holy crap... looking at the log.  there is some weirdness going on for sure.

I am going to dumb the file down a bit in a few areas in the interest of getting the thing stable and then we can hunt for power from there.

i will delete the previous posted rev_5 file. 

start here, but still need the info from above because even the log doesnt really tell me how much boost you are trying to run/

the oscillation is almost certainly timing, also plug your n75 in for now, even if its doing nothing.

is there any chance your wiring is getting interference?

boost is set at 20psi with the EBC oscillation feels just like the power curve is super wavy.. like its down 20hp then back up.. its a smoother oscillation if that makes sense.

Timing for sure, can see it in the log, but your boost isn't holding either.  The ebc for one reason or another isn't holding.

I may switch to twin solenoids and dual port. I'll see what I can figure out

Do you have an mbc you could throw in just to cut down on variables for now?

Did you fix his ARMD maps for WOT?  Nyet has seen this being bothersome in many, many applications...

I did, but then just reverted to stock for now to narrow down variables. At these boost levels he won't be hitting interventions yet.

I am concerned about the maf signals, I really hope you used a shielded and grounded wire.

yes the factory shielding is there on the signal wire.

im going to try and go on a drive tonight. we are busy at work so im staying late most of the week.. the car isnt exactly neighbor friendly when it gets later into the evening.

F MY LAPTOP.. only when im driving hte car  it fatal errors randomly with a blue screen and restarts..

i had a good log of 2 back to back 3rd gear pulls and i didnt have enough time to pull over and save them before it errored.


good news though.. the car seems to handle boost MUCH better.. the first pull i did was solid and felt pretty damn quick although its still rich 11:1.. the second pull i got some minor power loss which i only assume is again either throttle cut or timing.

car holds 21psi no problem on this boost controller and i havent changed anything.  going to try and get someone to come with me so they can save logs with the quickness.

another issue i saw which is nothing crazy.. is that its idling a bit rich.. 13.8:1 or so..

Are you running ME7logger?  Switch to it if not, it can solve your log-saving issue by design.
