Hydra & FM users - what does your PWM map 2 look like?
 

I am trying to tune the Hydra so my boost comes early and stays at max boost throughout the rpm band. Right now, I have an increasing function where I don't get max boost until almost redline. I did adjust my wastegate earlier today, and that seemed to help matters quite a bit, but according to the data, my boost ramp looks about the same. FM says to adjust the PWM map 2 but I don't know what a 'good' curve looks like. I would like to see what you guys have and how far I should adjust it.

Thanks!

This is the wrong board for you man. I think you represent 50% of all the Hydra users here.

though Y8s seems to have the boost control "under control" - I'd pm him

he's using a MBC.


I'm not using hydra, but the idea behind my DC target is the same.

keep the valve closed as long as possible.

you can see there is about 200RPM where the valve opens up to its target DC%, the rest of the RPM range is solely for keeping the boost flat. notice I have a dip that I've tuned out by increasing the DC%

i'm using a $10 manual boost control.

This is the best I can do for you though:

note you'll have to make changes depending on whether you have an internal or external gate.

Ok, thanks for that feedback. I will focus my attention on the 'other' forum ;) where there are more Hydra users.

braineack, that actually helps me quite a bit. The profile they have set by default has very low numbers for the low duty cycles. I had a feeling this is what it should be, but I didn't want to make such big changes without some sort of verification. I will try it out today and let you guys know how it works out. Thanks!

Curious, why the mbc if you have the ebc option?

I think you'll find this board is superior in every way except for number of Hydra users.

For $2k, FM should be more willing and involved in setting up that kind of stuff for you.

:werd:
oh wait, I was doing the same thing because I was too impatient to get my EBC working and tuned. :gay:

I agree with Ben- and think Jeremy could give some input on where you need go from where you are via an email.

i spent a few hours trying to get a GM boost valve to work and never got it to change my boost level. i knew it was working (could hear it and do the "blow through" test just fine) but I gave up dicking around with it and threw an MBC on there and haven't bothered with it since.

some day maybe.
