How to turbo BMW m50/m52 engine, part 7 - Megasquirt settings and first start.

Note! At about 13:30 I'm talking about wasted spark where all coils fire simultaneously. That is not true. There is 3 spark outputs, so only 2 coils fire simultaneously. The firing order in m50NV unit is "wrong" so that's why it uses same trigger angle setting as m52 unit.
Part 7 of the BMW e30 m50 turbo build. In this project we use Plug and Play Megasquirt called KDFI v1.4 to control the engine. The KDFI control unit is basically normal ms2 v3.0 unit so all basic Megasquirt stuff works with it. In this episode I will show how to connect the KDFI and how to do the settings to run the engine. These settings can used with other m50/m52 Megasquirt control units also. Not just KDFI. In the end we will start the car first time with the turbo and new injectors running e85. If you only want to see the start jump to 34:22.
Here are some tables and tune files I have made: drive.google.com/drive/folder...

Really liking your videos, keep them coming please! In the AFR table, since you're using e85, shouldn't it be in the 9's and 8's, or the table in reality is Lamba converted to gasoline AFR?

[@pazi88]

Yeah it's gasoline AFR. It can be changed to e85 AFR. But I have used to gasoline AFR numbers for so long that it's easier to understand what is going on using that. Yes the number is wrong, but immediately know is the mixture lean or rich if the number is over or under 14.7. I tried used e85 AFR numbers but I always had think what was the stoichiometric AFR and is it now too rich or lean etc.

[@wildnas5272]

How do you approach road tuning ...what's the first to tune and what's last when on the road...also thanks for the videos they're so frecking helpful man thabk you

[@pazi88]

First I start just with setting up everything like injector dead times and so on. Then comes quite tedious idle tuning and only after that I start road tuning the car. At first the ignition timing is quite low and I tune the VE map for desired AFR. Only after the fuel map is good, I will start adding timing. With normal pump gas you need to carefully listen for knock and with e85 it's mostly tuning for best hp, because it doesn't knock. But it can be difficult at road because with power car the speeds where car has 100% traction are quite high. So it basically needs dyno. Lastly I will tune the acceleration enticements, decelration and so on.

[@wildnas5272]

@@pazi88 okayy thanks.... I'm understanding it's best to limp it to a dyno and tune it after all that

[@SupaaSkunk]

Hi pazi, I have a question about the trigger wheel. I have a new controller KDFI m50nv and since I installed it, I have some problems with the settings I think ... The car worked very well before the conversion to megasquirt and the first time the engine was started there was a backfire in the air intake manifold with the following settings: - Spark Mode: Toothed Wheel - Ignition input capture: rising edge - spark output: going high - number of coils: wasted spark - trigger wheel arrangement: single wheel with missing tooth - trigger wheel teeth: 60 - missing teeth: 2 - tooth # 1 angle: 84 So I ended up changing the tooth # 1 angle value to 324 ° and I finally managed to start the engine. But after several other start-up tests, I had several detonations in the intake manifold. A first time when the ignition is switched on, and a second time when starting (which disconnects the idle actuator hose under the intake manifold and creates an air leak and accelerate my engine) So I thought to disable the priming pulse function to avoid injecting gasoline when I put the ignition knowing that MS2 automatically ignites the 6 spark plugs when it turns on (this partly solves the problem of detonations when I put the contact but not during the cranking) I think my problem comes from a leaky injector or an inlet valve that closes badly .. and with the wasted spark that causes a problem. I will make sure to replace the leaky injector and control the compressions of my cylinders, but .... I also noticed that on my recently purchased controller, the camshaft sensor plug seems to be connected to the car's original beam socket (here are the photos from the manual ibb.co/hwfLrU ibb.co/ftzDBU ). In this case is it possible for me to change the ignition mode to coils on plugs (i'm using OEM COP from my engine) and make my ignition is controlled by the trigger wheel and by the camshaft sensor? That way I can say goodbye to wasted spark and backfires in intake manifold ... Thanks to you.

