Sequential because when its properly set up it works really well, cam phase sensor, hmmm, not sure to be honest but I'm sure if there isn't one I can come up with something:D .

If Ronnie had his way it would be petrol/parrafin with magneto !!:p

:D

What's wrong with steam ?? :o

I used to milk cows as a Saturday job when I was at school & used a Massey Ferguson T20 to take the Milk churns up the lane ....... Do you think I could ever remember to switch back over to petrol before I turned it off ...... Oh yes it was a hand crank jobby, none of that new fangled electric start :o

OMG ........ It's just dawned on me just how old I am !!??

Can beat you on that one of "being old,I restored the petrol/parrafin engine and mag a few years ago and in the 80's I rebuilt a 36 Daimler Light 15.

As for steam.....

Got to give you that one mate :)

I surrender ............ You are considerably older than me :D :D

Just offers little tangiable advantage over batch fire, unless your planning to impliment a cylinder shutdown stratergy during light cruise.

For sequential to work correctly your going to need a cam sensor so that the ecu knows if the engine is on a intake. Zetecs and Later I4 based units should have a cam sensor.

If you can get it to work with little effort then go for it.

TT

The stock ECU should be fine for getting the engine going. The only potential issue is that if you have significantly changed the intake/exhaust system, you may start to run lean. That should be easy enough to sort with an adjustable pressure regulator and a Lambda

Generally, you don't tend to see massive power increases between carbs and efi - what you see is better power across the range. I.e. because you have limited adjustment within the carb, you often have to sacrifice some areas of the power curve to give you max power. EFI lets you tune the whole of the power curve - the correct term i suppose to use is improved driveability - i.e. more power low down while maintaing top end performance.

I've been lucky enough to have had the chance in a previous job to spend a couple of years playing with DTA and Motec ECUs on a proper engine dyno. Interesting that about 90% of time was spent messsing with the setup rather than actually mapping. Electrical gremlins are a nightmare - cause more problems than anything else. Then you often found that the most basic setup was not done with care - sensor relations, throttle balancing etc. It always surprises how few people run a lambda sensor.I am going to try one of these units - http://wbo2.com/2y/default.htm and see how it goes.I have the problem of being spoilt and having had all the toys before that someone else had paid for!!!

Here David, that wideband lambda kit looks quite cool :)

I wonder if that would interface with the Megasquirt system ??

Being as I value your advice mate ..... Do you think that I will be aiming a bit high by doing the following....... 1.8 115bhp Zetec, 2 litre cams, 2 litre throttle body , 4 - 2 - 1 exhaust & modded inlet manifold .... All on the stock ecu

I have not got a clue if the Ford ECU is tweakable ( Somehow doubt it though )

ronnie it is pointless doing any of that on a stock ecu as it wont magically alter the map. i would just go with the megasquirt to be honest. you have done the hardest bit which was building the thing wiring it up shouldn't be any trouble

Hey Ronnie.
Don't you just hate it when people dismiss wiring as the easy bit !!!:rolleyes:
