LPGO, What do you think are the advantages of KDFI over Megasquirt? How is it better for european cars? Is it very similar to the megasquirt V3.57?

For me it is simple, it is cheaper 249,- for a product which is smd (soldered together already) it uses the same software and can do more the only thing it can't do is a steppermotor for an idle valve, but I don't miss that,

The only thing you need is a box to put it in; but for 389,- euro you can have that to and a lm1815 which is boosts your ignition signale when you have the money I reccomemmend this, but I don´t have it either.

take a look at www.k-data.org this is the maker from the product.

A ready made megasquirt is around 300 euro and comes in a casing. It's more than 249E, but less than KDFI in a case, I don't understand why the case costs so much, it must be the lm1815 bit, but I'm not sure why you need this. I did look at http://www.k-data.org but I didn't find much information.

A megasquirt in kit form is only 185 E and maybe takes a couple of days to put together, to me that is worth saving, and in this weather any reason to work indoors is welcome.

BUT, unless you are a profesionel solder-guy a megasquirt doesn't work first time when you (almost) never have soldered (like me). Then you have to buy a jim-stim; 59 dollar + post and package which is a little fake engine in electronic way to check if everything is soldered in the right way and more important if the solder is right (mostly it looks fine but sometimes it looks soldered well but it isn't, well I don't need to tell you that troubleshooting takes a long time then.

So this is why I prefer a ready unit. But when you're good in soldering you can do it your way, but I think a Megasquirt for 185 E doesn't ignition, you have to buy some daughterboards also to make it work in a 2cv.

I'll be honest I never looked really at Megasquirt units, but I know for sure the KDFI runs almost out of the box.
You need no extra parts welded to make it work in a 2cv (1 coil wasted spark)
(sequentail) injection.



Welding all the wires in to the KDFI was complecated (like writing in English (and Dutch to)) enough for me so for me this was the right way.
Maybe for you the Megasuirt is....... I can't tell how good you are with electronics.

another advantage is that KDFI runs with an USB cable a Megasquirt doesn't,
most modern laptops don't have a serial plug.....so a adaptor cable costs more money.

Beside that this isn"t everything you need to buy.... to make it work....

IAT sensor 20 E
CLT sensor 20 E
TPS sensor 39 E
VR sensor 39 E
wireing loom 50 euro
injectors ? 50E scrapyard
injector bungs 90 E
petrol pump, 30 E scrapyard
full pressure regulator 50 E
plumbing an tubing 100 E
lambda probe 175 E (or are you going to tell me you can tune without first time) go ahaed make my day.

So the 30 euro's differents in the ECU is only a small amount (you forget shippinga megasquirt to Europe) at the overall E.

I'm certainly not a professional solder guy, and I'm not very experienced with electronics, I only once or twice soldered repairs to circuit boards, but I would like to think that if I worked carefully it would be ok the first time. What about other people, Adrian, have you tested yours with the stim, did it work first time? Harley, right first time?

The stim is a nice thing to have to tell you it works, but connecting it to the engine will also tell you that. If it doesn't work I don't know if the stim will help to tell you why.

The kit for 185E includes the MS2 processor daughter board that will do ignition as well, I did forget about the cost of postage, but the kdfi comes from a different country too so will not be cheap. All the rest of the hardware, sensors, plumbing etc, is the same for both, and I already have it any way.

By connecting to an engine it could be everything, wires going into the engine,
noise (shielded cable no good) connections and so on with a working Stim it is inside youre Board, I really don't want to scare you, so it's up to the others if it worked for them fine but Harley wrote himself KDFI would be the better choice....... in this topic..




Please let me now your choise.......... and make a topic of it....



p.s. I won't discuss it anymore otherwise you could think I earn money with advertising it.

I couldn't solder my finger up my ass even if i tried! (Old Australian proverb)

I bought my MS1 pre built, i also ought the Jim-Stim incase of trouble shooting, but have never had to use it.

The KDFI seems to be a better package for plug and play style over the MS I & II for people like me who are not competent at soldering/electronics.
Megasquirt has now released its V3 In supporting the MS legacy I will be going down this path as an upgrade to my MS I controller.

Cheers
Harley

I wouldn't be too worried about putting the thing together, although maybe I should try some simple electronic kit first to check my soldering is ok, and I don't think that making the loom would be to difficult, I already modified my bmw loom quite a lot and that was no problem. The thing that I'm not sure about at the moment is what to do with it after it's all together and switched on, hopefully that would be more obvious when I get there.

I looked at all the things that the MSIII can do, I don't know what most of that is so I think I don't need it. Just so I'm clear, the MSIII is a new processor, right? and you can plug it into your existing main board? one of the main boards is the v3.0, They did make it a bit confusing numbering both.

You see here where it starts what do you need, again with the Kdfi you've got a finnished product with all the goodies you need, I can't help you what to buy with Megasquirt.

But another tip for you wenn you want to solder something solder a Lambdacontroler so you can see for yourself if you can solder, you can use it already in your existing engine's to see if they are right tuned or not.
