Someone said in one of the posts can't have Traction control with LPG. Why not?
What happens if you have dual fuel and flick the switch to go from petrol to LPG? That is assuming that TCL will work whilst running on petrol. There is so much good info, that's why I love these forums.

maybe its because you dont really NEED TCL when running duel fuel / lpg?! lol

aside from jokes ( i know lpg can be quite powerful when its tuned solely for LPG / correctly)

i cant think of a reason why TCL wouldnt be able to be used with lpg - where did u get this info from? i would be interested to read it :)

I vaguely remember something about a big explosion if the traction control turned on with LPG - but can't remember the mechanics behind it.

the only thing i could think of then, would be that as the engine has to work harder to get the same amount of output (vs petrol) and if trac control came slowing the wheels down.. it might cause backfire or worse maybe?

i spose that would be a valid reason.

what about the factory LPG maggys then - did they not get tcl?

How does the TCL work? does it cut the fuel supply? Maybe it's not possible or safe to cut LPG supply?

my understanding is traction control works with your ABS to stop the car sliding out around corners by applying brakes on either wheel at quick intervals. Don't think it has anything to do with fuel...?Could be wrong though im no expert...

I think stability control works by braking individual wheels to bring the car back into line.

I think traction control works by reducing power (reducing fuel delivery?) which results in less wheel spin.

But like lima i'm no expert so i could be wrong too lol

Traction control is only used under accelerating traction loss. (ABS is used under braking traction loss). Stability control is the one that concentrates on cornering traction loss, and is much more complicated.

AFAIK, most systems are incorporated with the ABS and throttle input. Some also utilise a form of ignition retard/cut, which i'm guessing that mitsubishi must use, hence why it is not usable. Cutting spark in and out on an LPG engine may potentially induce backfiring.

i thought i had to do with the air input (maybe a combination) because the versions with tcl have some extra equipment around the throttle body

(reducing fuel delivery?)

Or it could be as Mohit mentioned... it fuel cuts by reducing injector pulsewidth.. and seeing as how its on LPG, it cant do that with the mixer.

I have LPG (venturi type) and traction control on my TL VR magna. And yes, the traction control works correctly on both gas and petrol. And I know its working, it comes out to play every time the road is wet! :badgrin:

The fellas further up have pretty much covered it. Basically it depends how its implemented (Traction Control) from the manufacturer. If it cuts ignition there is potential for a backfire. If it works soley on ABS should be ok but i guess it depends how agressivley (spelling) it cuts in. The last thing you want is a manifold full of lpg if its a mixer or ring type to ignite makes a nice loud bang and breaks lots of plastics.

I was the one that mentioned T/C and LPG in a thread in the 380 section... Here is basically what i was going to post but i will link you instead.

http://en.wikipedia.org/wiki/Traction_control

Remember there are a few ways a T/C system can intervene depending on what type. But if you do have a manifold full of gas and the system decides that gaining traction would be best done with a spark cut then guess what will most likely happen when the spark cuts back in?

KABOOM!!!

When i have had the T/C system on the 380 kicking in hard you can hear a chuffing noise that sounds like a backfire of sorts. So my guess is that the T/C system on the 380 has decided that, 1 closing the throttle butterfly is doing sfa, 2 adding some brake to the front wheels is doing sfa and 3 maybe if i cut spark in combination with all these things i will gain some traction. But thats an educated guess. If someone wishes to correct me please do so. :)
