Pfc Question

[fletch63]

Hi guys,

Just had an intake manifold gasket replaced on my 33 GTR.

Now it it is running way too rich and needs retune.

I haven't had it long and suppose that it was last tuned compensating for the air leak.

Now it is running way too rich and after 10km or so the plugs become so fouled up it is almost undriveable.

It has a PFC of which I know little.

My question is does anyone know if there is a quick way of changing a setting or 2 on the hand controller,

or is a complete remap required.

Just so I can get it to the tuners reliably (and prior to that to the exhaust shop)

Otherwise its plugs out before each trip and then at the tuners.

Any help would be much appreciated

Cheers

what heat range plugs are you running? if they are 7's then going to a 6 (hotter plug) might be a short term solution until you can get it to the tuner

Settings

Ign/inj

Turn fuel down a couple but not too far.

Drive it gently to the tuners

When ignition is turned off it will ignore those changes and go back to how it was

Thanks for the reply

But what exactly does "turn fuel down a couple" mean

My battery is flat at the moment so can't check hand controller,

and I know Ign/Inj settings section, but can't picture the screen

So how specifically would I make the adjustment

Keeping in mind it as a temp fix until proper tune

You can adjust fuel or ignition across the entire map. You will see how far you have adjusted it and the new figure it is currently running at.

Its pretty straight forward. Prob turn fuel down a couple (from 100 to 97-98) for example and see how it is.adjust more if necessary. Just be sure to take it easy driving there
