hi will the impco cdp-oz or commander fuel processor work with the impco l converter and 225 mixer thanks
Can't see how it will work as there is no fuel control with a mixer system, it's like a carby, put your foot down and in goes the fuel. Closed loop feedback from an O2 sensor won't make any difference to fuel delivery except with injection.
will the impco cdp-ox or commander ecu work with the impco l converter/225 mixer as theres impco cdp-oz or commander ecus on vr/vs v6 with the impco l converter and 225 mixer what works with the impco l converters and 225 mixers
the processor will work in conjunction with the 225 mixer and convertor when hooked up correctly , i dont have the diagram handy but once back at work should be able to find it for you and will post it up
can anyone that knows about auto electrics put a ecu in a existing gas system that starts a car on petrol then automatically switches to gas. will a ds101 dual start fuel control work on a impco lpg someone with a gas license said you only need a license to work on the liquid side
licenses are required to work on the high pressure side of the system correct , any other work can be performed by mechanics auto elec's , yet to here of anyone being busted for doing the work on the high pressure side without a license .
correct but would you ask a plumber to fix your electric lights at home ? better to have someone that knows how to fit it and set it up correctly
will it matter if anyone that knows about wiring harnesses and ecus works on the lpg electrical wiring and clear gauge
only matters if they stuff it up and short out wiring and ecu's induce voltage where its not meant to be , use of scotch locks instead of soldering connections bad earths and dodgy connections , seen lots of poorly converted cars over the years in the trade .
hi does anyone have a wiring diagram for the fcp-1 impco processor and will a impco cdp-oz work on a 225 mixer and e or l converter if a fcp-1 impco processor was there before where would you get a 2nd hand ds101 dual start fuel control and impco cdp-oz processor to
ok a bit of a dig. the impco 225 mixer setup i have recently installed uses a peel cp201 Fuel Processors basically it uses the o2 sensor feedback to control idle, opens, closes or pulses the air valve to control the gas flow (this controller can be set to open or closed loop mode, but it really works best if it is set to control the air valve and set idle screw correctly, otherwise you'll start throwing rich or lean error codes and be in lhm) now i haven't looked into it to much, but i know it controls the mixture at idle, it may also have some effect while cruising or opening the throttle quickly but i can't say for certain as the detail sheet about the controller is very vague about how it works...... as far as i've seen over the years, starting on petrol is controlled by the fuel/lpg switch, simply is lets the injectors run for the set time from when the ignition is switched on (there is a small trim pot to adjust the time, to short and it may not get the gas vapor quick enough and stall) no point trying to get performance out of an impco 225 on a v6 either, it just won't work as the mixer isn't big enough, the next size up is a 425 but i've read that getting idle and down low performance response doesn't work as well as the 225, so lpg on a v6 with this setup is purely for economy. now the reason i say this is my vr v6 auto engine works great till around 4000 rpm (this is where i found it noticeable), the problem is that putting the foot down to overtake the engine really struggles after kicking down a gear at wot to get to 5000-5500 rpm where the pcm would like it to be to change up a gear after kicking down (fn annoying when you're trying to overtake and the car is sitting on 4700-4800 rpm stuck in a lower gear) simply the 225 is a 225 cfm mixer, 225 cfm is about 4200 rpm for the old v6 when we calculate it's cfm (keep in mind a stock engine's ve is about 80%) CID * RPM / 3456 = CFM 231 * 4200 / 3456 = 280.73cfm (80% = 224.58cfm) up around 5500 rpm the engine needs about 295 cfm, unfortunately impco goes from 225 to 425...
