There are plenty of 3.0i here. A friend of mine had one and struggled to sell it because it wasn't the diesel.

Its easily identified with the single droopy exhaust per side vs the quad on the 4.4 and nothing on the 3.0d.

I`ve found new description of parametr in wiki:
Quote:
Configuration exhaust gas temperatur sensors (c_conf_teg)

0: Automatic learning of EGT sensors
1: No EGT sensors
2: twin-scroll exhaust system with four EGT sensors
Do we have EGT sensor? If no, Does possible to install it and monitor by INPA or etc ?

They were planned and even the Pinout description is matching, but Ive never traced the inputs on the PCB to see if there is actual signal processing hardware behind the pins.

I think I got RR logger "road dyno" to work and loaded in a log on "engine speed" and "TPS" as I didnt get it to work live, but might be something wrong with my install or other factors (Works with loaded log on imperial but not metric).
I must have done something wrong or the E85 makes way reduced power, as I got 143hp @ 6300 and 129 lbs-ft (175 nm) @ 3500. (should have 170hp @ ~6300 and 210 nm @ 3500)
I have bumped injection and cant see that my injectors is the at the limit, but will go for 550cc anyways later on and just to try I had my latest tune with full-load exhaust on -105.

Do some friendly soul with more knowledge than me want to help?

HW mods
intake box removed -> sport intake filter
Full flow exhaust with ta-technix headers for m52(m54) to a 100cell cat and through a 3" exhaust with 2 straight through mufflers (one going 3" to 2x2,5")
other than that no other yet.

I'll give it a try.. for E85 always advance ignition 3 degrees, E85 takes more time for burning process, bigger Injectors is a must have so far i know, because injection amount is way more than ron 98.
First get injection and ignition right according to the used fuel, then you can mess around with tuning.(Having that not cleared, would always be a possible cause if the tuning steps don't give the results they should give)


Just as a hint, if your sport intake filter is located where the box was, it might be sucking in air that is pretty warmed up(separation plates don't help), which will take away ignition angle and with that, power. Try to get that filter under the driver's side headlight, there's a nice chamber where the fog light is.That is filled with flowing air from driving and it's separated from the engine, so fresh colder air is sucked in.
Another one, Exhaust at -105 maximises internal EGR funktion, best emissions, but not the best power.Try reducing stepwise and leave it were you feel it is best.
Then take on Intake, start at 120 and reduce stepwise.
You may also try out stock 325 Vanos entries.(Maybe a good starting point)

Not much but i hope it helps you a bit.

First to Daniel, Huge Admirer of your work and work ethic.. and what a great community!

Not sure if it's something worth posting to the tuning page or not; as it is more my own trouble shooting. I've completed a swap from an E83, MS45 m54. Converted to an MS43 with ms43 m54 harness, sensors etc. following all existing information. Flashed ECU with EWS module, all perfect. put the m54b30 tune on there as downloaded from you google drive.

And then my problems started. From what i can determine; the car runs well for a second or two and then proceeds to adjust the mixture, doing so by changing the timing as well as increasing the injector opening timing up to as high as 6ms. Needless to say; this kills the engine after approximately 2-3 minutes. I've replaced MAF, Plugs, tested ignition coils, replaced O2 sensors, in the tune removed post cat oxygen sensors and SAP as delete plate is already on motor and its exactly the same.

Im dumbfounded. Ive checked and rechecked all wiring. I've gone so far to heck the block is a 3L and I didnt just make a dumb mistake. I get 2 error messages, One for the electric fan not being connect and one for cruise control as far as i can tell from existing forum posts (125 & 0).

I'm not sure what would be causing the car to increase the injector timing. Any time advice would be appreciated.

Thanks.



lower C_N_TI_AD_ADD_MAX under your actual idle rpm (if you idle at 750rpm ,lower it 100rpm -650) ,see if it runs then. But you must find the culprit - mostly common - defective lambda (even if it not shows up on diagnose) or air leak before lambdas (may be at intake side or at exhaust manifold)

fuel or ignition maps change with sport mode?

two questions for the experienced guys:

1. for auto cars, does the MS43 change the the fuel or ignition maps the automatic cars when its on sport mode? Reason i'm asking is that after a recent tune that involved the wiki vanos map + throttle map+ some ignition and fuel adjustments my everlasting part throttle pinging problem in D is completely gone is sport and manual mode, cant find a logical reason except that something changes, as the car surges through the rev range much better in sport mode

2. why does the M54B30 engine generate the most power at part throttle? 50 to 60% opening creates the fastest rpm surge? more that that is useless? acutally feels slower

check out my throttle map and tell me what you think, i removed the correction values, good good results out of it above 2000 rpm, still have a hiccup from 1000 to 2000 rpm

I think that it is because the afr in this situation is in 14,7 and in full load is in 12 for protection.

Might should have mentioned its a b22
Okay, ill try my default vanos maps, and add some more fuel and add ignition to see if that makes it better or worse. Ive thought about lowering the intake to where the fog light is because of the hot air thats up there (after some spirited driving or just driving longer and touching the filter it is surely above 50C) its just tight because of the xenon box.

I did log my MAF readings and it went as high as 530 kg/h

Thankyou for the tips tuning is fun but time consuming, especially when I dont have as much knowledge as you or the others here.

Standard Maf Reading is around 510 kg/h for the b22 so 530 is quite good

I just realized that RR might have the dyno show whp/torque and not bhp/torque since its really close to 85% of what my engine should have, cant read anywhere that they stated either but if I make improvments from that its still a win for me.

Of course itís wheel power, those are street readings. Which settings did you use for virtual dyno? For me it didnít worked

I used imperial but loaded in a log of engine speed and TPS. I dont get it to work on metric at all which would be better for me the rest I didnt touch and if I change from imperial to metric I must restart the logger for anything in dyno tab to work again.

Ah you are using the dyno function of rr directly, didnít catched that immediately sorry. Would you send me a rr log to check it please?