[@pazi88]

Don't really know. The engine should work normally with the KDFI settings that it comes out of the box. That 324 degrees is correct setting, because the m50nv KDFI uses "wrong" ignition output order. Make sure that your KDFI and the coils get power simultaneously. If not, it can cause the problem. Also make sure that you have skip pulses set to something like 3. You should be able to use the cam input too, but the benefits are very minor from that. Only that you can have double the dwell time compared to the wasted spark setup.

[@snoobabs1]

Hey Pasi, sorry to ask here... wasn’t sure how best to contact. I’m Wiring Speeduino into my m50b25 e30... can I connect the coil packs and injectors directly? Or did you wire series resistors in too? From what Iv read, the coil packs are fine for direct to Speeduino and the injectors appear to be High-Z too, so fine for wiring direct. I just don’t want to assume and make expensive mistake. Thanks if you can give any advice. And your videos have been huge inspiration and help with this project, so thank you!

[@pazi88]

HighZ injectors are fine with speeduino. But if you are using stock m50 coils, you need separate igniters for those when using speeduino. BTW there would have been Plug and Play speeduino for m50 by me, which is much easier than wiring in universal speeduino: speeduino.com/forum/viewtopic.php?f=16&t=2638

Hi Pazi, I have a 1995 325ic that came with M50B25 and I have swapped to M52B28 but I am using the m50 original OBDI wire harness and m50 sensors, should I purchase the M50 ECU or the M52 ECU? thank you!!

If it's m50 OBDI harness you need an m50 ecu, the only difference in the ecu is the plug for the harness.

[@Bloodhawk759]

What differs from the Vanos KDFI, can you techinally use Vanos KDFI on a non vanos m50?

Only the wiring for vanos. But the vanos and non-vanos engines may have different pinout for ecu.

[@pazi88]

If you change the sensor to smaller tube, it will be capable of measuring less air. Probaply same amount as stock b20 maf. And you will need to recalculate the maf curve. But as hint, the stock bmw mafs don't work properly on boost side. You need to use the 540i maf before the turbo to make it work properly.

Hey man, how did you road tuned your ignition table. I am running m52b25 with 98octan gas is it ok to use your map but as you said, i should take 5.0 value off ,also for m52b28 ignition could be diferent? thanks!

[@pazi88]

Yes you can use it like that and it will be safe. But will not give you all the power that engine can give. When road tuning ignition with pump gas you have to listen for engine knocking. So you will need some knock headphones. Here is for example one that can use the original knock sensors: kzbin.info/www/bejne/gmaal6GFobyXl6s Also you could just run nylon pressure hose from engine block to hearing protectors to hear engine knock. If you can't or don't know how to do that, you have to get the car tuned by professional in dyno.

[@pazi88]

And the N/A pump gas tables I have in that folder are basically just maps made to work with speed density mode.

[@rudis1994]

wow really fast reply. Thank you i will dig on that.

[@rudis1994]

o also, i wanted to ask about wide band connection to kdfi. I already have wide band and controller separately, can i just run signal wire to kdfi box for 0-5v pin. And do you know is the kdfi box reading my stock narrow band sensors if they are plugged in stock harness?

[@pazi88]

rudis1994 Yes just run the 0-5 signal to kdfi and choose from tuner studio which wideband controller you have. It depends on your kdfi version if the narrow band sensors are wired. But those are basically useless if you have wideband.

[@brunocopetti2948]

Guys, can someone help me ? I'm having problems trying to "mirror" the rpm signal to the OEM rpm gauge. The RPM signal on MS3 works just fine, but not in the oem RPM gauge. All the instrument of the cluster are working 100% (I did the cluster test). The car is running perfectly, full sequential, smooth cold/hot start and idle. The only problem is that fckn rpm indicator that's not working. Can someone give me an idea about what could be the problem?

[@pazi88]

How hove wired in the tach and what settings you use? Did you remember to use jumper to enable tacho pullup?

[@bf3alltheway]

hi what would i need to do with the settings if i do have a cam sensor ?

[@pazi88]

Set the cam trigger settings for that. But the benefit will be really minor, because you would also need to use jumper wires to set the ignition outputs so that you can have sequential ignition. And then you lose some outputs that are for boost control, tacho etc..

