SilverBullet6.0 Posted August 9, 2009 Report Share Posted August 9, 2009 My ccsb has a LQ9 with bolt-ons and a TR224-112 cam. I tuned it last week and it has ran fine! Well tonite, I'm driving along doin 60 and I leftoff the throttle to slow down, but the truck keeps goin. It doesn't slow down. Same rpms, same speed. I can force it to slow down with the brakes. It feels like cruise control is on. It does this at slower speeds (35 in town) too. I have my base running airflow table dialed in and I tweaked my throttle follower/cracker tables. Any tips or advice? Quote Link to comment Share on other sites More sharing options...
SRT10KLLR Posted August 9, 2009 Report Share Posted August 9, 2009 Mine did that once right after a tuning session on the dyno and it turned out to be the throttle follower. I set it back to before the tune and everything went back to normal. It was a scary feeling though as I was coming to a red light and when I let off the truck kept going so I had to press hard on the brake pedal and it still wanted to go like when you power/foot brake(brake stall).

SilverBullet6.0 Posted August 10, 2009 Author Report Share Posted August 10, 2009 Man I've dialed in my base running airflow, played with the throttle follower and cracker tables with no improvement. Any other ideas? Quote Link to comment Share on other sites More sharing options...
chpspecial Posted August 11, 2009 Report Share Posted August 11, 2009 have you checked for vacuum leaks. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted August 11, 2009 Report Share Posted August 11, 2009 Did you mess with the TB at all? Quote Link to comment Share on other sites More sharing options...
Krambo Posted August 11, 2009 Report Share Posted August 11, 2009 He figured it out with the help of Zippy. He manually scaled down his Base Running Airflow. It still doesn't explain why it ran fine for a week and all of a sudden had issues. Some causes may have been additional tuning changes that altered the RAF or even a post MAF leak.

SilverBullet6.0 Posted August 11, 2009 Author Report Share Posted August 11, 2009 Yea, krambo, i dont mean to doubt your tuning how-to, but for some reason the idle-airflow.cfg didn't work for me??? the histograms gave me bigGer braf numbers than I actually needed. Also, the first week of driving this truck was mostly agressive driving. WOT runs and burn-outs, so the problem may have been there, but I didn't notice it lol. But I did tweak the ve table a lil, just didn't think about it messin with the braf table. But, the headache's over now! Thanks for all your help in tuning this truck!
