Noob question but I havent found anything in my searches.

What enables you to use Electronic Boost Control? is it: a special turbo...? electronic wastegate..., special EMS..., HONDATA..??? I want to buy my turbo ASAP and I dont wanna buy something that is mechanically controlled. I want to basically have the ability to tune down my boost to say 1Psi for rainy days and say 6 PSI for daily driving and then When I want the power Just punch it in the controller and allow 12-15PSI maybe more depending on the state of my engine build.

My celica alltrac had turbo and AWD but no EBC I must have it on the integra due to the FWD and wet roads in lakeOswego, Plus driving it in the snow will sux without the ability to limit boost.

Thanks so much for the help

 

Well first off engineering wise it's always better to control comething mechanically then electronically, but that's besides the point.

You have a wastegate spring in your wastegate say it's a 6PSI spring. No matter what you can't go under 6PSI even with an EBC. So going 1 PSI is not possible. The vaccum port on the wastegate sees the boost signal and slowly opens up fully when you get 6PSI. when you reach 6 psi the valves opens fully and enough gas comes out the wastegate so you hold 6psi. Get it?

SO now you want to up the boost. Great. You can do it 2 ways. One is with a MBC ( manual boost controller) That deplets the signal going to the wastegate from the vaccum source. So the wastegate will stil open at 6PSI, but if you put a restriction (the MBC) you can boost more like 9, 10 or 11. the other way is an EBC and that bascially has a solenoid that completly blocks the vaccum source signal until the Electronic parts senses your set boost....so at that moment it completly opens the wastegate and the EBC holds the boost at your new level. The advantage of the EBC is a.) cockpit controlable (just a little **** turn) and b.) you get quicker spool because ALL of the exhaust gas is going to the turbo until the VERY last second.

BTW, make sure you have the tune to the maximum PSI you will push anything under that and over the PSI spring is possible/safe

Hope that helps

 

That helps a lot. So basically its a solenoid that controls the wastegate, Not anything to do with the turbo.. So I can pretty much buy any turbo I want and set it up EBC style

Or do I need to have an external wastegate or INternal wastegate? or does it not matter?

Thanks so much adseguy your the man

 

if your gonna buy a external wastegate then buy a turbo w/o a wastegate attached to it. if you buy an internal one then ull need to get a block off plate for it.

uhh totally false you can use one with an internal or external wastegate...your choice

you got it

you can use an EBC on any type of wastegate, check out http://www.greddy.com/tech/PROFEC_B_SPEC2.pdf

page 10 shows internal wastegate install and page 11 is external.

^^^ Dunno if I totally agree with that however nice writeup nonetheless.

Another way to control boost is to use and aftermarket engine management system which will allow you to control a solenoid (solenoid would be purchased seperately, the aem that I have uses the gm solenoid) operation and thus how much boost you run.

Not to get too off topic, but I've done a few interships and Co-ops for school and especially with machines electronic will fail more often then a mechanical system. Mechanical is pretty much guaranteed to work...unless it physically breaks. ELctronic may not sense something on a sensor or can have timing issues etc. I was told this in school and in the workplace: "aim to do it mechnaically and if you can't ...then do it electronically." I'm speaking as an electrical Engineer to so I kinda have credibility .....I'm not bashin just trying to enlighten

 

You're not the only one here w/an EE degree. Most of the essential systems that I have ever seen are run by electronics, even when mechanical means are available. That's just imho. Doesn't really mean much though.
