injection duty cyle maxed

Good morning,

I am writing this post today because almost everything I have tried to fix a mazdaspeed 3 2007 issue has been unsuccessful.
Regarding the car mods:
Long corcksport stage 1 engine block
turbo k04
fmic jbr
3 inch jbr intake
3-way corcksport solenoid
full decata

For over 2 years my car has not been running well. Almost all the sensors have been changed, map sensor, crankshaft sensor, turbo, boost leak test, compression test, internal tank pump, hpfp pump, at least 20 different maps etc ...

I have attached a journal to this post.

Currently I am in e50 mix mapping.

As soon as I accelerate the car jerks the revs are not clean. The duty cycle injection is very fast to the max even with pressures of lower k04 I had a gt28 with 18 psi it was the same.

I have maf to wot values which are similar to gt28 pressures. The mafcal has been done several times but the values are constantly moving. Has this ever happened to anyone? I am not very comfortable on the internet but I despair if anyone has a research lead I am interested thank you in advance.

 

Welcome!

In rows 21 through 23 of your log you are dipping into the 1400s for fuel pressure. Anything below 1600 is not good.

You mention replacing your fuel pump, but have you tested/replaced the pressure relief valve on the fuel rail?

I dont know much about the Gen One tuning, but are the WOT Short Term Fuel Trims in Column U normal? Maxed at +26 it looks like.

 

yes the complete rail and injector changed by those of a car which I was on operation

 

Are you sure you have an OEM maf sensor and not some cheapo toyota parts store one? The log looks ok besides IDC being to the moon. Why are you doing e50 on the ko4? You can max out it pretty easy on an e30 mix. Do you have the fuel gravity set right in the tune?
