Hey guys,

I remember some talk at retro rides about earthing the renix to allow the car to run on unleaded, was gonna get down and do this during the week but cant seem to find any help on the matter, Does anyone have a guide or a link to one which i could follow??

Cheers Dan.

it should run on unleaded allready by that age in reality.

Yea i haven't had any problems with her but wanted something to do tomorrow so figured i might as well do it, cant do any harm might even make the car run better.

Dan

Your car should have that earth internally inside the Renix mate.

Your car will certainly run on unleaded, I guess the question you're asking is "does it run on super unleaded (98 RON) or regular unleaded (95 RON)". You definitely don't need any lead-replacement additives or anything, it's just that pre '87 model year 340s were originally designed to use 96 RON leaded petrol.

A different Renix may help though, check out this thread:

B14.4E = 412 (1987ish on) Retarded by 4 deg. to run on unleaded.

Whether it's a straight swap, or if you need to make any further adjustments, 'fraid I don't know.

Cheers for all your help guys, i got a day of on thursday so will have a butcher under the bonnet at the renix and am gonna tidy the car up a bit.

No, but early cars with too much advance will have issues running on 95. More octanes (thats almost grammatically correct) means you can have more advance. Advance without the octanes can lead to bad things. Dan, if you have an early renix, either run on super for moar powerz, or get a late renix

ok well i have a looksey on thursday and get back to yall then with my finding and hopefully some piccies of the car as im gonna go loose with a spray can and get rid of some crappy patches lol.

Dan get a close look at that Renix thread at the top of the forum. The info on what terminal to earth should be in there somewhere.

Hold on I'll see if I can find it.

Edit: its not there....hold on I have info somewhere

OK, the blurb says you have to "Earth the B-Terminal on the Renix, using part number 3209295, connecting the white terminal to a good earth"

That means that you have to connect the inner most terminal on the unused plug to a good earth. That will retard the ignition to enable you to run normal unleaded safely, but you will lose some power.

To retain your current power levels safely you can use Super Unleaded but of course that hurts your wallet.

Sweet, Cheers andy, ill have a look tomorrow should the weather be nice which knowing my luck it wont be

Cheers Dan.
