* On some vehicles, there appears to be an incompatability between the "Thrasher" brand ECM chips and DirectScan. Some vehicles exhibit strange behaviors ranging from switching to "limp home" mode after running for 10+ minutes to causing the car to stutter to simply displaying erratic data on DirectScan during DFCO mode.
[[[[[[* Unfortunately, the company which developed the "Thrasher" brand ECM chips is no longer doing development on this chip.]]]]]]
* Remedies to avoid this problem have ranged from switching to other brand ECM chips to finding a version of the "Thrasher" brand ECM chips which do not exhibit these problems.
