Hey Guys,

I just want to say that now I know why everyone goes wild over changing engine management. A mate of mine has Minimal mods - Exhaust and Front mount only.Boost has not been increased. He got a Apexi Power FC and got it fully tuned up and the car seems like a whole different beast now. Im not too sure if this is normal but just thought it was strange how engine management would change the car so much with minimal mods.

well yeah i mean with any mods it will throw the computers reading out so getting a FC or whatever will correct them plus a full legit tune will definetly see an increase.

id say its normal

wind up the boost a little :D

that said, the gains to be had from going to a stock ecu to a remap/PFC are huge compared to the gains from going from a remap/pfm to another aftermarket ecu.

Obviously there's some hardcore ecu's out there, such as autronic and motec but for the money spent they will only give slight gains over a well tuned PFC. they will however do a lot more and a better job.

Folk on SAU always say: Mod list...1. Intake 2. Exhaust 3. ECU

It's right up there with the basics. Just think...factory ECU's are tuned to run on 100 octane fuel. We only have 98 octane in Oz. That's just one reason to modify engine management.

nothing really. just a cheap way out. doesn't really do much a factory computer can't do.

but couldn't expect much more from a "after market computer" that uses a chipped nissan ecu. basically what dr. drift does.

not any more. and if you have a rb25 forget about it.

meh, $495 for a R33 remapped chip isnt bad price IMO. thats what Yoshi advertised......

add $25 for soldering in, and a dyno session (best if you already have a safc to make more adjustaments)

with rb25 engines, the gains are very significant with a remapped ecu or powerfc because the standard ecu's are so aggresive and sensitive in their protection parameters, you barely need to fit an exhaust and the boost increases a few psi and you are hitting the limits, even if you can't feel it, throw it on a dyno and the graph will typically be all over the shop with dips and holes in it.

    • They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required. 
    • I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.
    • I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something? 
    • I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation.
