Ecu To Run A Modded Rb25

[bretto]

ok ok settle down ive done a search and cant quite find an answer to what i want to know....

ive got a rb25 with 264 cams, cam gears, fmic, 1.2mm metal headgasket, fpr, big fuel pump and a tdo6 20g (with 12cm exhaust housing) ready to bolt onto the side of it. what i want to know is, the engine is in an r32 and is still running the rb20 retuned ecu. can i get away with running that and using an safc with some bigger injectors or will this not work so well and should i just bite the bullet and get a powerfc??

i dont have the funds now for the power fc so i would have to wait till i could put the turbo on. im chasing about 250 rwkw, ive been told i could get a bit more because i ahve the bigger cams but because the internals are stock id rather not risk it.

any help would be great as im stining to get this turb on the car asap so i can have a bit of fun!!!

cheers....brett

You've spent all this money on those goodies but you havent saved for the engine management system? Priorities in the wrong place i'd say.

Save for the PFC, it'll be worth it!

i actually imported the car from japan as it is

believe me powerfc would have been in front of alot of the mods that are on the car if i had been doing it myself.

remap or powerfc, cant go wrong

also suspension and tyres should be on your list

i suspect traction will be a big problem

as soon as i saw this topic i knew everyone would of said PFC...

I also say PFC...

powerfc ap engineering model 1400 with hand controller + tune 350

rb25 powerfc modded to work on rb20 1000 + (mod work $unknown)

remapped rb20 ecu 400 tuned

main advantage with pfc is you get the hand controller and it can be adjusted easily and quickly, plus you get knock sensor, airflow and injector warnings with the engine light. also adjustable rev, idle

as long as they haven't f**ked with the wiring too much to get the rb25 in there, powerfc..

what loom?

VCT disabled?

These are the things you will need to find out before you decide really.

[bretto]

vct has been disabled as it has the 264 cams so thats been taken off. its running the modded rb20 ecu and the loom to the ecu is rb20 going from ecu to engine then it has the rb25 engine loom. i have no idea why they have done that but everything under the bonnet came as a surprise to me so i cant complain to much.

it has some very grippy tyres on there atm and is running hks coilovers so traction at this stage is controllable although the twin plate clutch is really being a handfull to drive. anyone wanna swap for a button that will hold the power im chasing

[bretto]

something else to add, the fact the powerfc comes with a handcontroller means nothing to me as im not a tuner and therefore wouldnt touch the thing with a 10 foot pole anyway for fear of changing something and stuffing up the setting on it.

[paulr33]

the interface on the hand controller is very easy to use and has a few very handy features. you dont need to be race engineer or tuner to use it. it can be useful to make adjustments to correct excess knocking, adjust timing and fuel, change idle and monitor all the essential items. you will only risk the engines safety if you make stupid adjustments, and you would be foolish to do without knowing what it did.

so it is a VERY handy device to have, once you have one and use it, youll never go back

Don't think of it as a tuning device. Look at it as if it is 8 digital gauges, it's good value for money for that reason alone. It's also a great diagnostic tool, just like the Consult is for a Nissan dealer.
