Legacy BE5/BH5 RevB and RevD B4/GTB ECU pinouts

[DJB]

HI All,

as stated above, I'm after the pinouts for the Legacy BE5/BH5 RevB ECU pinouts.

I converted a Legacy Heritage (Twin sunroof, full leather interior + EJ25NA) to A GTB using a Blitzen front cut.

I'm now wanting to tune the thing so I'm contemplating rewiring the ECU plugs to take the new updated OpenECU tunable ECU. There are heaps of guys here in Aus that have successfully tuned there own RevDs with a tactrix cable and a wideband.

It's either that or I rewire the ECU and also convert to single, VF34PE20 FTW.

Cheers

I believe the sensors changed between the revision B and the revision D. I know for sure that the MAF is different and I've been told that the D has an extra MAP sensor etc.

Sooooo, it probably isn't possible to just rewire a revision B engine to use a revision D ECU. Besides, the base tune would be out since the compression ratio differs between the two engines too i.e. 8.5:1 for the revision B and 9:1 for the revision D so tuning it might be a little more complex?

I'm aware that the sensors changed through the models, and that is will be difficult. That doesn't phase me though, my PhD is more difficult and intractable, this problem space is tractable.

I'm an electrical engineer by trade and design custom wiring looms for all sorts of gear, as well as translator boxes, so I can design custom hardware and looms for this no problem. All I need is the above listed ECU pinouts (and sensor voltage range representations).

I can also get my hands on a cheap RevD Intake Manifold, including injectors so if push comes to shove I can build it that way, I firstly need the pinouts though.

Ok cool... You're not going into it blind. Actually you may need the manifold as it did change and the two revision D's I've seen have pink injectors... The B probably has greys or yellows.

[DJB]

B has yellow side feeds, D has pink topfeed. I'll just scale the injector duty cycle to start with and tune from there.

All I need is the ECU pinouts.

im am very instereted in putting a Rev D ECU into my rev B B4.

If you sucessfully change it over i would be keen on 'purchasing' your knowledge! ;D

Best of luck!

I have to ask: why?
