Had To Re Adjust Boost Cont. After Fmic Install

[Ricos]

hi guy

i have a r33 gts-t. Ive had it boosted previously with a valve and it was set to 12psi (with stock cooler)

After the FMIC went in, i figured id be able to just wack the boost controller back in and it would sit at 12 like old times...How ever it seemed to just be running stock boost...so i adjust and adjusted till i got it back to where i wanted it. So its now at 11-12~ish.

Is it normal it did this? cause i had to wind the boost controller HEAPS to get it back up to 11-12.

Is this due to the persure loss, or is my boost controller stuffed or something?

No real dramas, just dont wanna hit boost then see my guage to 7+ 7+ 7+ 7+ if it is my controller lol

Thanks in advanced

do you have an aftermarket gauge?? (guessing you do) if you dont then the 7+ on the factory gauge is more like 1 bar. after my FMIC installed the other week my max boost went up 1 or 2 psi to around 12, so i wound it back down to 10. you got the opposite prob to me..

After thinking about it as i aim aimlesly bored at work (IT) LOL. i think i figured the problem ill go home after work fix it...

I new there would be a difference after the FMIC, but i didnt think this much.

I have just installed a fmic and found that my boost went up about 1-2psi but more so I found boost spike to be way more evident on a cooler night. Which in turn is either causing Rich and retard or missfires (fells like a miss to me but not sure what rich and retard feels like. Can someone explain?)

The above unpredictable boost issue could possibly be caused by my GFB manual bleed valve now getting a reading by being Tee'd into the BOV line. I intend to install my nipple in the I/C pipe very soon hoping this will decrease the cold night boost spiking effect somewhat.

All in all i did not touch the boost controller and boost did seem to rise slightly after the fmic installation.

RICOS - when you install a front mount , the boost becomes laggy because the air has a longer way to travel compared to the stock setup. i sugest you go and purchase an after marker boost gauge , to monitor your settings . and also psi is much easier to read .

yeah ellec boost controller is the only way to go. my greddy boost controller, bout 500 bucks, tells you max boost recorded after each throttle aplication ( boost spike). and the controller settings allow you to iorn out spikes easily, and you can flick back to stock boost too. oh and it also doubles as a digital boost guage

I have fixed my rich and retard issues by installing the nipple in the I/C piping before the t/b. no boost spikes only slightly and holds pretty steady MOST of the time. Previously was tee'd into the BOV line.
