Thank you N383 and robbyredneck. Good info. here. I hope others see this thread and find it helpfull as well.

I've got my AFX tucked away with velcro into a place where I can't see it. It's not...

Thanks Higgs, I will try that.
Two more questions: How can this be changed to lambda?
and What consequences are there when you change the stioch in the pcm?

This is my reason for looking into...

I really appreciate all the replies and suggestions, thanks guys.

I would be open to Lambda or AFR. However I would think one target number would be the same as the other?
I would love to have...

Stoich for the actual fuel in the tank is what? 14.52ish maybe for E-10 (if it's actually E-10)? :banghead:

Along with playing with SoundEngineers advice on tuning the Cylinder Charge Bias and...

That's what I'm thinking. I'm not finding one Bias Table that "fits all" here.

On a 110* - 115* summer day the ECT can get up to 192*- 195* ish and the IAT's are 3*-5* over ambient cruzing at...

What temp. thermostat are you running?

With the hot summers and cool winters and the large swings in outside temps here in AZ I'm thinking I might also need to run a warmer t-stat. I would really...

Scott,
Could you post up your "Bias Table" numbers before you moved the IAT sensor out of the engine bay?

Thank you for all the great information that you have shared here.

I too recently had the same issue with my LC1 after 18mos. of steady use. This week I was doing some tune tweeking logging data along with afr. Just crusing at a steady 70mph I would log an extreme...

What can I use for a filter to keep "Closed Loop" data off a MAF/AFR Error histogram.
On the table display we have "Fuel System Status" which tells you the second your in either Closed or Open...

Thanks Bill, but I'm looking for a filter as well to remove any closed loop data. Oh, yes I have a WB installed as well.
I only want to record the higher HZ range.
What sensor to use to build my...

Can anyone point me in the right direction?
I couldn't find a thread on "PE Tuning" after searching or in the "How-To" stickies that might have one with a filter to report when PE is active in open...

Don't forget about diff. gear ratios so you are comparing apples to apples. Shift points from a car with 2.73's will be different than a car with 3.42's.

I'm curious about this "transport delay" as well. (or perhaps you are referring to the "Closed Loop Intergrator Delay")
First I've seen it mentioned was in a previous post by Matt. Hopefully a...

Would you leave the PE "Delay RPM" setting at "0" permanently?

I can't say.
All I do know is I have had friends with Z06's, which come from GM without the TPM's activated, go ahead and have them activated after installing 4 sensors.
Why GM didn't include...

Find someone with a tech II to deactivate them for you. GM dealers, busy Corvette/F-body shops usually have one.

The fan shroud is still the stock one. It was sealed up pretty well, same as it was from the factory.

Even after we installed the DeWitts rad /trans cooler /engine oil cooler we made sure...

Thanks Bill.

Mine are so close to 0 all of the time now and now I think every car should look like that. I guess I should feel lucky.

Ok then, Aside from the warmer ECT there aren't any...

He does have a 160 in there! On top of that I helped him install a DeWitts with an engine oil cooler back in September to try to get the temps under control. Ever since he got that car back from the...

Take a look at this scan. His complaint was that his car was running warmer than normal when the temps are cooler outside. Not only his trims between Bank 1 and 2 are apart the car is running way...

A Follow up:

Well here we are more than 2 months later after my friend replaced the Bank 1 header gasket. Inspection of the old gasket showed no exhaust leak. We went ahead and replaced the gasket...

Thanks EC. We'll check it out, probably replace the gasket. :cheers:

Ever since a friend got his 02 Corvette back from a popular local Corvette shop after having a cam, AFR heads, and dyno tune done, he had overheating issues.
I used up 2 of my HPT credits to adjust...

Cool. Thanks Chris, I'll do that!

Bill, Here you go....
