hi there i have a power fc an im getting engine light flickering every now an then it seems to be very high in the rev range on full boost.just wondering if there was any thing on moniter i can check for any thing not quite right i here people talking about nock!!to be honet its just a load of numbers to me an it might aswelll be in swaheli.its just till i can get it checked out after xmas.im thinking i could get summit off the comander info wise

 

yer go into monitor and select knock, then see what level your getting

 

what sort of figures should it be reading.do they change with mods etc.

 

what year is it? Mines a 94 WRX and i get knock of around 30 when its having a hiding (running 1.3 bar boost).
Was told by my mapper thats fine for the year of car.

Still best to get it checked out though just for peace of mind.

 

its a fairly generously modded my97 uk

 

Engine light will most probably be your knock warning or your injectors maxing out, either way you can monitor these on the commander under monitor and select the peak hold function this will tell which it is.

It’s not advisable to drive the car on full load until it’s resolved.

 

its got 550 inj, vf28, fmc, up/down, full decat,apexi ind,seems to be very juicy ,i can rince £20 of fuel in an hour quite easy it does pop an fart alot on the overun,im thinking overfueling poss

 

when i go into moniter is there a specific setting theres like 1-4 and 8 i think they all have knock on em and its a funny graph no actual numbers .is there a special way to get my nock reading,or whats the process for me to get the info

 

fc commander instructions

 

the numbers 1-4 and 8 are how many channels you wish to monitor.

1 channel = monitor 1 reading
2 channel = monitor 2 readings

etc....

 

ok thanks everyone ive sussed the fc now.given it a good hiding this morning and i have a apexi avcr with 3 stage boost,nock info is as follows...@1bar it reads 6-7 @1.2bar 9-10 and @1.4bar 18, is this good or bad?light flickers about 6,000-6500rpm. on the injector moniter it says 100% peak,i looked in the injector settings and 1,2 and 3 read 62.0% 4 reads 62.5% and 5,6 read 100% is this right why is there such a difference between these percentages

 

You don’t want to start messing with the settings menu, injector settings are ok there, and knock seems fine. Injectors are maxing out this could well be the reason for the check light depending on how the power fc was set, you can also check the sensors are working correct in the sensor select A map tweak will also address the above.

 

sounds most likely injector warning.. although that is more a solid light warning rather than flashing..

check the injector warning is on ETC --> FUNCTION SELECT --> INJECTOR WARNING.

however maxxing 550s with a vf28 is some going.. check an intercooler pipe is not loose etc.. and I assume it didn't do this but is now.

Simon[/QUOTE it has done it ever since i bought it from sommerset about 1 month ago found reciept for the remap ,phoned them an they said it was fine when they mapped it,its a bit far for me to go to get em to check out.you was gonna check it out for me a while ago but i had to cancel because i had a few expensive things go wrong at wrong time.after xmas is over with and my bank balance is better i will unleash you on it lol. i was just wondering if i could get any info of fc.is this a bad prob because it seems to flicker what ever boost i run evan if i set it at 0.5bar

 

oh yes I remember now.

sound like possibly somewhere along the way the map has accidentally been alerted.. or there is a pipe leak or similar..

happy to look at it etc..

Simon

 

am i right in saying if the knock reading ok is then im not doing damage to my car?

 

'safe' levels of knock vary from car to car. Only really your mapper can say what's the right range. In general though knock peaks in single figures are pretty much normal for any Scooby, AFAIK. Some are running spot on with knock readings in the teens or even twenties, whereas for others that's too much and indicates a problem.

 

various people an tuners say a my97 uk should be in region of 20-30

 

agree..

if from what you have said we assume it is mega rich for some reason the over fuelling won't be doing it much good.. petrol in the oil etc..

Go into SETTINGS --> AIRFLOW and which number is it on?

Simon

 

1-8 as follows...0.64.1.28,1.92,2.56,3.20,3.84,4.48,512 this all the info i can c on airflow,checked all pipes and boost hoses all seem fine,the only thing i noticed was where the previous owner put avcr in after map just on the drivers side wing near suspension there is a sensor barrel like looking about 3" long with 3 pipes coming out its still wired up but not plumbed in

 

iirc didn;t he fit some mods after it was mapped in wales?

 

i thought he had but found reciepts an all mods have been done before exept avcr.are them figures not right then?

 

when mine was mapped pat the mapper said only worry at 60 on knock and thats mostly due to bad fuel i was also told by another dealer that engine check light is sometimes used as rev limiter light and mine comes on at 7000/7500 in 4th gear and you can display the knock numbers on the screen it tells exact peak figures and resets when you turn ign off ..

 

they are the voltage divisions from the maf section but not the option number it is on..

Simon

 

it varies from car to car and engine to engine..

there is no rev limiter light on the powerfc other than the noise of the engine as the ecu removes all fuel as you bounce off the limiter causing a high knock reading and therefore flashing CEL. . whcih is not what is happening here and is not good to do either.

Simon

 

basicly simon ive been driving it about an the max knock ive had is 18 and the injectors dont max out on every gear seems to be later gears all i wanna no is is it safe enough to drive about till ive xmas out the way and can get you down here... regards scott

 

yeah should be.. I'd just drive it gently.. you have no idea whether the map the garage put on it is still the one on there etc, and the CEL is flashing.. I'd stick below 4000rpm and just drive it part throttle.

the knock agreed doesn't sound high.

Simon

 

ha ha 4000 rpm youve obviously never been in a car with me lol ..that is very hard thing for me to even comprehend haha.im thinking tho ive had the car nearly two months now and i drive hard!! all the time!! apart from emptyin my wallet every couple hours ive not had any probs at all ..this scooby decimates all lol and if not ill have a go

 

lol... hopefully just fuel you continue emptying the wallet for then..

Simon

 

i've got it at about 5000revs, mines caused by lack of fuel so i drive slow everywhere.

I've got new injectors an a walbro 255 so when there fitted it'll be fine.

yours may be the same
