This Hondata dual ecu setup maintains the VSA and all other functions except cruise control as far as what I can tell from the Hondata website.

The cost of the harness alone is US$495.

If you have a compatable stock ECU you can use= US$1495

If you require a new ECU + Kpro + Harness = US$1995

Unless you're willing to send your standard ECU to the states for a week or two you're looking at $2400 for the ECU setup alone. Throw in another 500-600 for tuning and you might be able to get one installed and tuned for just under $3k.

Toda Au, can you confirm pricing for the Australian market?

Personally I'm going to continue with the Vi-Pec solution. Just waiting for the workshop to sort it all out (wiring diagrams etc.). Pricing should be very similar to the Hondata option if not a bit cheaper.
