Can A R32 Ecu Be Used On A Rb25det

[13thracer]

is it possible to run a series 1 rb25det on a r32 ecu i only ask because the 25 is in a s13 and is allready not using the few things like the speed dependant power steering and the vct has been removed from the engine there is also a few other bits and pieces that were removed.

in short is it possible as i would like the option of a cheap remappable ecu

[Adriano]

Definately possible, just need to make sure the cas is the same(or use a r32 one), and check out the injector impedence

is there anyone that knows exactly what has to be done to make it work

[R31Nismoid]

By the time you purchase the parts, ECU... and change a few things over to make it work.

You'll be close in terms of costings to PowerFC and that sorta thing.

It can be dont, there was a thread about it some time ago, although i cant remember exactly what it was about but i remember reading something.

Try the search button, might take ya 15mins to wade through some threads but you never know

[Craved]

you might be thinking of the thread asking if the rb25 ECU can be used on the RB20 ..

there are injector pins outs different.

also look at the Power FC FAQ on pauls site

it has the pin out change over GIF that i think cubes made with the differences in teh pinouts.

if your realy keen to do it, start in there

just use the RB20 loom and AFM

so long as the AFM and CAS are RB20 units, it will run.

The AFM will simply read more air flow and compensate with more fuel... so if you have turbo injectors (370 compared with the RB20's 260's) youll find it will run too rich.

i found that the knock sensors are the same units, and by visual inspection the CAS looks to be the same (i will know for sure in a couple of days)

oh and just note that the RB20 ecu has no provisions for the NVCS so you will need to go to Jaycar to sort that out;.
