For an example of how they can look see http://pub.se7ens.net/lists/cam7/Xflow_TBs.jpg

That is a very neat job.

Bill, do you know what TB's they are and where the carbon ram pipe came from?  Any other pictures would be a help to.

Cheers

Hi Bill,

Im currently collecting bits to do a injection conversion on my xflow, using Megasquirt, and also Megajolt when it comes out.

Anyway, i was wondering what Bike you get throttle bodies suitable for a xflow from??  And where i could buy a set?

cheers

hi bill  you got me interested  ,thinking of going to thottle bodies mega squirt sounds like the b*****k*.have you got more details.does it just do the injection side or ignition side to.is there anyone in south england who got one in westfield.are they hard to map .

are they hard to build.

can they be supplied ready built.etc etc.     more information wanted

[hilly]

Have a look here for the MS Yahoo site.....

There is also a UK page

If you can hold a soldering iron then you can build one with a little patience or just get one ready built from Bill.

I live in the southeast (Surrey) and have got one in my Lotus Esprit .

If you are an average DIYer then fitting the injection set up should be no problem.

To map you really need a WB Lambda, I tried with a narrow band an got OKish results but after borrowing a WB unit from Bill (he really is the EFI god here) it has produced fantastic results.

Check out the URLs and you will soon be addicted

MegaSquirt is only fuel, you'll need some kind of ignition system also. MegaJolt is that system, but it's not ready yet.

[bill shurvinton]

I'll give full info tonight when I get home.

Basically though, built units are available. Loom making services are available. Ignition control is available, either wasted spark or through a dizzy.

running 2ltr vauxhall lump with webber alpha 3d ignition at moment with 45 webbers .wish to go injection route soon.have got webber oxygen sensor readout fitted already [believe this is wide band] can i use this .can the other sensors be shared with the ignition  unit ie thottle pot ,air temp, water temp or do you need to double up on the sensors.

cheers pete

Bit of catch up required.

Andy: goodness fancy seeing you here :-)

The pimpy carbon throttle bodies was done by Col Rulle, who I have been told hangs out on the stryker lists. Don't know if he does this  as a living or just for good mates. I do however know of someone who is planning to do adaptor kits and will try and get some prices and timescales out of him.

For under 200HP cars, the GSXR600 TBs are the best. For more HP the 750, 1000 and busa are better. Both types are tapered, with 45mm butterflies on the bigger ones.

Built MS will come out at around £160. Can't tell exactly as I haven't had the first 5 shipped over. I also have 8 or 9 kits coming in, of which a few may be available once I have dealt with back orders.

In terms of assembly, getting looms made up, tuning advice etc, I can offer words of wisdom and help and even the odd demo up on my hampshire hill, but if you need someone to do the install, I can send you in the direction of Guy Hill, who not only wrote a chunk of the code in MS, but is a very handy spanner wielder  and wiring person ( and also looking for some additional income at  the moment).

It can share sensors with a few mods to the input circuit and recalibration

'how easy to tune' Difficult question. I think it is easy, but I've been doing it for a while. Like any ECU  there is a learning curve, but unlike any other there are about 3000 people out there willing and ready to help you out.

Hope that covers some of the questions

Bill

[Mike-SEiW]

Bill - thanks for the informative reply!!

Do you have any experience of the MegaSquirtNSparky? What exactly is that? A build-on card, separate box or just software mods?

[bill shurvinton]

Just a SW change and a couple of extra wires. Oh and a welded up dizzy

The SquirtnEDIS uses a ford wasted spark module.

[Neil Purdie]

probably a silly question.  What is a Wasted spark system made up of ?       What was wrong with dizzy and points,

Neil

[bill shurvinton]

Wasted spark is when you have a double ended coil that fires cylinders on alternate cycles. Dizzys can work very well, but you can do things with mapped ignition that are well worth while. Just look at how the fuel economy goes up on Xflows with mapped systems.

For peak power, a well setup points system can be as good, but as I spent a lot of the drive into work this mornign on 3 cylinders because it was so damp I don't like them meself. (knackered old golf, can't be bothered to upgrade it to EFI.)

[dasamdy]

For those interested I can supply photos of my installation if you PM or mail me direct, I've managed to do it for just under £500 , but a fair chunk of that was for the DTA ECU (£350)

The work to adapt the throttle bodies is quite specialised but not too difficult (but then I have access to hundreds of thousands of pounds of machinery and equipment at my disposal) but I made mine without doing any welding

I can also help people who are going this route or have Jenveys, or those with bikes infact, with Vacuum gauges, a set of four I can currently do for £45 including mounting plate and hose adaptors and the gauges are all guaranteed to be accurate to within 2% so plenty good enough for balancing throttle bodies and much more user friendy than a single syncronometer!!

I currently have orders for 2 sets, if I can get enough interest for 10 sets I should be able to get them down to £42 + postage (or free delivery to selected speed events)

Any one interested e-mail me for more details

Cheers

I've seen the work Dave has done on these, they are first rate. This guy is a genius on a CNC. Have a look at the ARB linkages on my little red 'un, if your ever in the paddock. All made by Dave. If they weren't bolted on, they'd float away
