LOL

That was what i meant

The retard features, MAP and TPS voltage modification are more relevant to turbocharging a normally aspirated Subaru and not needed if you have an aftermarket ECU.

We can also get a 1/2ch Version 0,which only have knock retard ,this is priced at 450$

thank you Harvey and skassa.i have understood.
it's a strange management to waste a spark each time.
the system cannot advance ignition more than ecu

quote

Charly:

Unfortunately, it can only retard.

On the Subaru, the unit triggers on the falling edge of each ignition pulse.
The rising edge of the pulse turns the coils on, and is the start of "dwell
time".

In theory, we could trigger from the rising edge, and delay from that. The
dwell time is generally fixed at something like 3msec. Dwell time at idle
is usually more, since the idle fluctuates, and it might cut short the dwell
for the next spark.

Assuming fixed dwell time of 3msec, triggering on the rising edge, and
inserting a 3msec delay, would result in stock timing. Inserting a smaller
delay would result in "advance". How much advance would depend on the RPM.

Note that as the RPM increases, the time that it takes the crank to turn 10°
decreases.

So it is possible, just not with this unit.

Thanks for the interest in our system.

is it possible to delude the crank sensor in moving his target,or other "non electronic" way,because i hav'nt a programmable ecu

John Banks,

Is the version you got ,just a standard 1/2ch?

or is there made any changes to it,as i can see that J&S make changes as the custumer likes.

Thanks,
Skassa

john banks

Just a standard 1/2 channel unit.

I cannot see the need to be able to advance the ignition really with the vast majority of modifications.

Thanks John,

I would just like the J&S to retard,when it´s needed,and like you drive with the best map possible.


Thanks

Showing an Interest David but with MOT this month and insurance next not sure if I can afford it.

Cheers

as you know,the ignition map is the same for kuala lumpour,45°C 89 RON than great britain -10°C 99 RON ,so with the small TD04 ( yes i have,not for long time,but still now ) there is a very important improvment to add advance

David_Wallis

group buy discount. 20% off list, minimum ten systems,
order cutoff on 2/15/04

nom

Can we have a go at a list, then?

I think most are interested in the '1004-1CH/2CH' normally at $495.00, so the reduced price would be $396, I think... that would be before all & any of the various charges

And I think the list so far of 'interested' - although obviously not confirmed at this point, is:

1) David Wallis
2) P20SPD
3) Pavlo (4 channel)
4) Andy F
5) Beryllium
6) jlanng
7) Denmark
8) Rroberto
9) s672
10) Nom [confirmed]
11) Mr J
12) Tweenierob
13) CataIunya
14) Delboy2 (4 channel)
15) RSVR Racer
16) colin C
17) Jolly Green Monster

It might be handy if everyone could confirm/remove themselves as needed?
Probably also what they are after, the options seem to be growing...

Have J&S specified how this will work? As in, the orders need to be as a lump, or we all contact them seperately, they just want there to be a minimum of 10?

Sorry if I'm confusing things here, but I'm trying to help - honest!

p20spd was a 'possible'

Im only interested if the J&S will work with my ECU and MSD..

Im awaiting confirmation from Autronic.. J&S have been very helpfull though.

David

nom

Yep David, noticed the 'possible', just thought I'd list him so he could be 'unlisted' rather than forgotten.
Not that such a thing could happen, of course

Why would the Autronics have problems?
And, erm, what's a MSD? Or am I being an utter thicky here (for a change )

David_Wallis

it might be a problem because the autronic ecu doesnt control dwell.

MSD ignition.. http://www.msdignition.com/1dis.htm

I use the MSD-DIS2 race version

Nom,

Multiple Spark Discharge.. lots of sparks rather than one..

My understanding anyway, gives a better burn, less chance of blow out of the spark, etc..

Used a lot in US race cars and other applications.. (Like Wallis's Wagon )

Hm, something like:

"Of course you can use individual cylinder knock control, but only if you buy our model XYZ which isn't released. If you use the J&S product we will b very upsaid and tell everyone not to help you."

Paul

David_Wallis

not kidding

John at J&S

Hi to all.

David: If you are running waste spark with Autronic and MSD, you will need the 2 channel variant of our 2/3/4 channel unit.

It will be configured for non inverting operation, and trigger on the rising edge of the Autronic's ignition output.

The unit will pass the Autronic's output signal to the MSD.
