I there any one hos knows wich kable from the ecm is to tach output so i can use it för a shiftminder and a logger
 
Try probing the wires at the coils, Tach shoud read in A/C voltage. Just a guess but if you have good multi meter it shouldn't hurt anything to check. (I use this technique to find it on remote start alarms for cars.)