[@bf3alltheway]

Pazi, I'm trying to figure out the single vanos control with KDFI 1.4. Im reading loads of mixed up comments, some say you just configure a NOS output switch, while others say you need relays and wiring done in order to make it work. Your brother's car is single vanos isn't it? How did you deal with vanos? Thanks!

[@pazi88]

Hi! First of all the brown e30 with m52 is mine and this m50 project is my brother's car. But in that my car the m52 KDFI 1.4 unit had the vanos working by default. No need to make any wiring or anything. The vanos solenoid is connected to IAC2 in KDFi unit. You can see this by going to tuner studio and check programmable outputs. it's enabled but there is some totally wrong settings in there. Here is settings from my car and it works perfectly: pazi88.kuvat.fi/kuvat/Projektikuvat/e30+xxx/mylly/vanos.png But that RPM setting is for 9.7mm lift / 240 degree intake cam. For stock cam use 4100 RPM limit. You can check if the vanos is ok, by applying those settings, burn them into controller, power cycle it, turn on ignition (don't start) then go to engine bay and give it some throttle by hand. You should hear faint clicking from vanos solenoid around that 30% throttle. You may need to disconnect the idle valve to be able to hear that. In my car those KDFI default settings burnt my vanos solenoid, so I had to change that. So if you don't hear it clicking, check the solenoid impedance. It should be around 30 ohms,

[@Chomersson]

Thanks for the quick reply. Yeah I like the brown one better :D I've got the same cams from m54b30 and m50b25nv right? The ignition timing and other maps you provide, are they for pump gas or e85? Anyway, I bought it as soon as you replied, any idea how long it takes to receive it? Do they send a tracking number or anything with it? Also, why dont you set it to activate from rpm 1000 to 5000? Why >30TPS instead? Just for testing purposes? To find out if it works? Thanks for your help once again and happy boosting :D

[@pazi88]

+kventis Maps are for e85 but yes I have those cams too. It took about two weeks to come. It depends if they have stock or not. They don't send tracking number automatically, but you can ask it. And yes that is also possible. But the m52 works according to rpm and heavy/light throttle. So that 30% tps is trying to imitate that light/heavy throttle situation. I tested different values, but that about 30% gave smoothest operation. rpm*tps based map would be best but that's only possible in ms3.

[@Chomersson]

Okay got it today and I'm just trying to figure out the wideband wiring, would grounding the GP2 and providing 0-5V input not be enough? Because I still want to keep the wideband gauge in the car that I got. Also I see you're using the JS7, TBL, and IAC2 ports, what for?

[@pazi88]

+kventis Yes that is enough. 0-5v input to oxy1 if you have standalone wideband unit. Then you have to choose which wideband you have in tuner studio. js7 is for launch control and iac2 for vanos.

hey, were did you get your injector specs?

[@pazi88]

From the internet using google. But the dead time I found for 630cc injectors is probably wrong.

[@rudis1994]

does it change anything if it is wrong?

[@pazi88]

rudis1994 No if you tune it with that setting. But then if you try to use the same VE map with different injectors for example, then you need to re-tune the VE map. And also if you change the number of squirts, then your AFR will change with wrong dead time.

Also the map senor setting needs to be changed and reduce the timing map something like 3 degrees. And regarding that m3 ITB, I wouldn't run that on boosted engine. It's really pain in the ass to get that tuned. You need to have combined alpha-n/speed density maps to get that working. That's because with ITB the vacuum area basically doesn't exists. So it will need alpha-n mode to work. But alpha-n doesn't work in boosted engine so you will need speed-density mode when the boost kicks in.

[@runesmDK]

I had to stop the video right before 16 minutes... you seriously misunderstood what wasted spark does. It's not all cylinders, and 120 degrees wrong will make it NOT run. Wasted spark fires cylinder PAIRS, 1-6, 2-5 and 3-4. Only one out of three pairs....

[@pazi88]

Yeah I know that the three spark outputs should be connected as pairs if done correctly. But while doing the video I couldn't think any other reason the engine runs with wrong trigger setting. There is no documentation about the KDFI which tell how everything is connected. But when I think that, the other reason would be that they have connected the spark outputs in wrong order and that's why it runs with wrong trigger setting. I will need to do some reverse engineering to see how the coil drivers are wired.
