rough start problem

[BNRacing]

If you are experiencing a rough start or "popcorn" start, please contact your dealer (which for most of you is us) and you will be sent an update to resolve it. Make sure you include your VIN. For BNR, the best route would be to email or use the web form to create a data log ticket requesting the update. You can email datalogs@badnewsracing.net or go to badnewsracing.net/datalogs

Thanks

That's great that y'all have it fixed! Was it more issues with ECP or something different?

In a week or sp ill be sending in another datalog. I did load the latest tune that you sent( 3 days ago) and have put i think about 200miles on since then. I noticed that when i left work today i had it again.

If the tune is three days old and Jerry just posted the update tonight and to submit for updates, you may not even want to log but submit your VIN for a tune update and then proceed with trying to fine tune your tune through logging.

Thanks for the update Jerry.
I'll be sending in a log in a day or so. I've had an intermittent popcorn, rough idle. It'd be bad occasionally and then go away for awhile, thought it was the cold but it's gotten more regular in the last 2 weeks for some reason.

Good to hear there's a fix.

I got my updated tune, today (technically yesterday) and I still have popcorn start.issue tonight.

Ticket Sent. Thanks Jerry!

Finally updated the tune last night. Started up this morning and is running much, much smoother during a "cold" start. Thanks Jerry!

It's better but still doing it,

after I put on the intake, and injectors and a retune i'll see where it's at

I've sent my Logs in 2 times and every morning when I start the car i still get the above mentioned "Popcorn" idle.

I just flashed my updated tune a few days ago to fix the rough idle and it's still doing it...

 

[sx sonic]

Mine still rough aswell

 

[pacman552]

[rabbs88]

same here

I was having a rough start issue but only until the car warms up and the idle goes back down to normal. I was thinking it was adjusting itself on a cold start because I am usually not running 93 octane. Please someone correct me if I'm way off.

I also got the updated tune file but haven't loaded it yet, might hold off now.

Mine did good for a day or two. But now it is a rough start after every start, not just cold starts like before in the morning. Going to data log and email back to BNR.

Mine too. I heard on one of the threads once they're modded... they need the larger injectors to diver the richer blend of air properly. The smaller injectors cant deliver the qty needed at the exact time its needed to get a smooth start on modded cars. I can sorta believe it, but have no idea if it helps yet

That's during peak fuel demands at WOT, not at idle or during part throttle.

Bigger injectors have less control at idle because of their very low duty cycle %.
