Mini supercharger on 1zz

[Carolyn]

Maybe the second... if the first one goes well.  Learned the hard way with rocket engine testing...

[Carolyn]

This is interesting (and expensive).  M45 Eaton on MX5.  Same throttle-body and maf position as ours.  No cooler.  My inlet is better, but their outlet is better than ours.  Uses a Mini bypass valve.  They can't spell.

It is me, or did 'someone' do a swift edit there?....

[Blue al]

Looks like They split the kit if you can see value in some of it ?

[Carolyn]

The outlet is nice, but too tall to fit under the exhaust on a roadster...

Looking good. Is the plan to recirculate the air from the BOV outlet back in to the supercharger inlet pipe?

[Carolyn]

Was just going to allow it to vent.  Unless you have a good reason for re-circulation?

[lamcote]

I understand the ECU may well get confused if it isn't recirculated. I have read that the MAF will be measuring a load of air that never gets to the engine and the system won't understand why and will try to do something about it but won't get it right. I suppose it's the opposite of a vacuum leak?

People seem to recirculate into the inlet, before the supercharger but after the MAF.

[Carolyn]

Hmm
Read up a lot on this.  There seem to be opposing 'expert' views.  We'll see how it does and ad a re-circ if it's a problem.

[lamcote]

Might people's views be different if they are using a MAP rather than a MAF?

[lamcote]

This is a common comment I see,

"Re-circulating Vs Vented Blow off Valve

Recirculating Blow Off Valve

A re-circulated BOV is one where the boost pressure is re-circulated back into the intake just before the turbo. This type of set-up is a must for those that are running a Mass Air Fuel ( MAF) sensor. The reason for this is that the MAF has already accounted for the air that is in the intake manifold, and if it was allowed to escape to the atmosphere, the car would run overly rich due to the fact that the ECU still believes that the air is in the intake tract."

enginebasics.com

Most others say the same as far as I can see?

[Carolyn]

Yes... but I will be using a boost sensor.  WE'll see. Not the end of the world to add a bit of extra plumbing.

[lamcote]

I have no direct experience of any of this so I may be wildly wrong but I am assuming the boost sensor is used to richen the mixture to compensate for boost, however you still need to know how much air is going in, otherwise you wouldn't need the MAF.

Maybe someone who has actually done this could chip in? I agree that the addition of some extra plumbing is little problem but many different things could cause a rich mixture so it may be difficult to isolate a problem to this issue IF it exists. I am trying to minimise the potential need for debugging once you are up and running.

[Carolyn]

David and I have just chewed this over.  It seems that the re-circulate option is recommended 80 - 20 over simple blow-off.  So we'll put the plumbing in.

[Carolyn]

She runs.
Well, she's idling OK and revving freely.  Don't know how she will be under load.  I removed the Emanage from the system, as it was just not behaving (probably a wrong connection).  So I started her up on the stock ECU (she's got 2zz injectors).  A bit on the loud side, but definitely legal. It was showing an eml (no code) with the Emanage in place.  No Eml with it out of the way.  Now to get the Emange to do what it needs to do...

And the crowd goes wild!!!


my sincerest apologies if my happiness at the success of this project is in anyway horrific to others eyes... ;-p
Go Carolyn!

[Carolyn]

Nothing like the whine of a supercharger.

Sweet

[greybeardgt]

From greybeardgt Well done Carolyn! nominate you No 1 Superwoman!

Now I need to spend a few hours with my' puter, Emanage and someone who really knows their stuff on this.  Any volunteers??

[shnazzle]

Should we start with the error code? Then the knowledgeable can chip in as needed.

[Carolyn]

No error code.

[Carolyn]

I'm not confident in my computer set-up and not really finding my way around the software (It may not even be installed and working properly).  I found one dodgy connection in the system, but I just really need a solid foundation on which to proceed.
