Spark table switching on decel

Anything about Ford EEC tuning. TwEECer and Moates questions dominate, but there's some SCT and OBD-II knowledge too.

Spark table switching on decel

Post by EFI66 » Sat Jun 16, 2018 5:24 am

After disabling one of the HEGO's the car run very well on a J4J1 tune.

One thing is weird though.

When decel the spark tables switches from "2" to "9" and ends up in "8" untill I step on the throttle again
The spark drops from 34+ cruising to steady 15 when in table 8

Why does it do that?

I have set Altitude and sealevel spark tables to all 60's. I still have the Borderline and MBT table.
