my r33 apparently is limited at 7000 but i can fly past that to around 7800 is the futrthest im willing to take it. Also has no speed limiter.. and the tune is really good (see dyno sheet) so im guessing its got a chip? anyone know what types of 'chips' people put in these ECU's?

If you purchased the car from Melbourne chances are it is chipped with a Dr Drift chip which removes the speed/rev limiter. they are/were going cheap and many owners brought them. the guys that work at the performance shop I go to said they are nothing but trouble (as one was in my ECU)

I wouldn't recommend trying to redline your RB20 or a piston might go flying through your bonnet!

there is nothing really wrong with that chip except for the redline. There is no point in increasing the limiter on a stock turbo RB20. I had one in my last car and the before and after dyno chart showed round about a 10rwkw increase.

Its just a pretty generic map that most folks can d/l anyway.

btw rev limiter is not removed but raised up to about 8200rpm

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
