I did understand your question. And I responded appropriately. I showed you the table you need to modify to keep from setting the P1514 code. I'm sorry if you don't like my delivery. Doesn't make me...

Not really. The EPA compliance is designed to weed out exactly you. People that want to do nothing more than delete/defeat the emissions components. And most of the time it's unnecessary. You'll make...

With a larger cam, there is LESS vacuum, not more. The vacuum is LESS intense, not more.

If that was directed at me, after I quoted you a price you told me you were going to give it one more shot on your own.

Your tune and even your channel config says your $350 guy doesn't know what...

That makes no sense. If you know where it's at, what's the problem? That table has a good enough description you shouldn't be here asking why you're setting a P1514 if you know where it's at. You...

It's not trial and error. It's collect data, apply error correction, repeat.

You need to plot your trims and apply them to your VE. You aren't doing that. I can tell by the shape of the VE. Don't just multiply by a random percentage based on what you think you're seeing....

There are a few things going on any competent tuner would quickly recognize.

1, the VE is complete garbage. Anyone who think that's what a VE should look like doesn't know what they're doing.

First, if you've been doing research here, you think you would have read plenty of times, if you want help post a tune file and data log.

Second, if you set it up to tune in speed density you...

Yep. Why is there spray painting being done in the interior? OP also mentioned something about switches. Sounds like a cluster F.

While that all is sound advice I'm betting he doesn't have a thermal imager or a good scanner that can tell him if any door switches are open.

Pulling fuses is going to be his best bet as a DIY...

In addition to the above post, I would START by removing, disconnecting, unplugging any and all add-on wiring, systems, switches, etc. That would include aftermarket alarm systems, etc. That's the...

First, I should apologize. I should have followed up "you don't sound qualified" with "no offense" otherwise it sounded kinda jerky.

Do a search for "clamp on current probe" or "clamp on amp...

It does not sound like you are qualified to diagnose and repair this vehicle. There is a certain procedure for checking for an electrical draw. You need an amp clamp. A clamp on amp probe. The amount...

By the time you pay someone for the license for your PCM and for their time, you're pretty much at the price point of buying an MPVI3 or an RTD. I would think this is something most any professional...

Don't make me break out the crystal ball.......

I think you're right, partly. I think the 255 value is more like your master switch and the "ECT vs. Startup ECT" is exactly as it reads. At 25* F startup coolant temp you'll need to reach 149. But...

First question is, are you using the latest Beta?

Second question, do you have the .pdf of the E90 installation instructions? If you have the latest Beta and you did the "PCM replacement" as...

Have you checked fuel pressure? Could be bleeding off overnight. Not everything is fixable with the laptop. Need to cover the basics first.

Way too phat on start up. She's fatter than Oprah in the 90s. I'd pull some out of the startup IPW and the cold engine OL table.

That cam will definitely run better in SD. 100%

The surging around 800-1000 RPM is the jump in timing and in the VE table. Make your timing the same up to 12 or 1400 RPM and that will take that out of the equation. Then put it in SD and dial in...

I'd clean the connector pins and try again. I've never seen a GEN4 PCM "brick" during a normal write process, especially a write calibration. HPtuners even has a recovery mode in the case that...

You won't get any help in the lounge section. Try posting in the GEN5 section.

You need to post this in the GEN3 section. You'll get no traffic here.
