I'm converting my '82 E350 w/400 (carburated non-catalyst open-loop) to run on propane (only, not dual-fuel).
I was looking for a closed-loop controller like the Dual Curve 5952 (see http://www.dualcurve.com/5952-frm23749.pdf).
but for a fraction of that cost, i picked up a new Dual Curve fuel controller 59681 and I'm wondering if this will work for me. It came without any instructions, but i have posted pix & details here: Dual Curve Fuel Controller III PN 59681 on Flickr - Photo Sharing!
As far as i can tell, the difference is that the 5952 has extra inputs including tachometer. Can anyone suggest if not having the RPM as input to the controller will be OK or a problem?
Thanx for any constructive input.

hm, upon further digging, the EEETEE unit that Raso's sells does not rely on RPM or TPS input, so it must be feasable: Eee Tee Digital Design Limited
let me rephrase the question then: What sort of processing/adjustment does the 5952 do with RPM and TPS input that the other processors are able to do without?
