any help would be appreciated thanks!

 

u need a tune

 

lol thats what i am guessing but i mean how would i notice in my map?

 

i have no clue but i dont think u will

 

your tune is probably off, whats your a/f ratio? do you have the emanage or f/ic?

 

emanage. its all messed up my tune like i try to fix it but doesnt really do anything . and i dont understand the airflow chart. the guy that tuned my car messed with that but i dunno how to adjust that i mean i know how to adjust fuel by my wideband but the airflow i have no idea. plus he didnt mess with timing he left it stock. and i guess he tryed tuning partial throttle cause he said he did. how would i know if he did on my injector map from my emanage if he tryed to tune partial throttle? i am gonna tune with luiggi when i get the money.

 

lmao he didnt touch timing and your at 13 psi???!!!!??!!!???! what octane are you running???or do u have meth....thats wreckless...and partial throttle on a blue is a fail...do u have a map sensor??

 

You need the greddy pressure sensor to tune partial throttle on the emanage or that and the black box, I think. Verify for sure. But its something to go on.

 

no not even with the map sensor...i have it and got tuned my tuner FAILED horribly with the partial throttle...it did help alot but..its still all or nothing with me...soon as my car sees 1psi it richens to 10:1

 

yuh i have meth. in partial throttle when my car hits boost its lean not rich. and i do have the pressure sensor. i think i am gonna sell my emanage and pressure sensor and the harness to get the aem fic.

 

Ok then i will be going with the FIC for sure then.

 

yep definately...but its hard to sell cuz noone wants it and its gonna suck paying another 600 bux for fic and harness plus another tune...thats wats stoping me

 

Yea. GL with that man.

 

i could help you better but im not familiar with greddy but i would venture to guess that you would still want to take a little timing away but if you were in vacuum when these codes pop up then i really dont know what to tell you.....you can try and reset the computer again and drive for about 50-100 miles (should be plenty of miles i think) and stay absolutly out of boost....see what codes you throw if any...

 

Must be that better than a warrantied by Toyota FI set up throwing all those codes. LOL GL

 

i had reset it and its the same codes. one time happened when i started the car and the other time 2 times while driving on the highway to the track and work. but not at full throttle just regular driving.

 

what does your a/f look like? sounds like you might be dumping to much fuel ...wih my emanage it richens out dramaticall if im cruising....it will sit at 14-15:1 then drop to 10:1 i have to let off the throttle then cruise again and it will regulate back to stoich(14-15:1) it sux driving my car..lol if your cruising and it all of a sudden goes rich ..you will missfire plus the system too rich code

 

yuh that happens to me at like around 4-4500 rpm cruising in 5th gear. but thats the rich code now the misfiring i have no clue.

 

it will misfire if its too rich

 

lmao u cruise at 95 mph?
