AP_PowerFC_RB20DET_Base Map.xls

[Cubes]

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.

Thanks Cubes , would it be possible to see the set up maps . I don't have any of this yet .

Thanks A .

Setup maps?

[Robo's]

Off by memory, the ignition maps look pretty similiar to mine. Fuel is way out but depending upon if the setups are different each will be different.

[Cubes]

Robo,

With the Z32 bolted on.

Was it as simple as selecting Z32 from the menu and the car would run perfectly as it did prior??

Or did it need a little cleanup due to the Z32 showing less voltage for x airflow.

[Robo's]

Choose option 3 on the Air Flow meter types. Also im still playing the voltage signals to try and get a stable idle.

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.

[Robo's]

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

[Cubes]

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.

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.

[ferni]

ok i'm gonna ask the dumb question - what do all the numbers mean. the red value is RPM i'm guessing, but the table - whats the numbers and whats the colum/row values?

[Cubes]

X Axis are the rpm points.

Y Axis are the load/airflow points

[Cubes]

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?

[R31 POWER]

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!!

[Cubes]

Thanks.

I'm interested in the ign. timing pattern.

EDIT: Oh.. no ign. timing.

[benl1981]

Is anybody able to post up the default Rb25 maps?

Thanks

[paulr33]

i have the apexi defaults from rb25 PFC version 5.0

[benl1981]

Can anyone post them here?

Thanks
