How Much Can A R33 Rb25 Handle

[Cubes]

If you want to go another ECU I think the Wolf3d v500 is a nice option. Its ~2k (plugin) + tuning.

Do remember the PowerFC is 1k BUT it doesn't have boost control, the wolf does.

Mildren Race Engineering are the SA mob to see for the Wolf.

The Wolf3d V500 is everything I would want in an ECU.

Sequential Injection

6 Coil drivers

Closed Loop o2

Boost control

VCT control

High/fine resolution load/rpm points

and the list goes on.....

My uncles a systems designing microelectronic engineer who has worked on a few drag cars, I will ask him what is the best application for street driving modifications and I shall get back to you... that wold3d looks freakin sweet tho... but as you know you can buy a plugin for power fc for boost (AVCR plugin)

Yep that is what I was getting at. By the time you add the rather featureless uncustomizable PowerFC Boost kit for ~$400that brings the price up to $1400 odd. You then need a Z32 or Q45 AFM thats another few hundred.

Is it worth the extra $300-$600 for the Wolf3D. If I had the cash at the time I would say yes, purely for the multiple map ability and datalogging should you want to hit Mallala.

As the Wolf can run MAP pick up a stuffed AFM for next to nothing or use your own and knock the guts out of it, leave it sitting in its origional position for when the mr. policeman pops your bonnet.

dont forget to add the cost of the hand controller to the wolf if you want to start adding boost controller kits to the cost of the fc

i think their about 4-500 ?

also tuners can be harder to find , for instance only 1 WA i think

but feature set looks good and the software looks very nice

The best ECU option for anyone's car is the one their tuner is most familiar with. Period. It's more about 'the tune' than it is 'what's being tuned'.

Out of interest, Apex got their GTR to run 8's with an AFM'd PFC.

Thats exactly it Adrian.

I have no doubts about Mildren Race Engineerings tuning ability to top it off they are top blokes.

Last time I was around there they had an interesting dead stock looking VS v6 commodore pushing out 320rwkw through a pair of turbo's on 12psi. It had P plates stuck on it.

Shaun on the other hand.. He just has that nack where he can tune almost anything. BUT I know what he will recommend Paul. The PowerFC.

[Pauly33GTS-t]

The Djetro PFC?

My uncle just emailed me back, hes got 1-2 spare EMU sitting at his work which he personally designed for a ca18 dragger. hes gonna let me try it out when i get my turbo. I will post up pics of it when i get to try it out.

[Cubes]

Being off a 4cyl it may not be suitable.

The RB's are notorious for killing coils when they are run in batch mode. You NEED 6 coil drivers.

Djetro.. yer but the bang for buck is lost.

Every ECU has its place in the market.

Paul.. The other thing with the Wolf... Drop a cheap couple hundred auto in to it with a manual shift kit and run that quick 1/4. Then claim that high 10sec 1/4 with only 400rwhp not 500odd.

[Pauly33GTS-t]

yeh u told me that i think in one of ur pms, i always knew that a properly configured auto box via suitable ecu will perfect change everytime, no proper drag cars are manual... I dont want to lose "the fun" tho, so im stickin with manual.

my uncle said its reprogrammable and can drive 6 coil drivers. need a cheap laptop to configure it and thats it. hes givin it to me and tuning for me on the deal that i design a new website for him so thats ok by me.

Not 100% sure if you meant it has 6 coil drivers or it is able to drive 6 coils *in batch mode*

Question him if it has 6 coil drivers..

Being able to drive 6 coils is irrelevant as almost all ecu's are able to do so, in BATCH mode.

Don't use batch mode coil drivers on the RB's or your asking for trouble.

If you need the coil dwell times etc drop me a PM.

[Pax-Ottomanica]

That wolf ECU sure does look fkn sweet-o-pies..

[Chris_R33GTSt]

Im looking around for an aftermarket ecu at the moment. PowerFC does look very nice and im tempted to try find one, but what competition is there: Im planning to build up a street car for occasional track use so it needs to be able to run all of the nice stuff the factory ECU runs + A bigger turbo + supporting mods and it has to be smooth and return good fuel economy. I know a lot is in the tune but im guessing a lot is also in how good the system is as well. What other options are there?

[SirRacer]

PowerFC is a good computer when you want minimum effort to get a decent tuneable ECU. I've heard patchy arguements that MAPs are better than AFMs - I've given answers to the AFM vs. MAP debate already SirRacer. I'm not going to join the arguement, but I vote the MAP sensor without hesitation.

ST mainly tunes PowerFCs, no wonder he's pro PowerFC.... if he can't tune other things, why would he tell you to go with others?

There are quite a few cases around the place of people getting over 500whp on stock internal RB25s, though at least a thicker head gasket is well recommended.

robin at torque dan. hes also a link dealer . you should know i cant understand soichi for the life of me

people also say with a power fc the afm runs out of resolution. a q45 can go to a good 500rwkws from what ive been told

The wolf is a sweet computer, the only real thing i can fault it on is the boost control, being that it isn't closed loop, it takes a while to get a good curve on the dyno, then on the road the boost changes as the ramp rate does, it may be fixed on the new ones though?

[SirRacer]

what do you guys think of this (bar the 4 coil drivers)

retail for around 1200nzd

so a good option for a street car doing 300+ rwkw is to buy a PFC and get the D-Jetro Super Suction Kit.

[CAT_SPEW]

Might be a bit off the topic, but seeing as everyone is talking about ECU's...

I've currently got a Haltech E6K, one of about 4 prototypes made if I remember correctly. Anyway I've got a set of nismo 740cc installed and my car will run like shit when started cold for about 5-15 mins of driving.

I have been told by a few mechanics that it's the fact that my injecters are too big and the computer can't handle them. Also that it is "batch firing" 3 injecters at once.

My questions is, would upgrading to a new model Haltech fix my problem with a good tune?

[Adriano]

Have you tried playing with the cold start enrichment?

Its not a bad idea, but you really dont need a djetro at this power level, i would stick with an AFM for better drivability.

the stock afm will run out at decent power levels. for 300rwkw get a VG30 its sufficent for those poser levels and fits on quite easily as aposed ot the q45.
