BIN parameter compatibility

[damanx]

I suppose the best way to find out is to actually do it, but I thought I'd ask here first. My engine setup is as follows;

3.4l with Edelbrock intake, 4.3 throttle body and 4.3l injectors, Edelbrock long tube headers.

I initially started out using a 1228062 ecm, but then by suggestion, changed to a 1227747 ecm. From there, it just seemed that I could not get the engine to run as well as I have with the 1228062.

But the 7747 has a lot moreadjustability, and I want to go back to it.

I suspect that a lot of the problems I was encountering were related to several issues. The first being the spark latency table which accounts for the distributor size. If I recall correctly, the 4.3 distributor is larger than the 2.8 distributor. Other issues that may have affected the overall performance, I believe, are those that reference "delays" so to speak in regards to readings based on physical build of the engine/exhaust. Finally, I believe that the TPS values between the 2.8 throttle body and the 4.3l were another cause of issues. I've been focusing on these values mainly do to the fact that these alone seemed to have had the biggest affect on my tuning as I've found that using the values for the TPS positions from the 1227747 in place of the 2.8 TPS values in the 8062 ECM. These values also have affect on controlling the torgue converter lock/unlock, power enrichment, and a few others that I can not remember at the moment.

Now, there are lot more parameters in the 7747 versus the 8062, and as such, my question comes down to whether I can substitute 2.8 values where needed in the 7747 BIN where physical measurements are compensated for in the BIN. I.E. spark latency table, INT vs Air Flow is another of a few.

Like I previously stated, I could simply swap in the 7747 ECM and go using the emulator and answer my own questions, but I thought I'd ask here for more opinions. If I do this, I'll be using the ASDU bin which is a V8 bin, or more than likely, ATKX which is a 4.3 BIN.

OH!!!!!

With the 8062 BIN, "Initial Advance is 9.84 with "Spark Table Bias" set to 0. In the 7747 BIN, "Initial Advance is 0 with "Spark Table Bias set to 9.84"

I am thinking that I wont have to physically change the initial timing if I copy the initial/bias values from the 8062.

Thoughts?
