Gentlemen and ladies

I am now an authorized distributor of Mega-Squirt products.

As some of you no doubt are aware, Mega-Squirt is the first and basically the only open-source, DIY full-function stand-alone engine management system.

Gone are the days of soldering your own boards together!

As a result of my recent discussions with Mega-Squirt's US reps, I have an opportunity to share but need some indication of interest before we (Mega-Squirt and I) can go forward.

Mega-Squirt and I will provide Plug-N-Play engine management systems for NAS Rovers if there is sufficient interest for us to build a minimum of ten units for each of the three main engine management systems.

I am providing Mega-Squirt with technical assistance, ECU connectors, and on-vehicle development (one of the few advantages of owning Lucas 13/14CU(x), GEMS, and Motronics EMS trucks). Once the prototype units are installed, I'll be providing both dyne-tunes and road tunes for RRC/DI w/Lucas 13/14CU(x), GEMS 4.0/4.6, naturally aspirated and supercharged, and Motronics engines.

I do not have any idea as to what the pricing will be (nor do I really care given the opportunity for improvements in every facet of Land Rover Engine Management) but I expect pricing to be in line with Mega-Squirt's other PNP systems.

I have initial requests for one Lucas and one GEMS system.

Who's in?

Depends. What kind of gains are you thinking you'll be getting on an otherwise stock Lucas motor?

sounds interesting, interest would be depend on what benefits it gives. If it will make the truck run better and be more reliable while still staying ODBII and emissions compliant. I'd definitely be interested in if it's not cost prohibitive.

I've never cared much about tuning the truck or getting the most power out of it. For how I use it my current engine has plenty of power. But if it would simplify things and use more readily available and cheaper sensors to make maintenance easier. I'd definitely consider it. I do live in an emissions county though so it would need to stay ODBII compliant.

If it's more water proof, reliable, and easy to source replacement parts then I'm interested. A little performance gain would be nice too.

Not going to happen. And there is little to no gain for a stock configuration engine. You could maybe get away with bumping your timing up since factory tunes accommodate all production variations and unless you are "lucky" yours is probably in the middle of the specs.

I have a miata engine running on MS1Extra firmware and while it is much better than the late 80s flap door air sensor it had from the factory, it is no where near as reliable or dependable as factory mid 90s fuel injection.

GEMS is a wonderful setup, and Bosh has so many dependents on it that swapping to something else would be expensive.

Megasquirt also does some funny things since it is is basically a fuel only TBI controller that has had many band aids applied to it over the years to offer more features.

One "feature" that kicked my butt for a while is the megasquirt resets all of its out puts high then low when it boots. What that means is the coils fired every time the ignition was turned to the on position. There is always some residual fuel in the manifold so you get a nice backfire most of the time when it is turned on. The way most people get around this is by wiring the ignition power supply from the fuel pump supply. The time it takes the relay to swing open the outputs have done their thing and it prevents backfiring from happening. This is not the case with many of the PNP solutions they offer. I had to put a giant kluge of NPN and PNP transistors on the MS board to invert the signal and change some of the settings to work around this.

Megasquirt is a neat toy, but if this is a daily driver, or even something that goes more than 50 miles from your driveway RUN! You will see lots of UK sites hype up the megasquirt. They live on an island and most of their roads look like go cart tracks. I could jog from one side of their country to the other.

If you have something so modified that it needs tuning, un-ass $800 and call Mark Adams.

I don't see any real benefit these would have on a Rover. As restrictive as the Rover fuel injection is, it works, and it works great off-road.

If you're looking to build a lot of (er, more) power in a Rover engine but not worried about off-road drawbacks then just carburetor it.

I think the Mega Squirt is neat. But I don't ever see myself buying one for a Rover.

You have to own a rover first.

You aren't old enough to want to convert to carburetion.
