As a result of doing a T5 to 700R4 swap I am also swapping ECMs (6397 ODB 1.5 to 7730) in order to allow the ECM to control the TCC on the 700R4. The new transmission is coupled to a 3.4L V6 removed from a 94 Firebird. I plan on using AZTY bin (92 Fbody 3.1 V6 and 700R4) with $88. I need to change the parameters (using Tuner Pro) in the bin to allow me to run DIS as opposed to a Dizzy. The wiring changes between ECM and ICM to do this is straight forward but the parameter values changes required in the bin are not. I have done some reading on this and it looks like I only need to change 3 parameters values in the bin (initial spark, max advance relative to TDC, max retard relative to TDC). Can I just use the values from the 6397 bin and input them in the 7730 bin?
The other changes I need to do are
-re-wire injectors for batch fire
-update AZTY bin with engine displacement and injector size.
-delete vats
I am aware that I will not require the cam and 24X sensors.
This engine with minor mods (shorty headers and 260H cam) has approx. 5000 miles since re-build and it ran very good with the 6397 ECM. Hopefully the above changes will get this engine started and allow me to tune VE and SA tables.
Replies welcomed if I have missed any other required changes.
