I've created a tune and scaled it by 30%. The startup doesn't seem that bad but I've got a few things that I'd like a bit of feedback on before I start shooting in the dark.

When it idles, the...

For anyone who may be as dumb as me in the future reading this thread, FIC advised me that the settings on their website are more than accurate enough to use without trying to modify for exact...

Thanks for the response. Your statement about the NA engine never seeing anything out of that range makes sense. When I look at the slope of the OEM data that did change, it's very similar to the...

I'm attempting to tune a family member's 2007 Z06 which was tuned by a shop that built the engine but could not get the driveability to a good place. The shop originally installed larger injectors...

Ya, I get it, I'm just trying to figure out what makes the most sense instead of arbitrarily replacing stuff. In my mind, an O2 sensor that was reading unburnt oxygen due to an air leak should...

Ok, Joe. I've got the car up in the air and ready to remove the headers but I'm not convinced I have an exhaust leak. I don't hear a leak, can't see a leak and can't feel a leak.

I'm wondering...

Thanks, Joe. Your pid file corrected my issue.

Question for O2 Logs... If a fuel trim goes negative, I thought that meant it was rich and positive was lean, therefore typically you would suspect...

I feel like the mistake is either in my MAP or in my PID, but I cannot find it.

Here's the issue: When I log, all of the numbers created in both...

That makes a large difference. Thanks for the formula!

58 to 44 is a 12.9% difference.

Can rail pressure affect Minimum Injector Pulse Width? I realize it's a measure of opening time, but it...

The tables in these spreadsheets are great, but don't the numbers only work if the Fuel Rail Pressure is 58 psi?

Is there a conversion possible to use LS3 injector data at a different Fuel Rail...

Thanks, Joe. I'll update that reference in the PID file.

Thanks, Joe. I didn't think about zipping.

I am looking for help with my first E38 VVE Tune.

Enlightening and Interesting.

I'll give the analog a shot.

Thanks!

Sorry, Dr. Mike - That definitely exceeds my capabilities as a PC user...

Help me understand the data transmission further, though. On the last page of the manual for the gauge, in the...

Yea, I'm not sure. I wired it up from this: https://forum.efilive.com/showthread.php?16636-Installing-an-AEM-Wide-Band-02-and-logging-afr/page2

I'm having a similar issue with the exact same sensor. I bought this with the desire to record serial data only to be disappointed when I opened the box and found that there weren't any wires for...

I doubt I'm much help, but as a reference - My LS1B won't record misfires as a code either. I have double checked the MIL settings and it's set to do it, but I'm not sure what the parameters are for...

Thanks, Joe.

I was able to get this updated in my tune but.... even after reading all of the threads on it, I still don't know what it does!

I have logged about 6 hours of data over the past...

That worked. I guess I had never saved then exited and opened back up before. I would save and close the window, then open the window back up.

I feel like there has to be something in the tune that is just too far out of the parameters of the engine dynamics that needs to be improved/changed before I can really get the Calc.VET procedure to...

Like these?
