leonardo 175

#1 Post by wnderer » Mon Aug 24, 2020 3:15 pm

Hi Guys/Gals,
I'm currently replacing the front end of my LPG system on my range rover p38 4.6 to replace the Cogas system that was fitted due to no tech info, parts missing & running on both petrol & gas see my previous post, viewtopic.php?f=28&t=15920&p=118405&hilit=cogas#p118405.

I'm fitting a single point leonardo 175 with 2 AEB 160 emulators & a OMVL R90 reducer i got most of the work done but stumped for a few wiring connections as follows. where to to take the rpm feed or coil feed (2 coils) from also on the leonardo 175 there is only one connection for the oxygen sensor but I've got 2 on my one for each bank (V8) do i just connect one or do i connect both to the leonardo hope there is a lpg guru that has done this set up before

I'm a great fan of the Leo, having run them on 4 of the 5 LPG cars I've owned, but as I previously said, I wouldn't risk fitting one on a Thor. In saying that, both my current GEMS P38s run Leos with no problems just make sure the ignition system and plugs are kept in perfect order (I change my plugs every 10,000 miles). RPM pickup can be taken from any of the pulse feeds to the coils, so any wire except the live feed. Connect to just one lambda sensor. The fuel is all going in at a single point so all cylinders will get the same amount, so if one bank is correct, the other one will be. Don't follow the instructions and cut into the lambda sensor wire, simply Tee into it with the Purple wire and leave the Grey wire sleeved so it can't short against anything.
