A little help for a newbie

[selmerguy]

Hi 4g63 guys. I recently joined your club and just started toying with my 92 tsi awd. My logging experiance is mainly in megasquirt and a few other standalones. All this with a wideband. I understand afr and timing but this palm logger has me alittle confused.

I just got it working today and I did a few logs which seem inaccurate in some points. I am using mmcd to log with. I set it up to read psi not bar so here are two points and the numbers

rpm 5843
injp 17.66
knock 0
o2-r .89
tps 72.2
injd 85.9
tim 24
cool 199.9
airt 114.7
baro 13.95 psi
egrt -24.7

the other
rpm 718
injp 2.04
knock 0
o2-r 0.00
tps 3.5
injd .7
cool 196.2
airt 124.9
baro 13.25psi
egrt 3.7

I know for a fack I am running 16 psi at wot. Why are my baro(boost) readings so far off? Also is there a good conversion for the narrow band o2 voltage to AFR? Can I hook up a wideband to the mmcd and how? I have a innovate lc-1 with xd-1 just sitting here waiting to get used. Thanks
Sam

I did a few more logs today and it is the same. The baro still reads wrong. At idle it is at 13psi and wot it is sometimes there or goes to 14.35 but never right. I am used to tuning according to afr and boost so this is very strange to me. When I see poster logs nobody posts the baro. Is this because it is inaccurate?
