Greg i pulled my motor at 17 and rebuilt the motor and transmission. It was a lot of work (and failure), but in the end i did it, thanks to your videos and many others. Today will be my first drive back in it. I love watching your videos, yiu helped me understand this car a lot more and im very grateful. Thank you greg the miata dad ❤️

[@JamieBainbridge]

I love how methodical and scientific you are. I work in open source software and you're the guy doing an "open source" turbo Miata build. All the success and failure on display. This is the stuff nobody else shows so they can charge hundreds of dollars for a morning of dyno tuning someone else's car for $$$.

Love the tuning videos Craig! Just installed my MS3 last month and I’m in the middle of installing my turbo so I’m trying to learn as much as I can about boost tuning or just tuning in general. I learn so much from your videos! 🤘

[@rjcraft18]

Please upload more when you can. We love your channel and, most of all, the miata dad!

[@maximilianstobinski2469]

You could go to water or water methanol injection for limiting peak pressure aswell...(rising the thermal capacity of your gas whilst maintaining good timing) if you have too little timing your exhaust temperature will rise... be aware of your turbo heat tolerances! (Honestly not sure if you are running a exhaust temperature sensor on your car tbh)

[@skylinesandro]

theres a few people who have done oversized head studs (12mm or 1/2") with larger washers to increase clamping force on the head. I have been considering it since my head lifts as well on occasion. I've also seen various custom head gasket setups, full copper, fire ring, etc.

[@LUCKIPUP]

probably a good idea

[@wibuwe]

Recently sold my NA but this is great info for all who want to use MS regardless of application. I plan to use MS in the future so this is very uncommon info that was needed.

[@nnowakowski07]

I’ve been particularly interested in this video arriving. My own BP had similar symptoms at 400hp and 20psi. 3 headgaskets swapped, each time seeing different machine shops and each time the machine shops were baffled since the head pressure tested well and was planed flat. I eventually concluded there must be a hairline crack in the block or something and swapped another motor in and turned the boost down. I was hoping this can video would give the final answer to my own mystery… alas… we appear to both still be at a loss. 😅 It’s got to be cylinder pressure from our particular builds though. I just don’t know why my motor couldn’t seem to maintain it when others apparently could. Although my motor ran for 20k miles fine before the 3 head gaskets (which were 15miles each before symptoms arose). 🤷🏼‍♂️

[@FierceMotorworks]

Thanks for making these in-depth videos about tuning and lessons learned. They are super detailed and appreciated!

Saw it till the end. Sure i have to watch it again to understand some things. But love the content. Greetings from Greece.

[@travmason]

Handy tip for shielded wiring sensors (knock in this case, VR or Hall sensors also good to shield). Find some microphone cable from a music shop. Nicely shielded and cable is made tough.

[@geraldjustprojects]

hey just wanted to let you know thats not how how you should wire the knock sensor. the shield and sensor ground to join together at the ecu side. the shield goes around both wires wires. and on the sensor side the shield doesn't connect to anything. only the ground signal goes to the knock sensor. seems a bit strage but thats how ground shield should work.

[@DaltonWeems-i6p]

As someone who is wiring in a oil pressure switch to a ms3 this video hits me good thanks greg

[@thundercrowz]

A better cam and a port and polish will probably allow you to lower the boost and make more power with less cylinder pressure.

[@chriskellogg7880]

Excellent video, and well timed. These subjects were all on my mind for my project. Thanks!

[@chadl.981]

You did a really excellent presentation on knock sensor setup. I also did not realize you could configure boost by gear ramps with those tables. I'll have to try that out. The method I use to dial the knock threshold percentage is, take a log of "knock-in" in say second gear, and gradually increase RPM's and load all the way to redline. Take those values and plug them into the table for knock threshold. In my mind, this method gives you an accurate level of natural engine noise at any given RPM. One dialed, any knock-in levels 6-10% above this curve could be considered as real knock.

[@estewar03]

[@Friendsofdonr]

Appreciate the knock setup! I am happy to see you're looking at peak cyl pressures. Now I need to get my tune setup for knock, for some reason last time I looked (ms3pro) I didnt see the bandpass and time (btdc/atdc), which is likely why my stuff never worked right (🤣)

Great timing Greg, I've been working on getting knock control working on my NA6 vvt forged motor with 6258. Just an FYI the knock window start settings are in BTDC not ATDC so you want +6 not -6, with these settings you are actually measuring 6 atdc to 32 atdc.

[@juliank911]

Excellent content as usual, I don't even have a Miata anymore or even a turbo car yet I always watch your videos because of the quality of information. Great work!

[@nucleart0aster]

Just fyi. Haltech elite 1500 can do boost by rpm X gear table. It also has awesome protection strategies for your engine. I would also recommend a exhaust pressure sensor. You might have way too much back pressure and might need a bigger rear housing for your turbo. To make your system more efficient.

