[casper002]

Hi people...
i just want a little help with a few settings in the below info,
I think once i can get thigs sorted here it might make it a bit better for me.
I do think i am getting there but by hell i didnt think it would be this hard


what is best to put in the boxes in there
like

change ego limit above(kpa) ?????
change ego limit to (+-) ?????

i think for ve table 1 should be ON

ve table 3 off
speed dencity
and use targets = always


Now then can you help me in here too...

in the exhaust gass settings too

like whats best to do in here

like

EGO sensor type = wideband i am using the lc-1
EGO switch point (v) ???? i think its got to be 2.5
ignition events per step ????
controller step size (%) ????
controller authority +-(%) ???
active above temp ???
active above rpm ???

can anyone give me some advice on this or the default settings for a wideband setup

thanx again

Thats my settings and they work pretty good. Make sure you setup for the innovate 0-5v 10-20afr in your mt config and program your lc-1 with lm programmer.

There is really no "best" value. Otherwise they would be programed in and not adjustable.
Some of the settings, like ignition events per step depend a bit on what RPM you are running and how long your exhaust is before the EGO probe.

I don't remember MSI well enough to give consise settings for you.
But I would start with the defaults and read up about Wideband in the MegaSquirt tuneing instructions. Then if you find issues you can tweek settings.

For LC1 using 10-20 afr gives AFR of 14.7 at 2.35 volts.
That would be your crossover point... unless you are using AFR target table then it is irelivent (If I am remembering msns-extra wrong, please correct me)

I calculate the target voltage like this:

.5 volts * ( AFR - 10) = Target voltage
