What does this light mean?

Power FC is in which I bought second hand, and just running of the base map... The guy I bought it of, had already done the start up procedures, so pretty much just took out the old ecu, and replaced it with the Power FC...

Everything runs fine, however this light comes on and stays on... What does it mean and is it a good or bad thing???

I am going to get my car dyno'd but not till Janaury (Christmas presents are expensive!)

So can anyone identify my light problem?

umm, that is not good. That's the check engine light, which usually means you have no oil pressure or something has gone drastically wrong with your engine. In your case however, with a PFC fitted, the PFC uses the check engine light to tell you that your engine is detonating. Sometime the value at which the PFC will display the warning is set very low, this could be your problem, either way, check it out.

So using the hand controller, how do I go and change the setting so the light is not on??? ie moving the warning up? And what should it roughly be set at?

It was fine when I had the stock ecu in, there was no light thingy.... Should I be driving round the next month or so like this????

If its running of the base map, it shouldnt be detonatin right??? I mean, I took it for a spin, everything seemed alright, ie engine temp, boost stayed constant @ 7psi still

Its a base map tuned for japanese ignition timing on japanese fuel. I wouldnt go around flogging it too much, but I am sure other people will disagree with me.

Does the light flash? The Power FC warning lights flash a sequence of codes, not stay on solid. Check and make sure that the boost controller option is turned off on the power fc. While the car usually doesnt start if this is on (and you dont have the PFC boost controller), I have heard of some starting and just showing the warning light.

At the moment running optimax on the car.... The light does not flash, it just stays on constantly.... So even though its on, and Im running off a base map, is it still stable to drive??? Everything seems fine when i drive it

Im guessing it would be stable to drive over the next week or so... I think ill get my dyno done earlier now...

If it's on and stays on, regardless of how you drive, chances are you still have the boost controller function turned on in the PFC, and don't actually have the boost control unit.

Ok, ill go check that out now.... Did anyone else ever have this problem??

Those are the reverse EL dials.... I bought them from a Group Buy off here last year sometime...

Anyhow, the dials are gone now, and im back to the standard dash, but have red LED lights in it, which makes the numbers light up all red at night. Matches the amber defi's :P

this ones easy, your running a pfc with no apexi boost controller right?

if u check yr settings you'll prolly find the boost control is set to on.

THanks, yeah that was the problem... Had the problem ages ago when i just tested the PFC in the car... But now its all tuned, and making some healthy figures... ;)

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points?

      I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.

      Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
