I didn't know Hydra 2.7 was out. We have the same injectors. I'm on Hydra 2.6 and yes cold start in cold weather has kind of sucked. I wonder what other benefits there are though-- I'm kinda getting tired of having to pay and ship for lameass hardware upgrades.
How much did it cost for the IM welding?
Yeah the coils are probably overkill but I just couldn't help myself.
I am waiting for the 2.7 upgrade to come back from them right now. 2.5 units had to have entire new board installed, I believe the 2.6 is just a firmware update. anyway there are a bunch of new tables and I am not a talented tuner but I will try and work with Tim Bailey to learn something when he tunes my car.
here is the list of features that hydra emailed me
The Hydra2.7 has complete new firmware and software along with new processor with onboard datalogging and new idle, boost control, aux map and long term trim strategies. The 2.7 will also have capability to configure for additional sensors as inputs with configurability. Stage5 Epsilon has built in CAN Bus for use with external dashes, so you can run a dash and tune at same time. Hydra2.7 will be firmware upgradeable remotely without sending the ecu back. Each stage will be upgradeable to the next remotely without sending the ecu back.
You can also just buy individual Capabilities if you do not want the next full stage upgrade.
Stage 1 Alpha and Stage 2 Beta will be stripped down versions with less outputs and inputs then the current Hydra2.5 and 2.6. To get equivalent Outputs as the Hydra2.5, you will at least need the Stage 3 Gamma upgrade
