Ashkellybarr Posted June 14, 2017 Share Posted June 14, 2017 Hey guys. so I'm going threw my Aw11 at the moment. running link ECU and because I'm running COP ign I'll use an output on the ECU to run the factory tacho. ive pulled a spare AW cluster apart and found the component to change. pages have confirmed it's the 30Kohm resistor in R4. where I'm getting stuck is what to change it too.. someone (see pic) has said to change it to a 12.5Kohm resister witch doesn't sound correct. following the link in OS search I've found this article now it states the coil voltage to be 200-400v however if I use the calc ( HV/30Kohm=X, LV/X=?) in 200v and then 400 it's a big difference, double in case you hadn't figured one being 900ohm and the other 1.8Kohm. so how do I actually find the EXSACT factory 4A voltage EMF on the coil neg?

Stu Posted June 16, 2017 Share Posted June 16, 2017 1kohm will be fine, you can adjust scale in the software anyway. 1 Quote Link to comment Share on other sites More sharing options...
