Features

The FuelTech FTSPARK is an extremely high energy Capacitive Discharge Ignition (CDI) system designed to meet the highest spark requirements for racing. Developed for high horsepower combinations and tested proven on 5,000+ horsepower engines!

It is compatible with any ECU on the market! It's able to generate a spark with up to 600mJ (mJ=mili Joules) of energy and is capable of firing the spark with 125 Amps of current in the coil primary. With these features, FTSPARK generates a spark with approximately 5 times more energy and 10 times more current compared to a SparkPRO ensuring a burn in any condition, especially in extremely rich air fuel ratios.

 

Technical Description

  • Compatible with piston and rotary engines
  • Programmable power between 400mJ and 600mJ through CAN or analog input for energy level adjustment
  • Coil primary current up to 250amps (depends on coil)
  • CAN communication with FuelTech Power FT ECU line for equipment diagnostics and datalogger channel recording
  • Anodized aluminum housing
  • Automotive connector with gold-plated terminals
  • Serial bus (1 wire) allows to use only one output from the ECU to trigger all FTSPARK ignition outputs
    This only works with FuelTech ECUs - FT450 and above.
  • 430v to coil primary voltage, which helps prevent system interference
  • Size: 4.92 x 6.0 x 1.9 in., Weight: 32.8 oz
  • Maximum operating time with minimum power 400mJ: limited by the maximum operating temperature
  • Maximum operating time with maximum power 600mJ: 20 seconds
  • Voltage supply required for full power: 14-19V. Minimum engine start voltage 8V
  • Maximum operating frequency: 670 Hz
  • Maximum Current Consumption:
    FTSPARK-1 (1 coil):
    20A / 30A / 40A to 4,6,8 cylinders @ 10000rpm
    FTSPARK-4 (4 coils): 20A @ 10000RPM
    FTSPARK-6 (6 coils): 30A @ 10000RPM
    FTSPARK-8 (8 coils): 40A @ 10000RPM

MAPxRPM table to adjust energy level of the FTSPARK with a FuelTech Power FT ECU:

Datalogger channels:

Discharge time:

  • Each output has an individual monitoring channel for the discharging time on the coil, which allows to diagnose malfunctions on the coils, channels or harness. The discharge time of the capacitor is not related to spark time, a long discharge might indicate problems on the coil or harness and connector.

Supply voltage: 

  • Shows the effective power received by the FTSPARK.

Supply voltage drop:

  • Shows the difference of the voltage supply between the FTSPARK and the ECU. In case this value is too high, there might be a problem on the power harness of the FTSPARK.

Capacitor voltage 1 and 2:

  • FTSPARK has two capacitors banks that are charged and discharged alternately on the outputs, allowing for high engine rotations and operation on ROTARY engines, the first bank of capacitors fires the outputs A-C-E-G and the second bank fires the outputs B-D-F-H.

Capacitor charge time 1 and 2:

  • The monitoring of the charging time allows the diagnostic of a possible internal problem on the FTSPARK, power deficiency or RPM limit settings where the required charging time cannot be respected.

Look great on my preteen with just a little chub who wears 32 or 34" with 32" inseam
Size: 32, Color: Navy, Size: 32, Color: Navy
I got these in a 32" waist for my preteen son who is between 32 and 34 right now. He either has pants that are too tight or too loose and he feels like they're falling off all the time. These fit him perfectly. The length hits just right, the stretch in the waist is enough that they fit well without squeezing his pre-growth-spurt chub out in an unflattering way. They are comfortable enough he came out with a smile and asked if he could keep them on. That hasn't happened in a very long time. He loves the pockets. I'm really hoping that when he grows a few more inches they still look as good on him. He did say they conduct the temperature a lot, so if you're wearing them outside on a cool day, you might need to layer a bit. They also do have a bit of a swish too them as they are the water repellant material, but it's a quiet swish rather than the 80s/90s rain wear swish too many of us remember too well. If you have a little chub and want to look sleek, these are a great option. I'm impressed with how flattering they are on his current build. He wears pants with a 32" inseam and these fit him just like it's shown in the ads, snug right around the ankle by the shoe. I haven't included pictures of him wearing them as there are already quite a few of those, but these do attract dog hair more than an average pair of jeans in the crotch and ankles. Why those spots, I have no idea. I just know that our cream colored Siberian husky is shedding a ridiculous amount right now and you can really see it on these pants, so be prepared to get some sort of lint roller/remover for these. As a side note, it also had the appearance of pilling in some of the pictures I took, but I couldn't see or feel anything there, so I'll be watching to see if there is randomly the same dust all over the pants or if pilling starts to happen. Also, he knows chub or no chub he's amazing and handsome and I'm proud he's mine, so it's not me being a harsh mama, just an honest mama in this review.

Not as comfortable as expected
Size: 34, Color: Navy
This is a review of the TACVASEN Men's Casual Cargo Joggers Hiking Pants Water-Repellent Elastic Waist Drawstring Tapered Work Pant with Pockets Pros: The fit is as expected. The quality seems to be durable Cons: The water-repellant elastic makes these pants feel like I'm wearing the pants from a rainsuit. They do not breath well and I get warm in them quickly. The cargo pockets are much larger than they look in the pictures, and almost feel like an afterthought. The pant legs tend to ride up several inches when I sit down.

Comfortable and functional joggers with good pocket space and durability
Size: 32, Color: Navy
I ordered the TACVASEN cargo joggers to use for both casual wear and light outdoor activities, and they have been a solid all around option. They strike a good balance between comfort and functionality, which makes them easy to wear in different situations. The fit is true to size with a tapered leg that gives them a modern look without feeling too tight. The elastic waistband with drawstring makes it easy to adjust, and they stay in place well throughout the day. The material has a slight stretch, which adds to the overall comfort when moving around. The pockets are one of the standout features. There is plenty of storage space, and the cargo pockets are actually usable without feeling bulky. They are great for carrying everyday items when you are out walking or working. The fabric feels durable and holds up well with regular use. The water repellent feature works for light moisture like drizzle or splashes, though it is not meant for heavy rain. They also do not feel too heavy, so they can be worn in mild to slightly cooler weather comfortably. In terms of style, they have a clean and versatile look that works for casual outfits or outdoor use. Value is strong for the price, especially considering the comfort, storage, and durability. Overall, these joggers are a practical and comfortable choice with good fit, useful pockets, and reliable quality for everyday wear or light activity.

The middle ground between pants and sweats
Size: 32, Color: Dark Grey
Love these casual pants and the fact they go well with practically everything for a quick trip outside the house. The fit is comfortable and soft. They stretch well and have plenty of pockets. I’ve already washed these a few times and seem to be holding up well.
