Subaru AVCS no response

Hey guys, I've been doing this build for a customer of mine and gone through some probs... I need some help. Lol

The following is the list of mods:

JE time attack fsr pistons 99.5mm

COBB lightweight connecting rods (titanium alloy material)

King Engine bearings(main and rod)

Darton Iron Dry sleeves

Heads

Brian crower 280 cams street spec not drag spec

Brian crower +1mm intake and exhaust valves

Brian crower 6mm valve guides(magnesium)

Brian crower single spring/titanium retainer kit

Brian crower adjustable cam gears exhaust (intake is still avcs)

Supporting Mods

Cosworth High volume/pressure oil pump kit

Deatschwerks Fuel injectors 1000cc/w top feed fuel rail kit

ACT extreme duty 6-puck disc clutch kit

ACT prolite flywheel

Denso iridium two step colder plugs

Gates racing timing belt kit w/ water pump

arp case bolts

arp head studs

omni power 4 bar map sensor

cosworth 154 degree low temp thermostat

TGV deletes

EGR deletes

Link G4+ plug and play v10 STi

Forced Induction

ATP GTX 3071R GEN 2

Upgraded internal wastegate 22psi

my problem is no matter what values we put in the vvt table the car doesn't respond

for example:

let's say 25 degrees @ 3500rpm

or 70 degrees @ 3500 rpm

In the link when you press f12 and read the live data the vvt target and actual change and are very logical

But same boost build same lag nothing changes

the car is building boost so slow

It starts spooling @ 2300 rpm we have around 0.3 bar then gradually rises with rpm rise @ 3500 we have 0.5 bar @ 4000rpm 0.7 bar @5000 1 bar @5,500 1.5 bar which is very weird... any thoughts? should I change the offset?

Please find the tune file below.

Just to make sure I understand you correctly, you're saying the cam angle follows target but making changes to the cam target has no effect on the engine power/torque? Have you gone through the process of calibrating the VVT cam angle offsets? I just worry when you mention something like 70 degrees because you won't be able to get anything like that sort of advance from the intake? I'd imagine you'll probably tap out against the mechanical stop with around 38-40 degrees on that engine.

Give me some more information or perhaps a log file showing the cam angle and I'll see what I can do.

Hello andre, yes the cam angle follows the target but making changes to the cam target has no effect on the engine power/torque.

I havn't calibrated the cam angle offsets, since I thought that they should'nt be different from a base file for subaru v10 sti. Do you think the cam offset is the issue? 70 degrees was just a number I set out, lol. Yes true the mechanical stop would be around the degrees you mentioned. I can't provide a log file at the moment since the car is disassembled, installing some new parts....
