If you haven't touched the tune in 5 months, I'd assume the problem does not inlie here. By the way, could you better describe the problem? What do you, "it runs like crap?" It could be something...

Still hanging at idle. Quit dying coming to a stop however. Maybe I need to bring back the RAF... I need to do a scan for you all to see.

See any problems w/ this '03 Tune for a H/C/I Z06 w/ an ETC TB?

More on this please. I've been having trouble tuning my dad's 2003 Z06 for a while now. It seems like when coming to a stop, it'll surge sometimes and other times, just fall on its face down to 300...

Bad ass. Thank you Bill.

VATS it is. Thank you again. :worship:

Check this out...
Thanks Bill

I have a question. Now that I added RTT to the '01, saved the file, and wrote the entire, the vehicle wont run. It turns over, cranks, and then immediately dies. What is the cause of this? I flashed...

Okay, what does load (g/cyl) do you usually read on a cammed 5.7 car? Usually anywhere from .76-.84 grams per cylinder. I'm having this problem where the loads are completely inaccurate for my...

Thank you Keith and Bill. I got the credit and have RT on the 2001! :yay:

How many credits are required to unlock Real Time for an '01 Silverado? I had RT unlocked for my 2000, and 2003 before I jumped over to the credit based system, and now I'm having trouble finding the...

Ohhh okay. I didn't realize the MAF would still read. :doh:
Easy question then.

Guys,

I think I'm still having the same problem. Below is my new tune and a sample log. The MAF is still gathering data. Why wont this baby drop into speed density?

Right now I'm waiting on some replacement front 02 sensors to show up, so I thought I'd put the car in OLSD. I turned off the MAF by setting the MAF Fail to 0. STFTs are also disabled. Would this or...

Those values are similar to what it had before, but it was running up past 19.0 A/F at partial throttle and idle. I was adding and adding VE and it didn't really even seem to richen up the mixture....

What should the IFR table read for green top 42# injectors? The vehicle is a 2003 Corvette Z06 with its stock fueling system.

Here is the current IFR table. I have a feeling it is off. Symptoms...

What is the ICL/ECL of your current cam as ground?

Is it possible that your IAC could possibly just go dead? We have a 2003 Z06 with the electronically controlled throttle body and I was doing some idle tuning yesterday morning. I played with the bi-...

If it wasn't entering PE, would it use the VE table?
Yes, I'll do that to ensure I am.

Thanks.

Not an injector problem then?
I'll try dialing in the VE a bit more and see if that helps. Glad to know it's not some stupid setting keeping it from entering PE.

I think I'm having a problem entering PE @ WOT. The vehicle is a 2003 Z06. Attached is its .bin file.

Car is in OLSD
PE enablers are set to 0
PE mult. is 1.21-1.25
PE should enter based off of...

So, to tune my truck I've always watched the IAC counts and played with the set screw until it help a decent idle. Then, adjusted the RAF accordingly.

On my dad's 03 Z06, I'm basically just...

When I zero out the Throttle Cracker table and cruise at say 40mph or lower, I get terrible surging where the RPMs drop to 500 and then shoot back up to desired RPM at that particular speed.

I'm...
