Quagmire Posted April 29, 2009 Share Posted April 29, 2009 Right so the situation is this- i know I am in the Rangie forum, but figured there were more v8/LPG gurus in here: -B-Reg ragtop 90 -3.5 v8 rebuilt last November - is a 9.35:1 SD1 recon block, running 10 bolt heads and standard 3.5efi cam. -Using a 2 pin module Lucas electronic dizzy. -P6 style round airbox -Running on SU's, LPG is an open loop kit from Tinley, running a Bigas M84 vapouriser feeding via y-piece to the tinley mixer plates on each carb. Plans for the future are to: -Fit EFI and megasquirt, i have all the parts necessary on the LR side of things (have a lot of old flapper stuff around). Need to get EDIS and the squirt when funds allow. This would then allow me to run much more efficiently when on petrol and avoid drying out carb syndrome, and am hoping to be able to use a different ignition map when on LPG. So, the question is this. Are the closed loop stepper-motor type power valves worth using? I was looking at the one on Tinley, as this comes with a lambda sensor and boss, which will be needed for the EFI later. I could then let this control the mixture when on LPG, with the megasquirt providing the ignition side of things. Closed loop thingy, second down on the page here: Tinley Thanks Quote Link to comment Share on other sites More sharing options...
