mine will drop 2 pounds of boost at any and all high boost levels. very much a pain.

 

Well if it only drops 2 psi that aint bad.
I hit 27psi and drops to 21 psi at 7k
Iam using the HKS evc5.

 

but i have a hta35r which should not drop any

 

u might have a boost leak. what bov are u using? if you are on a stock 9 metal dv you could try crushing the top a little to hold more boost.

 

Not might, he does. (GT35 guy)

2 psi isnt bad, try making all lines to and from the solenoid as shot as possible 1st, that may help with some boost taper.

 

i used fun 3 rpm to adjust for boost taper in high rpm range. holds 26 psi solid to 8000 rpm.

 

I realize FUN 3 will fix your taper issues, but I still am inclined to think you have a boost leak. Did you check to see before compensating with FUN 3 ? You could damage the turbo if you haven't. Maybe not at 26 psi, but as you go higher, say with race gas, you could over spin the turbo and that'll lead to premature wear.

 

SWOLN, where did you tap the ecu to get the rpm/throttle signal. is it pin 84 and 86 ??

Just want to make sure I have mine installed right.
Thanks !!

 

I'll look tonight...

 

I did a boost leak test and it was fine. Without the fun 3 it would drop 2 psi. it picked up 30 whp up top so im happy.

 

I was mixed up, thought you were dropping more, sorry...

 

Well you guys should be glad you're not getting 11psi of taper.

I'm going to check for boost leaks and try again.

im getting on the dyno tommorow to fine tune with Jestr. i'll finally be able to log the car and adjust boost with the evc 6. i'll report my results.

 

currently im tuned @ 311hp 327tq. with the EVC 6.

I setup the FUN 3 function. So now i have RPM showing. My question: Can i extract more power with this EVC 6 using FUN 6?

boost setting
A- 24.4psi
B- 26.6psi

 

FUN 6 is rpm x throttle position?
