Setting the A/F ratio?

[alundra]

Ok, I have a S12 with 8 sparks plugs system and emission control AND a stock 02 sensor came with this car.

I have take the signal that come in ECU for my A/F gauge.

At idle 14.40, 14.50, 14.60 with or without headlights electronics etc...

I know the difference between narrow and wide band sensor but for me it's sufficent for ECU, the motor and the monitoring of it.

I'd like to go at 0.8 bar or 1 bar but i prefer go safe because i need to know how make a detonation "gauge", i'm really scary about detonation in a car.

For 10.00 ratio is too rich and rich is'nt good for pistons too, right?

I'd like to remap but I have mk1 ECU as I said.... If you have any info on a mk1 remap I'll take it

What gauge have you got Alundra?

So what lamda sensor does it run off?

If you are using a stock narrow band one it will only show 15.2-14.2:1

Event at full throttle, with boost?

No air or oil leak.

No Check ECU.

That's why i'd like something for running stoechiometric in full throttle+boost but solutions are hard to find.

Thanks 30psi

I'm confused.

That gauge you have won't show the boost ratio's because its not a wideband lamda unit.

Why you said "wan't show"?

It's the same that you can see in the shop: http://www.jdm-per4mance.com/product...roducts_id/134

You can see the description on it.

I'll take a video to see what i said.

NO, wideband isn't needed for this meter, Yes i have a stock lambda sensor on my car; I'll some pics

So you don't have lambda sensor on s12 from UK.
