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.

    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
