Hello all,
So I finally finished installing everything. I am very please with the numbers but now I am having hot-start issues. I am currently running the UTEC and the car is running great minus the hot start issue.

Is there a work around for this? I was thinking about reflashing the stock ECU to work in tandem with the UTEC. Has anybody gone this route... if so how is it working out?

MOD LIST...
Vortech Supercharger
TurboXS UTEC
660cc Deatschwerks Injectors
Walboro 255lph Fuel pump
1 step colder NGK plugs
3.12 pulley
GTM Pulley mod
DC Headers
Crawford plenum
Nismo thermostat
Hi-flow cats
y-pipe
Invidia TI exhaust

 

Had reflash ECU via cipher and Utec. Had hot start issue at first, but figured had dirty TB cause this issue ( well it was my case )

 

is that 395 hp on a conservative tune. cause i had mine at 400 on the stock 3.33 pulley

 

~30hp can be the diff between a hub dyno and one with rollers.


Subscribed to this thread, two local guys just did the 2.87 pulley and 600cc also experiencing the hot start issues.

 

I know someone with vortech, 600cc and osiris (no utec) with hot start issues. Takes maybe 5-10 seconds to get it running smoothly. Other than getting low impedence injectors and a standalone, I think you best bet would be to get 440CC with a fuel return if hot starts are a big issue. I have zero startup issues with utec+440cc+fuel return.
