Just fitted a Power Fc....Problems need help

[darrinspencer]

I just fitted a Apexi Power Fc and Hc to my 95 GTST manual

It is a brand new unit

When i started the car, it is or sounds like it is not running on all the 6 cylinders

Anyone have an idea what is wrong

Thanks

Has it been tuned

[darrinspencer]

No

the car has FMIC, pod , exhaust, fuel pump and a few other things

My understanding, it sould run on the base map, if running standard boost etc.

[Robo's]

It should run fine on the base map, maybe re-initialise it!! Check that it is set on the correct AFM.

Mine ran fine on the base map and i have a Z32, 2530, 17psi, exhaust and all that.

If is missing, try adding fuel through the inj/ign menu to see if thats the problem and if it is make this correction onto the map.

the base map is designed to get you from home to the tuner. I would highly recommend a tune

[SAMFISHER]

If you don't have the optional boost control module then make sure that option is turned off. The default setup looks for the boost controler and will not run properly if you don't have it.

I turned it off before I started it

Even tried turning it back on to make sure I had it the right way.

The would not run more than 2 seconds with it turned on.

I have refitted the factory computer and the car is running fine.

Like Robo said

re-initialise it

Like Robo said  

 

re-initialise it

I am sure i tried that last night at about 11.00pm

Will try again to make sure tonight

Here is the default setting for a RB25DET. I may be slightly different to yours but its a good place to start.

You will not be abled to get to all of the setting from the FC Commander.

Have a look at the defaults for a RB25DET

you will not be abled to get to all of the setting via the FC Commander

get someone to tune the car.you cant run the car without tune.you can try chapman&chapman.Andrew is very good for it. 07)33914522

good luck mate

[darrinspencer]

Tried the re-initialise last night, no change, still not running right.

Looks like will I have to wait for the tune once a I get the cams and injectors in.

[R33vit]

The PFC should run the car fine out of the box,yes you do need to tune them but there set up with a base map that will run the car ok.

If it is second hand maybe the program has been changed with the Excel software and that is why the re-initialise doesn't fix it.

Check to see if the AFM settup is the correct one for your car.

Did you go throught the 20min idle time with a load on the battery.

Is the case of the unit earthed out? (read in another post where this was the issue)

[darrinspencer]

The unit is brand new

I have not have enough time to play around with the settings too much

Will try on the week-end

Dose the casing on the ecu need to be touching the metal body of the car (earthed out)??

I mounted the ecu using the factory bottom ecu bracket, but it is held in and isolated from the body with the velco strips that come with the PFC

I have the stock AFM at the moment with a Apexi pod, so the it should be set to the first R33.... AFM option?

I did let is run for approx 20min, it farted and carried on a bit thuo.

Turned air cond on etc.

darrin,

had the same fault when fitting my pfc, missing on one cyl, changed back to standard ecu and running on all cyl. The fault was the main connection to the pfc not being completley home and therefore causing the miss. Check the main connection to the pfc.

Good luck.

Thanks DoubleD

Mine turned out to be the same problem

I found when you do up the bolt that holds the plug into the ECU, it causes the plug to curve at each end causing it not to make a good connection. This can also happen with factory ECU aswell

Solution- I used cable ties which went around the whole ECU and plug and pulled the plug in tight at each end.

[SAMFISHER]

Same thing has happened to me since I replied on this thread!

I was worried it was a coil or something.

Have put std ECU back in but have only had it idling so far.

Has the problem re-occured with you guy's or is it now fixed?
