Overboosting/Freeboosting

[VIP32]

Can anyone help because my RB25 is free boosting, when i accelerate hard the BLITZ SBC eltronic boost controller seems to bleep and go read as is gones over safe boost, This is not the solinoid as i have already replaced it. I need help as im scared of blowing the HKS25/30. My actuator pipe is on. Though im having problems with my coil packs but under my understanding im sure that does not effect my boost at all. Not sure what to do because the car does not perform when its free boosting.

whats your gain setting?

im not sure what should it be on. do you know

[twoquik]

well if your gain setting is up to high your car will over boost, its a 1-100 setting, mine is set at 12-15 im not sure if aftermarket turbos can be set higher but have a play try setting at 15 and see if it still does it, not sure if you also know that when changing the setting the controller will take 3 or 4 learning runs before it sets itself so you will need to do 3 runs up to high revs see if it makes a difference anyway. do you have a manual for it because i can post one up for you. is it the id3 that you have?

yes try 15 the higher you go the faster boost will come on, so if you had it on something like 60 its going to boost spike, so try 15 and do 3 runs as it will be in learn mode for a few runs and see if it makes a difference, im looking for the manual for you at the moment.

i have this sorta issue to, ill try that

[VIP32]

thanks alot mate, ill try that this arfvo but ithink my boost setting is on at like 30 atm.

also i thing to remember, in auto mode the reading is in psi/bar ect but in manual mode if it says 20 this doesnt mean 20psi its a sliding scale of 1-100 same as the gain setting so watch your boost guage to make sure it not something crazy like 2bar
