Nodiz ECU

[StrawberryCheesecake]

Is anyone out there using one? I know a few stock car racers who are using them with Zetecs. It's a nice neat looking package and dispenses with the EDIS box and Ford ECU. Complete kit with loom and starter map is £300 in the UK.

Any experiences out there? Are they robust and reliable?

You have me curious too...

The Locostbuilders in the UK seem to like the Nodiz, but at the price they're wanting it's a bit spendy.  £300 equals roughly $425 US or $570 Canadian.  A Megajolt on this side of the Atlantic is at it's most basic $145 US ($195 in Cdn Peso), but it does mean sourcing an EDIS unit.   Have you looked at the Canem unit as well? Again kind of pricey, but I haven't read any reviews on it.    I wish Brent Picasso and the guys at Autosportlabs would develop the MJ unit into a standalone like he Nodiz.

In my opinion, the difficult part of an ignition system is driving the coils.  The advantage of a Megaspark is that it uses the EDIS to do that with all of its OEM engineering and reliability.

The electronic parts that make up DIY setups like this are usually not automotive rated.  Some times it doesn't matter, some times it does.  I like to treat anything unrated or suspect very gently, protecting it from vibration and heat.  For Megaspark that means a soft mount in the cabin somewhere but the EDIS can be placed in the engine compartment (similar to OEM position mounting).

But we all know what opinions are like...

All valid and reasonable comment I think. I've heard of coil drivers failing in Megasquirt setups, although I'm told that's often because the installer used one of the two drivers, rather than spreading the load.

Nodiz seems to have advantages in weight, size and ease of installation. I'm sure Mr Chapman would have approved of the first two at least. I'm leaning towards giving it a whirl.

Soft mounting seems like a good precaution. I was planning on putting it in the cabin for protection, as well as adding security switches.

The link above is the system I'm looking at.

Honestly, I would not do it.  I went down a similar path for my Zetec using Webers and a Megajolt system.   Megajolt was rock solid, but if you are looking for streetable Zetec performance anything short of fuel injection will drive you crazy.  After five years of jetting and logging AFRs I finally gave in and bought a turn key OMEX system.   Dumping the Webers and getting a fully sorted and balanced ITB setup was the best decision I made.

With the OMEX setup you can have multiple maps.  I suppose one could reprogram the ignition to advance too early and set up flat spots in the fuel delivery and an overly rich idle for that vintage Weber experience

All fair comment, but I don't want to go injection for a few reasons.

- carbs are an OEM period feature, and are reliable if they're in good condition, and you can keep dirt out of the fuel

- I don't want a high pressure fuel system, for reasons of complexity and fire risk.

- I think carbs will deliver more than enough performance, and sound great doing it

- I've already got most / all of the bits, depending on how many jets i need to change.

I know what you're saying, but I feel compelled to say that the original carburetted, low fuel pressure TC was a fire risk with the plastic fuel tee at the carbs which eventually cracked letting fuel drip on the exhaust! Several TCs met their fate in that way.

Be sure you use good quality rubber hose with metal fittings. I would argue for stainless steel braided hose with AN fittings for the durability and looks - but not the price.

An EFI fuel system is a bit more complicated but with an in tank fuel pump, the right hose and fittings it is probably more fire safe than any carburetor setup.

I think NODIZ is a good system, I have done quite a bit of research and decided on it for when I will be building my wedge head renault engine.

All fair comment and good advice. No plastic bits will be used, for sure. A mate is one of the family who run Think Automotive, so I have access to the right bits at friendly prices.

You can't beat the right bits at friendly prices!
