No injector pulse during cranking

[gboezio]

I have been trying all day to get injection pulse during cranking, the pump is coming on, I stabilized the RPM, I have spark, fixed leaks, not a bad day at all, but I can't get cranking pulses width to get off zero, I get a prime pulse when I power up the unit, but while cranking nothing, it cranks around 200 RPM, the ECU say cranking, but both injection channel stays dead.
The computer is in the garage, I'll try to get a video and a copy of my MSQ file.
Any help will be appreciated, it's almost alive, so close it hurts.

I used the injector test mode without fuel pump, I can hear them opening and closing loudly, after the test, small amount of fuel blew in the exhaust. So uS is able to trigger the injectors, but won't do it.
I may try to update the embedded code, maybe a mismatch is doing this.

[gboezio]

OK I updated the embedded code to 2.890 and the INI file to 2.890, but Megatune won't allow me to change the crank wheel teeth number, as soon as I go back it says 0, I tried to revert to an older version so I re installed MT, same thing, yesterday it was working fine.
I do hit the burn button, cycle the power of the unit, but as soon as I close the advanced ignition window it replace my 12 teeths by 0.
I definitely need help on this one.

Edit : I made a new MSQ from scratch, it will stay programmed like I want until I turn on the power of MS, then the tooth number will change to 0 and will not come back. Even if I did not burn the values or if I do. I guess the new code is having conflict with MT

Ok it's the new code, before I could use EDIS spark output and I had spark, now if I choose EDIS, my tooth wheel count will be erased to 0, like if I could not use a tooth wheel, I'm using uS in logic level trough the bike stock ignition box, (not computer) with the normal coil output set, I have no spark but I'm able to set 12 tooths and get mt RPM back and injection pulses, but no spark of course.
I think it's over my head now.

There is nothing wrong with the code. Someone just had the problem of no. teeth would not burn and I think and they reloaded and it went away. (Or it might have been that they had rpm running (from engine or stim) when they did the burn or you didn't hit the tab button after you entered no. teeth).

As far as edis - you can NOT have any teeth with edis because edis means 36 teeth and you get your tach pulses from edis, so the processor does not care about no. teeth and because it messes up the code to have edis + no. teeth > 0 (because it doesn't know which mode to follow) no. teeth is automatically set to 0 if you choose edis. This last change was in recent code, but it is necessary. Older code would not work properly with edis + no. teeth > 0. The new code makes this obvious.

I have never seen any code that won't operate the injectors unless you have them configured wrong (for example too short a pw or bad pwm settings) or you have no rpm. The other possibility is something wrong with the wiring, but this is unlikely since you are able to operate them in test mode. What pw does the MT gauge give you ?

Thanks for the reply, I was so desperate, I had zero PW except for the priming pulse, then nothing, but since I updated both code and ini file, I get the pulses working right and it smells like it. My guess is that the embedded code and MT were not matching and it created a conflict or it was the EDIS thing or another mistake.
But when I choose the normal coil charging option I'm loosing spark totally.
I moved the jumper in uS and I'm trying to figure out what setting is the good one to drive a smart (I think) ignition system, The EDIS makes good clean sparks when it was working on the older version, maybe not at the right time, so I thought that it was the correct setting for the logic level, I think that if I could get the standard coil setting to fire a square wave, I could probably get it started, the coil fire when the power is shut down.
So it explains why it won't stay set to 12 with the new code, I was definitely hitting tab, loaded and reloaded, booted and rebooted any way I could imagine, but it seem to be a mistake from me.
Other than that this is fantastic, it was so easy to set up and wire, everything worked right away, if I haven't ran into this snag it would have been a matter of a single week end

The question remains, how could I set up to trigger my coils ?? I have looked around to find the place where I have read about the jumper, thinking that maybe some information on the correct setting was there as well, but I can't find it back.
Here's a partial picture of the wiring diagram, I used the Black/Blue and Black/Yellow wires to the two ignition outputs

I'm not sure what is going on here. Are you using EDIS or not ? If there is another ignition module, as shown in the figure, are you using it to control spark and just taking the tach signal from it ? You can't have both microsquirt and the ignition module controlling the coils. If you are using the converter wires to control the coils, are they disconnected from the ignition controller ? If so then you have a standard toothed wheel setup where you are controlling logic level individual coils, and the ignition controller can be taken out of the picture. If that is the case, post the msq you are currently using. Also, do you have specs on what is needed to control the converter unit in the diagram, or can you just use the microsquirt VB921/ Bosch ignition drivers and bypass the converter unit.

I'm not using EDIS, it's the stock ignition module that was controlling the coils, the ignition computer is disconnected and I get my tach from the 12-3 toothed wheel and VR snesor that was used originally.
I wired the plugs and selected, normal coils...no spark, EDIS clean blue spark, EDIS multispark ..no spark, so it was obvious to me that the correct choice was EDIS...or not

Correct, I moved the jumper to the logic position, and wired the ignition outputs to the two inputs of the converter unit. I'm getting good clean spark when I could run EDIS setting and 12-3 tooths setting on the older code, the unit throw really nice blue sparks, but I had no PW back then so I updated the code and now get the pulses going, but since the code wont allow my franken-EDIS setting, I lost my spark.
When I select driving coils it will spark once, i usually get a spark when I shut off the power (I need to confirm this)
I'm thinking of selecting the regular coil driving option and increase the dwell until I get spark.
I have found this morning some code modifications to increase the dwell to 25, I may try this to see how it works.
I don't have the specs of the Honda converter unit.

The MSQ I'm using is posted on the first posts, this is the one that got me no PW using the firmware that came with the unit.
I will be away from home until friday, but I have internet here, but not my files.
Thanks again for help, I'm taking any suggestions as gold lol.

The code was not meant to run in edis mode with a 12 tooth wheel. Your best bet is to leave the current configuration and try to get spark working. Your configuration seems reasonable, so I would look at whether you have ignition outputs. I would scope the ignition outputs at the (disconnected) coils (or make led ignition testers as shown in the megamanual, or test the configuration on the stim and look at the ignition lights). (I would disconnect the injectors to avoid dumping fuel in the cylinders.) If you don't see any outputs, but you have rpm then I will test your msq on the bench. If you do see outputs, then you need to find how the coils are triggered. It may be you need to reverse polarity of the outputs. If that is ok, then it may be your timing is way off, so reconnect the coils and check timing. Switch to calculated mode when doing this so you can use trigger offset to make the timing match your timing light. Then you can go back to trigger rise.
