Hello, i'm Kuba from Poland, since i love my Benz and don't want any new, but hate ke-jetronic i decided to make conversion to MS... at the beginning i was using ms II v3.0, but next i installed p&h driver baord, than vr conditioners based on lm1815.... and at the end changed processor to ms III. my Ms lookes like this:


it is placed in renault 19 enclousure- waterproof with silicone.

on the engine i am using m104 3.2 fuel rail with ori injectors, coil on plug from audi q7 quttro, lpg injectors, magicIII vapours, k&n filter....


sory for the mess under the hood, but i don't have time to make it clear, since i'm spending almoust all my life working in hospital...

Going to the head.... since i changed to ms III i can't make my ve... i had problems with map jumping, but i think i managed to make it clear with some petrol filter on the vacuum lines...

My problem is strange... when i cross 75kpa on the Ve map my lc1 start to make some strange readings. I can't lower afr below ~13.2 sometimes 13.5.... it shows afr, than it is falling down very fast and lc1 shows 21.7 afr...on the idle, when i tried how low i can go with my afr i made it to ~12.5, than it is showing error. My friends told me i have problems with my egt, so i made my ignition map higher as this below:


but i don't think it is any better with my afr... for egzample, on warmup it should be around 12.5, but in my case when it is below 13 i have error on lc1, and it is showing 21.7 almoust all the time when warmup is on.... i have my lc1 on my daily driver since two years and i can't remember if it was diffrent in the past, but i think, that it caught errors as easy as now around afr 12. My friend in 3.6 with lower ignition map have readings below 9.0....
I don't know what i going on, but i bought new sensor, which i can't place in exhaust, because i am 450km from home.
i almoust forgot to tell You, that one time after start of the engine and recalibration of the sensor my controller showed error number 8.... after the engine cooled down the sensor was working as before. i have it in original place on the exhaust, i have no more catalisator....

Could anyone help me with this strange behavour of my sensor, so i could finish my project?? what do You think about my ignition map??
greets from Poland
Kuba
P.S. I decided to make conversion because of Pumpish Videos on Youtube...
