B6612 ETC LIMITING on 2002 L18

[SHOGOR]

Anybody have a working performance calibration of B6612 for a 2002 L18? If I set all the fields to 100% the throttle hangs open for a second after I release the throttle. Not good.

I don't think B6612 is your problem. Have you changed Throttle Cracker or Follower settings? If you like, send me your tun file and I'll takea look.

No I didn't change the throttle cracker or follower, all stock settings. I just tried setting the B6612 to 100% in all fields. The throttle hangs open after you release it. Back to stock settings and it works fine. Should I try to zero out my stock settings for the cracker and follower decay delay rates in gear? I never thought to try it in park, If it works okay in park then it might be the decay delay. What do you think?

Why are you changing all the data points in B6612 to 100%? What are you trying to achieve?

B6612 limits throttle opening, it's used for torque management. I have no doubt that this is limiting performance. An 8.1 litre engine should fry the tires when you stab the throttle, this truck is lame.

B6612 should only be relevant to tire spin only if traction control is enabled. To find out if 6612 is causing problems, log throttle position-- if it goes to 100% when you put the pedal to the floor, 6612 isn't your problem.

b6612 is the problem same thing here throttle hangs open when 100% with out rasing it doesnt get full throttle

any one try b6609 and b6610 looks like they may help with traction control b1904 may help not sure. will test when i get my customers truck back now he has a feel for wot with the 8.1 he wants it.like having nos compared to how it did run

Has there been any updates on this? Looking to get more from a 8.1 myself.

Same question here. Or a more in depth one, why does setting it to 100% make it stick??

Setting B6612 table to 100% makes the throttle STICK (NOT hang) at anything over 70% TPS...but man does it add a ton of response. I have since set it back to the stock settings but boy I'd like that response back.
