I am having the same issues. I have tried several cards to try and get it to work. Any Ideas??

Thanks for the info izaks!

Is there any logical reason why the throttle % in my logs would not go over 84%? I see that B0156 is a throttle area ratio vs. actual throttle position. Is there a...

I hooked up the EFIlive to my 2010 Silverado and made some logs on the dyno before and after a K&N cold air intake change. Just looking at some of the logs I had some basic questions I hoping to get...

Now that I look at it (and think about it) your right, I did go the wrong way.

Thanks for the input!

I see. Any ideas on the PID's?

I went out again and messed around with it. Loaded the stock program back in and just eased into the throttle until a higher RPM. I was trying to go from 2500 up,...

Tried logging those and no data. Also tried GM.gearsel and State00. With no luck.

Tried some more test with the trans in D and trying to hold it in gear with the DVT. No luck. Then tried to...

I saw those, but each of them are shown as unsupported PID's.

I started playing around with my truck tonight on the dyno and could not get it to stay in 4th gear. I don't have much experience with autos so I have been trying to read up as much as I can. Here...

Good information guys! Thanks for taking the time to put this together.

From the description of B4321 - "If the throttle position is greater than or equal to this value, or increasing by more than this value (each 12.5ms), then the throttle follower airflow is added."

That was one of the major changepoints when I started working on the idle. It was not having any "hanging idle" symptoms before this just a couple stalling/surging problems that we were trying to...

Thanks for the reply Shawn.

For B4307, I logged the MAF vs. ECT from a cold start and plugged it into the Des airflow table. I thought it seemed high, and I double checked the units were correct...

I was working on some idle issues with an 01 vette today. We having trouble with the RPM's hanging when pushing in the clutch while moving. I tried adjusting the Throttle Cracker Airflow {B4309}...

Getting specs on the cam right now. The plan is to supercharge this car down the road, so the stock TB and airbox are used. It also has the LS6 intake.

The motor has about 77K miles on it, but I...

I was real nervous about bumping up the timing, but I felt pretty confident in the checks we had done. I am just glad we were able to use a dyno to validate the results.

I did compare it to a...

I am working on a 01 Vette on a chassis dyno. Car has Patriot Heads, Cam, shorty headers, 42lb/hr injectors.

I did the autoVE and MAF tuning and everything was coming in good. When going into...

I'm helping out with a friends camaro trying to clean up his idle. We did a log the other day of mostly idling, but we did do a WOT run.

For the most part, the idle and in gear commanded timing...
