Hi all
im new to the forum and have started a microsquirt upgrade on my crossflow engine powered Locost but have no idea where to start when it comes to tuning i have a wideband but need a base map or an idea of where to start with my own map.
any help greatly appreciated
Regards
Mark

I don't have a base map but I can get you started on making your own. First question: What's it running for ignition control?

thanks

All right, if this is a V2.0 Microsquirt, you'll need to configure it for logic level output, and use these settings for the ignition.
Trigger angle: 10 (and adjust as needed)
Ignition input capture: Rising Edge
Coil charging: EDIS
Spark output: Going High / Inverted
From then on, it's mostly a matter of following the tuning guide:

im doing a semilar setup with ford edis 8 + microsquirt
so far i got the system get VR sensor signal (170 to 250 cranking speed on tuner studio)
im getting sparks from from coil wires on spark plug tester
injector harness is giving me around .23 to .65 volts on the voltmeter ...is this correct ?
is injector characteristics important enough to prevent engine start ?
do i have to set it to high impedance or is already set that way ?
please help

The MicroSquirt injector drivers are set up for high impedance injectors already; they do not do PWM current limiting.
A volt meter generally isn't fast enough to see what the injector outputs are really doing.
