SM question

[Shimy87]

Doing some tuning today working on launch mostly. Letting off top of 2nd. The SM records O2 but shows no mph. It does show mph if you scroll to it so it is reading it. Still reading over 800 for O2's down low and chip is turned down to 113 setting in 1st, 125 setting over all is showing 792 O2s top of 3rd

Ran out of time to continue today

Also set first gear timing to131 setting

Hold the recall button to show timing retard and o2 millivolts. While pushing the recall button, press the button on the left side at the same time and SC will display the mph of the lowest o2 recorded.

Yes I know, it shows the O2 but shows 000 on the mph ?

VSS is bad??

[Shimy87]

But it does show mph when you scroll to it on the sm

Full throttle run?

[Shimy87]

yes, but not thru 3rd, let off in middle of 3rd. The weird thing is it would record the O'2's but not give me a MPH. I thought maybe VSS also so I checked the SM mph setting and it is working fine.

I believe the tps has to read above 3.0 volts for more than one second..that is why I asked
