Hey guys,
Hoping I can get another set of eyes on my FAST A/F targets and Spark table
Relevant specs (let me know if I missed anyting):
445 stroker (built by Barry at Survival)
(ported) Edelbrock Performer RPM top end
Fast XFI Sportsman EFI system
Fast Dual Sync Distributor
Cam specs: only known to Barry
Dyno'd at 495 hp and 541 ft. lbs.
TKO 600 with .64 OD
9" with 3.70's
I know cam specs are important but guessing that a ~500 hp 445 stroker would have a reasonably narrow range for A/F and spark?
Also, I know V/E table is critical but I will tune (and/or let the ECU tune) the base V/E tables to minimize O2 correction factors but need the right A/F targets to start with.
Attached are the current spark and A/F tables. The top of the tables were tuned by Barry during the dyno pulls so I think those are pretty close. Looking more at the cruise ranges and spark table transitions.
Definitely an EFI newbie so look forward to any guidance you guys can provide!
Thank guys!
