I think it can be done - here is the top view of the engine. The top pulley just runs the fan, so could slip with the fan belt, so no good there.


This is looking down at the crankshaft pulley. Plenty of room and I can probably get access by taking the front grill off. Can the sensor be attached to the chassis or is it best to be on the engine to avoid movement?


Another view showing distributor etc.

What a lovely little engine..... Coil will run on my ignition, distributor is fine too, 2 sparkevents in 1 crankshaft rotation, but with distributor you must stay in the window the rotor will give you, but this also will be fine, you just can't tune it for maximum fuel- effiency but that isn't a problem is it???


Yes the sensor must be attached to the engine, there needs to be a constant gap of about 0.75 to 1mm maximum 1.5mm.. I guess the engine will move much more then that.... Overall I'm very confident that it will work..... Probably without tuning......

You need to change the wire comming from the points going to the coil for my blue wire, the red to plus after ignition key and blak to mass... And at last the wire with the plug into the
sensor.. put 1 sparkplug out, put a chopstick or simular into the plughole and the find the highest point of the cilinder, the last bit needs a bit of guessing. Then turn your engine 45 degrees in the opposite direction of normal running 45 degrees is 1/8 revolution. I Always fold a square piece of paper over two edges, you then have 45 degrees, hold it in front of the pully and turn from one edge to another and you have 45 degrees, or divide your flywheel teeth by 8.... thats the point your sensor needs to be right above the pickup (10x10mm)

Here again a 1-2-Spark update; During my christmass holyday a have worked at the software on the chip. I've made (very) coldstart with a low rpm turning engine better and I've made some changes to make it better usable with a brown Visa coil. The maximum dwelltime of the coil is lowered to 65/1000 of a second, not that I have complains or disturbances but in my mind this should work better.....

Also I worked on the connection software between unit and pc so now you can use a wireless bluetooth connection also, it is starting to look like Formula 1 technics now and all this in your 2cv It is really cool to sit in your favorite chair in your livingroom and tweak your engine outside.....

b.t.w. theoreticly it is possible now to start your engine from a distance... just mentioning it...

I also programmed the use of an electric fuelpump.... when you switch on the ignition the fuelpump works for 8 seconds (by a relais) and then stops.As soon as you start the engine the pump starts running too and when the engine stops the fuelpump also stops after 2 seconds. so for an accident or when you forget the ignition this will help you a lot... (safety or emptying your battery)

This can also be used for lpg tanks aso, or logic coils like Harley has (Harley our Australien member) not as Harley coils....


Here's a link to a video, where my testcar is running on 4 logic coils and the connection to the laptop is wireless by bluetooth. You can observe the tempgauge (tempsensor on heat exanger) when doing a coldstart starting about 4 degrees C. So watch the tempgauge and the extra advance it gives....





Two other things to mention,
I hope this week the professionally designed pcb's are ready so really hope to have production up and running soon.....


The other thing is I'm still working on a solution for Visa engine's I've got the other senor-amplefyer up and running at last so I hope to run an Original Visa sensor or a substitution soon....

cheers Geo...

p.s if anyone is in the need for a 1-2-Spark please send me an email and we will figur out an instant solution.....

Hey geo

Glad you are making something really good even better!

I like the idea of remote starting and bluetooth but i assume id need another unit..??

Going to get a yellow harley coil at the end of the month......

Yellow coil is a good investment, runs perfecty on 1-2-spark, Mark Lewis is running a yellow coil for almost 2 years now on 1-2-spark....

Bluetooth is also possible, however it is better to have a new chip.... but you can quite easily change them if neccecary.........

Starting on distance...... hmm I was just mentioning the possibilities, some American cars have it. But you need to be sure the gearbox is in neutral otherwise ........ so you need to make a or some swithches and when it is save to start the engine theoreticly it can be done over bluetooth...... with 1-2-Spark.

YES

1-2-spark runs a Visa sensor...... I've just did a run on my testbench, with the new sensor-amplefyer it is possible to run 1-2-Spark with an original Visa sensor..........

So now I want some feedback from you. Last night I had a vision..... I'm going to make a blackbox for Visa. You just need to plug in the original connector of the Visa wiring-loom put in the sensor at 45 degrees (the lower sensor) and of you go..

The sensor will be protected for electrical spikes by my blackbox and al the electronic stuff inside, so the it should be fine to use the Original sensors.......

So then you have exacty the same as you have now, you can connect the pressurebox also.
This was 1 of the first things I've programmed.....

So do you like this idea..

So this will be the cheapest solution to run a Visa engine... witout the Original box...

Ofcourse if you like you can run a substitute sensor also, so if you don't like the Original sensor(s) this will be your choise.... This can be done afterwards no problem....

So do you like it????


p.s. you don;t need a computer for this solution, I'm thinking about some dipswitch to change advance tables....


Please give me feedback....

How much to upgrade??

Maybe pm is best

Hi geo,
love the idea of a plugin visa blackbox! that would make things easier for many visa people! but I would like to have the possibility to tune it, but i presume that that will be standard!

although I need to make a complete wiring loom because I sold my last car with everything installed. so for me it won't be a problem. and I think for most people who are able to fir an visaengine in any A-type a wiring loom won't be a problem.

isn't it possible to make some kind of adapter to fit into the original sensorposition to fit the new sensor (that is what I would like to have)

looking forward to having an A-type again, just to be able to run the 12-spark hopefully by the end of the week I'll have a car (dyane, I want to trade)

greetzzzzz

Hi Geo
Personally I think I would prefer the 1-2-spark with all the options rather than a "black box" to replace the Visa box. Main reason being running a supercharger and having the ability for retarding ignition under boost and infinite tuning of advance and retard of ignition. Also after catching up on your advances with 1-2-spark I would like the electric fuel pump option as well.
Obviously if all the above are in the black box then ok
Cheers
Boggy

Hey Boggy, okee you want this......




I can provide the sensor but you need to adapt it to an existing sensor housing yourself...

I will try both this weekend and then I will design a pcb layout for it... (with the same possebillities like the 1-2-Spark with VR sensor....

I think I will also make just a blackbox for Visa without much bla bla, just plug it in and run it... I think it will go for about 123,- Euro..... (thought about that..)
