Ignition divide = 2 and no of cylinders = 4. You will need a basic timing and fuel map too and calibrate sensors too. That trigger angle of 70 seem a bit high, bring it down to around 54 - 57 degrees
Selecting the "Reset map in ECU" button will load a default map into Dicktator. Be sure to first save your current map BEFORE loading this default map in. There after you can change the distributor option to wasted spark. The default ignition map is starting off a bit high and you can bring the 10 degree values down to around 5 or 6 degrees. Bring down the whole map a few degrees if it is pinging. Fuel page should be rich and ok with default values and then you can start trimming them down in small increments to prevent over fuelling.
Considering that the 60-2 gap on th motor sits at 90 degrees ahead of tdc i think the initial 70 degrees should be ok. 50-57 will be making for very fast timing.

Morning all, thanks again for the advise and help. The engine fired up for a second or 2 on Saturday on a bit of quick start as I have not connected up the fuel pump and the tank is dry. I want to get a fire extinguisher before I have fuel present. It did POP and small flames shot out the intake as it fired up. I don’t know if its popping like that coz of the timing or the high octane quick start fluid.

You're correct panic. 20v motor sits at 90 degrees.
Hi all, so I hooked the fuel pump up and put fuel in. The engine pops and splats but doesn’t take properly. After a few swings nothing happens, checked the plugs and they were wet with fuel. Does anyone have suggestions on what I can check or try next? When I put the key on, dicktator comes on fine, fuel pump runs, dicktator relay clicks and the throttle body clicks and makes a constant humming noise (very soft)
Check for decent spark, reduce the fuelling, make sure the firing pairs are correct. Try again.
This is pretty much trial and error, not just jump in and off it goes.

Agree with Panic.
Check the firing order of you plug pairs. If popping happens it could be that the spark fires during open intake valve.
Hi all. So I was working on the car tonight and decided to check firing. I took the coils and plugs out, earthed them and started swinging. Cyl 1&4 fires then 2&3 as per my slow mo cam. Now I'm no mechanic but shouldn't it fire 1342? Coz if 1&4 fire at exactly the same time cyl1 will have fuel and cyl4 will have exhaust gas? I know I'm prob not qualified to do this but I want to learn and do it all myself. Any comments?
they are correctly wired - they are supposed to be in pairs 1,4 and 2,3
It's called wasted spark. So the issue you might have is that the wrong pair fires first. So just swop the pairs first.
So go thinking nicely about the 1,4,3,2 thing and the pairs.
so when 1 is on power stroke and fires it does 4 at the same time which is in exhuast so it wastes that spark - hence wasted spark.

So I swapped the coil wires and it back fired out the exhaust once and then out the intake again. The only difference now is it almost stops dead when swinging. It's like it fires as the piston is coming up and stops the engine so I immediately stop swinging. I really don't want to take the car to a shop but it's heading that way. Any dicktator guru's in Cape Town that can come to me perhaps?
Ok then you had the pairs correct. If you then change it back and still have it backfiring either you have the timing way too slow or way too fast.
Try shooting the timing with a light, and yes you can all you need to do is place the inductive pickup on top of the coil or pull it out the gead, put a plug on the coil and clamp the inductive pickup around the spark plug.
That way you can see if you are close with timing values. You want to shoot what your computer says the timing is when you crank. That way you know if your refence angle is correct.
Have you tried more fuel / less fuel?

I will put back the coil wiring as before, I can get a friend to come check with a timing light as i am not so clued up with that. I put the fuel down to 1.2 ms as suggested. I tried the trigger angle at 70, 60 and 50. I Put the ignition at 6 and tried 7.
I know a guy that knows a guy that installs dicktator and other systems at a dyno shop in CPT, spoke to him this morning and he says I should try swapping the 2 inputs around at the module.
Uhm, that is exactly the same thing I made you try. Ie that will swop which pair is firing....
Or what did you swop around? You didn't try putting 1,3 and 2,4 together?
It has to be always paired 1,4 and 2,3 and then you swop the pair over on the driver.
It's so hard to do this stuff remotely.

No I never changed the pairs. I always kept it 1.4 and 2.3
But I swapped the 4 trigger wires at the module. I always check the spark before firing for real and it always fires outers then inners in pairs. So 1.4 then 2.3
I know it's difficult to fix just by text but thanks for the advice so far.
Ok that is great then. So yes then basically you did already what the guy that knows a guy is suggesting .
His way is just different. So you swopping the out or him suggesting you swop the in has the same result.

True, i just think its firing too early or too late, could my air and water temp sensors be a problem coz i dont have those 2 hooked up, or the boost pressure pipe. In my understanding it should still fire up regardless.
You probably stay 100m from me, send me your cell number in a PM and I'll bring over my digital timing light/lambda sensor/laptop etc etc and we can get it sorted.
