My K04 custom map opinions please

Did you manage to get the matching ecu as well?

Is matching ECU required or the existing ECU could be reprogrammed? My mechanic assured me that won't be an issue.

Here's a comparable K04 graph from another yon dynamics digital dyno:

Spot the difference

Old ecu can be used but matching ecu would better as you won't have to change any of the engine's original sensors.

R-Tech are undoubtedly very good, but surely you guys need to find someone local to you. What are you going to do when you change some hardware and need the map tweaking or it develops a fault.

In here lies the problem. There is no one else  

As i said not even a Revo/Apr dealer

I think Paul is the same as me, there is no more hardware to go on  

Agree 100% here with James!

The market is very small here and this guy who mapped my car and James is supposed to be the best around here! As what other tuners have commented on my RR graph this might not be the case.

I won't be making any changes to my hardware at all. Just need a reliable and safe map with the components I have on.

I cannot comment on the mapping, I know the tuner who wrote the map.  I think the point he was trying to make was he was trying to map around the audiable surge point of the ko4 with a high flowing engine setup, it's a big job to set the ko3 maps to run with the ko4 and even more so when trying to eliminate the audiable surge point.  A lot of the ko4 conversions I have seen most have not had the surge worked on, they give nice smooth graphs but flutter like mad.
 The torque on the graph on page 1 is basically running with the boost being held back with fluctuations from the ecu PID controllers trying to keep the boost lower than the turbo natural spool profile.
I have ran a BWA engine to the max with a k04 setup, 404bhp 400lbft and the rods held up solid but the rings let go first, same with Dans Leon running a GT series also spat a ring before a rod.


Rods snap when they want to from, silly high peak cylinder pressures from high boost and torque,  casting imperfections, continued elevated engine and oil temp, (the reason track days kill more engine than A road driving)

IMO it would be hard to kill a BWA engine with mapping, unless it was set to spike the boost at 30+psi

What do you mean my flutter nick? Do you mean "boost regualtion" flutter? Cos im sure i got a sh*t load of that on my stage 1 revo.

I think the APR dealer in N.I are called Autotune?  Aaron McConway knows (AaronCupra on here)
