check grounds on the car... engine, and main ground straps. check the charge wire from the alternator to the fusebox, and replace with an 8 to 6 Ga wire if it looks corroded or has resistance... I have had to replace many of them up to this point.

I used my digital volt meter car idles at 14V Ectune reports wrong voltage

Power and ground the wideband somewhere else. I know on the innovate LC stuff the heater power and ground can induce noise into whatever you wire it to, so wiring it directly to the ECU ground or power is not a good idea.

Ok So i disconnected LC1 completely Did a datalog, battery voltage stays constant 13.6-14.2V

Now just need to figure out how to wire this LC1 Blue and Black Wire are tied together to a chassis bolt. Hope this is ok I will Connect Red Power to a FUSE 12V in the Fuse Box. I will connect White ground to Battery Ground. What do you guys think?

Wired Lc1 into the fuse box Wrapped Red Wire arround a Fuse Leg, Put it in a 12V Source White goes on thermostat bold/ground blue and black wired together to chassis. Idle Offset is more or less in the 14V Table But Afr ay 750rpms go like 14.3-14.5-14.7 and cycle. I dont think thats right. What else is there to check

The LC-1 has a lightning fast response time... meaning; if you look at a log from logworks, and zoom in, you can see the drop in AFR between the pockets of exhaust from the individual cylinders... it could be that happening just now and then... or... the RPM's are not holding exactly at what RPM your measuring at and that could be the cause for different AFR readings...

I will post my Log and Map Please let me know if everything looks okay

Ok Update Cleaned grounds and paint on chassis. Battery Ground terminal was slack, Tightened it. Now Voltage Wot is like mid 13 Idle close to 14V Battery offset reads 14V Tables. Sounds okay?

don't try to get it perfect, it'll change constantly, just get it close within reason and go with it.. you will never get it perfect.

Do you mean the AFR or Voltage?

AFR..

great thanks so sometimes it will idle 14.7, then 14.4? is that normal?

yep, sounda like you got it licked. just because the ECU only sees 13V, doesn't mean there is 13V at the battery =P

no i meant AFR not volts
