I tuned the A/F in the 3rd gear and it is good at 13. but in the 1st gear from 2k up to 5.5k it is around 11 a/f but then at 5.5 it goes to around 13 a/f and takes off. I can't gear comp it to take out fuel because I am going to lean cut since it will also rase the a/f at 5.5k when it is at 13. So is there any way to just tune the a/f in 1st for 2k to 5.5k ?.

I have a K20a3 rsx with CAI/DCRH/E 310 cc and a PRB IM. the ecu I have is a PRB type s ecu with kpro
I have attached my datalogs and my kal if anyone wants to look at what I am talking about

Try changing your lean protection trigger time to 500ms

Or just disable lean protection.

Why not just pull some fuel out of the tables where the AFR is ~11.4:1? It would probably help to lock in the cam to 30, 40, 50 degrees, make a run with each and tune each individually, then switch back to the cam map you have now and see how it runs.

Don't forget to follow the VTEC table when it is active (ie tuning on the low speed cam when it is active and the high speed cam when VTEC is on). Alternately check Options > Tables follow cam angle and Tables follow VTEC to make sure you are looking at the right ones
