Either this or the Sparktech requires a 15A, I blew my 10A on the first startup of last season, forgot there was fuse...cost me a few hours of frustration.

 

Bump for good info
Car died last out of the blue
Runs tonite!
Been running the spooling up kit for abt a week

 

I've recently installed the Spoolin-up kit and I've blown two 10A fuses in a short period of time. I also have an AEM EMS so this may speedup the process of the short life span I'm getting from the 10A fuses. Glad I found this thread as I was starting to think I had a problem with this particular circuit. I'll be installing a 15A fuse and see how that goes.

 

Matt shipped me a 15a fuse with two kits I received last week.

 

Could someone take a photo of the fuse box & have a arrow or show an indication on which one it is? Changing from 10A to 15A for spoolinup cop kit.

 

Current draw is directly proportional to dwell time up to max dwell so you need to know the specific dwell time for your coils so you do not run too high of dwell and exceed the current capabilities of your fuse.

If you run the typical Denso coil with the Spoolin COP...Toyota 90919-02240 (Denso 673-1306)
then you need to run the following dwell values...

8V 6.3 ms
9V 5.3 ms
10V 4.4 ms
11V 3.8 ms
12V 3.2 ms
13V 2.7 ms
14V 2.4 ms
15V 2.2 ms

If you run the max dwell of 3ms@14v it will draw 11amps and blow your fuse. For the AEM users you should be able to directly program dwell.

 

Bump someone?

 

Just wanted to bump this. I blew the number 1 fuse under the dash just a second ago.
I'm using Honda Denso coils, custom setup.
Mine happened on start up too. I have an AEM v1 (which I hate with a passion) it hit once or twice and I thought it was going to start but had to crank it again and it never hit again. I cranked on it for a good 5 min before I hooked up the laptop, saw it was stat syncing and checked under the hood. Nothing felt hot/looked burned etc. Thought to check the engine fuses, sure enough first one with an engine sign on it was burned out the top. Replaced it temporarily with a 20 amp and it fired right up.

 

So I blew the #1 fuse everyones talking about and put a new 10a in and its driving again, but i looked through the wiring diagrams and as far as i can tell, this fuse is only used to activate the ignition coil relay, which powers the coils from a 20a fuse. so unless i am confused, there shouldnt ever be any electrical load on it?

the #1 fuse is the one i circled in yellow. it clearly only goes to the engagement coil of a relay. I traced through the wiring diagrams for an evo8 and evo9 and cannot find anything else on this circuit.

the fuse circled in orange is the one that the (factory) coils actually get power from, according to the diagrams. I have a COP setup of unknown origin from a previous owner, so i didnt do the install, but i just cant see how a heavier ignition load can affect the fuse that activates the relay that powers the coils.

anyone have any ideas?

According to my manual the LHD version is without relay and Nr 1 fuse goes to the coils.
But on a RHD is is the way that you have posted.

 

wow, thanks
where did you get the LHD manual?

Question: I'm on the fence to getting a COP DIY kit, is it worth it or stay stock & use money for something else?

Thanks