[@TheCarPassionChannel]

I am certain eMAP is off the charts on this setup

[@nucleart0aster]

@@TheCarPassionChannel please keep us updated on your progress. i'm planing to go turbo on my NB1 (bp4w) but goal will be no more than 300whp. getting started on the bottom end upgrades soon. hopefully i will keep my 6speed alive at that power level. i did get a sprung clutch to make its life easier. i also want the best response i can get as its a circuit car but also dont want to be blowing gaskets (ever). plan is 10:1 84mm pistons on 50/50 e85 / petrol blend. and a turbo big enough for 350 but tunned to 300whp. maybe i can have the extra 50hp on a steering wheel button for use now and then 🤣

[@banzairx7]

Great video and perfect timing. I'm about to set up the knock sensor on a 323GTX using an MS Evo pro. This video just took out a ton of guess work for me.

[@lockjawjak]

Sounds like you need a haltech ;) Another benefit of coolant pressure sensor is to measure if coolant pressure goes too low, aka coolant leak. I nearly blew and engine after the heater tap hose broke off due to the plastic deteriorating and of course the coolant temp sensor will not pick up an engine overheat until much later if there is no coolant in the engine :/

[@Rdsw-techBlogspot]

Hello from puerto rico, i bought a miata for follow your projects. thanks

[@elijaah81]

The dyno shart is GNARLY. Start hitting boost at 3k or so and it HITS at 4k while holding flat to high 7k. Its beautiful

[@TheCarPassionChannel]

That's EFR life!!

[@martinrodger9565]

I think Miata OE knock sensor is a resonant sensor so only outputs a voltage signal for a set OE frequency. a large voltage jump from a known baseline could be knock. But it’s prone to error. Non resonant “wideband” style sensor will allow you to test against frequency and set a suitable window for your engine. Then set suitable thresholds.

[@sonofthehill1320]

You should talk with Pat. You know that my car runs 11's all day long for years. Come on out, money races July 4th and 5th, with Wally's on the 5th. I have also lifted my head without blowing the gasket before. My new motor was machined on better machines and I haven't seen evidence of it yet. Just ARP high boost studs and Mazda gasket.

[@therobertshouse]

Another great post and love the nerding out on Megasquirt and Tunerstudio stuff! Question, for boost by gear, how does MS "know" what gear the car is in?

[@TheCarPassionChannel]

@@therobertshouse It's a calculation based on comparing engine RPM to driveshaft RPM (or rear wheel speed depending on where your sensor is), and you input the gear ratios into Tuner Studio. So it knows if driveshaft RPM is 3000, and engine RPM is 3000, it's the 1.000:1 gear which is 5th in mine

[@COSMICKID1235]

So hypothetically, could you benefit from the boost ramping in 2nd and 3rd gear by setting a slightly higher boost level >5k rpm? Im sure the benefits would be extremely little, but if you're already min-maxing this setup, maybe there's a tiny bit more to gain there?

[@ninokri]

How is the basic PID control serving you? What's the amount of oscillation in target vs actual pressure that you get? P.S. TPS going to 60% while 5V spliced together with CPS is either voltage drop on your 5V line (probably damaged wiring), or you picked the signal and not 5V line from TPS.

[@ks1622]

Very informative video!

[@wual.]

Do you think these tuning solutions are going to be as reliable as addressing the hardware? Or do you think it’s just acting as a bandaid for an overall bigger issue? I wanna hear your thoughts before I decide to pull the motor, as I’m dealing with something similar myself. 😭

[@EkClassics]

Funny that I get Nissan ads on your Miata content... Mazda, missing the opportunity.

[@khawajadotd]

Doesn't the cooling system naturally hit max pressure anyway, as it heats up and some of the water boils? My understanding was that the overflow tank always fills up a little bit while the engine is hot, and then lets that coolant back in once the engine cools down.

[@ericchambers9023]

Great video! Question though, isn't the cooling system always going to reach the radiator cap pressure under normal operation? Wouldn't that trigger your ECU into limp mode all of the time? Maybe set the trigger pressure to just above the cap pressure?

[@TheCarPassionChannel]

No, the reason for the cap rating is so that if too much pressure builds in the system, it pushes coolant into the overflow tank. Under normal conditions it should not do this (I've seen a max of about 12psi so far during normal driving and some pulls). If I life the head again (hopefully not) I will be able to see how high the pressure goes, maybe it's well above the cap rating like 20-25psi, in that case I might set the failsafe up at a higher pressure.

[@bandwagon240]

I got lost after 5:56 when your dog walked in. Administer pats from a fellow Graeg plz. Maybe try a different fuel, I'm running 27:1 compression @ 22psi on my 3.0L 4cyl. 40 octane is what I run, but I don't quite get the high numbers you do.

On the knock sensor, doesn't it not make sense to only listen for knock between -6 to 26, as every cylinder will be firing or knocking at a different crank angle based on firing order. Crank angle is only based on cyl 1 no?

[@afhostie]

30:00 Does that setting still work, only listening during a window around TDC, when you're only using one knock sensor?

[@TheCarPassionChannel]

My understanding is that it listens during that window, for each of the 4 cylinders, on the combustion cycle. So it's technically got 4 "listening windows" per engine cycle, a total of 104° (26° x4) out of the 720° cycle. So I'd imagine that still helps keep the signal cleaner
