i have built a MS2 extra V3.0 board, hall sensor 5 v, wideband innovate system, running 3.2.1 code, tunerstudio v1.006, and have a couple of issues
i tried to set it up on the bench using a megastim, but was informed i needed the jimstim, which i have now got and built and tested,
testing the jimstim with a scope the RPM stays smooth right over the range as does the O2 output and rest of the outputs
now plug it into the ecu, all fires up and shows everything working, i increase the rpm and all is smooth until i hit 2555 rpm, then the rpm reading fluctuates wildly, showing a range of 2800 to 0 rpm, as i increase the rpm the rev counter reads zero and it stops fluctuating, meanwhile the ASE , Not ready, cranking and "not synced" all light up or flash like crazy.
the O2 readings are erratic as well, as i increase from 0v thru to 5 v (checked with meter) the readings goes from 12.2 to 16.8 and occasionally jumps around in the middle,
i have sat down with the msextra build manual and gone thru all the steps checking and rechecking what was installed and what should be left out and removed a couple of resistors that were not required but made no differnce so now currently stumped,
anyone got any bright ideas?
