the other two Link options i recommend are wire in.

LINK EXTREME & the new VOODOO NEO 4.

i run the Link Extreme. sale price $1826. free shipping, normally $2075.



i use Jeffrey Evans Evans Performance Academy for deep/shallow diving into the Extreme. Jeffrey has ONE HUNDRED AND THIRTY THREE high quality videos re the Link G5 architecture, each delving into one of the features. counterbalancing the vast array of capability is the fact that the Link makes it so easy to use. simple simple simple. once you have entered your data, fuel injector sizing etc, the ECU does it all. just like many jobs will be sidelined w AI, the tuning function has changed so you can easily not have a tuner on speed dial. i have run Link since 2013. one of my favorite features is the Virtual Fuel Tank. the ECU actually monitors your fuel use... here's my current digital dash.

Manufacturing Standard – ISO 13485

when i decided to run the Texas Mile in 2013 i decided to say goodby to my Power FC in hopes of gaining lots more features... such as active knock. i looked at Haltech but at the time there was some thought re errant spark breaking irons. maybe yes, maybe no, but no. Motech was the Pro Gold Standard but quite expensive and you had to add lots of other modems to get important features. Link and ViPEC offered all the Motech features but in one unit and friendly priced. ViPEC was primarily a rebadged Link. i ran and loved my ViPEC V88 until Jan 2020 when i updated it w the Link Extreme. i didn't have to change the wiring harness and it was quite similar w more features and speed.

if you have never wired in an ECU (i hadn't), ViPEC had a wonderful helper tool in the form of a ONE HUNDRED AND FIFTY PAGE manual. lots of pics, diagrams etc. not only did it make the job easy but it also greatly added to my understanding of how things worked. i have the PDF should you need it.

Link has all its arrows pointing upward... product, support etc. and now introduces the Voodoo NEO 4 G5. sale price $2283.60 shipped, normally $2595





all the good stuff from the two previous ECUs tuned up lots. while it is around $500 more than the Extreme, it has an onboard wideband system that i find valuable as well as being faster, and more capable. GPS, Direct Injection, WiFi, etc. sale priced at $2283.60

Inputs/Outputs

• Control up to 6 cylinders with port or direct injection and direct spark, or 4 cylinders with direct/port staged injection, thanks to:
  • 8 injector pins
  • 6 ignition pins
  • 12 aux. output pins
  • (4 Aux pins are shared with 4 DI Pins. You can only use each pin for either Injection or DI, not both at the same time.)
  • 6 ADIO pins

• ADIO are a unique pin type. ADIO can act as an Aux Output (switched or PWM), as an Analogue Input, or as a Digital Input, but cannot read PWM/frequency.
• Neo 4 has Aux/DI pins which are used as either an Aux pin, or a Digital Input pin. They can read PWM/frequency.
• Any unused injector/ignition pins can be used as an auxiliary pin

• GPS: Functional when GPS antenna connected (antenna included)

Data Logging

• 1gb logging capacity
• Logging over WiFi
• 100kHz max. total logging rate
• 250 logging channels

Size & Weight

• Length: 107mm (4.21 inches)
