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 ?

  • 2 weeks later...

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?

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 !! :dry:

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.

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?

Edited by r33_racer

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)

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.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
