So I Bought A Car With A Pfc

[Ionos]

Hi all,

I bought a car that came with a PFC & Hand controller, tuned and everything.

However, when I go into the options on the PFC to look at the settings everything is pretty much blank. What's the deal?

I know it has to be tuned because it has a larger turbo and injectors fitted, and runs great. If it wasn't tuned it would run terribly I assume.

What am I missing?

If all of the values in the ignition and fuel maps are zero's it means that whoever tuned it last locked the tune so you can modify it yourself. Talk to whoever tuned it or see a reputable and experienced PFC tuner.

Nice, quick and easy answer. Thanks!

Does that mean that if I take it to another tuner, they won't be able to change anything and would have to start from scratch?

I don't think so, mate. Cross that bridge when you come to it though. Tuners with the right laptop software can be quite tricky when they need to be

a good tuner can unlock it with datalogit

Try ringing the dude you bought it off.

I think it';s a 4 digit code or something to unlock.

But yeah, a datalogit can turn that option on/off

Maybe borrow someones

Tha Mafia knows alot about DLogit so maybe ask him

Hey, you don't need codes at all. They are just check boxes that the tuner has to untick. Either that, or leave them ticked because the lock out options don't apply when you have a datalogit attached.

You can't change them with the hand controller though, you absolutely need someone with a datalogit to make any further adjustments.

Cool, didn't really want to tinker myself was just concerned that I'd need to start with a brand new tune if I wanted to make any changes.

Thanks again all.

Re-opening this one with another question.

I'm getting the occassional knock which I have tried to diagnose using the Ign adjust option, however it doesn't seem to do anything. Even when I've set it to -10 degrees it makes no noticeable difference. Would I be correct to assume that this option does not work when the tune is locked?

Thanks again.

Would locking the tune also disable the boost control function?

Update - I think I know why the bastard is knocking.

Was talking to a mate at work and mentioned the problem, he asked me what fuel I was using - I said Vortex. I was under the impression Vortex is all 98 octane, but as it turns out most Vortex in South Australia is actually 95 octane. Shite!

BP Ultimate on the next tank which I imagine should fix all the problems.
