Link ECU

WiM · Post by **WiM** » Tue Nov 01, 2005 4:11 am

Guys, and the ladies,
Question about the Link ECU. I know it's been made in ChCh, and that
Flyin'Miata uses it for it's FM kits. Now, from what I understood is
that if you buy the Link from Link Co in ChCh you get the Link with
all the bits and pieces cheaper than from FM. But if you want to get
the best information you have to tune you need the Keith and Bill
from FM.
Does FM has their own chip that they build in and can you purchase it
from FM?

Link also do a more generic unit called the LEM. Has anyone had any
experience of using this. (I am not planning to take the turbo path)

Cheers guys,
Like Euen I am actually thinking at using the Link without a Turbo. I
want to be able to finetune the engine to get better (less) petrol
consumption AND higher performance thru this Link ECU, not sure in
this case if I need all the knock sensors and bigger fuel
injectors, ...

The knock sensor is probably only an issue with a turbo as due to the extra
fuel and air there is a risk of pre-ignition (knock). Thus on Turbo set-ups
the timing is actually retarded. But on a normally aspirated car with a link
ECU you can still use a timing light to get your timing set right and in
fact can run it a little advanced. Some people have problems with knock
sensors as they can cut in when not wanted, and this will retard the timing
and kill the power. If you are really unsure it's better to pay for 30mins
dyno time to check for this and your fuel/air ratio at the same time.

The advantage of the full link with the FM software is they have a standard
map (fuel/air) program for almost every set-up. Thus less heartache inthe
set-up.

Hi Guys,
very interesting following your thread. I was wondering what kind of gains
horse power wise you are expecting from such a modification??

Peter,

Not that much in the first instance.

I am expecting about 15bhp. About = of this will come from removing the MAF
and going to a MAP sensor (The MAF is extremely restrictive), the other = from
the timing / fuel etc. This is backed up from dyno runs that others have
done. Another advantage (as mentioned) is the improved throttle response.

So it is not really great $$ for HP - I am sure that there would be better
options as your first step. On the other hand - it looks really cool (but
that's just the nerd in me) see - http://www.cardomain.com/ride/2088142
<http://www.cardomain.com/ride/2088142> (page 6)

For me, phase 2 (about a week after) will be to 'turn on' Sequential Fuel
Injection. This will improve throttle response at light throttle openings.
No BHP added here. Why am I splitting this out and not doing it at the same
time as the installation? I am following the do the basics - test, make a
change - test approach. This probably should be done at the same time as the
installation.

Phase 3 (about another 2 weeks after I have had more exp. learning with the
Link) will be installing the larger injectors (I love ebay - saved a fortune
over buying them in NZ) - I am unsure of the gains here, but it is really been
done for preparation of the turbo installation.

Phase 4 (before Xmas holidays) will to be add the turbo (and associated
clutch, etc etc etc ) - all indicators point to approx 220rwhp.

Hope that this helps

C

Its going to be an interesting project Jeff. I have to create a new wiring
loom for the car anyway so having to wire in the ecu just adds a bit more
variety. I'll probably have a little less hair when I get it finished.
Depending on how successful it is I will try and put something together for
the magazine. (Don't hold your breath, Nigel)

Has anyone had any experience with A1 Turbos?

Hmmm, Quad throttle bodies, theres an interesting thought... The sound
of 4 independent inlets on a well tuned engine is one of the nicest engine
notes ever

In answer to Peter Garrity's question, I am looking for a bit more
flexibility in tuning. Also, as my project car is not actually an MX5, just
using MX5 mechanicals, the prospect of getting rid of the airflow meter and
gaining a bit more room under the bonnet is appealing (the LEM V5 uses
Manifold Air Pressure instead of using the AFM) Removing the AFM also
reduces a bit of restriction on the amount airflow into the engine and as I
am staying with normal aspiration, every little bit helps.

What car are you building? I would be interested in a few details?

Hi Ian

The car is a TG Roadster, a replica of the 1955 TF MG but it uses all the MX5 running gear.

Have a look at http://www.sportscars.net.nz/

Hi All,

I have a set of NZM 16" alloys (Mags) that are in excellent condition
with near new Bridgestone Potenza GIII performance tires on it. You can
see them on http://www.cardomain.com/ride/2088142 .

I am wondering if anyone would be interested in a swap - I would like to
move to a set of lighter weight 15" units. Style open.

I am happy to come look in Auckland or the Waikato.

Thanks

Chris
