That will happen if the base timing is very low. I've set base timing to -10 on turbo cars that still ran TFI or EDIS so that they could use anti-lag, those won't idle with the spout disconnected.

Lamrith, let me know if you need some help, I think I can help you. I got my car to run and I am able to tune it now, I will post what I found out so far.Duly noted
Does that go for the MSPnP Gen2 94/95 setups as well? Or should I get it close and then use the trigger wizard offset to adjust for any difference?You wont get any spark with the spout unplugged. You lock the timing in TS and set the offset to 10*
Then adjust the distributor until you get you locked timing value
I appreciate that, and will hold you to it. I have a thread over on the MS group on FB and they actually pointed me here to look for "A91What" then I found this thread.Lamrith, let me know if you need some help, I think I can help you.

I had my MS set to fixed 10* and it happened to have 11 offset in it. Opened trigger wizard and while cranking the target on wizard was 12, but balancer read 18. What would be your recommendation at this point, should I move distributor to bring it to match the wizard target value, or adjust the wizard to match the balancer reading?

Spout out for me was not an issue that timing is so far off it will not run. When I pulled spout with MSPnP Gen2 installed in my 1994 there was no spark at all. I thought my timing light was dead as I got nothing at all from it. Put SPOUT back in and off it went.
I am not sure what all my root issues are. I had timing problem and hoping getting that dialed from this thread and the FB group will get her running. But I am also seeing signs that my injectors may possibly be bad/leaking as the rail is not holding pressure. I expect pressure to drop over time, but I can see it dropping as I watch. Could be regulator as well, but the reg was working on my other car just fine. This is a brand new built 393 motor, so I am desperate to get it to fire and run on it's own to get rings set and basic breakin done. fingers crossed that will happen tonight!

I have the same Megasquirt ECM you have, if you have the ignition settings set correctly, you should get spark with the SPOUT out. I can post a video on YouTube to prove it if you like.
That seems to be the least of your worries, did you upgrade the fuel pump to a higher volume when you upgraded your injectors??
Yes it's the same. All Megasquirts operate the same way. Both of these techniques will work.Does that go for the MSPnP Gen2 94/95 setups as well? Or should I get it close and then use the trigger wizard offset to adjust for any difference?

Then something is wrong. Set up correctly the TFI system will spark with the spout out. Captainwesome81 discovered the cause of his same symptom was an incorrect setting for Cam Input. I didn't know that could cause it so thanks to him for running that down. That may or may not be your problem, but I'll repeat no spark with the spout out is not normal. If it isn't the same problem as CA81 then it's something else.I appreciate that, and will hold you to it.

Yes it's the same. All Megasquirts operate the same way. Both of these techniques will work.
That said you can't set a timing that is less than your offset with Ford TFI or EDIS because these systems automatically spark at the offset.
Sure I can write it up tomorrow. I'm just on my phone tonight.
An offset of 56 is interesting. Can you take a picture of your distributor cap with the #1 plug wire marked? I'm betting they're one position off standard, which is 45 degrees, and then you effectively have 11 degrees physical advance, totaling to 56. This would mean the minimum timing you can achieve is 11 BTDC if my guess is right.
I was thinking the same thing about the fuel pump, that is why I asked him if he upgraded the pump when he went to larger injectors, and a larger engine.Yes it's the same. All Megasquirts operate the same way. Both of these techniques will work.

For the same reason you can't use spark cut for rev limiting, you must use fuel cut. You also need to consider your base timing for anything like traction control or soft limiters. If you configure a subtraction that would bring you below your offset, the spark will occur at the offset timing.

I've seen fuel pumps that bleed off pressure too. Disable priming pulse if you haven't already or you'll get a squirt every time the key is cycled.
Please explain. The trigger wizard offset and whole timing thing for megasquirt has always confused the hell out of me.
I have my offset at 56.....the little help tips say that a setting of 10-19 OR 50-80 is acceptable
Thanks for the explaination seijirou.......I forgot to snap a pic today like you requested, but i had an older one on file.......
That's the correct position. I realized today that my thought about +45 is wrong for a couple reasons. Can you post your MSQ? Not for any other reason than my own curiosity.
In your megasquirt timing video you had said you used PIP to disable your car? That made me think it was a normal thing and part of how the system worked, has that changed?Bottom Line is the TFI system should work independently of the MS. Many people have documented the no spark condition with the spout removed, this is something that needs to be resolved on a case by case basis. No matter how the settings in TS are setup the TFI should fire without the spout and the pip signal should still come into the ecu.
How to tell if the pip may be failing from a datalog; when you are watching a datalog during decel the rpm input may become erratic. typically this is an indicator that the pip is failing, this also causes bucking issues at times. decreasing the rpm lag factor can help alleviate this issue
Can you post your MSQ? Not for any other reason than my own curiosity.
Yes i did, I replaced everything and did quite a bit of testing. In the end the MS would stop functioning with the spout removed. I always assumed it was the DIYPNP, I have since always used a 36-1 wheel and coilpacksIn your megasquirt timing video you had said you used PIP to disable your car? That made me think it was a normal thing and part of how the system worked, has that changed?
I would hope my PIP is not bad as I have a brand new distributor I purchased for this project. At this point I cannot get the car started to check anything. but given my timing issues I hope to change that tonight once I correct my errors.
