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... ;)

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      I don't think the shuffle can damage the turbos. It only happens at low shaft speeds and loads. It's just annoying (to some people - others are tickled by the effect) and it quite possibly reduces spool performance a little bit.

      Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary?

      I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly.
