Finally got my brainy MS2 installed and even starting. Runs rough at 1-1.2k rpm (untouched and untuned, so OK for now) and get funky O2 readings all over the place. See log. Car initially wants to die with any throttle input, but after a small dip rpms do rise, yet roughly.

Is this a dieing LC-1 or would a calibration session be in order?


2nd question: the knock settings are far more advanced over MS1, how to set it up? Knock indicated by input low/high? Pullup/down on input? Using a knocksenseMS unit that has been working fine since installing a year ago.

Enough stupid questions for the day.

Current tune and a small log showing funky AFR attached.

 

When my WB was giving me bullshit readings, a new sensor fixed my problem.
I'd check all the wiring/grounds, then calibrate. If its still screwed, I'd replace it.

 

I'm having similar problems with 1-2k throttle input and accel issues. stumbles initially then starts to accel ok

 

If you need a new sensor for your LC1, here's how to get one for $32:

I'm pretty sure that shipping will negate any discount tho

I might get some **** done tomorrow, weather allowing. Recalibrate the damn thing and log simultaneously on TS and logworks. If that doesn't work I'm setting it on fire and be done with it.

 

Have you tried adding a little fuel? Where's the wideband grounded?
