Discussion
I have been thinking about going the Megasquirt route when I get my car back together. Was going for fuel and ignition control, wasted spark, on a 4ltr sep engine. I see a few people have mentioned that they will be going this route but has anyone done it, was it easy, any particular problems to overcome. Hoping that this could become a discussion. I know that there is the megasquirt pages and forum but not to much mention of rover v8 conversions.
It wont be easy dont kid yourself it will be,,,,,BUT when you have fitted and set it up you soon forget the hard work and boy will you notice the difference,response & pick up will be much improved,mapped ignition makes a huge improvment over the old bob weight dizzy

Well Ive just picked up my megasquirt yesterday, Im gonna go wasted spark with a wideband lc1 sensor. Ive got a john eales crank wheel and sensor and im gonna wire it mostly through an old 14cux case that been butchered to get to the pins so to use the standard loom connector.
Ive been asking about it for ages but didnt get many responses on here but speak to Phil Ringwood www.extraefi.co.uk and see his cobra site build then you will be taken. Im just gonna have ago and see what happens.

Phil and I worked on just such a ms/lucas hybrid project on my V8S .. if you're sticking MS onto an RV8 you need look no further than Phil (dax tojeiro on here).

When a car is sold from new it has to pass the latest emissions requirements, an air flow meter helps them achieve this as they tend to measure air into the engine pretty accurately and cope with engine to engine variations very well.
Now you own the car all you have to pass is the MOT emissions which are laughable by comparison to the manufactures test, so the simpler method of using throttle position or manifold pressure for engine load will suffice.
Not only that throttle position method tends to give superior throttle response and is very easy to map, both considerations for a DIY installation.
Go and do it you won't regret it

ive just mounted my wideband lc1 and Ive removed the standard sensors that im going to keep just in case it goes back to standard. Does anyone know the size / thread i need to get 2 bungs now. Or does anyone had a couple of old faulty sensors???
Thanks
Neal
Neal Thanks

You can have my old knackered sensors, which I used for the same thing, TVR has been sold now! Email your address and I'll get them sent next week. Definitely moving a damned sight quicker than me on this project!

http://www.lambdasensor.com/main/mwide.htm This seems to be the place for the sensor...
I am also looking into this route at the moment and am trying to price it up properly but am having trouble as i'm not sure what I need! Currently i'm looking at Emerald but Megasquirt is also in the running and I guess this applies to both - what EXACTLY do I need to have the system running in my car? I've just spoken to a woman at Emerald and she wasn't entirely sure but seemed to think it was just:
- ECU
- Trig wheel/crank sensor
- Throttle pot (but can use old one)
- Air/water temp (can use old one)
- Coil Packs
Interesting as I thought you needed a wideband Lambda sensor but she seemed to think I didn't... Is this true? If it is then fine, if it isn't, then what setup do I use? Remove original lambda sensors, bung holes and replace with a single wideband screwed into the downpipe?
The Emerald lady also said there would be a discount if I purchased with one or more others if anyone is interested?

Where is the best place to mount a wideBand sensor if you are only having 1.
Anywhere convenient, it isn't fussy. Just make sure it is not anywhere that water inside the exhaust can dribble into, so if mounting in a horizontal pipe put it in the top rather than the bottom.Presumably it has to be before the cat, could place it next to one of the existing sensors or is it better after both sides have met. I assume that the size and thread is different to the existing sensors and that is why you need another boss.
Is there a problem leaving the existing sensors in and just not using them.
From the prices at http://www.lambdasensor.com/main/mwide.htm it would see silly not to use a wideband sensor with a better ecu.
