Lambda sensor to L8 MSD closed loop.
Zirgoniums give 0-0.9v Sierra Cossie 4wd titanium 0-1v if i understand right.
Can it work right to send Innovate wideband lc-1 simulated narrowband output signal to L8 box with msd closed loop chip.
What MSD closed loop chip wants in input? Somebody says that only titanium lambdas work ,but i have NTK oem sensor right now and closed loop works ,but.
in idle when engine is warm exhaust popping little and engine shake little same time. It feels like running little bit lean.
Afr fluctuate 14-15 in idle ,most of time close to AFR 14.5
I tried Base co% adjust to enrich it a little ,but it not help at all. If i understand right ,lambda sensor is connected when co% adjust are made ,or do i have to unplug it?
Can lambda sensor affect to this. I use OEM sensor ,not original titanium.

I can't see there would be a problem using the LC1 narrow band output.
Try adjusting to co pot to give a better idle ive found cossies like to run in the 13's afr
in an ideal world 14.7 at idle would be great but it never happens like that.

Normaly the problem is the ignition system.When running afr around 14.7 at idle you need open plug gap but then you get problems at high boost.You need better ignition system.Wasted spark or after market ignitionampfilter and better coil will cure the broblem.

Better ignition maybe cure the problem ,now i have original distributor system with Crane cams fireball LX91 coil and all wires and all are good condition.
Spark gap 0.7mm without high boost problems 1.5bar. I try 0.9mm gap if it not too much in boost.
Chip fueling in idle can be little lean to this engine maybe.

Dear friends, do some body know what MSD closed loop chip wants in lambda input?
I using also XD-16 as original lambda and closed loop works normally with default settings, but I hope it is possible to improve it.
Default settings:
1.099 Volt at lambda 0.958
0.45 Volt at lambda 1
0.103 Volt at lambda 1.022
How to improve idling and closed loop by changing this settings?
