The F-Super / Formidable Instruction Manual

File:F Super Formidable Manual.pdf

A frequently asked question is "Can F-Super re-code my injectors?"

The answer depends on the build date of your car.

Cars with with automatic transmission and build date 15/06/2003 and later (i.e. 3Y) and cars with manual transmission and build date 15/02/2003 and later (i.e. 3K) can have their injector codes written to and read from the PCM by F-Super but earlier cars cannot.

For the Transit the build date is 07/2003 and later (i.e. 3S).

To determine your car's build date check the characters 11 and 12 on your VIN number.

The Transit has a longer VIN code but the year and month codes are still 11 and 12 characters to the right of the W.

Identifying and Coding Injectors

Notes:

1.The engine should be stone cold prior to re-coding. At least 8 hours since last run.

2. The action of writing the codes into the ECU also resets the fuel trim values that the ECU adjusts by listening to the knock sensor mounted on the cylinder block. Each injection normally consists of a small pilot injection followed by the main injection. Immediately after recoding, the pilot injection will be reset to zero. This will cause the engine to sound more like an old taxi for a while until the ECU readjusts the pilot injections. This readjustment may take quite a substantial time to return to normal.

3. If the injectors are badly worn then the ECU will attempt to adjust out the Diesel knock but there are limits to its adjustment range and after some time it may run up against the limit. When this happens the engine will be put into limp mode and one or more of the following DTCs will be recorded.

P2336 Cylinder #1 Above Knock Threshold

P2337 Cylinder #2 Above Knock Threshold

P2338 Cylinder #3 Above Knock Threshold

P2339 Cylinder #4 Above Knock Threshold

NOTE: The references to Cylinder numbers in all DTC codes are describing firing order and even more confusingly their number 1 is the nearest to the transmission, so using the Cylinder numbers in the pictures below the DTCs translate to:

P2336 Cylinder #4 Above Knock Threshold

P2337 Cylinder #2 Above Knock Threshold

P2338 Cylinder #1 Above Knock Threshold

P2339 Cylinder #2 Above Knock Threshold

MAP, BARO and Boost Pressure

F Super is very good but the Live Data screen has some problems with the stated units:

MAP has units of kPA but the actual values shown in the F Super window need to be multiplied by 10 to be correct. (e.g. At rest the MAP should just read atmospheric pressure which is about 100 kPa but F Super reads 10 kPa)

Likewise the BARO reading in F Super should normally read about 1000 mb (millibars) but actually displays about 100 mb.

So, if you wanted to know what your Boost Pressure was:

Boost pressure in psi = ((10xMAP) - BARO) / 6.895

e.g. If the MAP is reading 23 in F Super and BARO is reading 100 we can say that the boost pressure is:

230 - 100 = 130 kPa. i.e. 18.85 psi

1 bar = 100 kPa.

1 psi = 6.895 kPa.
