1G Greddy fv2 BOV stock 1G GST

[Chuky_4g63T]

Hello, I'm going to assemble the greddy fv2 valve model 2021 and I was curious to know your opinions and recommendations. Would it be necessary to recirculate it? Or it would be good to free the atmosphere. Thanks

Are you stock ECU and/or mass air?

Ecu 1g gst , By massive air do you mean air filter?

You must recirculate if you have a mass air sensor.

 

[curt-s]

Mass, as in density or amount of air, not massive. It's the sensor directly after the air intake filter, usually attached in one large plastic unit. It's the stock / original method of measuring how much air is entering the cylinders.
As Paul states, you need to recirculate. An unrecirculated BOV on mass air can cause all sorts of issues.

Thank you very much, would you solve the problem with an aluminum intake and a conical filter so that more air could enter? And after the council recirculate the bov

That wouldn't make a difference. The issue is with the stock ECU software and the stock air metering system the BOV should be recirculated back into the intake in front of the turbo like it is ... "Stock"

If you want to run a BOV vented to atmosphere you need to measure the air after the BOV and the two most widely used ways to do that is with either a GM hotwire mass air sensor in the intake piping and something to translate it's output into something the ECU can handle of convert to a Speed Density system where the Air Mass is calculated from flow, temp, pressure and engine VE rather than measured directly.

Or you can install it and let the car run poorly.

Recirculate the bov as you tell me I don't have the standard admission so I wouldn't have the Maf sensor how could I solve it? Since I have the admission of the gs

 

[chrysler kid]

You can spend $600 for dsm link ecu and another $200 to convert your car to speed density

Or you can just recirculate the blow off valve like the original was

If you don't have the original air filter and intake piping that goes in front of the turbo, how you you measure the air now?

Do you have a picture of the engine bay?

 

[curt-s]

Not "admission", it's "transmission"

Transmission doesn't matter. I'm with steve, take a picture of the engine bay from above looking downward towards it so we can see the entire thing

 

[steve]

I suspect this thread is being conducted via a online translator from Spanish to English given the OP is in Spain, so I'm not sure what the "standard admission" means but I'm assuming the pre-turbo intake piping.

I'm waiting for everything to get to ride right now I have it stopped.
