well I decided to finish installing mods I have, last night, I installed my SAFC II dual intake dual maf, dual widebands and I attempted the Zem.. what does this mean? Received Version response with bad checksum I keep getting this error message when I try to connect to the Zem I have replaced the Batt inside, the cr2025. and I still get it.. it seems all chips are seated tight in the zem unit.. I am getting some funny AFR #'s also when I am running on my chip.12.6 idle and jumps up off the chart if I blip the throttle on both banks.. I don't know if the wide bands need calibration or if my safc is set up wrong, I am running it on a single pop chip and have it 2 in 2 out, add..where should the afr's be?.. All this tunning is new to me.. I like nuts and bolts, LOL..
