....I'm working with Guy on providing kits in the UK. Somewhat of a backlog at the moment, but ordering PCBs 20 at a time from Brent. You can get everything from Maplin if you do a bit of digging to Xref things. The Price list we are working to at the moment is MJlJr kit of parts £35 (less case &am...

Brent,

What type of output is the MJLJ giving that drives the Runtime Display?

I'm thinking of a way to capture this output to be able to later analyse it to see what the MJLJ was doing.

Does it need to be a Java based utility?


Thanks,

Nick.

Yes.

Do a search on TPS. There's a description somewhere of what you need to do.


Nick.

Kitt,

I don't know if it requires sheiling, but I had some shielded cable and thought it better to use that than introduce any problems by not shielding.

The ground runs from the ground connector on the TPS to the ground connector on the Molex which then runs to car chassis.


Nick.

Yes, drives my tacho OK. I couldn't get my tacho working properly with the diode circuit.


Nick.

edowner,

I had a play with this a while ago too, just got back to it again.

Looks like mjlmTune uses Swing which Jeode does not support...;-(

Brent, any way around this?


Nick

The tacho out drives the tacho in my car no probs, you get an nice clean square wave signal. The only reason you might want to use the diode circuit is if you have a rev limiter for example. I tried to get the diode circuit to drive my tacho and rev limiter, but it didn't work for me, although other...

Can I have a copy too please?

Thanks,

Brent,

My PC is changing the .jar into a .zip for some unknown reason (probably something to do with WinXP SP2 I've resently loaded!!!)

I just renamed the .zip to a .jar and it works OK.


Sorry,


Nick.

Yup, thats basically what to do.

Then you just put the same values in for at MAP/TPS points, so it gives a 2D map.

Moving on from there really needs a rolling road unless you have a map from a similar engine or REALLy know what your doing.


Nick.

Brent,

The link I'm clicking on says it is for:

http://picasso.org/mjlj/dist/mjljTune-2.0.3.jar

But the file that is actually downloaded is:

http://picasso.org/mjlj/dist/mjljTune-2.0.3.zip


BTW, what the hell are you doing up at 06:00 in the morning...


Thanks,

Nick.

I created a map that was basically a copy of what my dizzy would have been providing. If you use this as a starting point then nothing should go bang...
I think the best way forward from there is a rolling road session.



Nick.

Brent,

Can't get the .jar file for the config software.


Nick.

Ivan, To wire in a TPS you need to mod the board slightly. Get some fine single core insulated wire and run this from the N/C pin of the X2 connector to the hole in the circuit board where the Output pin of the MAP sensor should be (don't install the MAP sensor). The Output connection is the one tha...

Hello, There is a very good and reliable UK source for either Megajolt components or completed boards or units, so you don't have to have the hassle of getting stuff from the States. If you intend to use TPS then they can mod the board for this aswell. (TPS works fine, I'm using it already) You can ...
