WBO2-Tuning Spreadsheet

Possibly modify a factory 7.4 / Manual to 5.7 / Manual. I recommend doing a copy / paste of all $OD 5.7 fuel and spark tables into the 7.4 Manual .bin.

I know like there’s injector flow rates that are different what about like iac and stuff? Do you know like generally whag things would be different on a big block other than fuel and spark?

Using the TunerPro compare option, possibly compare BJKW 94 C-G-K Truck 7.4TBI 4l80.BIN vs. BJDR 94 C-G-K Truck 5.7TBI 4l80.BIN from the link above (7.4 vs. 5.7).

Possibly compare BHDC 94 C-G-K Truck 7.4TBI 5speed.BIN vs. BHDF 94 C-G-K Truck 7.4TBI 4l80.BIN (Manual vs. 4L80)

I've noticed some .bin files (like BMHK I posted above) have Altitude Spark Bias set to ZERO and most .bin files have Altitude Spark Bias set to 9.8. On your current .bin maybe try Altitude Spark Bias set to ZERO to see what happens to the odd spark advance numbers seen in data log.

Okay ill try the altitude spark bias and ill compare all those those bins to see what exactly changes too. Thank you
