I'll be able to check for ID tomorrow and get back. Derek

I'm guessing it's running the 1.6 injection inlet manifold then but i doubt if it's still running the 1.6 ECU, not without a superchip or a remap.Can you see the ecu to get any ID off it ?First we need to work out what system it's running, then you can get the appropriate manual.Jim From: Derek Clews Sent: Monday, March 05, 2012 3:22 PM To: quantumown...@googlegroups..com Subject: Re: [Quantum Owners] Re: Rev CounterI'm out of the house at present, But its injected with EFi written on it, so Ford by the look of it. The 'distributor' section is very different from our other Q's with carbs, so a coil pack. The previous owner was a bit vague about the origin of the engine and it was changed to a 2L on the V5 (It had been a 1400 cc!) when I took ownership at one stage I thought it was a Fariday 1900 cc but it seems not. (It had been a 1400 cc!) All that said it runs better each time I take it out and sounds very nice.I would like to know more about the EFi system as I am new to it. Any suggestions for books or other useful info? Would e.g.and XR3i Haynes manual cover useful stuff or be misleading?Derek On 5 Mar 2012, at 14:51, Jim Hearne wrote:Yes, the 1.8 in the Sierra was the biggest in the UK but it's also quite different to the FWD 1.6 CVHYou might have a overbored and sleeved 1.6 block, a overbored and modified 1.8 block, or a 1.9 or 2.0 block from the USLook for a cast number about 20mm high on the front of the block, that should show you the original capacity.Has the car got a carb or injection ? Has it got a distributor or coil pack ? After market or Ford ECU ?

I'll have a look at the paperwork, but I have taken over someone else's project so I don't have much back ground personally. Its a 2L CVH so probably not very straight forward. I don't believe any UK car was fitted with them. 1800 CVH in the Sierra was the biggest wasn't it?Derek On 5 Mar 2012, at 12:51, Jim Hearne wrote:At a guess, the rev counter has been connected to one of the 2 coils on the coil pack.So it's only seeing half the sparks. You need to connect it to the rev counter output on the ECU.Tell me what the wiring loom and engine were from, car and year, and i should be able to tell you what pin on the ecu it is.Jim From: Derek Clews Sent: Monday, March 05, 2012 12:09 PM To: quantumown...@googlegroups....com Subject: Re: [Quantum Owners] Re: H4 Rev Counter Jim,My project Bronze Qoupe has a similar but different issue. Standard clocks but now a 2L EFI engine fitted and it reads at half revs. Either that or is an amazing engine.............! What do you recommend?Derek On 5 Mar 2012, at 09:20, Jim Hearne wrote:But, wasn't yours a 2+2, hence Mk2 Fiesta instruments which expect 4 pulses per engine rev, just as the Zetec ecu puts out. It was the distributorless CVH engines (Mk3 Fiesta, Mk5 Escort) that for some reason Ford decided to connect the rev counter to one of the coil wires which since there are 2 coils only gives 2 pulse per rev.They changed the CVH rev counters to match this.Probably was done as the late carb'd CVH's with the distributorless ignition didn't have a rev output from the ignition only ecu.Then they carried that system onto the CVH injection.When they did the Zetec they went back to normal but with a dedicated ouput from the ECU, as this wasn't on a coil connection they could also do away with the suppressor.Jim From: Mark Miles Sent: Monday, March 05, 2012 9:13 AM To: quantumown...@googlegroups.....com Subject: Re: [Quantum Owners] Re: H4 Rev CounterI am now confused, when I did the transplant I used the cvh clocks with the zetec ecu, All I did was connect the output from the ecu to the old coil wire that fed the rev counter. This gives me the rev readings that I would expect, idle at just below 1000 etc. Could this be something that varies with the ecu type?Mark Mark Miles Manager Bar Square 8 Market Place Wokingham Berkshire RG40 1AL 07565 110439 From: Jim Hearne <j...@quantums.info> To: quantumown...@googlegroups....com Sent: Monday, 5 March 2012, 9:02 Subject: Re: [Quantum Owners] Re: H4 Rev CounterThe CVH engine with the distributorless ignition drove the rev counter from one of the 2 coils wires.. The Zetec runs it from a dedicated output from the ECU, if you connect that to the CVH rev counter it will show twice the revs. If you are still using the CVH main wiring and instrument cluster then you can switch the rev counter connection back to one of the zetec coil connections and it will work fine (keep the CVH suppressor in circuit).What combination of wiring looms do you have now ?
