This 'error' isn't really a big deal... so what if your gauge
says 15 psi and the sensor reports ~12psi.

Why, you ask...

the ecu does not care about 'pressure' it wants voltage.
meaning, example: the 2.52 volts signal that used to
'report' only 12 psi and now 'correctly' reports 15 psi
DOES NOT ...

You can keep using the PR3, but you'll have to run open loop.
Not a big issue if you have the time and tools to tune properly.
I have done it, passed CT emmisions.

You'll need a base map that is set up for open loop as you
cannot 'switch' it in RomEditor.

Procedure:
Export your fuel and ignition ...

you can live with the stock FRP if your short on money.

You should get a new fuel....as your asking the pump to flow
nearly twice the volume using 440cc injectors.

Hondata doesn't sell 'chips' per-se.

They sell you the ability to make your own.
(Why give a man bread when you can teach him to fish...)

Hondata has this for both the PR3 and PW0.

This may be fixed in V3, but I am tuning a PW0 and can't
use V3.

Problem: When recording the A/F ratio into the 'grid' all data
is recorded into the the low speed table regardless of
if the VTEC has been acivated. This is fine when tuning the
the low speed cam, but makes tuning the high speed
cam ...
