E40 should be used with either a manual trans ECM OS and the standalone controller, or, an auto trans ECM OS and what the factory used to control the trans, a T42. You can't make an auto trans ECM...

Wait, this is N/A? No boost? Why is there anything scaled in this tune at all? WTF is going on here.

You mean, people describing a thing that happens but then not posting the files that show the thing happening? Yep, happens all the time.

oh... you meant the transmission thing?

Did you miss the part about 'do not log MAF channels when MAF is supposed to be failed'?

What BCM code? That hasn't been mentioned before. You said it was only a U0101 in the ECM and no codes in any other module in the vehicle.

^^^ That right there? That's a rattle, not knock. Nothing changed in any of the data that would make it knock. Nothing.

You don't have knock at WOT also, you have a rattle that triggers...

Injectors get absolutely zero mention, nor why it looks like someone tried some form of scaling. This is going well, I expect positive results any minute now.

Yes, of course there will still be a Hz reading from the MAF when failed as long as it is still plugged in and still in the airstream. DO NOT log MAF-specific channels when you have failed the MAF in...

That is an excellent question that stands a better chance of being answered only if you follow the directions and post your tune file, and log file showing it doing the thing you say it does!

Your tune file, the one that produced that log. Like it tells you in the 'sticky' thread at the top of this very forum.

Short answer: RTFM. https://www.acdelcotds.com/subscriptions

Longer answer: Because the PCM needs to see the diagnostics run before it will use certain components and run the damn engine.

Actually, to have the best driveability, toss the MAF altogether and run it full time in speed density. Mine did nothing but cost power and mileage.

Start over with a stock file. That one is still too far gone, same as the last time you posted with this same issue. It's turbo, with a 1-bar MAP? And no SD operating system? And the injectors are......

Nope, setting that real low is for 'MAF-only'. Needs to be set higher than it will ever get to.

Get a 1lb rubber mallet, go over ev-ry-thing under the vehicle. tap tap tap Tap Tap Tap TAP TAP... stuff will resonate, some things will resonate up to a certain point then a tinkly rattle or buzz...

Yeah, the world would fall apart if GM did something so stupid as having twenty-two possible door module part numbers for a single vehicle, each of which requires its own bespoke calibration...
...

Uh, zeroed out what? Do not zero out the MAF table, that has nothing to do with failing the MAF and can create other problems. The tune file has the MAF failed correctly, with the exception of [ECM]...

Breaking my own rule here by offering help with a thread where the person didn't bother to include their tune/log files, and to not know that after 84 posts it shows you're a real slow learner, but...

I am not a wizard, but I am pretty sure there is more to it than just the addressing - there are all kinds of protocol things going on, prefixes that a module has to send before the others will...

A wizard, somebody who had the tools and know-how to do things like decode the datastream and dump the code out of and modify firmware in non-ECM/TCM modules, sure, one of those guys could probably,...

That's some kind of clanky mechanical noise the sensors are picking up, not something happening inside the cylinder.

One day to go before the post is edited to add the spam links...

You can start your own thread, it's free. Not likely to get a reply from other one-posters from seven and five years ago.

Wrong question... the E38 was used from 2006 all the way thru 2017 - different service numbers (the internal hardware), different applications/platforms, many many different throttle bodies that do...
