Engine running rich

**Jbonly21** · 04-23-2019, 10:38 PM

I know I probably need some tunings or Dme reprogramming. Just need some pointers. I swap out my m54 525i for a 530i , with some eBay headers, with straight pipes and a muffler. Everything else is from the 525i. The O2 s are plugged in, but the car is running too rich. Need help. Thanks

The MAF + Housing must match the DME.
Does it (both from 530i)?

When does it run rich?
Only on WOT or all the time?

**Jbonly21** · 04-24-2019, 08:21 AM

Yes, only on WOT, I get a cloud of smoke also.

Injectors are the B30 or the B25 ones? Your maps would be all over the place. Yopu need to get tuned ASAP, that "cloud of smoke" could also be carbon deposits dislodging on hard detonation and that's gonna be a showstopper for the rings and your engine.

Yeah, B30 intake manifold. Do I need to run a B30 map, or custom maps?

possibly just copy the injection time maps for the injectors. M54B25 uses different injectors so pulse times and all would be way off. I think (think) they operate at the same pressure so just copying the maps from a B30 ecu will do, and if you can log data with test0 see how's your adaptive & multiplicative figures to further refine it, or just scavenge all your donor parts (maf, and related engine peripherics) or get a remote tune for B30 swap, I'm confident there'd be plenty of guys that can fix you over a laptop with internet access and a K+D Can cable

Thanks for the input, and if there’s anyone on the forum that can hook me up with this, or remapping please let me know. I am in LA.

I don't think they're allowed to offer services and products as per forum rules. I can mention that I've hired DUDMD who's a forum member here and he's been great. Imagine that he got me fized and I'm halfaway across the world so I imagine he can and will fix your issues. Fast, no BS no nonsense, reasonably priced. Doesn't get any better than that.

That's what I'd do on I6s. Me7.2 is a whole different ballpark. Then again, OP might be cozy around wrenching only, not coding. A lot of very skilled wrenches aren't fond of wires/computers.

Its the same for us computer nerds we usually dont like wrenching

at any point if OP is so inclined the data is free for public consumption otherwise if OP does not want to computer tune himself I highly recommend the fellow you did

he is personable quick to reply and handles business as expected

Thanks guys, and you are right. Not a fan of coding and stuff, more off a wrench guy. I have a buddy that is going to remap to a B30 software on Friday. Drove the car today, about 15 miles, no wot speed. Still smokes at the end of the drive. I am going to park it tell the updates is done.

Smoke scented like sweet and barbecueish or stingy like an old spark plug?

**Jbonly21** · 04-24-2019, 08:16 PM

Black smells like fuel smoke.

then it's rich rich rich, since you must have cats in place
did you do a plug reading?

No, haven’t had time to check things out, maybe after work today I will.

Just took a quick look to see what I could find, and man it’s running really rich.
Spark plugs are covered in fuel , these are new plugs.

And these 02 live data are all over the place

Yup, almost drowning in fuel

**Jbonly21** · 05-06-2019, 06:40 PM

Update, still haven’t been able to update my dme, I am running the car with b30 manifold, throttle body, air hose, and maf. With my b25 injectors. I also have headers. I get a little bit off black smoke after about 30 minutes off driving. Does anyone with headers have smoke issues?

I think it may be better if you install the B30 injectors.

Installed the B30 injectors, and it’s still running rich. I might have to do the flashing myself. It’s the a diy, for beginners?

It's like intermediate, not super easy but not rocket science either. At this point it might be wise to contact a remote tuner and see if he can write your ECU with the B30 maps with the setup you've assembled. I could recommend DUDMD (member here) who has tuned me remotely for applications I couldn't do myself.

Thanks for the help so far, I already messaged him.
