hey guys i was seeing if you could help me out. i just recently decided to start off with a fresh tephra map, i went out and did a pull at 25psi and knew it was going to run super rich, which it did. towards the top of the pull the car cut out hard. felt like a fuel cut. i checked the logs and it showed that my duty cycle was 110%+ then went 0 on duty cycle and pulse width. i figured maybe i just maxed out the stock injectors because of how rich it was running. no biggie, i had pte1200s sitting in my garage waiting to be installed. i threw those in, scaled them based on the info i found on this site. car started up and ran great. went out and did another pull and the same thing happened except now the duty cycle is down in the 50s. i double checked my settings and made sure there was nothing to do with fuel cut.
my question to you guys is, do you guys think the hard fuel cut it from running too rich or maybe something else, like the fuel pump or something? i also just added a forge wg the other day and am currently running 18psi but its still doing the same thing. im prepping my car to get tuned but dont want to waste my time and the tuners time if there is another issue that i need to take care of before hand.
i have attatched a log from earlier today and also my current tune.
i did order a fp gauge which will be in tomorrow.
thanks for any help you guys can provide me with.

 

next time it cuts unplug the fuel rail, put a bottle over it and turn the car to ON (don't start) see if fuel comes out. If no fuel its your fuel pump. If fuel comes out your engine might be going into limp mode

 

the car only fuel cuts/ falls on its face when its under load at high rpm. after i let out, it runs just fine, so i think the fuel pump is running with at least enough pressure and volume to make the car drivable. im wondering if maybe the pump is on its way out and cant keep up with demand anymore under load at high rpms. if it was going into limp mode, i would think it would throw a cel. this is why i am kinda wondering if maybe its just running too rich, just dont know why the injectors would go to zero??

 

well, just incase anyone ever wonders in the future, i think my problem is resolved. i uploaded my old self tuned map and scaled in the injectors. went out and did a pull and had no fuel cut at all and i did the pull all the way to 8k. so it appears that the fuel cut was a result of running too rich.

 

if boost level exceeds the values in your boost limit table for x amount of m/sec the ecu will fuel cut which has nothing to do with your actual fuel pump or pressure

 

yep, i set all those tables to 319% and it was still doing it. the stock tephrav7 map and the tuned tephrav7 map are identical in every way right now except for the fuel and ignition maps. thats why i believe it had to do with running too rich.
