The cylinder airmass is steady at at the point where the fuel trims go from steady to positive 29% (5:36 in) and the only other thing that cahnges at that point is the timing goes from 19 to 16...

I have a 2013 SS with a manual trans and when on decel in neutral (clutch in or out) it will idle okay and then start surging. When it starts surging the fuel trims go to 30-ish positive just before...

I might be getting old and missing something, but this is a swap in a 91 Camaro RS that I tuned 6 years ago. It will now at times will dump out all the timing and labor pretty badly. The MAF, MAP,...

I have a shop that built a 2001 TA with heads and cam and full bolt-on's that was brought to me for a dyno calibration. Now the owner is complaining of the dash cutting off and then back on and...

I have a 2017 Jeep Wrangler with an Edelbrock supercharger in to get the cal dialed in. Is there any way to verify if the ECM has been unlocked or not? The ECM and TCM were supposedly sent to...

Hey All,

I have a 2002 Corvette OS in a 70 Chevelle and the client wants to go to a 4L80 swap. I can not locate any info besides a 2003 Vette

The OS is a 12221588 and the cal is attached. Any...

I am 99% sure I did a write entire but at this point anything is possible. I just got a second ECM and will see what she does. Thanks

Hey All,

I had a 98 SS come in with a single rear turbo setup. It still had the stock program in it and the stock injectors, MAF sensor and MAP sensor. Drove in finea nd the customer supplied his...

Raising the Max Fail worked like a champ. Thanks veee8!!

Drives great and makes great power.

I get the double and half for proper injector scaling but would that affect idle control?

As far as the Max Fail number, the stock is the 60. Suggestion on what to change it to?

Thanks.

Mike

Hey All,

I have a new body style 2007 truck at the shop with a 408 single turbo, not built here but in to get a cal. It is SD and using 85lb Fast injectors. Stock TB.

The issue I have is isle...

Hey All,

I have an 04 Vette that had a turbo setup on it and now NA. It has an HPT 3 bar OS and when I try to flash back to stock with the GM software it comes up with errors. Any resolution to...

Hey All,

I have a 2013 SRT8 Jeep with a Magnacharger in the shop. Previously I could see quite a few PID's including Pressure Ratio which are now gone with the latest update. Working with support...

I may have missed it but on the injector data, it says that the InjPW vs Fuel Mass must be inverse of the Fuel Mass vs InjPW table. How do you get the left column numbers to change to match the...

As the title suggests, can we change the VIN with 3.0? And if so the process.

Thanks

Is there a table to control the muffler bypass opening and closing? I did a search as well as looked through all the tables and did not see one. Just because I looked does not mean I did not miss it...

Hey All,

I have a customers car here and it is all pretty good start up and idle wise until you drive or hold up the idle and then it wants to stall after the throttle is let off. What I notice is...

Hey All,

I have a 66 Chevelle and here is the quick run down. 6.0 block, LS2 heads & intake. LS2 TB, LS3 injectors, 232/234 112 cam, Yank 3200 converter, LS3 MAF sensor, LS2 MAP sensor. The ECM is...

Ding ding. The more I looked into it, there is an issue with this BETA. There are two lines in both of my coast tables and they are actually tied somehow. I made the mistake of changing the lower...

Well, the idle spark timing control did change the timing the ramping up, so it is what is contributing to the issue. It was better but still doing it. I then went and looked at the idle spark...

I know that and have dome that before with another car. I was going to try it and see if that is what is making the timing go to 35 degrees as you hit 2-3 MPH. I have had cars as low as just 5...

I will try to zero out or lessen the over and under speed timing and see if that is it.

Thanks.

It is getting better and here is the latest tune and scan. At the end of the scan you can still see it does some slight surging once you go from idle to rolling idle and hit about 2-3 MPH.

You can...

Thanks for the inputs guys and will try it out. Like I had mentioned what you see is what I normally do and have zero issues, but they all have a smaller cam and little load change when going into...

I agree an airflow issue, and I have added and subtracted as much as 25% in 5% increments in the base airflow table and this current setting seems to be the best.

Hopefully someone can chime...
