V2 Q about stoch setting

[restless@westnet.com.au]

on F8 what happens if you change the stoch setting on the v2 can you get it display /log a higher or lower value ??

[joecar]

You set it to the default value that your wideband uses.

hi mate
could you pleas elaborate on that for me
what value should i be putting in ?
tech edge 2j9

what im trying to do is get the wideband to read 1.4 AFR richer to match the dyno readout dyno 10.1 TE wide band 11.5 ,I have re calibrated the TE in free air and also tried a new sensor
thanks

For example:

say your wideband assumes stoich is 14.7 (i.e. for E00 petrol/gasoline)...

then say you run a tank full of E10 (stoich is now 14.2), at stoich your wideband will still read 14.7;

but if you set the default to 14.2 (either in the wideband or in V2), then V2's wideband AFR pid will now read 14.2 at stoich.

[joecar]

Also note, you should be using Lambda to tune with (so you won't be dealing with differences in stoich)...

lambda = 1.00 --> stoich/CL.
lambda = 0.86 --> NA load.
lambda = 0.78 --> Boost load.

what value would i have to put in do that
thanks

[joecar]

14.7 * 10.1/11.5 = 12.9


Try setting it to 12.9.

thanks mate
appreciate the help
cheers

14.7 * 10.1/11.5 = 12.9


Try setting it to 12.9.

it does drop it but it looks like about 2.2 ish AFR but i will have to do a WOT log to to compare it to my other WOT log on full boost
cheers

[joecar]

Try (12.9+14.7)/2 = 13.8
