my car is running 30 lb injectors.
The o2 doesn't really show most of the time guage is red then sometimes it will some a reading.
Car cranks then you have to tap the gas to getit started, when it starts.
Crank setting moves all over the place.
Upgraded to 29q. Map reads mostly 65-68 a few times it showed 190 while the MS was on but car not started.
When I was using 24 "the test config I found out" it ran and idled but still no O2 reading
Using an lm-1 set at default on output2 widebar

Thank you for your input

Not an expert by any means but, here are a few things that I noticed.

Are you running a boosted motor ie supercharger, turbo etc?? If not, then you need to change the setting in your VE tables to reflect a maximum of about 101 Kpa. This is altitude and MAP sensor dependent.

Secondly, make sure that you download the correct data chart for your O2 sensor and that it is identified correctly in Megatune.

Thirdly, check your wiring and settings. Just because it runs, doesn't mean it wired correctly... been there done that

Try richening up your VE and AFR tables by 10 to 15 % and see what where you need to go from there.

Post all your board, MSII or MSI, software and other stuff. Trust me it helps the real Guru's point you in the right direction.
