i have the same problem as u SLVR

the logs is showing higher load (260) than it should be if checked using RPM & Ignition to look up the load on the original car map
My boost is spiking max 22 psi and then go down to 19 psi.

me also have the K&N induction Kit and a cat-back HKS exhaust with De-cat pipe.

i was suspecting my load calculations and actually find some thing wrong with it.

my injector scaling = 542 (EVO VII JDM)
and latency calculation should be

inj_latency = (-0.1026*battery)+1.9226

after correcting the calculation, load calculation were closer to the correct but still not ok

if the formulas is 100% correct, then the AFR-MAP reading ihas something wrong.

 

get you car tuned for the alky then pull some logs, i don't think its good for your car to be running alky without a tune.

 

Whith alky untuned your probably in the 9:1 A:F, I was. Post that log in a correct format and put car on dyno with WB to stabilize your A:F

 

i tuned my afrs to 11.5 and still hitting the same load.......... any suggestions? i might try swapping my friends stock airbox on and see if that makes a difference....

 

just wanted to update this thread.....i scaled my maf and now im only hitting 311 load at its max.....so i guess thats much better that 360....
