The IS300 gets a BIG UPGRADE! EMU black install!

[@jasonmcqueen1411]

Great info in this video. Thanks for taking the time... "Saved" for reference later for when I do my 01.

[@Knownworldwide]

Thanks man.

[@edgarrojas9628]

I have the emu black on my car and let me just say after you setup the basemap with the correct injectors timing and set up the fuel map to your liking, the car is extremely nice and fast for what it is and havent had any problems so far👌

[@Knownworldwide]

Thanks bro! Yeah I took it on a first drive today to do some road tuning. It feels way better than with the FIC! Night and day. Still making the same boost as before but I swear this sucker is strong! It’s far more smoother and the computer reacts much quicker to my throttle inputs and it holds rock solid AFR/lambda targets. Can’t wait to go manual to get rid of the electronic TB. I need to install a throttle lock though. Do you have one?

[@vincejordan2715]

Just dropped off my CX racing pre throttle body pipe to get the IAT bung welded on a few hours ago. Perfect timing! Hoping to have my emu black installed tomorrow with that done

[@Knownworldwide]

Yes sir! So far it was pretty easy to setup.

[@HIHGSCHOOL]

man I’ve been following this build after i decided I’m going turbo on my is and looking on KZbin you uploaded the vid buying the cx kit. I’m going to start taking the car the part hopefully this weekend

[@Knownworldwide]

Nice! Hope you decide to stick around for the long run! Appreciate you taking your time to watch. The CX kit is good for the price. However watch some of my past videos and you will see that the CX provided turbo sucks.

[@HIHGSCHOOL]

@@Knownworldwide yes sir I’ve watched all videos related to the is. I actually bought the cx manifold alone months ago and wanted to buy everything separate since I wasn’t sure about the cx turbo being good long term and I’m glad I did. I went ahead and got the same turbo you purchased

[@MidwestMechanic]

Man been waiting for this video to drop. Hopefully i can get mine this year with my Christmas bonus shit ain't cheap but hopefully it's worth it in the end. I don't see why i won't be.

[@Knownworldwide]

They are definitely expensive haha. Made a world of difference.

[@mardicas]

This made me re-think of my plan to use a piggyback first (CC and Traction are important to me) and later go full standalone. Ill probably go standalone immediately and figure out the CC and TRC later.

[@Knownworldwide]

Well really what it comes down to is cost. I paid $250 for my piggyback when I first installed the turbo kit. It worked ok for the overall picture. However after some time it starts doing odd things and needs to be reset. Fuel trims start to get out of hand and it can be frustrating to deal with. If you car is automatic, I would definitely suggest going with the EMU black or the Link setup for sure. A pit pricey but you can find used units sometimes for a good deal. Thanks for watching! I hope you decide to stick around for the long run!

[@mardicas]

@@Knownworldwide I have a manual swap done already and on the stock ATM ECU (I got CC working too). The kit I am starting to install already came with a piggy(DET 3). I also already have an EMU Black(that I might use on anohter car too). So I was initially thinking that for the ease of setup to go with the piggy (to retain the factory stuff without majour issues) It is my winter beater lol. But yea, seems to make sense to go with emu from the get go even though Ill have to get something else for the other car later on($$$).

[@Knownworldwide]

@@mardicas A buddy of mine was trying to get his DET3 up and running on his is300. He has been running the FIC for 3 years and while it has been working. He hates that he has to basically reset the thing every 4 months because it starts acting weird. He also has a EMU black that he picked up for cheap. He tried the DET3 but he told me he was gonna go with the emu due to ease of operation. Either should work fine I would think.

[@husband_things]

​@@Knownworldwide It really seems EMU Black has it figured out. I wish the plug n play harness was cheaper. With shipping and import tax it will cost the same as an emu black itself lol. And it seems to be an US product only.

[@Knownworldwide]

@@husband_thingsThey are based in Texas. I would say that you could look into the Link setup but that setup is usually around $500 more on average. My buddy picked up a used EMU black for around $750 and it came with the PNP harness too. If you're not in a rush then maybe that would be the best option.

