Does any one know where i can get one at? JGS precision tool no longer sells them and i can not find any others. Thanks Also, would I still need one if I have AEM F/IC? Its not a full standalone but I did not see anything about piggybacks in the BOV section of the DIY turbo FAQ.

 

check valve for Bov? like a 1 way valve? you would either be stuck with a BOV that is always open, or will never open.
you just need t tighten the bov spring if you are leaking at idle

 

I used a check valve from the plumbing section of home depot when I was one the stock ecu. Worked like a charm and also made the BOV significantly quieter. Check home depot, lowes, or a hose shop if you have one around you.

 

I was confused about what I read in the DIY FAQ. "If you are determined to run your BOV VTA (vented to atmosphere) you must install a check valve on the open end to prevent leaks at idle. A few websites sell these devices. Without this, you have created a very large vacuum leak and the ECU will not be able to compensate for it, result: bad or no idle."
So if I tighten the spring it will fix that issue?

 

I'm not exactly sure where I would put the check valve, does it go where the vacuum line would be on the top of my BOV?

 

dont run the stock ecu, no issues.


bandaids are for aids.

 

are you still running the stock air flow meter? if so you need the bov to be closed, if your on a map sensor, it wont effect it.
you could recirc the BOV back to behind the AFM, thats one way

 

Well I don't want to use the stock ecu but my problem is that AEM standalone is too much for me, and I dont know of anyone in my area that can tune megasquirt.

 

I have a MAF, I dont know if that changes anything. But I understand what you are saying.

 

fellow member on this forum do have some base maps you can work with, if you get base maps, and purchase the full tunerstudio, it has a autotune function. just dont go around nailing every 3 seconds until you can get it tuned

throw the stock ecu in the trash, you also need bigger injectors and a wideband

 

Yea, i have been in the market for a wideband, but im still unsure on what injectors to get.

 

what turbo, what motor, how much boost, and what fuel?

 

Hopefully a t28 but possibly a t25, 1997 1.8, 92 octane fuel, and around 10 to 12 psi

 

ok so 1.8l on 10psi, what size turbo, thats just a flange

 

Gt2560r or gt2860rs

 

id say at bare minimum 305cc, id recommend atleast like rx7 460's
never hurts to go bigger than you need however
