Thread: FORScan Transit software - works on Defender!

OK, I've done a little more playing but not the greatest result. I decided to try the pump learn procedure, figuring a) worst case no harm and b) it might improve engine running (not that it was running badly).

All started OK, and the procedure went through the injector "Temporary learning" step no problems. It then ran the "Adaptive learning" step, and got about 45% of the way through the procedure in total, but stopped with errors - the sort of errors were initialisation error, engine temperature, short to VBATT, and loss of connection to the ELM adaptor. Note that these errors didn't occur on each run, but across the three times I tried the procedure.

In any event, it has left me with a fault/DTC code of P268B - which I think means that the pump learn procedure didn't finish properly and needs to be re-run. This is the only DTC I have - no others, and no yellow "check engine" light.

I was connecting via a bluetooth ELM327 device - my suspicion is that it might not be a reliable connection and drop-outs may be causing the error. My only other guess is that my SCV (which is the original one) is not working properly and so the relearn can't complete (this is a total guess - and note that the car is running/idling/starting perfectly, with no abnormal fuel consumption). And, even with this P268B fault code, the car appears to be running fine - it idles very steadily, and a short drive felt normal.

So, thoughts welcomed. My initial thoughts are that I will get a wired/USB ELM327 lead and try that. Bluetooth is probably OK for monitoring but my suspicion is that it's not a good option for a service procedure.

My final question: does anyone have a point of view as to whether I should/not drive the car before completing the pump relearn successfully?

Has your ELM 327 device been modified for the FORscan configuration?
From reading up online since I saw your thread started earlier today, I can see a standard ELM 327 interface needs to be modified (rewired via a switch) to decode highspeed data.

I downloaded the app but didnt proceed as I dont have a modified interface

Yeah I suspect that'll be it... certainly hope so! Should have RTFM a bit more...

I have now hit eBay and ordered one of the FORScan-modified units. Will try that and report back.

i did the same thing but with a GAP diagnostic tool on the iPhone. Did a pump relearn and it would not complete. Tried it several times to no avail. After that exercise it idled rough, lots of smoke on start up and lost a bit of power (still ran fine once you were moving and staying in the torque band). I took it to my regular mechanic and he persisted with the pump learn using his commercial diagnostic tool until it stuck. I've been instructed to never mess with the pump learn (chastised like a naughty child).

Yours seems to be less affected than mine. If it were me i'd drive it but book it into a mechanic to do a pump relearn with a commercial diagnostic tool.

So this is turning into a bit of a saga... and I keeping thinking there is truth in the if-it-ain't-broke-don't-fix-it adage...

I received my modified ELM327 dongle ex-eBay. But, no joy - exactly the same errors as with my bluetooth version. Admittedly the dongle wasn't the same one recommended by the Defender2 folk, but I didn't want to wait for a part out of the UK (probably should have - a so-called "local Melbourne" part took over a week...). So, I am in the same situation - car running OK, but logging the P268B code.

I'm booked into Pickards next week to have them do a learn procedure. That'll either tell me I have a fault in the car causing the issue (i.e. they won't be able to do the learn), or I bought the wrong lead.... Will keep updating for reference.

My final thought is that my car is remapped, and so I wonder if that's part of the problem - it's an early BAS tune, with the android app that DOESN'T have the pump learn utilities. However, I think I will wait and talk to Pickards before reflashing and running the pump learn.

OK, not winning. Really should have left this alone.

I flashed my remap back to standard, after advice from Pete Bell (BAS) that this is the path he normally takes prior to a pump learn. Then, the pump learn and pilot correction completed successfully, using FORScan and my new dongle. So far so good.

But, then I noted I had DTCs indicating that the EGR was not responding, AND that it was stuck open... The BAS remap, of course, does not exercise the EGR - at least not on my version, so the EGR had been idle and presumably coking up for many months... And, the car feels WAY down on power. I only drove it a few metres up the hill from home and back again and then parked it - didn't want to do any more damage.

So, next job is to remove and clean (and hopefully not replace) the EGR. It presumably opened on command of the standard remap, but then I guess it jammed, open, of course...

My learnings so far are:

- FORScan does seem to work, with an eBay-available modified ELM327 dongle
- If remapped, probably a good idea to flash back to standard before you do a service routine with FORScan
- If remapped, and you have an EGR delete program, AND your remap doesn't run the cleaning cycle, you really should periodically flash back to standard to exercise the EGR (as I had been told, but ignored...)

OK, will keep posting until I run out of feet to shoot myself in. Tips on EGR removal (which looks a pain in the butt) appreciated.

Maybe you should go for a long drive to heat up the EGR so it goes through its cleaning cycle?

Yeah, thought about that. The chukka-chukka sound you normally hear on the standard tune when you shut down the engine is the cleaning cycle - I'm not even getting that. So I think it's pretty stuck, and I'd really rather not drive it with a stuck-open valve - it really feels asthmatic...
