Will An Octane Boost Stop Pinging?

[R33GOD]

my engine light comes on for a split second sometimes at high rev range. will an octane boost fix this? fuel i use is synergy 98 (mobil)

need opinions

[R31Nismoid]

Get it tuned better.

That will permanently fix the problem

[paulr33]

yep get it tuned, the pfc faq in my sig can show you how to sort it out yourself so if u want to try or get the tuner to sort it out

also to note under defaults the engine light flashes for 3 items, not just pinging. read the pfc faq to work out how to diagnose which one it is

afm max, inj max or pinging

[R33GOD]

now that i think of it it dosent make noise when the engine light comes on. i automatically assume it is due to the engine light coming on. im new to this side of things. i will get it looked at in a couple of days.

octane booster is really useless. It will boost octane by .x of a rating.

e.g. maybe 0.3 ron.

IMO, octane boosters do more harm then good, because the majority of them boost octane the wrong way.

[R33GOD]

more harm than good? how so?

[MANWHORE]

I have lost the link when my computer died, but i had a really good explanation article on the way octane boosters work.

By putting octane booster, it won't be the same as buying 98.3 octane fuel. The method they use to increase the octane isn't the same thing.

If you want to increase the octane rating, i'd use tolulene instead.

Octane boosters do help, not really a permanent solution though. A proper tune being the correct thing to do.

seems strange that your engine light comes on i have never had that from pinging, i would say get you timing checked

[paulr33]

Why does my engine light flash when I drive with the PowerFC?

The PowerFC uses the factory engine warning light to alert the user of "upper limit" or ceiling values in the engine systems. Things such as airflow meter max value, injector max duty, excessive knock will cause the engine warning to flash. Usually the engine flash is in a sequence of 3 flashes each 0.5 seconds apart. Should you experience this you should review the hand controller max values (press down when in monitor mode and displaying values to see the max values for each) and consult your tuner immediately. Excessively high knock can cause engine damage. Running on max injector duty can also be fatal so speak to your tuner. Aggressive tunes that are tuned around winter temps/airflow and being run hard in summer may cause these symptoms if the tune is very aggressive and on border line of maxing out the stock components. This is only hearsay but I have seen this from at least one or two members.

See Basic Hand Controller functions and use for information on how to isolate which warning is triggering the engine flash light

If you see your engine light flash whilst driving then goto MONITOR, 4 channel and then select

AIRFLOW

INJDUTY

KNOCK

IGNTMNG

Then repeat the same process and then press UP on the hand controller once you see the engine flash to check the max levels of each sensor you are monitoring. You can then work out which is causing the engine light to flash. On a stock ECR33 with the basic mods fitted youll find that you are maxing out all the factory sensors so in that case I turned my AIRFLOW and INJECTOR warnings to OFF and leave the knock sensor warning to ON. So if you see the engine light flash its a kNOCK warning and should be taken as a true "warning". You should speak to your tuner if you see high knock levels and the engine light flashing. A knock level of 60 is considered quite high.

Like the above post a good tune. But for now use a octane boost.

They say that the nulon Pro strenght is the best one on the market.

[paulr33]

1) identify what it causing the engine light to come on (could be afm, inj or knock)

2) correct the triggering cause (too much ign timing, poor fuel, disable afm max warn, disable inj max warn)

3) notify tuner what you changed / found / adjusted

[R33GOD]

thanks very much guys. i explained the problem to my tuner and he's going to ajust the timing a bit more. when we done the tune the timing was only ajusted 1 degree. bit more should definately fix it he thinks.

thanks once again

If you had to explain that to your tuner.

Go find another one with half an idea.

haha, sounds like he is just going to retard the cas a bit too...

i would be seriously checking the light isn't flashing because the AFM or injectors are maxed as well, can't just assume its knock, unless you know how its setup.

[paulr33]

i bet its inj or afm maxing, mild gtst's making 200rwkw ish max the afm and sometimes inj duty occasionally

but yeah ive seen "tuners" just dial back the CAS cos they cant be f**ked dealing with map looking and map tracert to debug it properly
