Doubtful you'd be building boost at low speed light throttle so I'm not sure you can expect anything different there. Do you have a tune? do you use stock or sport mode throttle? Do you have an aftermarket intake or stock? Curious due to the noisiness you mentioned.

 

It's at my signature...
Alta CAI with K&N filter, Alta turbo inlet, M7 Pre-Intercooler Charge Pipe, Alta boost\Water gauge, Milltek catback,
Alta Stealth intercooler, BSH OCC, Evolved.

low speed light throttle testing it on purpose for the noisy...no boost build, but hearing the leaking noisy...quite annoying... seems a bit lag by that....


not sure if Alta can provide an official video after it is installed.

I found the one in youtube...but quite difficult to hear the detail.....

btw, i did install the o-ring in as well.

 

actually, does it fit in any position? meaning, would it match the hole in any position? or only 1 position match all 3 holes?

 

the gasket does not seem to fit as nice as the original. I don't think it sealing well. The grove in the new BOV is deeper. Maybe I should try a new gasket. If I didn't get a good seal would that make the BOV get and errors? The guy at alta said I was not getting the pin in right. I tried three times I'm sure it was good. My accessport gave me two errors that I had a leak and the BOV was not work.

 

Donut, try a full throttle run and watch your boost gauge. If the boost is lower than expected, you should double check the BOV to make sure everything is lined up and sealing correctly. There's only one way that the BOV can be installed. If all else fails we can take it back to check it out.

 

Sorry man, was replying to your post from the app which doesn't show sig lines.

 

I just installed this over the weekend and can tell a difference with my Stage 1 tune. I didn't release how much the turbo surged before. Now everything is linear and smooth. Before I saw spikes 19-21psi now it spools and stays at 17. I will be soon changing to Stage 2 and then 3. What PSIs should I be looking for at those stages?

 

Here's a question concerning the resistor. Would you be seeing a code/CEL if it were not installed correctly/making sufficient contact?

 

Good to hear Taz That is a good way to describe the improvement, linear and smooth. Keep us posted on the stage 2 and 3 tunes.

Funny all this talk about issues. Went driving this evening and the car wasn't feeling right. Decided to plug the AP in to monitor boost and even with my foot deep into the throttle I'm not seeing more than 9 psi with the occasional swing up to 14 but usually well below. I don't get any boost at all without really putting my foot into it. It was to late to check fittings etc but everything seems tight from a cursory inspection. Does this sound like a resistor issue? Ill check all the boost tubes etc. tomorrow when I can get in and under the car.

The DV has been working like a charm but

 

2nd run today. It can hold boost...20psi, the sound is rom -10 to 0 only when I m in stop and go traffic, i think it is more like sucking not leaking...before -10 and after 0 is all normal. the lag feels like between -10 to 0 and the sucking sounds, once step on it passed 0, it is perfect...feel stronger than before...

is this normal....as vacuum suppose to release from the CRV to the mainifold? but it sound like airfilter sucking air....or leaking...I can't really tell.

I have evolve stage 1 and running on sport mode

sorry terminalvelocity....wasn't meant to mean anything...

thanks everyone for the feedback

 

No worries man. I didn't take it that way!

 

What map are you using?

This AM I put the Stage 2 TPS (what I run in summer and most familiar with), and in stop and go 0-55 traffic I never saw anything over 9psi. Hard run on ramp saw 16-18, and then a WOT 6th gear pull saw 19.9psi.

Before the the Diverter Valve I would see 12-14psi in stop and go traffic, with peaks of 21 on ramp runs.

I'm choosing to think of this as a good thing. While technically less boost, it is a more consistent and predictable power band. I would love to see a comparison of dyno charts with the DV.

 

Donut, you might want to check the vacuum line to make sure everything is connected correctly from the boost port to the BOV. It almost sounds like you're describing compressor surge at light throttle.

How did the ALTA part fit into the hole on the turbo? Did it seem to fit tight?

 

I'm running the stage 1 FMIC 92+ oct tps(linear) map. What you describes sounds fairly consistent with what I'm seeing. Maybe I'm imagining it but it just felt like I really had to lay into the throttle to get any boost effects at all. I'm gonna plug the ap back in and go for a drive here in awhile.

As a side note, when you guys installed your resistors was the resistor wider than the female plug opening you installed it in? It forced me to pinch the "legs" of the resistor inward and although it felt like I got a good contact it seemed iffy.

 

For sure it wouldn't be a resistor issue, the resistor just tells the ECU that something is plugged in. If it's not making a connection, you will get a CEL.

 

Yeah my resistor fit like that \_/. Frankly I expected the wire to break from all the bending. No too pleased with that part of the kit. Need to figure out a better long term solution. One thought was to get another resistor and using solder reinforce it.

 

.

Ok thanks Chris. I assumed so but thought I'd start with the easiest fix.

 

yes, the resistor is longer than the plug.... I was afraid I will break it as well.

just in case if the pin breaks, what resistor should be replacing it?

I really can't tell how the surge sound like... I will try to find someone to take a video with me together... the CRV looks tight... though

but i will check again over the weekend...

btw, it runs great except having that sound...once I step more on the throttle more(quick)...right above 0, won't realise that....

 

Can someone from Alta confirm the resistor used in the kit so we can get spares. According to my note the bands where: red,brown,black,brown,brown...or brown,brown,black,brown,red. Should have took a picture.

 

This is a good idea, I would like to have a spare as well. In terms of how it's installed, I cut a good amount off the tails, so it fit nicely into the connector and then used electrical tape to secure it. I also secured the line with a zip tie to keep it in place. What is everyone else doing?

The resistor is a 2.1k ohm. The resistor wires should have came folded in half, like the picture in the instructions. Instructions can be downloaded here.

If they didn't come like that, you will have to fold the wires yourself and trim the wire a little, sorry about that! I'll let the guys assembling these know right now.

 

TerminalVelocity, have you tried going to a non-linear map to see how your boost behaves?

 

1/4 watt yes?

Mine was folded over. Might consider putting 2 in a box just incase... A quick internet search shows these aren't a terribly common size, so getting at a Radio Shack might not be an option if one breaks.

 

Is the sound is like a slight whistle? While only partially on the throttle while still in Vaccum you will hear the DV whistle. It is normal and does not effect anything. Just takes some time to get used to!

My experience so far is that if the resistor goes you will get 0 boost. None. You will not even hear the turbo and the car feels like poo. But I never got a cel or limp mode. So it would be something to check.
