat and there is a relay off memory which I put a switch inline to cut the Red and something striped wire that cuts the power. PM me if you have problems finding it when or if you put the switch in.

Pbrown, do you get any error messages ie sped limited to 55 kph come up on the dash when you turn the power off to the relay? I've used the purple with a red stripe wire that connects to the relay as the power to control with an external switch.
