On flashed OEM computers the current draw on the internal MOSFETs is often monitored for coil failures. This calibration will also need to alter as the current draw on the MOSFETs are significantly less load and may trigger a false misfire error due to the current load being focused on the R35 smart coil instead, \u003cmeta charset=\"utf-8\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eConverter bypass box must be used with the factory DME or it will burn out the smart coils.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBillet Alloy bracket - engineered to fit ignition coils in a manner that allows easy access to all the coil plugs in a non-invasive way.\u003c\/li\u003e\n\u003cli\u003eCustom injection molded silicone stalks (6) - designed to reach and seat the spark plug on the correct angle.\u003c\/li\u003e\n\u003cli\u003eWiring Harness - choice of 2 wiring options offered:\n\u003cul\u003e\n\u003cli\u003eOEM ‘Plug \u0026amp; Play’ wiring which utilizes your factory ignition wiring aimed at use with flashed factory DME computers.

These coils require an IGBT signal to be sent from the factory DME (Engine Control Computer) to fire them.\u003c\/p\u003e\n\u003cp\u003eThe DME internal circuitry uses MOSFET transistors to make this IGBT signal occur. Specifically, on the MSD80 model DME, it uses part number IRFW644B MOSFET (\u003ca href=\"https:\/\/datasheetspdf.com\/pdf\/753457\/FairchildSemiconductor\/IRFW644B\/1\"\u003eDatasheet\u003c\/a\u003e), on the MSD81 model it uses ISL9V5036 (\u003ca href=\"https:\/\/www.alldatasheet.com\/view.jsp?Searchword=ISL9V5036\u0026amp;sField=2\"\u003eDatasheet\u003c\/a\u003e). Unfortunately, these parts often fail in just a few short years with 30BA \u0026amp; 30BB DME internal failure Optional Colours to choose from are Grey or Cardo Zinc their task when ignition components become tired and worn-out. They heat up and eventually fail which leads to some pretty expensive repair\/replacement costs. Further information and a more in-depth technical analysis of these issues can be found here: https:\/\/bimmerprofs.com\/ignition-coils-episode-2\u003cspan\u003e, the team at BimmerProfs delves into the DME ignition method showing unfortunate \u003c\/span\u003eparasitic resonance voltage oscillations and why they occur.\u003c\/p\u003e\n\u003cp\u003eTo avoid these faults, we moved away from loading up the DME to fire ‘dumb coils’ and stuck to ‘smart coils’ like our other kits that are proven to perform well in high 1000HP+ applications. With our kit, the signal from the factory DME is converted to a low voltage trigger putting far less load on the factory trigger circuitry prolonging their lifespan.  The signal conversion process takes 1μs (1 millionth of a second) to ensure no timing is affected, all that is needed is to adjust the DME dwell settings to correspond with the upgraded coils and you’re ready for more power!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eWhy choose this ignition upgrade kit over the others out there?\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThere are many options out there, we suggest always do your research and also check out the examples of ignition coils used on other platforms rather than sales pitches.  Unfortunately, the DME has an internal componentry that is prone to failure due to excess heat. So, loading the higher dwell times from other “dumb” coil upgrade kits that promise higher spark performance is not an ideal decision.  Our kit ensures less load on the DME’s MOSFETs while still offering a proven better spark performance.  The proof is in the pudding and we are very proud to have World Time Attack track winners and Drag record holders use our kits on their cars!\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0354\/8135\/4376\/files\/N54-QUICK-REFERENCE-INSTRUCTIONS-A.pdf?v=1622159793\" title=\"Quick Reference
