I'm not a huge fan of the 1614299 ECM. It's not well supported. If it was my vehicle, I would upgrade the 16197427 PCM

The 16197427 PCM is normally used for either 4L60E or 4L80E, but can be set up for manual trans or non-electronic trans (700R4, TH350, TH400). The MTX-L AFR information can be configured for real time WBO2 into the 16197427 data log. The 16197427 is affordable and supported much better than the 1614299 ECM! I've made plug-n-play adapters to convert from the 1614299 ECM to 16197427 PCM.
