APEXI POWER FC - Knock / Detonation Issue - How to tune fix? **CLOSED**

[IV73CI]

ok..

had no luck in checking/adjusting the timing ...as i had no chance in borrowing a timing light/gun.

didnt want to buy one since i may only use it once or twice....waste of money.

so ... anyone keen on having a look at my car's timing on this weekend? LOL ..

so i can finally sort the knocking issue and rule out the timing being off?

[IV73CI]

Updated - SOLVED.

Turns out the stupid OEM knock sensor was just too dam sensitive.

car was not knocking at all but was running a lil richer (due to FPR).

other than that - the fhker ran like a mofo on the dyno ... thanks to Benson @ BYP!

now to save up for a Full tune to unleash the potential!

thanks for all your help guys!

lol yeah it happens, really annoying.

my one was exact same, so we just ruled it out as faulty like i said earlier.

power fc knock sensing with stock sensor is bit annoying, i had one on my previous car before this one, and it would read 100 knock just by cranking the car, but nothing after that.

then in my current car on nistune it would knock and fuk the timing into limp mode for a bit. really annoying on cold starts.

Tru dat ...

yeh my cold starts seems to be ok .. and knock occassionally dissapears after 4000rpm ...

check out the end results

the PFC can adjust ignition also, but you need to set it to the setting of the dizzy position so it adjsut accordingly.

With the clunking noise sounds like you might be having some detonation
You may have to do the old fashioned way and retart the dizzy by listening and turning the dizzy slowly. Then just keep under very low revs to drive it to your tuner. (like what Adrian said)


Your injectors should b fine so long as you keep under boost.
I was gonna say you might just have a trigger happy knock sensor but if your hearing knocking that's not the issue then.

how do u set the ignition timing to the dizzy on the pfc?

how do u set the ignition timing to the dizzy on the pfc?

follow the below step.

1)
this is only a temp setting. once you turn off the ignition it will revert back to the orignally settings.




2)
otherwise if you require a permanent ignition tune. then you will need the pfc connected to a tuning software e.g. FC DataLogit for a wide range of tuning values. otherwise it can also be done on the handset but you only get 8x8 map rather than the full 20x20.

Go to ETC / function select
Turn off idle ignition control function (the bottom one)
Return to Monitor screen & confirm ECU output is 16deg @ idle
Then use timing light & set as normal (as you would with OEm ECU & pins jumper's)
Adjust dissy 12mm's to suit
Go back to ETC / function select
Turn idle ignition control back on again.

Thanks Adrian,

i did this, and ignition is dead set 15-17deg ..(mostly 16) at idle.

Got the car checked for the A/F ratio and seems to be just 1 or 2 points above normal. (rich).

but other than that, its not knocking.
