Is it possible to convert the above without problems? EML from 02 sensors etc

Which systems, if any, are best suited to the 4.2 supercharged engine?

The 4.2 Supercharged runs port injection and can be converted, the later 5.0 runs direct injection.

I've converted a lot of vehicles with the Jag 4.2 supercharged engine, mostly Rangerover Supercharged. I've used AEB electronics on most of those but these days I'd use KME Nevo electronics. MJ injectors, Romano HD reducer, fuel return, electronic forced lube system, 8mm outlet tank valve.

I sell DIY kits but I wouldn't want to sell a DIY kit for this model of vehicle unless the DIYer already had a very good idea of what they were doing.

I'm currently putting right an LPG install on (yet another) Rangerover Supercharged that was fitted elsewhere.

Thanks for the reply with system details

It was due to go to a place used by me for installs and servicing on a different model Jaguar

Rang to confirm and they talked themselves out of it due to being unable to confirm the EML would not be affected

Most LPG converted supercharged Jag engine'd vehicles I see either have the EML on most of the time or the installer cheated (disabled the EML somehow, sometimes just a bulb out type cheat)! Those I convert don't have the EML on and I don't cheat, I just convert them properly ;-) Seems for most installers other model Jags are far simpler to get right, or at least not have the EML come on.
