x2. Bump

I know this is a A6/T43 topic, but was hoping to find similarties with the A8/T87(a). TCM 5630 does not exsit in v5.0.4 for the A8... that is what was my confusion. I guess I need to email support....

Was this question ever answered? I see desired slip tables for AC OFF and DoD Enabled but nothing for "AC ON". Am I missing something here or are these tables just nonexistent in HPT? What is...

It is more than likely a MAF only tune. You will probably notice your Engine>Airflow>Dynamic>Dynamic Airflow High RPM Disable is set to something less than 500.

I suspect it is your O2's. B2 follows nicely with B1 but there are spots where B2 pegs rich while B1 still oscillates. That is why your STFT on B2 is a few factors higher. B2 averages 570mv and B1...

Any exhaust leaks? What's the status of your narrow band O2's? How old are they? B2S1 seems lazy.

To get this straight... you are forcing 14.12 in OL with EQ ratio of 1.000 and the car idles smooth and you are getting lambda 1.00 right? Are you having big STFT in other air flow regions or just...

Post a log and config. What is your "known good formula"? Is the formula based on a stoich being 14.2 or 14.7? Is you gauge set to a stoich AFR of 14.2 and does it agree with your log value.

And...

You probably need to update your software to the latest beta.

It is possible. We have an '03 1MB ECM (P59) running OS:12579405 from an Escalade. I've seen it done on 12587603 as well. Just wire the signal of the flex fuel senor to pin 56 on the blue connector. ...

I just fought this problem on my A6 G8 after a cam swap. The trans was basically calling for the downshift too late and would pull the motor down past idle. It would then give it timing to recover...

That's the GMVE value. Click the check box above the table to get %VE values.

The cross member has been heavily worked and we added a rack. We are running the f-body AC bracket on the passenger side, electric water pump, and the alternator and fuel pump with the six rib on...

I'll have to give you a raincheck... We are about to fire one up.

Well for future reference if anyone happens to find this thread in a search, I just used my J2534 tool and TIS2WEB ($55 for 2 days) to load the most recent calibration on my caddy PCM. I found a VIN...

Hopefully this is an easy question for someone to solve. I'm trying to piece together segments for a tune.

I'm starting with an '03 Caddy LQ9/4L60E/DBW 12576106 1mb pcm with 12593058 OS.

Got 2.23.523

That fixed it.

I'm at 2.23.446... which is not the latest Beta. I emailed support for 2.23.509 but I havent heard back yet.

I'm realativaly new to HPT so hopefully this is a bonehead thing I'm running across...

Im running 2.23 Beta. Under Transmission>Auto Shift Properties>General, the Power Downshift tables 6-5, 2-1,...
