AFR reading not correct in megatune
 

Hey guys as the title states, Iv searched and basically came up with its a problem with grounds, (running mspnp on 1.6) I had it all set-up and working for a while now but now it wont work.

I'm wondering where the grounds go from the ecu so i can rewire them to see if they are broken or something somewhere.

LC-1?


can you connect to it with LMworks directly?

yes sorry lc-1, I connected all the ecu and wideband grounds to one lug on the engine like the directions say and still no difference, when the gauge is reading high 10's the gauge in megatune is at 4.364 moving up and down a bit.

Check what the lc-1 is outputting, the output should be the same as what you have TS or MT set to see. If not you can change what megasquirt expects, or you can program the lc-1 to output what megasquirt is expecting. I had a similar problem awhile ago. Its now only around .1 afr off or so, if that.
