to pull the maps out of it, you can open it in Crome.

the maps are ok, the rest of it is crap due to the limited OBD2 support of Crome. This may suck but it's 100% better than no support. :) (it seems that you don't have the OBD2 handler based on those values)

Open this bin in Crome.
Use Export Tables under the file menu to a file of your choice.
Close this bin.
Open a new P30-203 map, manually adjust the map sizing so it matches the P2T maps.
Use Import Tables under the file manu, locate your file.
adjust your options to fit your engine.

OR
since your VTi has the B16a, use the P30-203 map the way it is.

Both methods will give you a decent base map for your engine.
the first method will be closer to your stock setup though.


EDIT: I tried it myself and the export/import option wasn't as easy as I thought it should be.
Here's what I came up with. I copy/pasted the cells into excel and filled in the missing cells by averaging the two surrounding cells.
You still have to adjust everything in the options tab to your liking but at least the maps are there in usable form.

hi

but the rpm of the line map don't the same of the original :?

This works in a specific way in the car??

You have a tuned bin for a P2T-G01??

in the end the actual RPM and/or Vacuum values don't really matter, the main thing is that the fuel/ignition curves are right for the engine.
Since the P2T map had a lot less High map RPM values then the P30-203 map I averaged the two surrounding values and put it in there, then I adjusted it a little to match the curve a little better.

This is not to be considered a tuned map, tuned means matched to your engine, since every engine is different there is no way of giving you a tuned map for your engine.

Hi

Sorry my ignorance but until the size is different the P2T-G01=48K and P30=32K is not meter?

The modification which I need is advance vtec 600rmp or 700rmp and the cut more 500rmp and increase a little fuel for the car not lose power because increase more 500rmp.

If you able make this please help me and if you don’t import send the map with this modification.

If you have a messenger added me filjoa@hotmail.com

Regards, Filipe

the 48k file you posted is the OBD2 bin.
the 32k file I posted is the OBD1 Crome P30-203 based file that works in the more common and versitile OBD1 ECUs.

are you hoping to put the newly modified bin into your P2T?
I appologize for asuming you were talking about an OBD1 setup. :oops:

Ese computador now pode ser modificado, voce precisa comprar um p28, e usar of bin que o relic1 levanto.
Voce ta em portugal o no brasil, voce sabe que tem uma sesao so em portugues aqui, e a ultima na pagina principal do forum.

In english for all you left out people

That computer you have can't be modified, u need a p28, and use the bin that relic1 posted
Are you in portugal or in brasil, did you know we have a section dedicated to portugues, it's the last one on the main page of this forum.


sorry I don't feel like rereading for mistakes
