emanage boost control

Found this the other day...

Basically, the guy is using a sub-injector output to operate a boost solenoid.

 

What do you think? Anyone tried it?

Should work ok, the only snag is having to plug a laptop in to adjust your boost, can`t do that while allready doing 140 leptons,

[Hermit]

That's true, it wouldn't have all the bells and whistles, but it's a lot cheaper

 

You could hook up a switch to disconnect the solenoid, i.e. revert to whatever baseline boost is. That's an on/off at least

 

It sounds like it would have pretty good control over boost in terms of spiking/creeping.

Done something similar with another brand of ECU, You can even set it up so that you have a compensation for different air temps based on a IAT correction Inj factor.

 

Best to have it in a closed loop setup though.

Sound like a good way of utilising a spare map, unfortunately i use the sub map for my water injection.

Thanks guys - since noones said it's a silly idea, I'm going to give it a try. I've ordered up some solenoids to play around with

Wouldn't it be closed loop though since the sub-injector map is based on MAP and rpm?

No closed loop corrects itself ie will use P+I to try and maintain a set pressure

[Hermit]

Ah right, of course. There'll be nothing in the map that tells it the target pressure. And the rows above the target pressure can't be reduced by much or it will start oscillating. Hmm, gonna have to be real careful setting this up!
