My LC-1 is reading 20+ F/R ratio when i am in gear but no gas is applied (no throttle). Other than that, it reads perfectly. I have it hooked up to my MSPNP. Anyone has the same problem?

 

It's the Over Run fuel cut settings under the Extended menu. Basically the ecu cuts fuel to your injectors below a certain KPA, the stock ECU does the same thing. You can turn it off; waste gas and not really notice any difference if it makes you feel better.

I'm pretty sure I bumped mine up a good bit (more aggressive) from the base map settings. Current settings are below 25kpa, less than 5% throttle position, and greater than 1500rpms and it drives like stock.

 

It's supposed to do that.

 

Great. thanks for the answers!

 

It's a fuel saving/emissions feature.

Turn it off for some nice burbly afterfires as you decelerate. I like to do that from time to time.
