Installed Spoolin up COP and noticed instant smoother and quieter idle.
Car pulls so much smoother.
I put the smoothing at 10 on the 1st one.If I put smoothing at 1 the spoolinup log still is smooth but the stock coil log isn't as you can see in the 2nd graph.
Gains are 10-15 hp throughout.
I purchase the used coil kit.

 

I bought the same kit and found the exact same results. It's a must do mod,

 

Looking good!

Those are freakishly high gains though, was one pull in colder weather? Maybe your stock coils were about to give up on life! Either way, awesomeness.

 

Pulls were around the same temp,same stretch of road.I replaced one coil pack which was bad a couple months ago.
Just an amazing product!!!

 

I agree with matt on that gain maybe 10 whp at the most ..From looking at the boost log it looks like it's spiking more boost in the red one.

 

I changed the graph to one with higher boost before COP.

The results then.

 

Looks like the red plot is making more HP and TQ with less boost than the blue plot. Hard to attribute those gains to just a COP, did timing change between the runs? ie, air temp or baro differences? Did you log timing for each run?

 

Quite interesting. I'm still deciding which COP to buy. I like the Sparktech non-cdi but with the CDI being better I'm torn on spending $500 now only to want the CDI later.

Part of this mod for me is just to get better fuel economy before I get the other mods that require better spark (at which point fuel economy is out the window).

Basically I'm toying with a friend who has a hybrid and gets 31mpg in the winter. I think that's beatable in my car without the lack of performance his car has. Just something to do until the cash comes to get serious with the car.

What I'm curious about is how much better a stronger CDI spark would be compared to the non-CDI units. Or is the difference really more of a blowout issue and just a non-CDI would give me the same economy increase? My IX only has 38K miles so over the life of the car I'm considering the ignition upgrade basically free since the mileage gains will more than pay for itself.

 

Yes,Timing on the COP run was 0 at peak boost up to 14 by redline,There were 2 spots with 1 count of knock at 4700 and 6300.
The before run was the same timing with 1 count of knock at 6000.

 

With a better ignition the timing would advance more to take advantage of the better spark.

 

I only lowered the boost slightly due to adding the new mod.I wanted to make sure there were no issues first.
No timing changes were made.

 

What other mods do you have? That's an impressive gain!

 

Only mod change was the COP and new spark plugs.Old plugs only had about 1000 miles on them.I just wanted to start fresh.

 

Nice gains! Guess I need to move this higher up on my future mod list
