Thread: Boost by speed option

Just would like to see how many of you guys that are running this ecu are using the boost by speed option and how do you guys like it? I love everything about this ecu and am still learning how to use it. I just lowered my wastegate spring from 17 to 10psi and added the boost solenoid last night. If a couple guys can share how they set theirs up and how it's working out for them would be awesome. Thanks

Damn, 98 views and not one reply. Is anyone even using this feature?

didnt know there was boost by speed ...I have been looking forward to trying boost by gear though...just gaotta put a smaller wg spring in and play with it

It honestly depends on each car and what tire and suspension setup the car has.

I generally try to get the car's low boost to be whatever I would want to run in 1/2nd gear if traction limited and then turn it up from there.

The NismoSA system is designed to use the gear function, so it would be boost by gear, so not directly related to speed.

I start by using the non-boost by gear settings and adjusting the set duty cycle percentages and then record what duty cycle makes what psi.

Then you can start filling in your boost by gear tables with the percentages that equal the amount of boost you want to run in each gear.

Hope this helped!

@JKTUNING yea I appreciate the reply! Hopefully I'll be getting around to setting this up very soon.
