Rb26dett Power Fc Running On Rb20det.

[47une]

Hi all,

After installing my turbo and all supporting mods onto my RB20DET I was on the hunt for an aftermarket computer. After a fair bit of research, Power FC it was, but bugger me if I was going to spend the ridiculous amounts people want for an RB20 Power FC. So I looked into getting an RB26DETT Power FC modded to suit. After finding out that it could be done, I found the cheapest Power FC I could find (wrong idea) from Nengun. After a 3 month wait for it, it finally arrived. I then sent it straight on to BoostWorx in Adelaide to get modded and the RB20 map put into it.

The RB20 computer loom needs some modding before the RB26 Power FC can be plugged in, from the description it looked rather easy and a 10 min job. WRONG! We figured out a few problems with the wiring, it said to join different wires together in the computer loom, the problem was there was actually no wires in the RB20DET loom where they wanted us to join the wires. So we had to remove pins with wires that weren’t being used (aircon and automatic transmission wires) and put them into the correct spots that we needed to join for the RB26 computer.

After triple checking everything, we then hooked the battery in and watched for a minute to see if anything was going to fry, then put the ignition on for a minute and waited, then started the car…….it started first go!! Ran very smooth too and the Power FC was showing all the data it needed to!!

The only thing that I am checking up on is if an RB26 knock sensor will fit into an RB20 because the RB26 Power FC reads a lower knock when on the RB20. Say it is reading 30, it should be reading something like 60 because it is actually pinging, so at the start I will just have to make sure that it is reading nice and low on the knock reading.

It is booked in for the 11th for its tune, so cant wait for that!

All up including the modding the Power FC has only cost me about $900 so I am rather stoked.

awesome work, its always great to have a car fireup the first time after doing some ecu work!

[robots]

How did u remap it for the rb20 ?

[R31Nismoid]

you dont, you just re-wire and tune...

As far as I know, it does have to have a RB20 map put in, it would be done via a datalink with saved maps on a laptop. But I am still waiting to confirm what BoostWorx actually did for me by "modding" it.

[HKS_R34]

well done mate. As far as the knock reading goes, I would also be sceptical as to the true reading.

[47une]

Oh, I know its not a true reading, so now I just gotta find an RB26 knock sensor and see what I need to do to make it fit.

There are four guys down here in Hobart running RB26 Power FC on there RB20's, all modified by the same bloke and im about to put one on my built R32 RB25de+t and when its done I will post up all I know and a bit of a how to thread

haha yeah mate, I would hate to be paying someone $900 just to add their special map and change some settings. It was $900 plug in (except for the wiring I did)
