Well I've got a100 cell cat and a blitz nur 80mm exhaust and it's too quiet! But of drinking at 2500rpm which I might tune out of i cbf...

So turbo smoke all gone with the fancy oil supply regulator?

Yeah no more smoke. Getting ready for tune. Just need to buy some injectors now.

What is the cutout? Boost activated?

Normally closed, boost activated. It opens at around 3psi instead of the stated 14psi so I need to put a boost tee in the line to open it later. It's stupidly loud hahahahaha

I found the back pressure in my exhaust would prematurely open the valve. You may find even with a bleed valve it may not want to stay closed. Have you tested it with the boost line disconnected ? 
 

With mine closed my fueling requirement dropped by 13% and timing had to be retarded up top by approx 4 degrees. other wise exhaust manifold pressure/gas would creep back into the cylinders at high rpm and cause knock.  
 

I’ve read through your thread and I’m going to go out on a limb and say the EMU isn’t safe to use on your setup. The turbo you have is quite stout which makes the sensitivity of your engine to an improper tune substantial. The time spent rebuilding engines and constantly touching up the tune will justify moving to a safer more suitable option like the LINK fury ecu. 


Benefits are substantial:

-automatically adjust fueling based on fuel pressure so risk of leaning out is greatly reduced  

-Ability to simulate MAF output to keep the transmission happy when running a MAFLESS tune  

-No hot start problems that you get with the EMU when trying to balance correct injector lag times vs injector size compensation.

-Full rpm & load closed loop wideband fuel compensation  

-Gear based fueling&ignition timing 

-CAN bus integration to retard timing and boost during OEM torque reduction requests for gear change. I think I may be the only one with this working atm  

-CAN bus integration for Gear Position status in tiptronic mode. Again not sure if anyone else has the message IDs identified for this  

-ethrottle control for torque reduction at high rpm. Solves the over rpm issues when trying to change from 1st to 2nd under big power. Enables the rev limiter to be soft on the engine. 

-Cam Angle Ignition and Fueling compensation. 

-Perfect tuning gauge display is plug n play  

-perfect hot & cold starts

-Flex fuel tuning for any combo of E85 and ULD  

-Fuel Temperature compensation

-Anti-Lag

-Cruise control 

-proper data logging

-proper individual cylinder knock control

-etc etc etc 

 

As you can see what you get for the extra $ makes a substantial difference to your ability to mitigate against unstable combustion, ie engine damage. Also protection of the transmission. I’ve been through 5 gearboxes and 3 engines so learnt a lot along the way.  First M35 325awkw. Second M35 411awkw

It's slightly open at idle so I need to put some more preload on the actuator. Even if it opens at 10psi I'll be happy.

EMU was cheap, Link is not. Basically it all comes down to money. Maybe later on I will go that route since I have made the harness plug and play.

What boost were you running on the EMU 98 tune (that's the one I'm going to put in and have the tuner touch it up)

It was running 26psi. 

Following this stage with great interest. I've for almost three same mods Brendan- and an EMU as well. I would love to go Link like Matthew has but at 3-3.5k tuned is just too much at the moment... and would be a massive over-capitalisation in my car. Having said that, I'll probably be disappointed with the EMU in the long run and and up going Link!

So you driving this yet? Wondering how the hi stall is? Wondering if i need one after last night's drag racing stalling effort....10+ secs to get just over 3000rpm. Trouble is that it's the wife's car so need something that drives almost normally.

Yeah man it's my daily. High stall is a must with what you plan on doing. 

It's a little bit doughy when I'm taking off but that's expected as it needs more revs to get it moving. When it's at the right rpm and ready to go though, it's like a freight train.

Mine still takes about 10 seconds to stall up and gets to 11psi. It can make more once I get it tuned and get some more fuel in there down low.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
