Installed the Version 2 Helix TBE from gruppe-s about a month ago and the test pipe doesn't have the mechanical fix on it to keep the o2 sensor out of the main-stream so i calleed gruppe-s and they said it didnt need it anymore in the new version....Well after my dynoflash my cel is coming on and if i reset my ecu by removing the battery cable it comes back on after like 100 miles or driving hard... is this cause of the flash or do i still need the electronic fix (perrin).. i have heard of other people not needing the fix but wassup??

 

Its not the flash, you need the mechanical o2 fix or an o2 simulator.

 

they told me it didn't need one. I dont know if the perrin electronic fix will work on the IX or not. where can i get a easy to use o2 simulator??

 

Mechanical o2 fix part number "42009 Help" from your local auto parts store, can't go wrong for $3.00 have had it for 10K no cel
