In the past I have seen it claimed that the 4g69 runs on 2 cylinders at certain times, like when at a complete stop, parked or whenever it's idling. I don't remember what site I saw it on, or if it was reputable, but now I can't find it officially in writing anywhere. The site said that it runs on two cylinders in order to increase fuel economy. It sounds to me like it could happen, it would even be advantageous, but I just don't know. Does anyone know if this is true, or is someone just making this up?

 

I know they can do that because some GM motors you can switch from 8 cylinders to using 4 but i've never heard of anything like that for our engines.

 

its not true

 

Lies!!!!

 

MD(Modular Displacement), was used in JAPANESE Mitsu engines such as 4g92 Mivec and 6A12 Mivec, at least I remember those 2. Mirage Cyborg Asti and FTO

 

if it was true then the system sucks cause my car eats gas like crazy,lol

 

Yeah, its not true. In the last 2-3 years, we've poured over every document, article and scrap of information on the ralliart and I've never seen anything to indicated that it runs on 2 cylanders. That and I'd notice it after driving it for 50k miles.

 

you can make it run on three with the snap on modis, but it just runs rough, and its for diagnosis only... (yes i know this is a completely useless post)
