koolrayz Posted May 23, 2007 Report Share Posted May 23, 2007 most of you know Brian has been posting about his Phantom TCS issue. I have also had this plague me for some time. Brian showed me a link to an old post where they talked about the P0121 map code causing trouble. Well That didnt sound right because I havent seen that code but it got me thinking about the code i do through all the time P0106 map. So went into engine diagnostics/ airflow/ mapsensor and found two tables that are the values for the high and low P0106 map. I lowered the values in the low table to 40% and NO MORE TCS LIGHT FLOATING ON AND OFF. I only lowered it 20% the first time and watched the TCS go off when the code threw so i lowered it to 40% and that was the end of it. I may take it down even further but this appears to be a geniune fix not a mask over that still allows the tcs to float in and out. A big thanks goes out to Brian on this one.

MrMeanGreen Posted May 23, 2007 Report Share Posted May 23, 2007 Weird, I have obviously extremely high MAP sensor readings and TCS, and have never had this probem. Maybe it's the later years? Quote Link to comment Share on other sites More sharing options...

It has a lot to do with the cam size. Since you have FI you have a smaller cam. The bigger cams cause vacuum issues that cause the TCS off light to pop on.

koolrayz Posted May 23, 2007 Author Report Share Posted May 23, 2007 For me it was all about low MAP pressure. Big cam 750rpm idle = no MAP pressure. You supercharger guys "blow" so you dont have the low pressure issues Brian and I do. LOL Quote Link to comment Share on other sites More sharing options...

MrMeanGreen Posted May 23, 2007 Report Share Posted May 23, 2007 I have a bigger cam, but small enough to make my TCS like me Good news, though. Ray, only 50#s? Quote Link to comment Share on other sites More sharing options...

smokinHawk1647545499 Posted May 23, 2007 Report Share Posted May 23, 2007 Ray what tuning software do you use? i fixed it once and for all as i removed TCS and ABS. Quote Link to comment Share on other sites More sharing options...
RedRocket1647545505 Posted May 23, 2007 Report Share Posted May 23, 2007 I have a big FI cam You get rid of the LS6 cam? Quote Link to comment Share on other sites More sharing options...
koolrayz Posted May 23, 2007 Author Report Share Posted May 23, 2007 Ray what tuning software do you use? i fixed it once and for all as i removed TCS and ABS. I use HPT. I would like to lose the TCS but I like ABS so im stuck with a 3 channel conversion or dealing with the TCS Quote Link to comment Share on other sites More sharing options...
