my WB02 opened my eyes to how messed up my tune was. i started this hobby 7/03 with the realization you CANNOT significantly mod an engine and expect the stock tune to function. i tried the VAFPR, tried the FP adjustments etc etc etc. so 7747 goes in and tuning(inept) begins. VE was easiest. PE turned out 12/1 on dyno(dumb luck).
why do i have a stumble?
assumed it was air flow from right foot and induction system optimal? . AE invoke causes stumble. i added fuel to AE. thought it was better but i think warm temps allowed better atomization. added a accel coil/ hei module. it could now burn engine oil. zillion volts. so the rich AE could be burned. WB02 goes on. walla. 8/1 A/F on AE? 12.7/1 on PE. hmmm. seems i need less AE. i thought the BPW change affects AE. does not. thank you! now at 85% of stock 350 bin values and very nice. needs another 10% looking at my log this morning. without WB i would be lost in epom space. hours wasted tuning WO WB. but learning never ceases and learned a lot in process.

 

Yep.
Gotcha beat by 10 years, and still learning.

 

now i can run red lights !
