Question About OFT tune and Boost controller
Hey guys I am new to the forums here. I've been owning an Fr-s for a year now and will soon be turbocharging it with sbd kit using the oft. However, I was wondering if I turn up the boost from the base (10 psi) to let's say 14psi, will I need a retune? I will install turbo kit in about a month from now. I asked shiv but obviously he's a busy man and all. Thanks in advance for help

Yes, a fourty percent increase in boost pressure will require a re-tune...

Word of caution:
The oft requires a manual boost controller and cannot use an ebcs. Someone in the Facebook group blew up his car using a mbc with an oft as it made the turbo spool quicker and it was too much torque to low in the rpms |

That is possible. I was told they could ramp the boost in with a ebcs so you weren't making too much power to low in the revs.

yes

You're not likely to be making too much boost in the lower rpms with most setups. Jaden p.s. also remember that an ebcs (or any boost controller for that matter), can only limit boost to the spring pressure or raise it. I'm not aware of any that can lower it below waste gate spring pressure. |

You're definitely correct about the spring pressure. If you were to try to run a lower pressure with a lower psi than spring is good for, it would be the same as not having the boost controller. |

There's nothing stopping you from using an EBCS.
Quote:
You absolutely can use an ebcs with OFT, you just can't control it with OFT. It basically becomes a manual boost controller with an electronic knob or a circuit that you build or have built. At least if you do it that way, if OFT develops the ability to program for an EBCS or you switch to ECUTEK, you don't have to worry about replacing hardware. Jaden |

Yes, a manual boost controller can spool faster, spring and ball type make a significant difference if used on a single port internal waste gate. Waste gates are not an on off device, they creep open which slows the response. The ball and spring keeps boost pressure away until it blows open and lets the boost hit the gate. This makes the gate closer to off on.
