Does anyone have any info on Ficm tuning? Where is a good place to start when messing with the Ficm
I would like this info as well.
You adjust the pulse width in the FICM, just like any other diesel. Increase the pulse to make more power, you really only need to touch 2 tables.

whats your thoughts on a timing calculator for the 6.0, i havent seen one yet and was going to make one modeling from the early dmax's understood that we are huei vs common rail, but we are still dealing with pulse width vs pressure vs timingQuote:

factory "supplied" ficm file shows injector pulswidth maxing at 1670us, dmax guys are running upwards of 2900us-3000us on max effort tunes, looks like we might be leaving alot on the table, and im sure this has been discussed somewhere, but i wonder if the ficm values are the hard limit, or if the pcm "mass fuel desired" wins?
As far as I know the ECM just asks the FICM for a quantity of fuel. The FICM uses the pulse width map to determine how long to hold the injectors open. If there was a limit it would be in the FICM.Quote:

Does anyone have the procedure to enable FICM? The software isn't giving me the option to license the FICM (4.2.12). I have read that a relay needs to be removed to stop potential damage to the injectors. Is there a procedure that everyone is using for tuning these diesels out there? I have read a lot here but, there doesn't seem to be the same for diesel as there is for gas for a step by step tuning. Thanks for any and all help.
Update* I guess diesel support is still in the Beta. Still not sure about the FICM relay?
Hook up your cable and click read, then click gather info. Should show you three different controllers the ECM the FICM and the TCM. Pick which ones you want to read either only one or all or whatever but depending on what you choose you will have to licence the file accordingly, as when you go to flash you dont have a choice it will flash all of the controllers if that's the way you read them. I like to do them individually and build separate files.
When flashing only the FICM that is when you need to remove the injector relay, I only had to do this once because I built separate files and only needed to flash the ecm multiple times, so plan ahead.
The software was hanging on to my original scan. All set now Thank you.
So what would be the rule of thumb here...Does one add say 5% or 10% to the entire table or what exactly? There is a lot of this stuff that I don't quite understand yet.Quote:

Or is it a FICM table that is also expressed in the ECM? Also, what does the x axis represent, its -50 to +150 as I recall.. I don't have the specifics of the axis, I have MacBook and on the Mac side of the hdd so I can't open editor right now.
I dont know how to add an image. but its diesel fueling- main injection- inj. pulsewidth (ECM 3687). stock is 40 um across the board. microseconds
That table has to do with the high pressure oil system from the looks of it. IPR (Injection Pressure Regulator). You don't need to mess with it.Quote:

That would make sense I guess since its all actuation pressure related. It misleading labeling it fuel Inj. Pulsewidth
For all those who don't know, spoofing the FICM does work within reason. However there are potentially severe side effects. Be careful, make changes in moderation and always datalog what's going on. That includes connecting to the ICP on the analog cable inputs so you can see what it's actually doing.Quote:

I'm not saying don't do it but if you do it for a customer you better damn well know what you are doing.
Kill the adpatives in the TCM file and tune oncoming and offgoing pressure tables to compensate for no adaptives.Quote:

Update your software and its now there, I had eric add it in for all trucks 03-16 awhile back.
im probably blind but can you point me in the right direction for how to make sure my tune is using stock calibration for icp sensor, im teaching myself tuning starting with my 05 6.0 ps and i am modifying an sct performance canned tune while comparing to my stock file etc and since ive paid for ficm licensing i want to tune right instead of icp fooling.. also im assuming cheating fuel density would cause all the same problems?Quote:
