Engine light flashing - Power Fc

[Blade]

Got my power fc recently fitted and tuned.

I noticed my engine liught flashing when accelerating hard in 3rd 4th or 5th.

I wasnt sure what it meant, read a few previous threads and i realised its knock warning.

I didnt have my hand controller plugged in, just plugged it in then took my car on the freeway accelerated from 4th all the way to around 5000+rpm saw the engine light come on agian.

Read the knock value and it was 96.

Question Is: is this really bad? Did the tuner do a bad job..? should i take it back and get a retune?

Thanks for any advice

i just read some previous threads...it means "im knocking, therefore back off" why do you have to back off...? i cant hear it pinging...well ive never heard a car ping i know its meant to sound like metal on metal but all i can hear is the spool

What should i do to stop it...?

I specifically asked the tuner to undertune it so i can safely hammer it without worrying! Has he done a bad job if im knocking?

Take it back

The tuner hasn't tuned it safe enough to take in to considerating different operating conditions.

Thanks for quick reply. It cost me $400 to get it tuned, would the tuner charge me that again for a re-tune?

If its knocking due to the lack of tuning then No you shouldn't have to pay again.

If its knocking due to the failure of a fuel pump then chances are all you will have to do is drop in a new fuel pump, then give the afr's a quick look over to ensure they are still all good.

Fuel pump is brand new

Damn, what a hassle i specifically told him to undertune it so i can always hammer it...i dont care if its running 10 or 20 less hp just to be on the safe side

Get a new tuner

I might be wrong here but I have always been told a knock reading of 60 is the safe limit and anything over is running a risk of engine damage

The tuner i used is supposedly highly reputable in Victoria.

I seriously cant afford another $400 on a re tune. im sick of spending money fixing SHIT NOT DONE PROPERLY IN THE FIRST PLACE.

I thought it was weird when he was only on the dyno for 40 minutes...he must of rushed it.

Dont stress to much, the exact same thing happened to me, i took it back free of charge until he got it right....

I to went to a well know tuner... but the customer service has been quite good, now my rwkw has one down a little but on a 33 degree day it was knocking around mid 20's and the light hasnt come on since, even in the heat loading it up in 5th...

I always ask for a dyno print out showing AFR's.

Not that it will help bad ign. map setup but still its one less concern.

it wont cost you a cent.

Its not a "retune"

its a slight adjustment on a map point which will take all of 5 mins.

Just remember what RPM, what speed, what gear. And that will help yuor tuner find the point even faster if they know what they are doing.

I've had mine back once, and needs to go back again.

Its the way of tuning. On a dyno you CANT get it exact.

Doesnt mean the tuner is crap at all.

Bit hard to replicate 170km/h+ @ 7500rpm on a drag strip (thats where my knock was)

Take it back if your worried about it, he was most likely just richen it up in the mid range and top end or pull a bit of timing out
