need a bit of guidance  , had issues with the eis unit, (key jamming occasionally )
I removed  the unit  and read both r1 and r2 chips in eis with R270,, (4j74y mask) 
saved files epprom and flash bin , then purchased a used unit,  put both original files in the r1 and r2 chips  on the used eis ,
connected back to car and 
the key turns and car starts and drives, 
but when read with xentry or auto logic , there are control units not  able to connect too eis roof are 2 and showing errors in DAS and a gateway error, , the eis also shows no vin or mb part number in DAS, unable to read or single out eis in das, it just will not connect to them,

any  ideas ? thanks
