Well this must have been a fluke situation. I've been re-tuning my VE tables in open loop SD and I have yet to run into any knock issues again.

I just recently installed a new intake on my C5 and hooked the laptop up on my drive to work to see how much my fuel trims are off and I noticed some odd things. There are occasions where I...

It appears to be okay. my 11.5:1 motor runs 21* timing up top on pump gas so you should be able to run 23. Either way make sure and monitor knock retard and pull timing if necessary.

I was able to get it sorted out and hot starting great by adding more airflow to the frictional airflow.

Raping the PE was an exaggeration on my part for explaining his method of leaning out the car. I was expecting a PE table similar to my original and for him to smooth out my MAF table to achieve the...

When its on open loop it is going strictly off of what it thinks the airflow is based on what you have set in you MAF caibration and pay no attention to the o2 sensors and makes no adjustment to the...

If you click on the photos it will open them up in photobucket and you can zoom in to see a full resolution version in detail. I can tell that isn't just where the car settled out because he didnt...

I have a LC-1 installed on the car and have tuned the VE and MAF up to this point with wbo2 afr % error up to this point. I decided to bring the car in to get the last of it finished up expecting...

Its because MAF calculations and VE calculations are two completely different ways of measuring expected airflow. You dialed in your VE table so everything was in line for those calculation but you...

Well I dropped off my vette last week to have the tune finished off, I'm capable of doing it myself it has just been tough to find the time plus I wanted to have the ignition timing worked on to find...

Yes those sound correct for stock values. I also found that I had airflow issues with warm starts and ended up having to add more frictional airflow too, but worry about if the time comes.

Are you...

So I've always seen when I start the car the STIT is 0 and then after 2-3 seconds it sky rocketed to over 2 g/s. I decided to give messing with the startup airflow initial another shot and worked my...

Took some logs this morning before work. I ran the idle airflow config just to get the cooler temps lined up and then once it was warm I shut it down and then tried warm starting the car with the...

Well I adjusted my startup off idle scalar and set it to 1, set the idle airflow decay to 0, set the airflow adder table to 2 g/s across the table, and airflow delay to 100 cam revolutions. I even...

With some guidance from a user over on the corvette forums I may have found something to attribute to my issue. Even though I can't seem to get help or insight on these forums I will document my...

Well I tried to play with the frictional airflow or the startup timing flare tables until I completely zeroed them out. This did absolutely nothing to fix my issue. It would be great to get someone...

I'm still trying to perfect my idle and startup and have gotten it almost squared away except for a warm startup flare where the rpm flares high and then falls really low and hunts back and forth...

Well, I am finally seeing a huge improvement in my hot starts and stalling. On a limb just making random changes and testing it out I found that the car does not like that much timing advance and it...

I have been following the idle tuning guide that Rinkrat456 posted here, I was planning on revisiting it again today and trying out the open loop idle outlined from it.

My corvette runs an...

Well I got up early this morning and have spent large amounts of time working on this today. I started out by adding the pcv and evap systems back into the car, I believe the pcv slightly helped my...

I reduced my idle timing in all maps to 24 degrees to see if by chance it wants less timing. No luck and it did seem slightly worse than running 28 degrees.

I've also been contemplating what could...

I decided to run the russk Idle-Airflow.cfg again this morning and my BRAF for the most part did not change. I then loaded those numbers into my working tune, at the same time I returned all follower...

I am having a lot of issues with my idle tuning my 1999 FRC Corvette and beating my head against a wall in frustration with it so I am looking for some more experienced advice.

I've tuned the VE...
