hey guys i just installed the a new turbo on my car and injectors along with fuel pump and the car is acting funny need some help..mods include tbe,accessport,850cc injectors walbro 255 fuel pump, blouch dom 3.0xtr 2.4 inlet and bigger tmic... the problem im having is that the car like hesitates in 1st and 2nd...second wen i get on it it cuts out in 4th gear and the check engine light and the cruise control light comes on any ideas?

 

did you pull the code out?

 

there was no code

 

all the hoses are nice and tight, no air leaks?!

 

yea 1 of the wires on the maf sensor is loose like i can pull it out

 

ok you mention that you a have a cobb AP....do you have a protune or are you trying to use an off the shelf map (stage 1/2) with you current new mods? more details please

 

that might be the cause of it, thats a very important sensor i had to get a new one. when mine stop reading i had a fuel cut @ 4000 rpm hella weird. the sensor may have shorted out

 

yea i think that was it i pushed it in for a temporary run and it went threw 4th ima saughter it in thanks for the help guys

 

I was gonna suggest to call Matt at Benchmark...but glad to see you got back on the board!

 

and its back to doing what it did before it just cuts out in high gears wen i floor it and the check engine light and cruise control light is on but cant read the code i let a buddy use my accessport

 

Did you get new maps for the mods you installed?
Are you able to see the max boost you are hitting?
You need to get it tuned before you beat on it with those mods.

You might be having boost creep, if you have a full TBE, then you probably have it. A boost gauge will tell you what pressure you are at. Fuel cut occurs when the ECU senses boost in excess of 17.5psi for 2-3s. Do you know if you were getting fuel cut? It would be a very violent "stutter" from the engine that resembles extreme knock, followed by CEL.

 

I have a code reader. If you can come by the airport/nimitz area I will check it out for you today.

Check grounds. all on engine and ecu ground.

or sounds like it could be your speed sensor.....Does it start to cut out right around 4k?

 

its like wen i get on it cuts out its hitting 26psi and cuts out like a hard knock

 

have a tune for my 850cc and dom3 on the accessport already tuned it

 

It might be hitting the boost limit (Fuel-Cut) set in your ecu...
