300hp N/A M52 project. Part8, first start

It's finally time to start this NA project engine for the first time. Getting the last details done, has been surprisingly slow process and this video has been in the works for half a year now.

You are blowing my mind. For a turbo setup on my s52 am I better off following you down the 45.1 ecu path or does the speeduino board make more sense. Was looking at VEMS but this is much more fun.

@@robertfontaine3650 ms45 isn't really good for turbo. Currently it can't run single o2 sensor and also it's limited to max ~500Nm torque. So from stock ecu's ms43 works much better for turbo use. But go with aftermarket ecu 👍

[@northernmaten7676]

hey pazzi, i want to ask you a question about the cylinder head of the m52tu/m54 what do you think about porting the exhaust ports on the head to match them to the size of the exhaust manifold because they are smaller and could choke the engine on higher rpms?

[@pazi88]

Yeah those are quite small. I did port those to be bigger on this project. But not sure if those need to be as big as the header ports (on aftermarket headers)

[@Ross_Trading]

So why did you switch the pulley size on the alternator?

[@pazi88]

The pulley on the ATI damper is slightly bigger than the pulley on the stock damper is. So it will overdrive the accesories. Which is otherwise ok, but alternator doesn't like extented high RPM usage like that. So it needs the underdrive pulley for durability.

[@team97octanos]

Congratulations! 🎉 Why stock ECU and no use speeduino or kdfi? ❤

[@pazi88]

I did tell about on few of the earlier videos. But I use ms45 mainly because it has proper torque modeling and because of that, it works well with 8hp.

[@gedas3419]

If I remember correctly drift guys put audi 3.0v6tdi pulley on bmw powersteering pump, because its way bigger, for drifting when bashing limiter and doing a lot lock to lock turning it also overheats. It prelongens the life span of pump. Only drawback is that pulley is big enough so power steering is a bit heavier on idle, but same on little throttle. You will not be idling on 700 anyway with high comp.

[@drewdavis239]

I have a lot of BMW's and a V6 TDI here. Im going to check it out later today. I already have some of the ecs underdrive pullys.

[@pazi88]

I will check it out. My plan was to use e60 ps pump, because it runs smaller pulley than older m5x engines. So the current pulley would be underdrive version for it

Is there any advantage of using MS45 instead of MS43?

[@pazi88]

@@bimmerstein1856 Well the biggest difference is the proper torque modeling that the ms45 and the capability to run the newer e6x CAN bus. Which ones are big benefit with 8hp. But otherwise, the only real benefit is the wideband sensors in ms45.1. But the ms45 also has limitations that ms43 doesn't, so for many setups, the ms43 is better option.

Cams where not changed in the calibration? Especially for the schricks that needs to be done. Ms45.1 calculates VE on the fly based on intake model and with dofferent cams you change that significantly.

Interesting, where can i get more info on this?

[@pazi88]

Not yet. That will come later when I get to the actual ECU tuning part. Now it was enough to just get the engine running. I also don't know excatly how to tune the VE calculation maps, so that will come later once I know more.

[@masonfitch6004]

Out of curiosity, why ms45 over ms43? Such an awesome car mate!

[@pazi88]

I did mention the reasons in the previous wiring part of this video series. But anyways, I use ms45.1 because of the dual wideband O2 sensors. And then also because the ms45 has torque modeling, which makes it feel way more modern than ms43. And that also helps with the 8hp-swap. Which also benefits from the fact that ms45 also supports more modern e60 CAN protocol.

[@jasperooms9210]

Very nice man! Keep it up!

[@motherphoque8843]

What hardware do you use to flash/read/write ECU?

[@pazi88]

This: www.ebay.com/itm/285716789174 But generally basic INPA-OBD cable works fine. But ms45 seems to be picky and needs that better one.

[@DriftDany]

bigger pulleys in engine its very good option , but maybe better use a bigger pulley in water pump and power steering ? , "more power" on engine and no problem with cavitation fluids and power steering oil dont overheat when you go high rpm . i searching bigger pulleys to power steering and also water pump , or you can use electric power steering , alternator 150 a from other bmw intake manifold from m50 ( b20 its fine trust me ;)) and use a bigger throttle body p&p form other bmw

[@pazi88]

Water pump technically already has bigger pulley. M52tu/m54 has smaller pulley there as single vanos ones and older have. So I did put on the bigger single vanos pulley there for water pump. I will also probaply swap to e60 ps pump that also runs smaller pulley. But still use the older bigger pulley there. So I don't need to waste money on fancy aftermarket pulleys for those.

[@DriftDany]

[@ttt69420]

Every single one up to and including the m54 e46.

[@DuffBeerLover]

Forgive me if i'm out of my lane here, but i believe that changing the stoichiometric AFR was a mistake. Since MS45.1 reads Lambda with no real interpretation to AFR you just made it target Lambda 0.67, thus making it run really rich in the clip with the good airmass meter. Instead compensate for E85 in your ron98, idle and cold start fuel maps and leave the stoich value at the stock 14.7 for MS to target Lambda 1.

[@pazi88]

Based on FR, that setting affects injected fuel amount and also some calculations that model the mass of the fuel and air moving in intake. It "should" work correctly like that and so it seems, with quick testing I have done. It doesn't affect lambda target. It still follows the set lambda target from the maps.

[@DuffBeerLover]

@@pazi88 I see, you clearly know more than me. I wish you good luck and I look forward to seeing your result!

[@pazi88]

@@DuffBeerLover Yeah, lets hope it works nicely. I did already swap in new OE MAF and it runs perfectly now, even without any further tuning. So it looks like that was the fault indeed and I can continue tweaking the maps to suit the engine.
