Big car issues at the moment!!! I have 2 codes coming P0102 Mass or Volume Air Flow Circuit Low Input and P0335 Crankshaft Position Sensor A Circuit Malfunction

The car is running like shit idle is alright when I rev the engine it barely wants to rev and backfires badly ... Car will barely move !!!

Is this because of my turbo is fucked not getting enough air from the turbo seems it's not sucking in any air! Any one for some help?

Sounds like the FIC. Who tuned it? Plug in factory ecu to see if it idles fine. Or usually the FIC comes with a harness bypass plug... Unplug the FIC and plug in bypass harness. Also check to make sure all couplers are secure.

Do you have a boost gauge or A/F? Might be a vac leak but most likely the something with the FIC since you have the P0335. As Blown said use the supplied bypass harness n see if that fixes it then you kno its the FIC.

Alright guys moment of true unplug AEM fic with the boomslang I didn't use he by pass my car is going to be tuned next week so hopefully car can make it there and then they can plug in the harness and bypass and tune it!

After unplug AEM fix car works fine again .. Tuner said dont waste money getting Air/fuel but I am gonna get one make sure!!

The bypass harness didn't know it was need .. Where does it even connect to and wat does it control I feel like sub a noob!

alright here is my problem! when i disconnect the boomslang harness from the ecu the car runs fine! if i plug the boomslang into the ecu and put the bypass harness the car runs like shit .. rough reving and jumping idle problems!! so is there an issue with my boomslang harness or wat? then when i plug it into the aem fic .. it seems to run fine with only once their was power loss for a split second!! i dont think the boomslang works with the aem fic bypass it doesnt seem to work!

The boomslang should work fine with the bypass. With fnkngrv's boomslang I found that two wires on the male connector had broken loose from the pins. The male end uses a connector that is harvested from an ECM, so rather than having pins which are crimped to the wires, the wires are just soldered to the tabs that would go into the printed circuit board in the ECM. If any of the solder joints aren't perfect, they will pull off with vibration.

Check my connections everything seems fine!

After driving around everything fine that one spot where I have loss of power is at low revs when I full throttle it the car has loss of power and makes noise from exhaust as if valves are opening and closing and u can hear it thru the exhaust! Taking my car in 5 days time to fix o2 sensor and the dyno tune! Numbers and dyno sheet hopefully will be provided :)

^ sounds like pinging. What grade gas/fuel/petrol (whatever they call it down under) are you using?

What are you using to monitor A/F ratios? Hopefully not the scangauge, it's far too slow to be helpful with that parameter.

Okay car went for a tune i am picking it up tomorrow in the morning!

apparently At 5000rpm when the mixutre is lean the car pushes to redline but apparently when they add more fuel to keep it stoich the car cuts out. he doesnt wana lean the mixture cause it damage the engine. he said maybe a walbro fuel pump or injectors would solve the issue i am going to order 1zz injectors and hope it fixes the issue!

Otherwise the car is running extremely well apparently and they are happy with wat tune
once i get my car tomorrow i will be able to see how it runs and go from there..

What is the duty cycle of the injectors looking like?
They should be able to tell 100% if that's the problem. No guessing allowed.

man i dont know anymore!
getting my car back they told me that my max hp was 129HP if that is true which i dont know is like 20 hp gain on a turbo which i believe cant be right to top it off the dyno was done in 4th gear which i think to be sure should be donw in 3rd gear?

once i got home i looked at the tune the guy did and looking thru the maps he only adjusted the ignition map and fuel map

the o2 map havent been changed or messed around with at all as soon as my a/f gauage arrives i am going to install it and see how the AFR look! car runs up until 5000 rpm where seems to lose of power from fuel

and garm i asked him wat my duty cycle was and he just gave me an example about how at idle they may use .8 volts and at full throttle they could be using 3 volts and injectors arent the way to go it is better to ungrade fuel pump so that when the injectors are opened it would squirt more fuel into the engine when the injectors are open
