How To Fit An Apexi PFC Plus Update. Fuelling Issues?

[ro284]

It\'s not necessary to remove the intake manifold, there is access to the bleed screw, it\'s not easy to see it, to get at it there is a cut out in the intake manifold just in front of the rear lower fixing nut, just above oil filter, from this nut feel forward about 10 mill in towards battery, best felt for with a small screwdriver, all done by feel, you can adjust it with the engine running,
Good luck Bob

OK. UPDATE.

Got the Apexi PFC and Commander installed. Old ECU out. New one secured.

Reconnected battery. Switched ignition on. Initialised all data... I THINK...

Went to ECT - NEXT, Intialise Data - NEXT, Cursor left to YES - NEXT. Turned ignition off and then back on again.

Cranked the engine. Engine started. Let it idle for 10mins. Then turned on rear screen defroster for 10mins. Then the AC on for 10mins.

And think that\'s it. Bit puzzled though as there wasn\'t very much rough idling during this process. Only a fraction to what I thought it would be like. Thought it would be really rough from what i\'ve heard. There was also no confirmation upon entering or completing learning mode on the commander - not sure if there was meant to be.

I then turned off. And now in writing this. I haven\'t taken it for a test drive yet as not sure i\'ve done it right. Seems to idle OK though.

Max water temp reached was 95 degrees and then pondered between 95 and 89 degrees throughout with fans coming into play.

Inlet temp around 64 degrees towards the end.

Injector duty around 4% on idle.


And I THINK knock is displayed as a bar. Never reached a quarter of the screen length I think.

I also forgot to adjust the bleed screw before I began. Is this necessary to do?

Just out of interest... how would I reset the unit and go through the learning mode again? This time I would adjust the bleed screw to make sure.

Any ideas why the idling wasn\'t rough? Only noticeable roughness really was when I turned the aircon on. It rose sharply and then gradually settled down to a lower value.

Sounds about right. I think it depends from car to car how rough the learning can be. It\'s was\'nt rough on mine so nothing to worry about mate. All engines stumble a bit when the air con is first switched on due to the extra load from the compressor, as long as it idles nice with it switched on then i would leave it. Take it out for a nice blast and feel the difference in power, with the cat in place it should be safe to blast it.

good work, let us know how the car runs now..

Initialised all data... I THINK...

Went to ECT - NEXT, Intialise Data - NEXT, Cursor left to YES - NEXT. Turned ignition off and then back on again.

is this necessary to do?  The brand new apexi will have been initialised at the factory wouldn\'t it?

I did the idle business, though....

Will it have saved itself?

[Tiger_kpt]

Dazsir... mine wasn\'t a new unit. Mine was second hand. Nearly new, but used for around a month. Guy bought it for his UK spec AUTOMATIC RX7 FD. They aren\'t compatible with an auto trans though. Trans keeps on slipping.
I just re-set it to be sure thatit was at factory spec when installing on mine.
 
Am at work now. Drove here. Went for a blast lastnight too. Runs ever so smoothly, more responsive and more powerful. Was a bit hesitant to boost it, but... it loves it! Well chuffed with the unit. Can\'t rate them enough now i\'ve tried them out first hand. Very clever bit of kit.
 
Anyone know what sort of knock readings I should be getting shown up on the Commander?

[strange_days_uk]

60 knock is the highest you ever want to see.  More than that possibly = det proper and you will get the flashing red light on the dash.

Anything below 60 is ok, although I wouldn\'t wanna see more than 30ish normally day 2 day.

Good to hear you got the car running well, well done!

The PFC is certainly one of the modifications i have on my wish list later down the line. Just out of interest, after fitting the PFC did your car produce any large puffs of smoke on start up - like it would do if it was clearing itself out?

[Tiger_kpt]

Hmmm. My Commander doesn\'t display the knock as a number... it displays it as a rising and falling black bar that rises left to right accross the screen. Although that is on the 8 channel mode. Is it displayed differently on another channel format?

[Tiger_kpt]

Hmmm. No no puffs of smoke really. Only white smoke upon start-up until warm - due to the temperature and weather. Condensation. I think. And hope. lol.
No noticeable puffs of smoke - blue or black. Can only be a good thing I hope.

I dont know if this is any help, but its an extract from the PFC Commander manual..


Dont know if thats any help with your knock readings?

[Tiger_kpt]

Yeah... I have the bar graph display. So how can I convert this into a numerical value so that I know it isn\'t going above 60 and preferably under 30? Is there a seperate function on the PFC Commander for this?

[ash]

Kpt

Have you got the commander manual, in there it shows you how to convert/display numerical values in various display modes. If you havent i can email it to you?

you can set a peak mode on the commander , I have 4 channel setup with peak enabled, so I have another set of numbers highlighted in black background on the right side of the screen, so I have the bar graph constantly moving but with the peak value in numbers displayed to its right, I see quite high knock values when taking my foot off WOT 90-100, about 30-40s on WOT. On the decell the high numbers are are caused coz my car is extremley noisey due to the bridge port and straight through exhaust. On Slightly modded twins up to 60 value knock is passable, but this value is not gospel do not use it to tune, actual real knock your engine wouldnt survive too long

Excellent on fitting Maybe I\'ll get mine fitted soon, had one for a year now without fitting!
