Adamw Posted October 7, 2021 Report Share Posted October 7, 2021 Anything but the VAG coils. The VAG coils require 15mA drive for the signal. Most others are ~2mA. GM LS, IGN1A, K20, Toyota, R35 would all be able to use a 5V pull-up. Quote Link to comment Share on other sites More sharing options...
Mohamed ayed Posted October 25, 2021 Report Share Posted October 25, 2021 @Adamw tried 240 ohm pulled up to 12 v and no hope the resistance between pins 2&3 in the coils im using is 386 ohm any suggestions ? Quote Link to comment Share on other sites More sharing options...

Adamw Posted October 25, 2021 Report Share Posted October 25, 2021 This is why I said right at the beginning that these coils arent recommended. You will need to connect an oscilloscope to the trigger pin at the coil to see what voltage is there. These coils need very close to 5.0V to start charging and very close to 0V to spark.

Shamanyak Posted November 25, 2021 Report Share Posted November 25, 2021 Can an R8 coil be connected to a bmw m42 stock engine? Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 25, 2021 Report Share Posted November 25, 2021 This forum in for Link ECU's. We cant help you with a factory ecu. You would be best to ask on a BMW forum. Quote Link to comment Share on other sites More sharing options...
