Edition 30 : APR Stage 1 review
john_o:
Hi Msportman,
I dont have a new dyno yet , but will be at the 6th June 2009 meet @ superchips so will get one then :happy2:
I have noticed though that JKM graphs vs others should very different curve styles for the same car, so smoothing factor and load for the run are a factor.
I considered all options before making my choice.
Power delivery for APR / REVO / GIAC seem similar and enthusiastic in delivery from low rpm
Bluefin can be adjusted to remove this , although the newer (non torque limited) maps seems to be just as enthusiastic as others now.
This is just one factor in your choice , make a list of the criteria and itll be obvious which one is for you :happy2:

22 psi peak , 17 psi hold
310bhp @ flywheel
280bhp @ wheels (roughly?)
376 lb/ft peak , 300 lbs/ft plateau

376lb/ft!!!! Does it really put that kind of torque down to the ground in low gears? I can see why you say it pulls like a train in 6th, with that kind of torque it must really shift!
Do you have a boost curve to go with this power/torque curve? I would be interested to see how the car is boosting. Especially around that massive torque peak early on.
I have always favoured the bluefin maps due to their more reserved, smoother torque curve's. Might give the 2wd chance to start rolling.

I think you know which company I will be using with the ease of changing programmes and I want cruise control fitted in any case. Have you found a need to upgrade the brakes?
What about the suspension...I personally like it but perhaps some subtle lowering would be good....wondering whether just springs will be any good...eg HR or Eibachs?
Got a WALK kit on order.

Quite a big spike at the beginning....maybe the RR set up as John states or it's APR's mapping....how does it feel on the road John?
My APR Stage 3+ did the same.....definate spike initially then dropped back and smooth delivery. Bluefin maps look much different on 'their' RR!! :surprised:

er in the dry kindof , in the wet er no :signLOL: judicious use of modulated foot use reqd...
boost follows the characteristic of the power curve tbh , peak 22 psi, dropping to 17 psi quickly right up thru the rev range. not sure what boost is at redline......
er yes suspension , tyres , WALK , LSD are all considerations at this level of hp
