Well finally i can look forward to the drive to RB motorsport tomorrow to have my car mapped with a apexi and remove my Nismo ecu.

Is it wrong to be so excited? I am really wondering if i will see any difference in the car at all.

Is there anything i should be asking/doing while im down there as i am staying with the car.

yes, ask for a before and after rolling road printout to show what you have gained in spending lots of money on an aftermarket ecu.

you're well within your rights to be excited - I had exactly the same thing done last week - Power FC into my GTR and fully dyno tuned - made 283kw (1bar) @ all four hubs on a stock motor with cams + exhaust. It's a whole different animal to drive now :)

The only thing I forgot to ask for was flames on overrun/gear change - it used to do it big time on the factory ECU (as it was over-fuelling) but now it's all a bit boring :(

I did the tuner a favour by - removing the centre engine cover (as they'll want to set the base timing off a plug lead, not the induction loop), leave the kick-panel off so they can easily access the computer - oh, and make sure it has a full tank of whatever petrol you intend to use - mine went through about half a tank on the dyno. It'll make them well mad if they have to run and get gas for it!

Well just got back home now and full respect goes to the guys again at r b motorsport.

I am definatley a happy chap as i have found out that it has aftermarket cams to add to the list of its other extras.

R B Motorsport dont have a dyno so power figures are unknown and all mapping was done on the road which i personally think is the best way for drivability.

The major difference i can see in the car is the low down drivability i can now cruise in town in 3rd/4th rather than 2nd. Obviously the car does feel quicker now especially the accelration.

I am now limited by my std afms so when i have some cash i am going to upgrade to z32's/nismos.

All in all i am very happy with the result.

^^ hehe, that's some baaad humor - good to hear you are pleased with the tune - I'm a little hesitant about it only being tuned on the road - and it would be interesting to see how much more power you could get with hub dynos (i.e. dynapacks) and a tuner who knows how to use them.

I assume they attached det cans, AIT sensor and a wideband to do the tuning?

TBH i have no doubt on the ability of rods mapping by just using the roads i am sure many in the uk will agree with me.

I am going to try and get booked into a dyno so i can see whats going on. the trouble is most around here are just 2wd. or is there some way i can run my 33gtr in rwd.
