New link LEM

[RomanV]

Why oh why would they design this fancy new ECU, with all of these features, and then give it only 2 injector outputs?
It doesnt make sense to me, even on a 4 cyl engine, not to mention a 6 or 8.

I know that it probably doesnt matter a huge amount at WOT and high RPM where the injector duty cycles are high anyway, but... it just seems wrong.

Firing two injectors at the same time is just plain.... rangy, I doubt the factory ECU on my car does that, and I dont plan on taking a step backwards from what I've already got.

*sigh*

I think I understand why some people are so insistant on motec etc.

Awesome news about the LC1 then.

But what kind of connections does it have on the end of the cable?

A serial cable is supplied with LC1 when you purchase it. My lappy only had USB so i had to get an adapter from dick smith is all.

Keep in mind its an LEM, not a Link Plus, if you actually want fancy, then the G2 Link plus is the product for you currently

You car may have four wires from each injector to the ECU,
but most of them are only fired with two outputs anyway.

The V8 supercar team dad worked for used to run sequential injection and used to tune and time each cylinders fuel individually, and there was a difference that was just measurable, less than 1% ( 6hp in 600), and so is it really worth it?

Having pulled my wireing loom apart to fit my Link I can tell you Mr toyota runs 2 injectors together in starlet Gt's standard

As above, the LEM is supposed to be the basic entry-level kind of aftermarket ECU. What does a basic Motec retail for? I'd guess the price would be more on par with a G2 (standing here waiting to be corrected).

M4 Clubman (poor son Motec), goes for $2250. A smidge more expensive than the G2 in fact

id take the motec even if it was sligthly more expensive

Why, whats your reasoning behind that?

and thats just there base model
it just gets better from there
they also offer telemetry and the OMFG how trick is that MOTEC dash
i guess the new links are a bit better than there predesesors

but IMO they priced themselves out of teh game tring to compete with motec and aurtronic


just out of curosity have you ever seen the motch sofware and link sofware side by side ??

thats enough by itself to pay teh extra biccys

[vvega]

id get a comparason for the g2
but sadly the link website is down......lol

[Crucible]

Well Ive just brought the new G3 through NZEFI.

Has the launch/flatshift features which I was after, also has boost per gear but you can only use one or the other because It only has one digital input.

also only has max boost of 22 psi, but thats about all I need.

to run on my 4agze I also needed dual channel ignitor to run waste spark and a compatable air temp sensor.

They done me a good package deal with a 500hp Walbro also.
NZEFI are good to deal with, the guy there Nick was really helpful.

[flygt4]

max boost of 22psi is only limited by the map sensor isnt it?


and on a side note , the angry old man is back in force welcome back vvega

[slighty_sykotic]

And being that the g3 and g2 are the same platform, I believe you might be able to transfer maps from one to the other? So you start with the base g3 and once you need the extra inputs and outputs of the g2, and a higher boost you can buy the g2 and transfer maps.

And I believe the resolution is now up nearer the motec etc now, as well as the "boxes" are adjustable.

And a side note, its confusing that the higher spec model as the lower number (g2).

I dont think its about spec... the G is the generation. LEM and Plus are the specs. The LEM G3 just happens to be released before the next generation Plus version. I suspect because its easier to test fewer functions.

Resolution is user definable.

[slighty_sykotic]

Are you sure? I was lead to believe the g2 and g3 shared the same platform.

Could just be certain people talking out their arse

Are you sure?

Yup

The Motec Software is very good, ive used it alot. There is no question what motec offers is top notch although the base model M4 is still Dos based.
Motec Datalogging is brilliant although you need a big budget if you want to get real serious with it. We just fitted out a NZV8 touring car and the parts alone were $12,000.00. Obviously you can do a base setup but youll still be looking at around 4g by the time its installed and setup.

I dont want to get into a big debate about whats good and not etc.

As far as im concerned its very hard to beat Links current platform for what you get for your money. They havent priced themselves out of the markett at all. As for the spec sheet you put up the new Link range is actually very comparable. Just because Link dont list alot of things doesnt mean they dont have it. They are just realistic that most people dont actually care about the little things.

One other thing i would like to say is, i cant for the life of me work out why so many people have Microtechs? Has anyoone here had much to do with them as I find them Junk.

[slighty_sykotic]

Ok, ill beleive you then


So the g2 is being dumped as soon as the g3 plus comes out? hasnt been out long has it?