[@LegitRaceCraft]

Nice video! The fic6 was on my car when I bought it and I kept messing around with it and it would revert back as you were saying. I'm more familiar with haltech and autronic engine managements, I've never liked anything aem. I've got haltech on mine and I made my own parallel harness. Good job on keeping that aem wideband away from your engine management lol, the signal is slow from the sensor to the gauge and then to the ECU, there's too much processing between the sensor and the ECU for it to be a usable signal. Aem is horrible, most of their products are low grade. They're great for gauges, but I'd never let it control my engine

[@Knownworldwide]

Yeah, I was trying the FIC as a super low budget for anyone watching but unfortunately it just won’t work with this setup. Appreciate you watching the video! Hope you decide to stick around.

[@LegitRaceCraft]

@@Knownworldwide you popped up on my feed last week and I sub'd, I'm trying to subscribe to as many is300 channels as I can just to see what others are doing to theirs on KZbin. I'm finishing up a huge project with my IS and finalizing a lot of small things, but it's mostly done.

@@LegitRaceCraft sweet! Your car boosted as well?

[@LegitRaceCraft]

@@Knownworldwide yes, it had what looked like a cxracing kit, I pulled all of that out. Now it has a precision 6266 on a cammed aristo head, my old IS block has forged internals now.

Hey man, I am curious if you are nearby. I am in Sonoma County. I am looking at picking up an IS300. I daily a B8 S4 and am looking at building an NA-T is300 for fun.

[@Knownworldwide]

I am not too far from you. What year IS300? I’d advise staying away from the 2001 year. Those are just a little different as far as wiring. They will work but I find the 2002-2005 have better support/more and less wiring issues to deal with.

[@Knownworldwide]

Don’t get me wrong though. 2001 is fine and it’s not the end of the world type of thing haha.

Also after researching alot before i buy mine it seems some companies make an extension harness but pretty much everyone re wires the harness to run into the car and get the ecu out of the engine bay but that is alot of work. Ive separated the driver side harness body and engine as the are weaved together sadly. Its alot of work

[@Knownworldwide]

Yeah. It’s pretty dumb how short the harness is but I am not ready to extend all that wiring just yet haha. I like wiring but it is a lot of work for sure! Thanks for watching btw!

[@MidwestMechanic]

@@Knownworldwide man it is alot but it's more just time consuming. I'm getting there but need more time🤣🤣

[@KTFCUTL]

Love all your videos man! Got an 01' IS300 I've had for 20+ years as a daily. Working on the suspension now and then moving towards the engine. Gonna turbo the ol' girl like you did. You plan on swapping the tranny? I know the autos are good up to 450. Have you had any issues with your transmission holding the power?

[@Knownworldwide]

Hey thanks for the support! That’s a long time with your car. Congrats on keeping it alive. I do plan on swapping the transmission to a manual. Most like a R154 unless a good deal on a AR5 comes around. Auto is holding up just fine so far. I am not making crazy power just yet though. I’m only around 4psi which at my altitude (sea level haha) I’m estimating around 235whp ish

[@vincejordan2715]

Where did you end up putting your EMU black module? Not sure if I want to extend the wires on mine or not. Did your harness end up fitting under the stock ecu plastic cover as well?

[@Knownworldwide]

I just have mine tucked up behind the shock tower near the brake master cylinder. I posted it up on the forum. It’s not ideal but it zip tied up and it’s pretty damn durable if you ask me. There is also an ECU temp monitor within the software. I will move it but it won’t be for awhile. I wish the made the wiring harness longer to at least reach into the cabin but oh well. The plug and play adapter does fit in the ECU box but with some creativity. Also there is no way you can fully screw the bolts back down. Mine are like halfway screwed down. The adapter is just too big.

[@landonphillips7013]

Just FYI your TPS voltage after you returned to closed throttle from open was 0.65v vs the initial 0.75v

[@Knownworldwide]

Thanks. I noticed that as well. However I double checked it again the next day after it warmed up and it stayed at 0.75v so I left it the same. So far it’s ok.

