Actually, I think I figured it out. You just pick the regular "Boost Pressure" PID under Engine. The output appears the same as the CAN input.

I built my own CAN bus and hooked my pro-link up to the CAN outputs of my 30-0306 gauge. It reads the PSI as a channel correctly. However I cant seem to find a way to pump this into a gauge or a...

Thanks for the help with the math. I solved it, posting for anyone else. It was because of open loop gains for intake valve temp. The intake valve temp and injector tip temp is calculated to be...

Totally agree with you. Which is why I built all my own offset data. Holley was useless so I just logged and adjusted all my open loop over a few months until it was perfect.

Its an airflow calc issue, not fueling. My EQ is fine. What table would be referenced to show only the VE airflow calculation different based on the fuel composition %. To be clear, I'm not talking...

Also, either turn off your adaptive idle by setting the delay to 400, or log your PID for Idle Adapt Advance. Your spark is going up and down by 10 degrees at idle but we cant see why, which tells...

You have more airflow at 750 than you do at 1000 and 1250 in your VVE table. And almost as high as 1500. Do you have it that high intentionally? That will for sure fatten up your idle. Id...

Ive found their data to be pretty useless for any injector on a GM ECU. If you are a returnless style car, and you were well tuned before, go to your injector offset vs pressure table and find the...

So my VE is showing 10% less airflow on gas vs E85. I just switched back to 93 after tuning E85 for a while. MAF reading is still completely accurate. Here is the weird thing, its only under 3k...

I have the exact opposite problem. Mine goes 1.25 lean on hard decel. I'm open loop all the time also (intentional) so I have no O2 or fuel trims in the mix.

Your injector flow rate is off. I had the same problem with my 120lb ones. If you know your tune was solid on fueling before the swap, then you can calculate your proper injector flow rates based on...

If you turn the key to on but don?t start it, the fan should not run. If it does, it?s an electrical problem. Probably with the ground signal wire on the relay being grounded when it shouldn?t. If...

The instructions show the ability to add or subtract spark on the fly using the VCM Scanner controls. Current software version looks like now you can only subtract. Did the plus feature...

ARM would be really cool though. I have a Raspberry Pi running Windows 10 and that would make for a sweet little VCM scanner setup pumped into the video input on the headunit. I have that now but I...

I like to go back and forth between MAF and VVE a few times until they are both right. You can also do a quick histogram to compare your VVE vs MAF measurements of airflow. If they are both reading...

You can also datalog your injector pulse width and if your pulse width is bigger at 800 RPM than it is at 1000 then you know that your O2 readings are wrong and you?ve added too much fuel to try and...

How much overlap is in your new camshaft? If there?s a lot of overlap then know that you?re probably pulling some air in at idle during valve overlap and that?s affecting your O2 readings. Go off of...

Your virtual torque tables are still stock, way too low for your power being made. They need approx 50% increase, especially on your E85 torque table. Match your dyno results plus about 29% (25%...

You need to log your PCS 1 through 5 pressures and the trans slip. I have almost the same caprice except more cubes and more cam. Self tuned.

The main thing I really see weird with your TCC is...

I have the same converter and that is about all mine will do either. It overpowers the brakes after about 2500. My tune is right also. Ive seen it with +3k of slip, but never on a launch. Only on...

^^ Thank you sevinn! My data log seems to indicate this was the reason. The MPH and RPM of the mess ups match the settings. I will adjust and try again. Thanks

Sorry resurrect an old thread (proof I used the search function :)) but I'm having the same problem trying to dyno my 6L80 car. The shop wants to do a 4th gear pull but the car keeps downshifting...

I win the retard award of the year. It was just low on fluid. I didnt realize how much it would suck up into the TC and pump at first startup. Works fine now with more fluid:rolleyes:

I just rebuilt my 6L80 (proactively, no failure) using the Level 4 CDT kit, and also went with a 3200 CDT converter. The process was pretty painless with no grey area. However now I have no...
