hello guys I have a bogging issue that may or not be related to not having a map sensor. I took a 95 ej22 in a dune buggy with a vw trans. Dont know why but for some reason Subaru made this obd2 my car bogs at around 3000 rpm like some one is cutting out the fuel so it sputters. it idles perfectly through high neutral revs and it drives wonderfully up to 3k rpm (while driving only) once it hits 3rd gear it bogs around 2500 not sure the mph. I can go at a higher rpm but it sputters its way up there though. I did not keep the MAP sensor a lot of the swaps said nothing about it so kinda unsure if i missed something on that i'm finally starting to get codes to pop up. I have p0105 which is for the map (didn't install with swap) could this be my reason i'm bogging. fuel pressure is perfect at idle but not sure when driving the guage is inline between the filter and block. I have the up stream o2 sensor installed but not the second (Assuming it monitors catalyst efficiency). the vehicle speed sensor was a pain too, i figured this was the original culprit? I have small cars hall effect sensor kit thats designed to make the ecu happy i get a steady 4.23 volts when driving i feel like the ecu wants to see between 0 and 5 volts just not 4 please correct me if i'm wrong any issue on the epidemic would be greatly appreciated. thank you more than anything Ill attempt to make a video on youtube of it bogging tomorrow
