PFC Map X & Y axis?

[GunMetalR33]

Hi guys,

I have been making some minor changes to my ignition map as my tuner had it running way to much advance so I am cutting it down a bit. I have been using the map tracer to locate the areas on the map that are used and noticed that the tracer never goes passed cell 11 on the load/boost axis. I guess this is due to the AFM maxing out (am i on the right track?).

Any way my question is this:

Has anybody out there got some sort of conversion for the load axis...

i.e. a conversion for the p1, p2, p3, p4 on the load scale etc etc...

A conversion for the rpm would be good as well, i.e. n1, n2, n3

I realise that these are linear and that you probably dont need to know what PSI level they map to but it would be nice to have the info.

Sorry about the long topic...

The rev axis is in 400rpm increments from 400 rpm to 8000rpm.

The load axis is the MAP sensor input, you should be able to line this up with your boost gauge.

Thanks for the reply. That is very handy...

Load Axis : ofcourse I can line it up with the boost gauge. Should have though of that myself

thanks again.

hi, load on cell 11...seems low to me are you using std AFM? What about turboes? what boost are you running? Is it a GTR R33? All these can affect what cell you end up in at certian boost levels?

On my R32 GTR, std AFM's, highflowed GTR turboes, running 14psi I reach cell 15 on load by 3600rpm to give you an idea anyway. But remember that the AFM measure total airflow not boost (although thay are associated) and as I have larger comp/turb wheels my turbo may reach cell 15 at 14psi boost but yours may not if they are std GTR turboes.

That aside please answer the above questions first and maybe myself or other here will have a better chance of helping....

Old post revive.

What I do find strange is my Rb30DET with the PFC ALWAYS dips to load point 19 at WOT on 12psi at 2000rpm. It holds load point 19 all the way through the rev range.

It did this on the RB20DET afm and now also the Z32 AFM.

The Z32 AFM didn't 'appear' to change the map trace at all. ?!?

Strange. Has any one else had experience with the before/ after map trace with the rb20/25/z32 afm?

You sure have an inquisitive mind:) Have a Becks and lay down Cubes...may you dream of 25G power:)

And off thread... that TD06 ran a 10cm housing on the RB30.
