Log set

Post by 434josh »

Hey guys,

Attached is a log set of my ms3pro. Its my first megasquirt build so be gentile.
Everything seems to be functioning. Injectors fire in test mode, coils are firing, etc. Motor tries to fire then dies.

Setup is-
sbf 363 single turbo on e85
bosch 210 lb injectors at 43 psi
ls coils
36-1 crank wheel with sensor 40* from tdc
diy red threaded body hall sensor at 12v plus 2.4k pullup
explorer single tooth vr cam sync

If i key on/off twice it lights off but immediately dies. Trying again without a new prime it just rolls over with occasional tries. I have added and taken out a ton of cranking fuel. I have tried rising and falling edge on both sensors. Rising on crank and falling on cam seem best.

Any help is appreciated. I saw data on the tooth log but nothing on the composite or sync but I hope its just the noob effect.

Well it appears none of the logs kept any data. Very strange. The tooth logger showed in tuner studio but megalog viewer is showing nothing...

I will try again tomorrow.

Two of the logs did not get anything. A fairly common cause of no data is a low battery and the ECU is doing a reset as you attempt to crank the motor.

Your missing tooth is in a bad place.
