Ignition upgrade kit - Stronger & faster spark control- A.S. Motorsport

[A.S. Motorsport]

Hello Everyone,

High performance ignition coil upgrade kit, fully compatible with OEM ECU and parts.
Full direct replacement & 100% reversible & fit's underneath the coil trim panels!

This system features numerous improvements over the dated 27 year old ignition the NSX uses.
The kit is designed to fully replace the ignition yet plug in to the standard loom, and provide more accurate, stronger spark whilst being forced induction compatible at 200 HP per cylinder.

Improvements versus OEM

• Much lighter modern electronics, 1/3 weight of the OE coils.
• Stronger more exact spark with improved control

Response charge time of just 2 milliseconds​

Capable of handling 200 hp per cylinder​

• Better thermal properties reduce heat soak and corresponding voltage drop.
• Eliminates fully the ignition control module assembly on top of the throttle body. (less failure prone parts, less weight)

Plugs in to OE plug for the ICM and the engine loom for the coil feed.​

• Features integrated module to have the coils work correctly with the output of the Honda OBD1 ECU .

Module compensates for feed signal difference, earthing and resistances. (these coils are designed for use in Can-bus controlled Lamborghini's and Race cars)​

Compatibility

• 1990-1999 EDM OBD-1 NSX
• 1990-1994 USDM OBD-1 NSX
• 1990-1997 JDM OBD-1 NSX

Coming soon:

• 2000-2005 EDM OBD-1 NSX
• 1995-2005 USDM OBD-2 NSX
• 1998-2005 JDM OBD-2 NSX

Aftermarket ECU

• ALL STAND ALONE ECU's

Benefits / Usage
So a lot of you are going to think, cool but what is the advantage i'm getting out of this?
Let's split it up in four scenarios,

Stock to Mildly modified NSX running OE ecu

• Lighter more reliable ignition
• Alternative to discontinued OEM ignition coils which are known weak spots in the NSX
• More exact tune-ability in combination with for example a RDX upgrade & more exact spark control 6000-8000 RPM
• Not susceptible to water/moisture damage on the rear bank

CTSC NSX (piggy back FIC)

• Better suited to forced induction
• Handel's the added heat soak better of the supercharger
• Boost ignition timing is more exact, stronger spark and a more exact point in the timing table
• Eliminates the stock ICM which can be hard to reach on CTSC cars

Turbocharger NSX (stand alone ecu)

• Stronger spark able to properly deal with high boost application
• Capable of handling more timing resolution (coil charges faster and more exact thus more time to spark for any given cycle)
• Eliminates the stock ICM reducing complexity of the electronic system

Naturally aspirated NSX (stand alone ecu)

• Improved response and charge times allow more exact spark timing control and duration (thus more exact tuning 6000-9000 RPM
• Improved spark voltage and strength (also during heat load) allow for better combustion control allowing for more aggressive setups.
• Simplified packaging for ITB cars

Kit contents
Fully plug and play, full serviceable and reversible

Fine, I'll play.....payment sent.

 

[BUGS2K]

When will this be available?

 

[Track Addict]

Great product, awesome vendor! I can't say how thankful I am to all the vendors within the NSX community that put so much into keeping our cars going.

Love the idea, especially now that the rear bank OBDI coils are discontinued. You will be hearing from me when I need to replace a coil.

 

[furinax]

Wow, great news! Would an AEM ECU need special tuning to get these to work or would it be plug & play?

Hi Adnan,

just a quick question:

How are these new coils secure to the valve cover?

the old coils have 2 bolts each to tight them down, but these seem to be just pressed in.
my concearn is if they can slowly come out with normal engine vibrations.

Thanks,
Nuno

When will this be available?

They are available for order right now, we have at present still one set left the others quickly sold,
New batch of wiring looms and customized coils should be coming in a week or so

100% fully plug and play, you can adjust the coil charger values to match the improved response timing.

On nearly all modern cars coils just press in, yet as extra piece of mind we include rubber bushings which you can stick on the coil covers.
The rubber boots are machined to very tightly fit in the NSX coil sockets,

FYI, when Lamborghini uses these coils in a Hurricane they plug in, Ferrari & BMW M use exactly the same setup.
I've never had one of the coils come out even at 9.000 rpm in any of those

Hi Adnan,

you more than answered my question...

Thanks,

Can I buy just the wiring loom?

Can I buy just the wiring loom?

Coilpack's are modified for the NSX too, so just a loom won't get you there.

 

[nis350]

How about the reliability of the system? It would be tough to get spare parts if any of the components goes bad being in United States.

Do you know how much weight is saved over the whole exchange?

The coils we use are used in OE in Lamborghini and a number of other sports cars (Ferrari/Maserati, Audi RS6, etc)
So these have been thoroughly tested in a OE setting on the NSX we've ran this on high boost cars and NA cars for quite some time.

And in the future if a coil would need to be replaced we can fly in the coils in 3 days and at a fraction of the cost of a OE NSX coil.

Quite a lot, I'll put the system on a scale vs the OE later this week.

Just lose some weight fatso

 

[scammy]

just lose some weight fatso 

lol

 

[foundry3]

What is modified in the coil?

 

[8R6]

are 1995 USDM compatible versions available yet?

 

[NSX1145]

Ready for 2000 3.2L ?

 

[jagtiger]

Anyone installed this yet? Any feedback with the install and performance woud be highly appreciated. ��

 

[A.S. Motorsport]

We're working on a OBD-II compatible version with a modified circuit in the center module to satisfy OBD-II communications.

FYI,
This a complete plug & play kit, full reversible and offers excellent water sealing vs the older bolt in coils, the seals also are machined to fit specifically in the NSX valve covers.
No need to buy any separate parts to complete installation.

 

[angus]

Also waiting for OBDII version.

 

[bonhamsurf]

Will these help performance with my car? I have a single turbo with flex fuel. During tuning on E85 we could barely make 800whp due the OEM coils. My tuner said if I could find coils that could handle stronger power, we'd make another 100whp or so. Will these coils fix the issue with OEM coils ha where eliminating power.
