Hm. What exactly is kickback? I advanced timing for the stock injectors, but the mustang injectors didn't really like starting up today. I have to play with a few things, but I wonder if they just don't like the timing.

I understand this.. I just must have missed a number or something when I punched it into the calculator. The only thing I'm not sure of is if Cranking PW needs to change after req fuel is changed due to Injectors being upgraded.

While cranking, it's basically detonation, except at cranking RPM the detonation has enough power to stop the crank or even knock it in the opposite direction which I don't assume is super great on my starter

this could be fault of a lot of things... too much fuel during cranking can do this, spark outputs being incorrect can do it, etc.
I took a datalog of it but I cant upload it right now because my school turned their WiFi off. Will upload it ASAP along with my tune or at least the one I have saved and revert back to. Thinking about just pulling the MS and putting the stock ECU back until I figure out wtf I'm doing :( |
kickback is not normal, have you had it since initial install, or since changes hundreds of settings?
the cranking advance is not your key to victory here -- i think my maps have it something like 18°, not sure why you keep retarding it. |

Does the car start in flood clear mode? I.e. with the throttle pressed all the way down at startup?
And just to confirm, it had no issues starting up on the stock ECU right? Can you post a log of the behavior and your current tune? |

Is your tune currently brain's basemap on your ecu or your basemap modified using brain's map as a guide?

Ok.... so something is definitely wrong. The car started up and was acting like it was running on... less than normal cylinders. I have it on video and will upload it if needed. It smoothed out (a little) after idling for 15 seconds or so. Pulled out and took it easy just to warm it up than once it was warmed up I started getting on the throttle a bit more. The exhaust note was still not the consistent hum it usually is. Close, but not normal. It was kind of rumbly, almost like subaru style, as if it was on 3.. wtf. So I came back to the house, power cycled, and this start seemed better. Took it out for a drive and it was back to normal...WTF!! This has not the first time this happened. The thrid time actually. One one of the first couple days I installed the megasquirt I had a similar experience, except much worse. This time the difference in sound/power was somewhat noticeable but if I wasn't listening for it I wouldn't have noticed, but the first and second time this happened, it was DEFINITE. Sounded exactly like this (NOT MY CAR) https
Something about my car/MS is definitely not normal. Datalogs and tune included. One running on almost three, the other running normally, or at least as normal as it has on the MS. |
Just a wild guess,
your cranking is set at 500. Your cranking in real life is somewhere around 190..... see if the cranking rpm will make a difference. Although muine is a NA I have an NB starter motor. Mine is set at 220 set yours at 250 or 300? |

Just saw your above post....I somehow missed this was for a Toyota.
I didn;t realise you had started it. My apologies |

Other things Ive noticed. I hope you don't mind.
In the fuel calculation , you've set the required fuel to 11.2 ms. thats fine. would it make a difference if you actually filled out all the the proper settings. like fuel flow of your injectors & correct engine size? In your trigger angle offset you are running -2.00 I have fastly different settings, but my CAS is set dead on 10 deg BFDC. and trigger offset is like 13 deg. In my case I have some long duration cams.which would make some difference I know this is exactly what youve been talking about.....but thats really odd. |
In Idle control,
\your valve mode is inverted. rather than normal. But your valve settings are standard closed at 32.9 open at 61.9 so the valve is working i reverse or that's how I understand it I might be talking shit......hopefully not. Thats just what I noticed |
