Hi all doe's anyone know if a r33 auto computer will run in a stagea?

We were thinking since stageas are soo detuned you could gain by using a 33 auto computer.

Doe's anyone know if this would create any problems or could this quite possibly work?

Both the R34 and R33's have VVT on the intake cam. The difference is the R34 system is infinatly variable in adjustment, where the R33 system is on/off.

However, this doesnt seem to be an issue as Cyrus is running and R34 GTT powerFC in his R33 engined manual converted Stagea.

I dont know if the tiptronic/not argument has much basis either, as the box still works like an auto, essentially they are both the same, with the tiptronic feature being an add-on to the standard auto box....understand what I am trying to say.

Id be curious to see what would happen if someone tried it.

OH, on another note, there are a few sensor changes from R33 to R34, for example R34 RB25DET's have MAP sensors which tell the ecu how much boost the car is running, also a few of the pinouts on the R34 are different to the Stagea, namingly the injectors are on different pins (hence the car wont run plug out/plug in with an R34 ecu)

I was talking to Beastian last night, he said he plugged his R34 PowerFC into his car, and it worked first go with nothing changed. It didn't drive as his car is still auto, but the engine worked. I don't think the injectors are on different pins if this happened

Three of the injectors are definately on different pins, but they are just mixed around with each other, this is why the engine still ran, the injectors would be firing at the wrong time, but the timing is so close, it still ran under no load.

If you drove it like this you would definately notice it.

Also I have found out through someone in the forced induction section, and confirmed it with the R34 service manual and Stagea S2 service manual, that the VCT is basically the same between the R33 and R34, it's ON/OFF. The only difference is the R34 has been designed so it comes on alot more smoothly.

There are a few sensor differences aswell, but from studying the service manuals, they won't make any difference to the running of the engine. I think they are mainly to do with the more intricate R&R mapping that R34's have.

So are you saying you can plug in a R34 GTT Powerfc into the S1 Stagea (auto or manual, it makes no difference if the auto has the MV shift kit), fire it up, and have it dyno tuned, and away you go?

Or is there more to it then just that ?

Definately has to be a manual Brendan, Power FC has no facility or connections to control the auto box unfortunately.

I'll actually be starting my conversion this weekend, and the PFC will be going in afterwards.

I just wanted to plug it in and see what happened, Theres been a bit of talk about the R34 version not being compatible with the S1, and modifications being needed. I knew it would work because Ska's seems to work fine, and I thought I would be the next guinea pig, and work it out for myself. What I have found is very promising, and it's looking alot easier to acheive than first thought.

Once everything is finalised, I will gladly post my findings, and answer any questions.

Power FC in auto R33 RB25det does work

with MV Automatics shift kit

........... trust me ! :P

I'm almost certain, specially after looking at an R33 service manual, that they have a separate Auto trans ECU, unlike the stagea which is incorporated into the engine ECU. Thats the only way it could work.

Maybe it would be possible to put an auto ECU from an R33 into the stagea to control the transmission, and run the engine from a Power FC or such.

More than keen to share my findings mate :wave:

I'm pretty sure that I remember reading in an issue of HPI a while back they did a feature on Auto's with MV Automatics. And as well as the shift kits and other internal mods they do for autos they also have a little black box they've made where it bascially takes the control away from the auto ecu and makes it manual. As in it won't shift itself anymore you need to use the auto shifter to change gears (like 1st, 2nd, D = 3rd etc). This would explain what Tangels was saying. If this were the case then it wouldn't matter about using the PFC as long as it can run the motor, you'd just have to get used to changing gears with the auto selector.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
