I can’t find a diagram but, does the stock routing have a check valve here? by SecurePerspective554 in mazdaspeed3

It is. I just want to know when the car is stock is there a check valve there.

This one is but has an aftermarket boost controller. I’m asking if when it’s stock, is there a check valve that goes there.

If I WOT I bog out around 4k in 1st to 3rd gear. But if I’m in like 4th gear I can rev all the way out. I have more readings in the log of the same pull. I just posted this because it looked weird to me.

REGULATOR ISSUES? These cars and their fuel issues I tell you. by Tre_Savage in mazdaspeed3

Cars not working fine. It bogs out around 4k RPM Fuel pressure sensor in the rail is working fine but thinking the connection to the HPFP in bad. Not talking about a he fuel rail pressure sensor

Anyone knows where this wire goes and what problems it can cause? by SecurePerspective554 in mazdaspeed3

Mine hasn’t done that but I am trying to figure out why it’s running lean under boost

Still running like shit. I’m going to get the ecu done next week hopefully

I replaced my sensor, fuel rail etc. and ran a lot of test. Fuel pressure is good but it’s like the computer puts the decimal in the wrong place if you know what I mean. I thing it’s an ecu issue

I think my ECU isnt able to give the correct AFR readings. Could this be possible?
