I installed a greddy bov 2 days ago i dont know if that has something to do with this but this morning i got 2 codes 1 for system to rich, and the other was like o2 CKT no activity bank 1 or something like that. I have the vishnu xede unit if that might have something to do with it. i cleared the code and it came back on 2 minutes later. any ideas anyone?
thanks!

 

any ideas?

 

With the advent of Ecuflash I have no idea why anyone wants to run a standalone any more. Anyways, do you have a straight (test) pipe installed (may have caused the rear o2 sensor code)? The first code seems like it may be related to your BOV valve (venting causes you to run rich after each shift). Is it being recirculated or vented to the atmosphere?

 

its vta. its not really a standalone more like a piggy back but anyways i might just put the stockie back on until i can get it up to get tuned.

 

so im getting like 35 miles to a quarter tank of gas!! im going back to buy the stock bov tube and put it back on asap!

 

Yeah, the problem is definatly your VTA BOV. I had both the exact same codes when i had my Forge RS VTA. Just recirc'ed it, and called it a day, no coeds since.

 

Former owner here....your problems are with the bov. You can't mess with the bov or other stock intake parts when using the Vishnu setup. The car was set up with the V390 parts according to Vishnu specs. The "map" loaded onto the piggyback chip is designed and tuned for the current setup of the car. If you start swapping parts out you have to retune the Vishnu chip.

Take a look at the Vishnu website and on this forum and they do a good job of explaining the way vishnu sets cars up.

PM me with you phone number...I would be glad to talk with you about the car.
