Are you really running a bov?? Eww...

 

the more noise the better

amidoingitright??

 

It's either that or live with the 30+psi spike I get in between shifts currently with just the bpv..

lol.. hey it's the only way I can impress the local ricers with my cobalt!!

 

That sounds weird but at the same time awesome.

 

Nope, not in the least bit awesome I can assure you. I have many logs from other cars showing similar large off-throttle spikes like this. The bpv just does not react fast enough unfortunately. It's bad enough to where it can actually cause damage to the turbo itself. Here are a couple screen shots. The first one is with just the bpv and the second one is the bpv and bov together. Notice the circled large spike and turbulence/flutter over the maf as well. Not cool. After I installed the bov it miraculously disappears.

 

Hmmmm. Now I want my laptop to look over some of my logs to see if mines doing it. Is it just from wot pulls or just between normal shifts?

I didn't so much notice it between shifts as much as I did at the very end of a pull. I just pulled up a log David had sent me from your car a little while back. You are indeed getting a spike as well in this log.

 

Wowzers. Very interesting. Wonder if there is anything else that can be done about it.

Not that I found unfortunately. I tried tuning it out via the surge limit tables, but to no avail. It's a mechanical issue so I don't think it can really be tuned out regardless.

 

Buy an LSJ!

 

But then he'd have no power, so what good would that do??

 

Hahahahaha. How about it.

^ nice, looks like it's going to be a good turnout! My friend with the mustang is def in now.

So, cobalt with the most power buys lunch for everyone?

 

Yeah! 12 peeps for the dyno!

 

Go Sox!!

 

So jelly. My parents went up Thursday night, stayed there fri sat AND sunday for the games. Didnt even ask me if i wanted to go.

 

Oh nice! This was Friday night when they clinched the division. Good time good times!

I wish I had known that you were a Sox fan. I actually had an extra ticket and I might have invited you to come along if I had known. :/

 

who does trifect tunning who would be able to come over and check out my car and see if its the tune messing it up. I cant drive it because i never no when its going to start or not. The dealer had it for almost a week and they cant figure it out. everyone is scratching there heads at this time.

 

Have you tried cleaning the PCM connections?

 

Where if it located ill take a look at it. I replaced the starter and battery and it still sometimes will start and sometimes the starter will just spin and the motor wont do anything.

 

It's the connections going to the cars computer. Undo them, clean out both sides with some electrical cleaner, let fully dry, re-seat the connectors and hopefully that solves the problem.

 

im excited to dyno.

 

where is it located on the car?