[@Knownworldwide]

Thanks for watching the video btw! Appreciate it.

[@landonphillips7013]

Thats odd. I wonder if the throttle blade/cable is dirty with carbon or something and if you let off quick it pushes past it if that makes sense. I know these have weird throttle bodies but I'm sure you'll know what I mean. Picking one up Saturday and wanna put a turbo on potentially but saw people doing the stock ECU and/or piggy back fuel/spark controller route and from someone with a Holley dominator on my 04 TT cobra it seemed very risky in my opinion with stock ecu. Then the piggy back seemed iffy because I really don't want a bunch of lights on on the dash. The black seems sick. Plug in and you got a standalone that retains all stock functions. At least I assume, unless you've noticed something else. @@Knownworldwide

[@Knownworldwide]

@@landonphillips7013 Nope doesn’t stick or anything. I double checked that. Not sure if you have checked out the channel in full yet but I did come from an AEM FIC/6 which is a piggyback fuel and ignition controller. It worked majority of the time and it’s what people have been using on these cars since they came out in the early 2000s, the Greddy emanage was also used. Stock computers actually worked when going WOT since it is just open loop pre determined amount of fueling and for the 4-5psi of boost most would run, AFRs would stay around 12-12.3 which is fine. I have never run this thing with the stock computer. Coming from the dominator, you should feel right at home with the emu black. Only difference maybe the VE table tuning instead of AFR targets. I also am familiar with the Dominator. Have just installed and tuned one on my buddies camaro. You may also want to look into Link ECU. That and the EMU are the only comps with stand alones that allow full factory gauge and HVAC functionality.

[@Knownworldwide]

@@landonphillips7013 what kind of power are you after?

[@chadborrows]

Quick question, I can’t seem to find any information on properly setting up the vvti solenoid to the emu black and how to let the software know it’s installed. Any ideas?

[@craziidevil4641]

Been watching all of your IS300 build videos and they have helped me out alot with my build. Doing the GT35 CX racing kit on my gs300 and ran into some problems. What exactly did you do with your o2 sensors and MAF sensor. I fitted my o2 sensors back into my downpipe except one, the bank 1 sensor 2. And as for my MAF sensor with it plugged in my car idles for about 2 seconds then shuts off, without it, it idles perfectly but starts to back fire at 3k rpms. Any help on this? Keep up the videos man, very helpful.

[@Knownworldwide]

Sweet! Thanks for watching bro, I appreciate the support. I should start by asking, what type of engine management are you running? What worked for me might not work for you since I was using the AEM FIC at the time. I have since changed to the EMU black now in this video.

[@craziidevil4641]

@@Knownworldwide Im on the stock ECU but I was thinking about getting the AEM FIC. I know another guy that did this kit on his IS on stock ECU, gonna ask him some questions and get back to you. Thanks

[@Knownworldwide]

@craziidevil4641 so if you are on the stock ECU you are going to have to clamp the MAF to a certain voltage. Otherwise you will continue to get MAF codes out of range and the car won’t rev past 3k As far as the O2 sensors, just put bank 1 and bank 2 UPSTREAM sensors into the CX down pipe. Leave the down stream sensors plugged in and zip tied up somewhere OR just unplug them completely OR buy O2 emulators (Karl long on FB used to make them) Your main problem is going to be the MAF sensor. You need to use a zener diode to clamp the MAF signal going to the ECU so that it doesn’t see voltage past 5v

[@Knownworldwide]

I also suggest a fuel return system if you don’t have one setup.

[@craziidevil4641]

@@Knownworldwide Sorry I am new to this, how would I go about clamping the MAF sensor? Would this be done using some sort of software?

I don’t. Heard good and bad thing s about them. I opted not to run one.

I got a similar throttle lock from Amazon and the car does become a bit jerky when trying to give a little gas from a dead stop. It doesn’t do it all the time and once the car is warmed up it runs and drives normally.
