Its back with the Emerald

[hiltonig]

Finally I have it back with the Emerald, its great through traffic no shunting, excellent pick up, makes a great difference. so if you thinking about it dont !! oh and a wideband lamda is optional unless you want close loop or tweeking . me i just want to use it

now wheres my 5.4 with sc kit........... watchout thenick

Good news! The green corner gets bigger....

Howa yours running pupp ??

About there I think, in near daily use and running pretty strong. Only glitch I can think of at the moment is a tiny bit of hunting immediately following 'cold' starts now the ambient temperatures are a little higher (it didn't do it when things were chillier)... not spent too much time on trying to sort it as it's only an issue for the first minute or two of running but will only be a matter of trimming the cold enrichment at the right point (albeit it is a pain from work where I have a gaggle of sleeping policemen to negotiate).

Very pleased with the outcome

Nice one Nigel! Whens the 5.4 going in then?? I've finally ordered a charger for mine after 2 years of umming and arring, not sure I'll be able to keep up with you though!

[rev-erend]

Nigel,

Welcome to the modern world..

It's a much better system than the old Lucas ECU ..

Glad you like it

Can't wait to get mine on the road again.

[blitzracing]

Im still goint to ask the question though- anyone got one of these through a straight MOT without an emissions failure ?

Yes, with the cat replaced and a higher idle. Mine has an idle issue where it's getting too much air in currently that needs sorting, mechanical and not ECU.

It was witha sympathetic tester who was prepared to help sort, on a deliver and drive away basis it would most likely have failed.

[rev-erend]

Mines is made in 1990 - so emissions are not a problem ..

[blitzracing]

Fair cop guv !

[hiltonig]

Yes its much better than the lucas and dizzy, I went for the range rover coil packs so it looks neat. I too have a small problem with Idle when cold, after a couple of mins its fine. I had mine mapped at Emerald and it took them a couple of hours to sort a missfire problem which turned out to be nothing more fouled plugs due to the supplied base map which got me to the rolling road.Emerald have suggested adjusting the throttle stop position to help the cold start issue. They also suggested not to bother using the Lamdas as he has very limited sucess with the Innovate type. Bit of shame as I fitted 2 of the innovates. Anyone else had this cold start issue ??

Emerald have suggested adjusting the throttle stop position to help the cold start issue.

Is it firing OK and just too slow, or missing/stumbling? And, what form of idle speed control do you have? If you have any form of active control then it's possible that it doesn't have quite as much authority as it needs for a cold start. In this case lifting the throttle stop a fraction would give it more authority and probably cure the problem. If it's missing then it is more likely to be the cold start enrichment not set quite right and perhaps need a little experimentation to see whether it wants more / less fuel.

Mine was at V8D when the MOT came up.

They managed it. It's a 1994 500 Griff with an H404 and 330bhp.

But it does get tested as non-cat.

Has anyone managed to get the idle air valve problem sorted. Mine is ignition controlled idle at the moment.

I have finally got the right air valve. Emerald supplied it, but it's a Ford part.

But it needs an adaptor plate before it can be fitted. I have a design in mind, will take a few photo's and talk to CliveF. If it works and there is a demand then hopefully he can make a batch.

[hiltonig]

I dont have a air control valve as they didnt see it neccesary, I wont idle from cold until say a min when a bit of heat is in the engine then its fine. I may adjust the throttle stop screw. I did ask Dave walker at emerald and this is all that was suggested. Anyone else have a Idle valve

I use a GM 2 wire valve inline in the oem bypass circuit, with the original stepper removed and the hole blanked. I'm not wholly confident the valve itself is funtioning presently (rather thibnk it isn't) but have not spent any time checking properly as it's only an issue for the first minute of running

That sounds just like mine (no stepper) when I was still using the hotwire setup. It was a bit marginal for the first few minutes on freezing days and needed a bit of help at first. The current setup gives me mapped ignition and I've put a load of advance in below idle which stops the revs dipping too far. With no active control at all it idles pretty steadily hot or cold, just sitting on the advance curve.

[thenick]

I swear Dave says this just because he's lazy..! I run the two wire bosch type on the throttle bypass pipe with the old stepper hole blanked off in the same way as Pupp. Mine has always worked spot on and is very easy to use and setup. Valve was bought used for £10 off Ebay and only required a slightly bigger bit of pipe to plum in. It sits neatly behind the plenum top and is controlled by either manual or mapped control. I tend to run it quite far open from cold which keeps it running nice with a quite fast idle from cold. This warms the car up quicker and keeps the idle nice and strong. This then shuts 90+% when it warms up and turns control mostly over to idle ign control.

It's worth putting one one as it's very quick and easy to do and just makes it run that bit nicer IMHO

I'd say its the other way around .. using an idle control valve is the lazy way as it allows you to be not so accurate with your warm up trimming and still have an engine which idles from cold start. It's perfectly possible to get an engine to warm up just on a coolant trim strategy it's just that it's a bit fiddly and time consuming doing the trimming and seeing what the difference is .. fitting a ICV is a fast-track method for the lazy, not the other way around

[GreenV8S]

My main problem was running out of input/outputs on the MegaSquirt. Being able to get away without any idle speed control at all was a nice surprise, but controlling the idle speed on the ignition gave better manners. No doubt having active idle control would be even better (as long as it does keep working reliably, unlike the hotwire stepper which seemed to need regular tlc).

[Pupp]

I just kept the bypass circuit because I didn't want to have to figure a way to plug the two apertures although I'm absolutely certain the ECU can be set up to give good cold start without.
