AEM smart coils/LSx coils on Apexi Power FC

Using the AEM smart coils as a replacement for your stock OEM coils is a GREAT option for many Power FC users. Nissan SR20DET and RB20, RB25, RB26 can all easily be swapped to the AEM smart coils for a MUCH hotter spark resulting in crisp throttle response, a better over all burn and higher power without ever blowing out spark even at 30+ PSI of boost. For those of you on an extra tight budget you can also use LS1, LS2 and LS7 coils which can be found on ebay or in the scrap yards for roughly 80% the cost of new AEM smart coils. Keep in mind used coils are not always the best option and spending a bit more on new coils can save a time and $$$ in the long run.

Tuning Ignition Dwell Power FC LSx/AEM coils

Brewed Motorsports uses the Datalogit tuning software and cable for all Power FC tunes. Setting up the Coil Dwell for aftermarket ignition coils can be a bit tricky as the PFC/Datalogit displays Dwell in Crank angle (not miliseconds) as most EMS do. If you have any questions or concerns about what settings you need for your Power FC contact us anytime at 1-888-290-3213

**For those that would like to do their own math here is the formula you can use to convert ms. to crank angle. Simply plug in your coil Dwell time and solve for X.

T=X / (.006)rpm Or [(.006)rpm]T=X

T = Coil dwell Time in Milliseconds
X = Crank angle

    Hi, I was hoping you could help me. I’m thinking about getting the p2m coils. I have an S14SR20DET power fc D-Jetro. Do I have to adjust the dwell time for installation? Also, does your Tuner ever make it out to Oregon?
