Need help idle goes crazy once warmed up in closed loop

[Sean13]

Hello everyone,
So once my GN warms up and goes into closed loop my car starts going super lean then normal back and forth afr gauge goes to 20 then back down to 14.7-15.2 some times it dies scanmaster numbers are all in range where they should be as this happens I did a smoke test to try and find vacuum leak but nothing 5.7 chip from turbo tweak can someone point me in a direction to go thanks

The best thing to do is warm engine and post Scanmaster readings
Also give some info of year and any mods

[SCOOBY DOO]

You're running 5.7...it reads off the narrow band.

 

[SCOOBY DOO]

Are your BLM's staying steady at idle warmed up in Park?

 

[Chuck Leeper]

[Sean13]

[SCOOBY DOO]

Will do and changing 02 pricing one up now thanks for the help I will let u know

 

[SCOOBY DOO]

I'll assume this chip is burned for your EXACT combination...and I'll assume you have the Translator set correctly.

[Sean13]

It is burned for my set up and I set map translator up how it should be

 

[SCOOBY DOO]

If you change anything like injectors, heads, turbo etc then the chip has to be reburned.

 

[Sean13]

Yes sir I spoke with Eric about my combo and he burned chip for me and talked me thru install

 

[John Larkin]

Get Denso O2, not Bosch.
