Ok, so today after i got my car idling good and whatnot, i decided to put it back together so i can do a good test drive. well everything was fantastic. wideband was reading perdy good, throttle reponse was nice, BOV was letting go when i was off throttle, etc.. so i decide to try and boost postive pressure a lil bit and i give it gas, ok im at like -5 vac, then i give more gas, and wideband richens up, vac is staying same, then wideband says rich and the gas isnt reponding.. until i let off and gave little throttle.. so at partial throttle driving around is fine, but i cant build boost, and give her some gas 02.gif... also, to let you guys know, i did not pressure test the intake system yet. i figured since my vac was giving good idle reading of -20 i was good. neways, i have a couple datalogs of the event if neone knows how to decipher them or would want to help me out..

thanx..

well i figured out a few things, and now i just need help on solving these problems, when i am running super fvcking rich, i dont believe its a connection problem. i had someone look at my datalog and it read ~4 and 100% input for injector duty cycle, which is obviously why its crapping out, cuz the injectors are going full fledged. He said that N/A the MAF usually wont see anything above ~3v, so could the high MAF voltage be the reason its having the injectors go full cycle?

i was also told i could fix or hopefully fix this by changing my boost limiter cut setting, but i dont know where to go from there.. it also seems throttle % related more than rpm related..

please help, im perdy new to this boost stuff.

 

no i cant boost.. because when i go to build boost by giving some throttle, my injector duty cycle shoots up to 100% and it like temp floods the system and like bogs giving no throttle response. i think its just a tuning issue, but i am unfamiliar with tuning and the software so i dont know where to start as far as fixing the situation..

 

yes thats basically what im hoping i need to do...

 

yah i thought about it, but id rather not tow it there.. i wanna see if i can trouble shoot it before i try and tune it or get $$$ help.. the injectors are running at 100% and MAF voltage is high and i need to figure that ish out..
