I have ajdm only 1998 Mitsubishi legnum st with a4g93gdi. Wired the det3 based on instructions.
Analog1 clt temp
Analog2 built in map
Analog 3 gm iat sensor
Analog 4 innovate lc2 wbo sensor
Stock maf is frequency based so it’s wired to frequency in and pull-up.
Ignition is hooked up to ign in with pull-up
Frequency out to stock ecm
Ignition out to stock ecm
Power and ground are direct to battery with switch and relay
All that said I’m getting a maf code even running in passthrough mode(no corrections) to either maf or ign
Frequency setup is 25-2200hz base unit 1 and multiplier 1 in either linear modify or non linear modify
Fuel table is setup as
Frequency
Frequency
Disabled
Disabled
Stock narrowband still intact, could use innovate to emulate it if necessary
With this I’m getting a maf code, logging shows freq in and out match each other. Any help with this would be appreciated. Thank you
