Need a little help with boost control

[g6e]

Hi

I cannot for the life of me get the boost to increase on the FG

I have looked for other files and tried to copy the boost settings but to no avail.

Could someone please take a look at my file and tell me where i am going wrong?

Would be greatly appreciated, the car makes 230kw at wheels on 8psi with .80's fuel, i would like to run about 14 or 16psi boost.

Car does have injectors and exhaust, so it should be up to it.

cheers guys, tuned.hpt

Which table are you adjusting to increase boost?

[g6e]

have tried increasing the desired boost map and wastegate duty cycle map.

where am i going wrong?

Can you post your stock and modded tune files please?

[g6e]

the tuned file is in the first post. i will get you the file i started with when i get back to the laptop.

thanks

here it is... I would just like to know what you have to do to get the boost control working well...

please help ???

[g6e]

the car was tuned with SCT before it came to me.... the original tuner is not available easily... but it can be if there is no other option... please help..

All the closed loop PID gains are zeroed out so the "Desired boost" table will have no affect on closed loop boost control. The duty cycle table is maxed out in a lot of places. If that doesn't boost like crazy I suspect a mechanical/electrical fault?

[g6e]

so it looks ok to you then?

do the solonoids have issues on these cars?

I've never had one fail. I've had them get a bit sticky/slow to respond. A quick clean/Lube usually does wonders

Are you 100% there's no mechanical issues that would cause this (ie wastegate stuck open/cat collapsed etc), I would suggest disconnecting the boost solenoid from the turbo and plugging the boost source line on the comp cover then run the car up and see what it does.

Pressure test the intercooler and pipes for leaks I have had issues with lost boost which was a boost leak in the throttle body to intercooler pipe rubber connector.

are you still having problems with this? I'm running 15psi (would be more but my valve springs hate me lol ) so you could copy my wastegate dc table if that helped

If you datalog requested boost does it match what is in the maps? What about fault codes anything regarding wastegate?

Sounds like the solenoid is stuck to me.

intake rubber joiner on throttle body was cut and leaking boost.
