Discussion: ABS, Advancetrac, Line-Lock etc

[BMR Tech]

Even when I "disable" everything by holding the button....then go WOT from like 60mph with no tire spin, the Advancetrac freaks out too.

My car would fall on its face when launching or doing a burnout with dr,the problem was mostly clutch protection,but i found out recentley that using launch control even with trac and advance trac off,that trac control still intervenes.

Have u looked at the wheel sensors why driving,to make sure they are all reading the same mph.

All of my issues started after I installed the 9" IRS Kit with 3.00 gears and the Whipple Flare tool.

Not sure if that is related.....but I cannot find an issue anywhere.

I was thinking maybe I damaged something...but I am not sure it would only be at WOT if something was damaged.

I have not.

Do you log that with SCT?

 

[Tommy V]

Im not sure if u can sct but u might.I use a snap on modis,but any scan tool that reads data and has abs software should.Do u have any abs codes or trac codes?.

 

[BMR Tech]

No codes

I dont think u damaged anything for the same reason u stated,does the whipple flare tool have software updates,and is that a common gear size?

I was the first person to go outside of the OEM Gear range on the S550.

The lowest numerical Ford option is 3.15. I know they had to put extra effort into my deal to get it to work right.

Oh ok,that makes sense,the computer is not making sense of whats going on.Most likley its tune related.

Hey Kelly,i would definitely check them wheel sensors and make sure they jive with what your speedo is reading.If they are not matching it will freak the trac control out.

I have no problem launching , when it hooks the 60 foot is real good ..What I'm having problems with is the burn out ..trac and advance trac off .. shifter in S , paddle shift in first gear.. Motor doesn't want to go over 5k , if I hold it a long time with my foot to the floor it will finely get to 7k , paddle shift to 2 gear and it bogs right back to 5k ..The trac and advance trac has to be causing the problem somehow ..Hell i'm in the water and I have a blower with 580 foot pounds of TQ at 5k it should be able to do a burn out .. :( This only happens at the track , on the street it just a big smoke show in the first 4 gears .. I haven't tried pulling the fuel yet but it's on my list ..

No way to activate the line lock externally that I can find. Looks like its all strategy controlled. I am almost done with our new add on line lock though. Just finishing up testing now. I had hoped we were gonna be able to use the factory stuff, but no luck.

Is there an output shaft speed sensor on the 6r80?

The one on my MT-82 was giving me fits trying to make dyno pulls after my rear ABS sensors were damaged.
