Edit* Data logs

Hey guys

I recently bought the ap for my evo X gsr and ive tried 2 stage 1 map and im not reaching the +/- 23 psi

Im only reaching 14.

What could be the problem ?

Thank

 

Anyone ?

 

Are you running any other mods on the car? I know I was having issues when I first put my UICP on because I didn't tighten down the T bolt clamps enough. You may also want to do some data logging to see what the issue is.

 

Im running a cat-back, intercooler with upper and lower pipping and intake. But when i wasnt using cobb i was reaching 16 psi so i dont think i miss tighten my things.

I will do logs today and post it for u guys

 

Heres a logs i did yesterday

Sry for the long logs just go around 2483 sec

At 4612 you can see me reach 14

I know im not pushing it hard but u might see sometings i dont and i will post 1 later when i give it hard and you will see the psi dont go over 14

 

Well i see where you got on it for a couple seconds but never went above 3k rpms do you have a few pulls where you reach higher rpms? Or does it still not build boost as the rpms increase? But yea it should be spiking a lot higher if you go full throttle at those rpms. Are you sure you dont have a boost leak? Did you already do a boost leak test?

 

Theres my 2000 to 7000 rpm pull log on the top of the thread.

The boost dont increase as the rpm go.

No i did not do a boost leak test is there an easy way I can do it myself

 

just wondering if you unistall the ots map and just goto a stock map does it still have the same problem?

 

U mean instal stage 0 map or factory map i was reaching 16 psi before installing cobb stage 1 at the very max but ya it was approx the same boost

 

Well its pretty safe to say then you most likely have a massive boost leak then. I would go through and check all the piping connections. Because you should be spiking to 26 or 27 lbs of boost then tapering down to 17 or so. If you google search there are tons of ways to do boost leak checks. Easy way is to just get a squirt bottle of soapy water and spray the joints and if you see bubbles then your leaking there!

 

This ^.

Do the leak check as soon as you can. Boost leaks can cause the turbo to overspeed and go bye-bye. Dont want that.

 

Get a 3 port and run Cobbs stage 3.
I had the same issue and the 3 port seemed to fixed it

 

Dont we need all of cobb stuff to be stage 3 ?

 

I run a modified version of Cobbs stage 3 with the stock downpipe and catback although I have Cobbs 3 port, ams test pipe, cai, intercooler, uicp, licp. i have no issues

If buying a 3 port is not a option. I would suggest checking the stock ebc, the lines may be hook up incorrectly

FYI if the intake you have isn't from Cobb you'll have to modify it to avoid any issues with the a/f

 

Ok I will check the ebc lines.

Where did you get your modified cobb
