PFC Fault code finding

Post by Mike N »

I'm just wondering, how do you check for error codes on an APEXI PFC ecu - its a rev 3 version.

I'm not sure the pfc has error codes as such, I know it does have a sensor check menu though

like he said no fault codes as such but has a menu that will show id any of the sensors are out of wack
If you see an MR2 with a raised engine cover, the bottom line is it's probably faster than your car.

When I was having problems I put the original oem ecu back in and found the problem, fixed it and swapped the ecu's back again.

Thanks so far,

The proplem I have is the loom was modified from Rev 1 to rev 3 PFC with speed density and std rev 1 sensors whilst at mapping.

I dont have a PFC hand controller.

Does anyone have a rev 3 PFC hand controller in the Kent area to do a test?

The issue I'm having is that the power tails off and goes flat over about 5k rpm although it still revs to 8k as before.

Does anyone have or has used the FC DATALOGIC from NZ?

I have a Datalogit permanently installed in my car, I'm pretty conversant with FCedit (the PFC mapping software)

FCedit still doesn't have any fault codes or diagnostics capability though, if that's what you're wondering

Rob, Interseting - just found this.........

I could not copy link unfortunately, but here is an edited extract, it says it does the same as hand controller and more?


Works with all Power FC versions (No restrictions imposed on the number or type of vehicles tuned)
The FC-Edit software does all the things that the hand controller does plus much more
Log up to eight 0-5 volt analogue inputs
Connect to any 0-5 volt Wideband 02 Sensor and log A/F ratio
Firmware Upgradeable
Full size fuel and ignition maps (20 x 20) instead small sections
Lock /Unlock Apexi dealer protected maps and settings
Map trace and ghost trace
Rescale/Expand maps for high RPM and/or high boost applications
Adjust air temp correction tables
Saving and loading complete maps and fuel and ignition settings
The Power FC commander plugs into the FC-Box so you can still use it
Adjust the threshold for flashing the check engine or cat light for injector and knock warning

I am considering buying an FC Datalogic as I dont have the hand controller and people ask high prices for used ones! These look useful for most things.

datalogIT not datalogic.

TBH, unless you actually plan on mapping the ECU yourself then there is no requirement for one, and the cost of them ($299 usd) is much more than a used hand commander goes for (£125ish), also, for the Datalogit to be of any use you will need a wideband o2 sensor if you don't already have one, which would be another £150ish

really, it depends what you're wanting to do, ideally you would have both, the hand commander is a really useful tool for quick checks/rough changes and is an invaluable multi-gauge for everyday monitoring (knock especially) whereas the datalogit is good for mapping and pretty much only that - unless you want to be driving about with a laptop powered up on your passenger seat all the time!!
