Eddie 66 Report post Posted June 7, 2014 Does anyone know how much oil these engines take. Ive put in 5.5 litres and its still low. Quote Share this post Link to post Share on other sites
e30ftw 410 Report post Posted June 7, 2014 Around 6.5 - 7L Quote Share this post Link to post Share on other sites

Eddie 66 Report post Posted June 7, 2014 Tuning cut short. Got the basic tune tune sorted ie the drive ability but once I started to do some wot runs I started to get different afr on back to back runs. I need to check the pressure but I starting drink instead. 1 Quote Share this post Link to post Share on other sites

e30ftw 410 Report post Posted June 10, 2014 Wow not bad at all from a 2.0 . What changes did you need to do to get the S50 ITB's up and running in terms of engine management, or is this now on standalone? Quote Share this post Link to post Share on other sites
Eddie 66 Report post Posted June 10, 2014 Wow not bad at all from a 2.0 . What changes did you need to do to get the S50 ITB's up and running in terms of engine management, or is this now on standalone? I'm using a Link Atom. They are around $1000 mark. Its only controlling the inlet cam by changing the duty cycle based on engine temp,rpm and tps Quote Share this post Link to post Share on other sites
Eddie 66 Report post Posted June 10, 2014 (edited) For anyone interested this how we setup the Atom to control the inlet cam Edited June 10, 2014 by rot62 1 Quote Share this post Link to post Share on other sites
E30-323ti 66 Report post Posted June 11, 2014 Nice - did it take much time on the dyno to tune the VANOS? Presume it was done as a 'steady state' type of thing? Sorry if [OT] With using the Atom, are you running the Ign as 'Waste Spark' and the Fuel as Batch (3inj in 2 groups)? I was contemplating this for my 1JZ, but 'seemed' a massive downgrade from the sequential Ign and semi-seq fuel (2inj in 3 groups) it has stock. I presume the M54 would have been full seq' Ign + Fuel, not to mention the dual VANOS originally. [/OT] Quote Share this post Link to post Share on other sites
Allanw 1072 Report post Posted June 11, 2014 I'm liking this project I really like the M54 engine! It's also very cool that people like you share their projects on here! M54 Nerd info below: You're probably well aware of this, but that's not at all how the Vanos on an M54 is usually controlled. I find it quite interesting, so I'll bore some readers with sme info. The Standard M54 can vary the valve timing infinetly between the upper and lower limit, and uses pulse width modulation of the solenoids to alter the oil flow (pressure) to the vanos pistons to suit. It measures the amount of retard or advance using the cam position sensors, and adjusts PWM to get the reading it wants based on a table along the same lines as yours. It does it that way, because oil pressure affects the oil flow into the vanos, so when the oil is cold and thick, the amount of advance for a given PWM will be different to the same PWM with an operating temperature oil, which is a lot thinner (and of course, RPM can alter it too). I assume an aftermarket ECU capable of doing that is probably a lot more expensive and very complicated! I'm not up with the play of exactly what the full effects of the exhaust cam timing are, but I do know the M54 usually alters cam and ignition timing when the car is running cold, to heat up the cats faster (More overlap, later ignition etc), which is obvuoisly more about emmisions than anything else. I'm sure it has some input into performance at some point too. With really worn seals they can actually idle really rough sometimes as the ecu can't get the cams where it wants them under certain conditions.

Eddie 66 Report post Posted June 11, 2014 (edited) $2000 will get you a after market ecu that can place the cam timing were exactly where you want it. From what I have read and people I have spoken to is the exhaust is more for emissions. People have spent hours chasing exhaust cam Timing to only gain 5hp in the mid range To help us get around the oil temp effecting the pwm the ecu only starts controlling the cam after 40deg.

[/OT] Multipoint grouped and wasted spark using the factory coils I'm not looking for Max fuel economy , individual fuel trims or anything like that as this is just a low budget way of getting more flexible tuning over the factory ecu.

Eddie 66 Report post Posted June 11, 2014 (edited) By the way I ran the 520i up on the dyno before I removed the engine and it made 125hp at the wheels. It was completey stock at that time. So to get to a little over 160hp atw the mods I have made are Changed inlet to s50 itbs M50 exhaust link atom ecu Manual gearbox (was already in the car) Gull force 10 Which adds up to about a 30% gain in power which was more than I expected.

Who mentioned the dreaded 'e' word..... I was more curious to real word differences going from a fully Seq' EMS to a something 'less'. Probably more a perception thing I am guessing.... Obviously the improvements in power speak for themselves, bet it's a blast to drive. PS. No Vidi + No Dorty sounds track = It's not real Quote Share this post Link to post Share on other sites

No Vidi + No Dorty sounds track = It's not real Hahaha the e word Yes there gains for sequential vs batch but in this case not worth the extra cost. We run a sequential setup in our gtr and that allows us to increase the fuel for clyinders 5 & 6 due to the design of the factory manifold favouring these clyinders.
