If you are currently running 298bhp, you will easily top 300 bhp with a full re-map and boost rise. You will have an optimised fuel, ignition and boost set up. I bet the car will feel totally different !! Another bonus of the re-map is better part throttle fuel economy ! Guys who had them fone to their GT4's, had 300 + bhp and 35 mpg :shock:
As far as I am aware, you have a switch on the unit itself that, allows you to switch maps. It's certainly not a seperate unit though !
Yes, you can get it re-mapped very easily. Infact, this will probably be cheaper than the first mapping session as, they will be able to use part of the existing map !
Currently, I am using the OE Nissan ecu. However, I did some research into this a while back when I was looking at doing my GT4. However, the car got written off before the tuner had installed their 4x4 rolling road
However, I will eventually be going the same route as you, maybe with a roller bearing turbo though, (once I have sorted the handling and fuel supply) and I will defo be using the Unichip along with my Apexi AVC-R.
I won't go into the full list of disadvantages as it's not necessarry. All I will say is that the E-manage works out more expensive after you have added looms and boost control and mapping and AFAIK has less load points therefore, isn't as accurate.
The Motec is the daddy of stand alone ECU's but, is way over the top performance wise and money wise for what I think you need IMHO. You're looking at £2k+ after mapping !
It is a similar story with the Haltech although, this isn't as good as the Motec and is a bit cheaper !
In short, if I were you, I'd go for the Unichip. I think they are roughly £600 including boost module and mapping !
