Good job Shane. Gotta be careful with Amazon race parts for sure. Knock off coils might be ok for a normally aspirated Nissan Leaf, but not for 400 kPa heroes.

I really enjoyed that. Expensive is great, but I have a fondness for cheap. That entire test setup (minus pressure chamber) can be done by many for under $100. I'll have to build one for my guys. I designed the Dwell Spark LED retrofit for the Sun Distributor machine.

That is the final conclusion, but I think you can even deduct more information from the graph shown after 6:40. The amount of energy stored in the primary side of the coil is 1/2*L*I^2. If the induction of both coils is the same (which it seems as the slope at the start is very similar), the amount of energy it can store is equal to the square of the current. For the cheap coil the current flat lines much earlier and lower. The final current of the good coils is double, meaning 4x the energy! The graph also shows that running longer dwell on the cheap coils will not increase current and thus spark energy. One last thing of note: if you do not need the spark energy, running shorter dwell times will reduce the current and thus the heating of the coils and can be beneficial to the lifetime of the coils. Last comment: cool setup and educational video!

curious what a flow chart will look like for an ignition coil failsafe options. if ignition coil dwell times are outside of required settings, set boost psi to 0, disable WOT, max rpm to 3000. curious what a fail safe setting will be when ignition coil temperatures are too hot. Mr. T as always i appreciate your sharing experiences! I am waiting for a tuners text book, author: Tuned by Shane T. will surely be SEMA's best seller!

Hey Shane just a question. Does dwell decreases when rpm goes up? Or in the standalone ECU can be tune steady on any rpm? Or can be set higher dwell when on high rpm?

Can you show how much different voltage effects the output? So say you lose an alternator when you are at the track and it’s running 12.2 volts during the run instead of 13.8 or so. Thanks

More expensive is not always better some companies work on “perceived value”. If it’s more expensive you perceive it to be better even though they are just marking up the cheapest thing they can get there hands on.

Hey Shane. Is dwell time reduced the higher the rpm that is present. Like on my turbo vr6 theres a dwell table and Im tryn to understand it to set it up. U seem like u kno wat ur talkin about and ur equiptment set up and testing shows it. So if my coils safe dwell time is 3.2 ms, should I set it at 3.2ms at 500 rpm give or take, and then at 8000rpm set that to 2.5ms, and then trend that through the rpm? or keep at 3.2 ms through the whole rpm? band?
@TunedbyShaneT
@TunedbyShaneT 3 жыл бұрын
The dwell should be set to match the peak output of the coil based on the battery voltage. Because the charging time is a fixed value, it becomes a larger percentage of the “cycle time” as the engine speed goes up. In other words there is less resting time the higher you rev the engine. This could result in overheating the coil, which would be the only reason I can think of to reduce dwell with RPM.

Hey and also so if the coil isnt charging enough the spark would be smaller or weaker right? Like say my coils max charge time is 3.2ms and I reduce that time to 2.5ms and test the spark, it would have a smaller spark right?
@TunedbyShaneT
@TunedbyShaneT 3 жыл бұрын
If the peak output for a particular voltage is 3.2mS then yes anything less than 3.2mS will have reduced spark energy. You can think of the dwell time as a throttle for the spark output. The less you use under peak output, the less spark energy is available.

You've got lots of things wrong with your test setup. Your plug at atmospheric pressure, it's sparking at only about 3KV. You connected the scope to the secondary side which you never do, it loads the circuit and distorts the numbers by 50%, you're over dwelling the coil and you don't even know what saturation is?
