Yes, we have power in the spark plugs (I only tested one and everything was ok)
Take all of them out and retry, I have a setup with paired injectors, heard the click of them and assume they were working and one was dead, once they are out ask someone to crank the car and you should see sparks on all of them, and fuel mist coming out of spark plug holes

Yes, we have gasoline, it reaches the TBI intake butterfly, but here we already have a problem... I was watching while another person started the car and my surprise was that as soon as I activated the starter, it released such an amount of gasoline that even splashed out of the intake throttle!!! Compared to the original ecu, the amount of gasoline it puts in is excessive!! I think that this should be able to be regulated, either by the duration of the injection pulse or by the number of pulses or both.
There are 4 settings you can touch for that
- The injector open time under Settings/Injector settings/minimum time... that's like the minimum time it has to open to start flowing, cb500 2014ish open in 1.5ms... refurbished injector for an old honda j30 took 7ms, you may want to decrease that a bit and keep trying until the amount is adequate
- On top of that basis you will add fuel according to the mapping according to what you define as the max used at Wide Open Throttle and load, you can modify that on Engine Constants > Calculate Required Fuel, try putting a small-er number, and try again
- Make smaller the fuel mapped on the Tunning > VE table and say for the cranking area of rpm, mark the fields and decrease them by 5 and try again
- Startup/Idle > Priming pulse, this is how much fuel is added to the engine on start before cranking to "prime" the engine and have it ready for start, the colder it is, the more fuel you want to add, try setting everything to zero to not add anything.

I checked with the gun if the car was ready and my surprise was (and I don't know if this is normal this way or not) that when I put the gun in and activated the starter, at no time did I see the mark of the pulley align with the mark on the engine block, what's more, at no time did the pulley mark appear. and I don't know why it is.
I can say that with the original ECU, when activating the starter, I can see the pulley signal.
So can someone help me again?
thank you
say you have a 36-1 pickup, when you are on top dead center of cylinder 1 depending if you are on rise or fall trigger you want that to align with the first teeth after the missing one.
if when you set your cylinder 1 and that's the one tied to the first spark plug and first injector is at top dead center (that's when the piston is all the way up) you are not on the first teeth then you need to update that on settings > Trigger setup > Trigger angle
If say your engine rotates clockwise (unless is an old honda with accessories belt on the driver side for amurica, that's the case) you count how many teeth from the missing one is the current teeth on the sensor and multiply that by 10 (for the 36 teeth), so if you are in the fourth teeth you should put 40 in the trigger angle degree.
another way is to start pointing the timing gun until it flashes on the mark and see how many degrees off you are and update the value...
and the absolutely worst approach... start adding 10, burn to controller and check again until you reach 360
