TriggerFish Posted July 15, 2013 Report Share Posted July 15, 2013 (edited) After the other thread about injector values I was curious as to how mine were. Anyway, I noticed something odd with the MAF. In the winter I replaced the MAF as it was giving bad readings, like the one shown below. On replacing the MAF (genuine BOSCH) it did improve the car in terms of smoothness, power delivery and economy. With it hooked up to INPA earlier I noticed it still had the out of range values. If the MAF is good, what else could be causing this to be out of range? I have run DIS tests before and I don't remember it saying anything was wrong apart from the disconnected EGR system. Could the EGR cause the MAF readings to be out? (I think when it was first replaced the EGR was still in place, but I'm not sure.) At idle, it sits around 4*0mg, which I thought was a bit high. To my knowledge, the EGR system isn't active at this rev range either, only opening when at higher cruising revs. Cheers Edited July 15, 2013 by TriggerFish Link to comment Share on other sites More sharing options...
bungers Posted July 15, 2013 Report Share Posted July 15, 2013 I haven't got a screenshot for that but what does your Analog 1 look like? Link to comment Share on other sites More sharing options...
TriggerFish Posted July 15, 2013 Author Report Share Posted July 15, 2013 (edited) Cheers, analog 1 is: That's with revs held at about 1.2k, same as in the first photo. Edited July 15, 2013 by TriggerFish Link to comment Share on other sites More sharing options...
JasonK Posted July 15, 2013 Report Share Posted July 15, 2013 (edited) When you replaced the MAF did you do a MAF and Lambda adaptation reset? BMW say it is necessary...although I've never swapped a MAF. It can be done in DIS in the adaptation program bit, where incidentally, it also recommends they are both run on MAF or Injector changes.EDIT: What version of INPA have you got? Mine is the same as Bungers'.... Edited July 15, 2013 by JasonKruys Link to comment Share on other sites More sharing options...
TriggerFish Posted July 15, 2013 Author Report Share Posted July 15, 2013 Ah, no, I didn't do the adaptation/reset. I'll try that tomorrow once the laptop's recharged. My understanding was it wasn't needed, but I'm happy to be proved wrong. (I might be thinking to do with the different MAF part numbers, I'm not sure.) INPA is version 3.01. Do they display differently/different things as I've got a DDE4.0 (M57), whereas you two will have DDE5.0 (M57N) Link to comment Share on other sites More sharing options...
bungers Posted July 15, 2013 Report Share Posted July 15, 2013 My screenshots were taken with version 5.0.2, I would imagine there's a difference between the DDE versions. Link to comment Share on other sites More sharing options...
TriggerFish Posted July 15, 2013 Author Report Share Posted July 15, 2013 Ah, I might have to update mine then - I thought it was the latest version in the public domain. Link to comment Share on other sites More sharing options...
JasonK Posted July 15, 2013 Report Share Posted July 15, 2013 Ahhh yes, possibly DDE version differences. As for the MAF, it is coding that is only required on some part numbers. That being said, in theory, the adaptations will adjust over time on their own. Maybe it needs a kick? Link to comment Share on other sites More sharing options...
TriggerFish Posted July 15, 2013 Author Report Share Posted July 15, 2013 I'd have hoped 7-8 months was long enough! It's also had the battery disconnected before while I've been working on other things. I'll try the DIS thing and report back though, and in the mean time INPA 5.0.6 and 6.4.3 are downloading, so hopefully one will upgrade nicely. Will test in a VM first before screwing up my working installation. Link to comment Share on other sites More sharing options...
bungers Posted July 15, 2013 Report Share Posted July 15, 2013 5.0.6 the latest then? I'll have to get that too. Let us know how you get on. Link to comment Share on other sites More sharing options...
TriggerFish Posted July 15, 2013 Author Report Share Posted July 15, 2013 (edited) Will do. I've seen one link for 6.4.3, which I'm trying too (although it might be mislabelled EDIBAS). I'll let you know/link here either way though Edit, looks like there's a version 9.*.* too. I'll give that a go too. Didn't realise how outdated mine was!

TriggerFish Posted July 16, 2013 Author Report Share Posted July 16, 2013 (edited) Looks promising so far: Update - it's installed and working. The version 9 seems to relate to the whole thing/package, it only installs INPA 4.something which is then updated to version 5. It's still newer than what I've got now, so I'll likely stick with it if I can find where the e46 lives! It's not under old, and I have no idea where else it would be.

Chimp Choker Posted July 17, 2013 Report Share Posted July 17, 2013 Ive seen a few imstalls that does not populate the f3 key. As long as the .ini file matches bungers you should be fineSent from my GT-N7100 using Tapatalk 4 Beta Link to comment Share on other sites More sharing options...
TriggerFish Posted July 17, 2013 Author Report Share Posted July 17, 2013 (edited) Awesome, updating the ini file fixed it - cheers! Before it had F10s on the f3 key, but commented out. //F3 = F10 //F3_Text = F10 //F3_ARCHIV = SGBD_F10 Been out and tested it, and it still looks the same as it does above, so maybe the bar formatting is down to the DDE as well? Still gave the same readings, and I've not found anything in DIS to reset the adaptions, but I did come across this, but I don't know if it'll work on my DDE4.0 Edited July 17, 2013 by TriggerFish Link to comment Share on other sites More sharing options...
bungers Posted July 17, 2013 Report Share Posted July 17, 2013 Glad you got it sorted! That's an interesting find, I've kept a copy for future reference. Don't suppose it'll hurt to try it on yours? TriggerFish 1 Link to comment Share on other sites More sharing options...
TriggerFish Posted July 17, 2013 Author Report Share Posted July 17, 2013 Same, thanks for the help I'll try on mine later (sun's super-heating the seats to painful temperatures atm!), but I don't think that option was there under special functions. I'll look and see though. Link to comment Share on other sites More sharing options...
Rich_D Posted July 18, 2013 Report Share Posted July 18, 2013 Mine has been feeling a little hesitant at low revs / off boost, so I decided to do some investigating with INPA My nominal air mass and actual air mass values are not the same, I know they are never completely identical, but the actual value is considerably higher than the nominal one, so does this mean my MAF is goosed!? Readings are approx: - Nominal = 356 mg/Hub - Actual = 485 mg/Hub The charge air pressure and rail pressure values are very similar for the nominal & actual readings, it's just the air mass one that's way out. It still drives well though and pulls like a train, just this occasional slight hestiation at low revs, with partial throttle... Link to comment Share on other sites More sharing options...

Rich_D Posted July 18, 2013 Report Share Posted July 18, 2013 Does sound that way Rich. Everything's back in the right place since your EGR etc clean the other day? Yeah, all back together as it should be, runs better if anything and pulls very well on full chat, it's just this low revs / part throttle hesitation, only very slight and not that noticeable. Might just leave it... Link to comment Share on other sites More sharing options...
JasonK Posted July 18, 2013 Report Share Posted July 18, 2013 Have you got DIS? I reckon doing the EGR adjustment program in DIS will cure that - it did mine. Set the value to +40 and see how it is. Note the value before you change it, so you can change it back - likely to be the default of 0. Sent from my Windows Phone 8X by HTC using Tapatalk - excuse typos and bad grammar!

I removed & cleaned the EGR recently, it was filthy, so this adjustment does sound plausible as now it's clean it's in a different state. Having said that the hesitation was there before I cleaned the EGR and was the reason for doing it Link to comment Share on other sites More sharing options...
Rich_D Posted July 19, 2013 Report Share Posted July 19, 2013 Found my discs, so going to try the DIS stuff that you mentioned, hopefully that will help, I pressume it's easy to do?
