Platnum sport 1000 does. Factory ecu controls vvti on mine (Sprint 500), use to have Camcon assist... but removed it along with turbo timer. Im the type of person who likes to minimise the number of electronic devices in my car. VVTI honestly isnt worth the time spent tuning IMO. You would be looking at a couple more hours of tune time, for a few whp under the boost curve (max power won't change).

Yeah the Haltech Platinum sport 1000 is currently my ecu and is great in efficiency tuning so far. I cannot understand how the factory ecu is controlling the vvti when it needs certain controls that now are connected to your Sprint 500 ?

I have to disagree with Blown_xa about VVti. I got about 20 torque and 25 bhp till 5000rpm with as far as 30Degrees Advance till 5psi boost. VVTi was tuned within an hour so it was surely worth the time spent tuning !

The Haltech ecu can handle idle control (make it a point that not all standalone ecus handle it so check out the specs first). Attached is my idle control page on ecu.

The factory ecu still sees everything and controls the vvti actuator just like factory, this is because of the way mine is wired. The halted sprint 500 doesn't control vvti, so that is how it should be wired. However, with the sport 1000 in your case.... It is wired up and can control vvti. It is no surprise you got gains, but that is because you started at a static vvti state ( you started with zero advance).

And I thought the Sprint series were better than the Sport Series!

The sports series has more features... aux inputs, outputs. Also has cold start, sprint does not. We use the sport 1000 on scion tc's, haltec actually created the basemap for that car with us on our dyno years ago. So the vvti for that engine management was already set up ( tuned bone stock car).

I like the Sprint 500 though, it is physically tiny, and does everything I need.
