The stock tune you posted does not appear to be stock. What are these tunes from?

It would be nice to keep that loud exhaust note to. Once it falls below 800 rpm's it sounds like a sewing machine. LOL!

The LT4 generally pulls timing after a cold start to keep the rpm's up for a very brief time. I think it's less than thirty seconds.

The base idle does not pull timing.

Help us, help you! ...

Hold the start button down for six seconds to enter full run mode. Do NOT touch the brake or start the car. Flash the vehicle then hit the button to turn it off. Wait five seconds then hit the...

Have you tried Water-Wetter?

Thanks everyone for the post replies.

Yes........this is normal because it doesn't have built in drivers.

Double click on one of the devices that show the yellow exclamation. Select the driver tab and click update driver. Now, first...

Are you sure it's not waiting on you to respond to the "UAC" during those 3 hours? Did you disable "UAC"?

I've done several setups on Windows 8 systems and it would only load drivers from...

There are no built in drivers available in Windows 8 for the interface.

Connect to the internet, connect the interface, choose update driver from Windows Updates and it will load from the internet.

I don't think it's a good thing to run a cam with 9* overlap at only 700rpms...................14.79 STOICH would be too lean; wouldn't it?

........as viewed from the log. You can see idle at >1K rpm's after it rebounded from throttle closed and the air tables are >2.........the car lopes well at this time. The behavior can be observed...

as requested.....................I've enclosed the oem tune, a new tune and a log. What I'm observing is that when I let off the throttle the rpm's dip, then rebound to about 150-200 more than the...

It didn't have any effect at all. The Dynamic and MAF stayed the same.............the car sputters like SCHITTTT!!!!!!!!!!!!!

Gonna try this first.

..............little at a time. I don't want it to go kaboom..............LOL!

How does this FIAM look? Is it too much?

Which setting do I adjust for the Mass Air Flow(SAE) table?

My car's Dynamic and MAF flow almost exactly the same. Here's a snip from a log just captured. It only fluctuates minimally. The car sputters a lot at this setting but lopes really well though...

Can someone show me how to set the Dynamic Airflow and the Mass Air Flow to a minimum of 2.0 lb/min?

I've noticed that this cam has a natural lope when the airflow is above 1.900 lb/min. I can...

Issue #1: The idle doesn't fall smoothly to the desired idle setting. When going closed throttle, the idle will dip below the desired setting then bounce back up about 200rpm's higher than the...

Here are three logs from a cruise I just completed. My apologies, but I can't get WOT on the street. Traffic is somewhat congested right now. Cruise#3 has some brief WOT moments..............LOL!

?????????????

I've read that also. Most tuners disable LTFT's until throttle/idle is set, then tune WOT with LTFT's.

Me, I'm lost and seeking guidance here. There are some great people here. :-)

Here's a recent log............and my current tune. I think I got my tables mixed up. LTFT's are positive during cruising and flat at idle.

I'll check all the mechanicals. Thanks for the...

The idle still dips well below the desired idle when abruptly letting off the throttle or blipping it. It should fall gradually and settle at the desired limit.

Anyone have a LM2 WB for sale...

My car does this. Can you show me the table to correct? Can you provide a screen shot or values? Is it the "Closed Loop" tables?
