Dwell vs RPM Ignition Coil

[@macgyverdroid]

Newby here Em i rigth? For example on distributor application The more the RPM goes up the dwell deccreases And when the rpm Decreases Dwell gets high

[@ADPTraining]

Maybe but not always.

@@ADPTraining so you're saying you dont have a deep understanding of automotive ignition

[@treadmillrepair754]

This tester is a PWM generador, one key modifies the frecuency and the other modifies Duty Cycle. Is ver y easy to do with a LM555. Cheers

Ricardo B which mosfet would you use for a driver ?

[@treadmillrepair754]

New Level Auto is posible to use IRFZ44.

[@ADPTraining]

+Ricardo B no, I use a dedicated PWM Micro for this tool. The 555 is from the 1970s, and doesn't do PWM over a wide range.

[@ADPTraining]

Ricardo B there are a few dozens IRF series mosfets that you can use. Just mind the static charge.

[@treadmillrepair754]

Yes is posible to use an Arduino.
