I am replacing my current Haltech + Uprev Osiris setup with the newer Haltech unit that replaces the stock ecu. If anyone is interested in the Uprev Reflash, let me know.

RRR Dyno Tuning in Santa Ana has the car and is swapping the Haltech as well some tuning. Nelson is a haltech dealer and knows his **** when it comes to tuning. I'm holding off from doing the e85 just yet but I'll tune for flex fuel in the future.
I'm moving north east so I'm preparing for e85. Do you know if the red box can use the flex fuel sensor? And I'm going to PM you some questions I've asked in the past lol

New Haltech is on the car and will be tuned next week. There is a base map on the car right now just so it can start up and it starts up like a stock 350z even with the 1000cc injectors. Car would start up like **** before with the older haltech unit, throttle wasn't stable because stock ecu would fight the haltech.
That's odd you couldn't get a good start up with the pro harness haltech. I'm on 1000cc injectors with my full built engine, cams, heads and always had a stock-like startup on mine. Even switching over to e85 it still starts like a champ first key turn every time.
I actually had huge start issues with osiris. I was only on 800cc injectors with the osiris and once I switched to the haltech starting was easily tuned and has been perfect since.

Glad you got it all sorted out with the new system.
