I've recorded base map for the R32 RB20DET AP Engineering PowerFC.

For those that are curious check it out.

I will post up the modified map once its tuned to suit the 3ltr.

If any one has done similiar I would be interested to check out the RB25DET base map.

Or if you have an RB30DET I would be very interested in checking out its map.

At first I had an issue with Idle.

I took the car for a drive so it was nice and warm.

Pulled the plug off the AAC.

Set idle to 650rpm.

Connected the AAC plug back up.

Reset the PowerFC and took it through its 30min learn.

10min idle, 10min idle elec load, 10min idle a/c.

I now have a 100% repeatable stable idle. No hunting and no occasional 1100rpm idle when pulling up at the lights.

Hmmm interesting, mine idles great with the AAC plug out too. I don't really want to reset the power fc yet and loose my settings. Pity i havent got a laptop so i can record the settings straight into xls. I'll have to do it the long way

With mine the trick was to get the car idling ever so slightly under what its set in the powerfc, i.e not going over the rpm set in the pfc.

My idle vary's ~25rpm up and down. Without the AAC plug hooked up it would idle from 620-640 and some times 650rpm. But not going over.

Then it HAS to be reset to do the learn thing again.

I tried simply adjusting the PowerFC's idle setting up then back down again in an attempt to get it to re-learn however it caused MAJOR idle hunt issues and didn't re-learn.

Write down all your maps, post them here and then fiddle with the idle. :D

Hope it works for you. :)

So back to the Z32.. What you are saying is plugging up the Z32 afm does alter the load readings when map tracing on WOT?

Like now it reads load point 19 at WOT 2000rpm. With the Z32 will it drop that to say for example 17 or 16?

My idle was pretty good when i plugged in the pfc after the learn process.

But then i put the z32 in and i've had to add more fuel to stablise the idle at low rpm, It would hunt around and sit at 900rpm all the time. Now its around 670rpm.

I'm thinking of resetting the power fc again and doing the learn process with the z32 in there.

Yes exactly, as the Z32 can read more voltage your load points will drop. For instance, i am using load point 16 between 4000rpm and 5000rpm and im running 18.4psi. If i drop it back to 15psi, it reads to load 14.

Yep thats right.. Did you take notice the before and after with the stock afm vs the Z32?

Mine with the stock AFM will hit load point 18 from as low as 2000rpm when accelerating from a low speed in second.

The reason I'm asking the question is if I fit the Z32 up will it require a re-tune?

I know what your saying Joel.I installed the Z32 a few days before I got it tuned so i can't help ya there.

Here is my tune with GTR injectors,GT2535 11psi :Oops:

Over 12 on the load it's not tuned so any more than 15psi it has a fit and injectors hit 100% duty!!

      Cold compression test after rebuild... should I be worried?

      This is for an RB20DET. Sorry for not including that.

      Welp, this is where my compression lands after my rebuild. Thoughts? I have ~6 hours on the motor.

      Another little story of weird shit happening

      By GTSBoy · Posted

      Well, after the full circus this week (new gearbag, 14 psi actuator on, injectors and AFM upgraded, and.....turbo repair) the diagnosis on the wastegate is in. It was broken. It was broken in a really strange way. The weld that holds the lever arm onto the wastegate flapper shaft broke. Broke completely, but broke in such a way that it could go back together in the "correct" position, or it could rearrange itself somewhere else along the fracture plane and sit with the flapper not parallel to the lever. So, who knows how and when exactly what happened? No-one will ever know. Was it broken like this the first time it spat the circlip and wedged itself deep into the dump? Or was it only broken when I tried to pry it back into place? (I didn't try that hard, but who knows?). Or did it break first? Or did it break between the first and second event of wierdness? Meh. It doesn't matter now. It is welded back together. And it is now held closed by a 14 psi actuator, so...the car has been tuned with the supporting mods (and the order of operations there is that the supporting mods and dyno needed to be able to be done first before adding boost, because it was pinging on <<14 psi with the new turbo with only a 6 psi actuator). And then tuned up a bit, and with the boost controller turned off throughout that process. So it was only running WG pressure and so only hit about 15-16 psi. The turbo is still ever so slightly lazier than might be preferred - like it is still a bit on the big side for the engine. I haven't tested it on the road properly in any way - just driven it around in traffic for a half hour or so. But it is like chalk and cheese compared to what it was. Between dyno numbers and driving feedback: It makes 100 kW at 3k rpm, which is OK, could be better. That's stock 2JZ territory, or RB20 with G series 550. It actually starts building boost from 2k, which is certainly better than it did recently (with all the WG flapper bullshit). Although it's hard to remember what it was like prior to all that - it certainly seems much, much better. And that makes sense, given the WG was probably starting to blow open at anything above about 3 psi anyway (with the 6 psi actuator). It doesn't really get to "full boost" (say 16 psi) until >>4k rpm. I am hopeful that this is a feature of the lack of boost controller keeping boost pressure off the actuator, because it was turned off for the dyno and off for the drives afterward. There's more to be found here, I'm sure. It made 230 rwkW at not a lot more than 6k and held it to over 7k, so there seems to be plenty of potential to get it up to 250-260rwkW with 18 psi or so, which would be a decent effort, considering the stock sized turbo inlet pipework and AFM, and the return flow cooler. According to Tao, those things should definitely put a bit of a limit on it by that sort of number. I must stress that I have not opened the throttle 100% on the road yet - well, at least not 100% and allowed it to wind all the way up. It'll have to wait until some reasonable opportunity. I'm quite looking forward to that - it feels massively better than it has in a loooong time. It's back to its old self, plus about 20% extra powers over the best it ever did before. I'm going to get the boost controller set up to maximise spool and settle at no more than ~17 psi (for now) and then go back on the dyno to see what we can squeeze out of it. There is other interesting news too. I put together a replacement tube to fit the R35 AFM in the stock location. This is the first time the tuner has worked with one, because anyone else he has tuned for has gone from Z32 territory to aftermarket ECU. No-one has ever wanted to stay Nistuned and do what I've done. Anyway, his feedback is that the R35 AFM is super super super responsive. Tiny little changes in throttle position or load turn up immediately as a cell change on the maps. Way, way more responsive than any of the old skool AFMs. Makes it quite diffifult to tune as you have to stay right on top of that so you don't wander off the cell you wanted to tune. But it certainly seems to help with real world throttle response. That's hard to separate from all the other things that changed, but the "pedal feel" is certainly crisp.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      I'm a bit confused by this post, so I'll address the bit I understand lol.  Use an air compressor and blow away the guide coat sanding residue. All the better if you have a moisture trap for your compressor. You'd want to do this a few times as you sand the area, you wouldn't for example sand the entire area till you think its perfect and then 'confirm' that is it by blowing away the guide coat residue.  Sand the area, blow away the guide coat residue, inspect the panel, back to sanding... rinse and repeat.
