What Should I Tune Rb30det With ?

[felixy69]

hello

i am Garry is building me a RB30 bottom end.....then i am putting it together here in canada, we have no experience in tuning RB30, so i would liek u guys help !!

what sorta thing should i look out for ?

what's the difference in tuning compare to RB26 ?

what computer is the best for tuning RB30 ?

what sorta things should we look out for when putting it together with rb26 head, i think we got the basic RB30-26 swap down..but there might be little details that we missed

the engine is going to sit taller, will it clear the hood, i know with rb26 and my t78 turbo it almost hits the hood, will i have even a bigger problem with this issue ?

anything other rb26/30 to BNR32 info would be a great help to us !!

thanks again !

if it was me (which it's not)

apexi powerfc

then if that wasn't available

autronic or motec

but that all depends on what tuners are in your area, whats the point of a moetc if no one locally can tune it ?

Its about an extra inch on the deck height, so everything there up will sit 1" higher then it currently does.

thats it...no one can share more info ???

[paulr33]

what other info do you want/need?

[azzr32]

any decent ecu will work as good as any it all depends on the tuner.

you can have the best of the best motec ecu, but it will be no better then the power fc or what ever if you dont have anyone that knows how to use it to its full potential.

if i was you find a really good local tuner and use what ever they recommend.

hi

thanks for everyone's replay

i understand that a good tuner beats a good computer !

and i also understand that not every computer works good with every engine set up

so my question is what computer works the best with RB30/26 with single turbo and no MAF

thanks ...

but thanks everyone for replying it really helped alot !

It sounds like your building a bit of an animal and cost comes second.

If you want the best, get a Motec ecu that is suitable for your engine.

Sure you pay a little more for them, but you are getting the best, used in all kinds of world motorsport engines.

what ecu's can your tuner tune?

[SirRacer]

go and ask your tuner what they like and feel most comfortable with then go and buy that

[felixy69]

what ecu's can your tuner tune?

basicly my tuner said, they do not reccomend Power FC......and told me to go for Raytec..but i called tomei and they said, since the Raytec is still very new, tuning RB30 with Raytec is not recomened, i have HKS f-con V-pro right now. but no one can tune it !!

motec is just too expensive and same as Haltec..

help

your tuner does not recommend powerfc....is he an auto mechanic, or a mower mechanic by any chance?? (personal joke, mate of mine is a mower mech and doesnt like powerfcs, works as a mechanic now. haha thought there might be someone else like him around canadia.) didnt mean to be an insult, my apologies.

Powerfc has got to be one of the cheapest, and easiest a/m computers to use. Its excellent value, and im sure almost everyone on here would agree with that.

Power Fc is good for your average modified street car, good for cold starts and cruise etc, not the choice for a race car which it sounds like you are building, thats why most people on this forum use Power FC. Only a handful have race cars, mainly street cars. I have used Power FC, Microtech, Haltech, EMS in customers cars, different applications for each one but all have there pros & cons. Apexi D-Jetro may be the go as it uses MAP sensors over airflow meters but is a shit too tune. I am building a similar engine, RB30/26, HKS T51R etc and am definately going to run an Autronic ECU. Much more flexibility for tuner and gives you the ability to trim individual injectors to get afr's perfect in each cylinder with the aid of EGT's. Its a set and forget deal. This is the heart of the operation, rather spend a few extra dollars here than risk the engine. Youl find that alot of the time on this forum people will advise on the cheapest rather than what works better, alot are only speaking from there own experience as they have ony owned a car with the one ECU or boost controller, ie $22 bleed valves etc. You get what you pay for. In the end your tuner is the person you should listen too. best of luck.

Yeh 2BNVS had to swap ECU's to autronic cause the PowerFC couldn't cope with the 30/25

[r33_racer]

Well ill know soon enough, we will be using powerfc pro in the 25/30 in a few weeks when it gets tuned. So i guess that will tell the story.

He also mentioned that motec and haltec are too exxy for him, how is an autronic compared to say a motec in price? I thought autronic were not too far off a motec?

ive used EMS and microtec i would recommend both for the 26/30, if you where in oz i would say go for the microtec because with my experiance there is more people who know how to tune them well compared to EMS. they are both well priced (around $1500au)

i dont know alot about powerfc but the tuners i know dont recommend them so i didnt use it.

but all these ecu's are useless if your tuner cant use them, so i say use what he recommends or find a tuner who can tune microtec(or whatever)

[BezerkR32]

They are not cheap but are getting more computer for your dollar. Have to compare apples with apples.

But if he is worried about price of Haltech, it might be too expensive.
