i have just bought an apexi pfc and i have a problem setting it up.

i have the rb25det one, and i wanna know where do i plug my map sensor into?

my engine light is constantly on aswell.

i had a look at paul r33s post and have found out a lot but i just can't figure out wheir it goes and still a bit hazy on what levels things should be at,

when i plant the foot a little the engine light flickers but the knock sensor is sitting on 14 to 16???

Lets take care of the obvious first:

Did you buy a PFC D-Jetro? Cause if you didn't, then the map sensor was a waste of money, you can't run a map sensor on an L-Jetro PFC (Normal kind) you have to run an AFM. The standard AFM will be fine, unless it is being maxed out.

The check engine light only flashes for 3 reasons. knock, injector duty cycle nearing 100% and AFM near max voltage output.

yeah i dont have that kind of pfc, the wrecker just sent me it down from bris and im just trying to put it in.

the denso map sensor i thought id have to use because there is a port for it in my ecu?

The map sensor should be for the boost control kit.

This is starting to get a bit confusing and muddled.

So you have a PFC L-Jetro, PFC Boost Control Kit (including map sensor) and you are using an afm right now?

Was there any other boost control kit plugged in before this, or just the standard?

What mods do you have installed in the car and what kind of power are you making?

yeah i have the stock r33 afm running.

i have a shit 22 dollar boost controller at the moment, i havent put the apexi boost kit in yet.

i have, front mount intercooler,aip pod, intake plenum and the boost controller thats about it for mods.

why are you dicking around with the map sensor then if you haven't plugged in the boost control kit? It's not going to do diddly squat.

If you just replaced the stock ecu with the PFC and hand controller then it should be fine, though it might have a tune on it already not suited for your car...

If the car is stock I would be resetting the PFC and driving it super easy off boost till it has been tuned

Book it in right away and or put your stock ecu back in till its at the dyno!!!!

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
