i got a turbo b16 tuned on hondata s300 using a mac solenoid all of a sudden i get a cut in third gear only at 8000rpms? my redline is at 8700 and the car sometimes does a jerk when im cruising around 3500-4000rpms could this be fuel related?

 

Datalog a pass & see what is going on...

 

your right but i really dont know how to record and save and i don't know how to read the datalog to see whats my problem is, i THINK its fuel cause last night i filled the car up with gas did some runs and it was perfect so i think its lack of gas pressure

 

and it only happens in third and higher gears not first and second

 

If your car is cutting out at wide open throttle & you don't have a wideband oxygen sensor gauge installed in the vehicle. I highly recommend you take the car to your hondata tuner to have the vehicle inspected to ensure the air fuel ratios are still on par etc.

 

will a restrictive dump tube cause creep cause i purchased dump tube off inline pro and had to cut and weld a little smaller braided tube to the inline pro dump so its like 38 to 35 the tube will this choke cause boost creep???

 

Sure it can, it would have to be a tiny, restrictive dump.

Simply guessing at what is going on is pointless.
Connect a laptop & datalog what is happening with a wideband or take the car to a tuner.

 

damn mtber...you got more patience then me.

 

im datalog my car later today and let you guys look at my file thanks for helping

 

well i finally did a data log it looks like it was hitting boost cut, its set at 16psi but why would it boost cut i have a inline pro manifold and 38mm tial external wastgate with a 6psi sping in it this should be good right? any thoughs??? here is my file so you guys can look at my datalog

 

i also lowered the duty cycle from 50 to 45 then it relined perfect no cut did i lower the psi?

 

If you lowered the duty cycle on the boost control, it lowered the boost. Congratulations you have resolved your issue.

 

lol ya i guess i did but one thing that confuses me the tial wastgate is suppose to hold this boost perfect correct? what would make it creep like that at higher rpm
