Whats Your fueling preference.
 

Next poll for our demographics...

What would be your prefered fueling system.

EFI For me :)

TT

Will probably start with bike carbs but would like throttle boddies one day.

Just fitting a 2.0 pinto EFI

Realy there should be no need for selectable maps.

Hi David
What mod have you made to the EFI to fit in the roadster?

NITROMETHANE

Ray:)


you cant beat bike carbs for bang for bucks

None....
When I get my computa back I'll post a pic.
But I am gong to need a bonnet scoop of some sort to cover the plenum.

of course the ultimate n/a set up is roller barrel t/bs with fully mapped sequential injection
Ray:)

Right, as the Megasquirt manual puts it, the throttle pedal is the map selector.

Carbs must disappear like the rotary dial phones and cassette players did. There is much better tech for the same purpose, we're 1/10 the way through the 21-st century!

Here ya go Frankie.
Forgot I posted this last week

Cool Not to much coming out of the bonnet. Burton do some scoops in versus sizes had one on my old bonnet.

My brother in laws missues has a 57 plate Skoda with a tape deck/radio.. I could not belive it!!! I thought it was bad in my 02 Galaxy but at least that has an autochanger!

Carbs = K.I.S.S. Simple works for me EVERY time.:p

I'm fitting bike throttle bodies (from a 600 Honda summat), got two sets which easily split into pairs so I can run three pairs straight down the middle. Got to make up an inlet manifold yet which should be fun. I then plan to use an Emerald ECU for fully sequential injection, just got to find one at a sensible price.

D.

Any reason for sequential? Do you have a cam phase sensor?

TT

Missing option
 

This poll is missing an ........ I aint got a friggin clue option !!?? :o :D

Seriously though, my roots are firmly rooted to the carb era, that said, I very open minded about all options.

I guess that is why I have a collection of the following: Original stock ecu, megasquirt, megajolt, stock injection, bike throttle bodys, bike carbs, access to a pair of twin webbers if needed & heck I even have a pair of Stromberg CD150's kicking about ( Yeah I know they were crap ) :o

Who knows what my build will eventually end up with :confused:

I started to look into making my own throttle boddies a year ago when I had access to a lathe and milling m/c. It can be done very cheaply, even bought brass sheet for the butterfly's and brass rod for the spindles. Block of aluminium offcuts are not expensive. Would have to source linkages and springs etc. but using bits of old SU's or such like is a possability.

Anyone in the Rugby area with machining facilities willing to give it a go?

Throttle bodies and megasquirt - 1st option

Bike carbs and megajolt is a good cheaper alternative though, as long as your not worried about fuel economy.

For Phase 1- IVA - bike carbs and Megajolt for ease of emmissions tweaking
Phase 2 - engine change - bike carbs & Megajolt
Phase 3 - megasquirt

That sounds like a nice progressive plan to me David :cool: :)

As for me !! ..... Going to have a crack at running the Zetec with the stock ECU & re-worked inlet manifold.
Mainly just for the challenge & in the full knowledge that this is probably not the best performance option ;)

If it all goes tits up ?? ..... I guess, throttle bodies & Megasquirt ..... or will I !!?? :rolleyes:

Bike carbs on errrr......












.....a bike engine!

Why not try a 2e3 on a bike engine to be different ;)

TT

Bike carbs and megajolt :D

I would definately prefer throttle bodies and megasquirt once i go zetec, but as spud says bike carbs and megajolt is much cheaper and easier to do if you dont mind it being a little thirsty. I ran a big power 300zx tt for a year that only did 8/12mpg :eek: so that doesnt bother me.

Thats why its so popular, its a good point about power outputs by adrian though would be nice to see what result bike carbs will have on various engines especially a humble 1.8cvh (thats what im using)

thb i will be happy if it achieves 100bhp any more is just a bonus :)

That will do for a while until the zetec conversion next winter

I'm sick of pestering Handy:

SO,,,Mark get on with your car instead of posting.......;)

I'm not going to Teesside track day with the only Haynes

Some of us have to work for a living you know ;)

Not just tinkering with sports cars and making top secret body work!

Well i say "work" if sitting in the office browsing the internet counts :D

Dont worry im doing my best to get my car there too

:D :D :p :D

so am I :eek: :eek: :D

Mark.... thanks for the valve you dropped off last night :cool:

cheers
andy

I'll be running a set of R1 throttle bodies with megasquirt on the redtop.

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 .

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:
