i have a 97 d16y8 obd-2, got a check engine light in 4th gear at 6k, and when ive been driving it lately its been loosing high end power

greddy kit
turbo xs boost controller
aem cam gear
255 pump
450cc inj
vafc hack

i jumped the code and it blinked 3 times over and over again

30 SEAF/SEFA/TMA/TMB signal line failure.

what is your v-afc hack settings? Also, how much boost are you running?

[tyrant]

sensors 6/6, v/t mmgt 4/4, -40 to -35 for fuel map

i put a check valve just to see what it does and the car runs good with the check valve which tells me that the vafc is not controlling the map sensor fully or the map sensor is fucked
