Yes they doShoot a email off to tony again and ask him what the pulse width is for that tune your runnin. If hes comfortable tellin ya/us, then you can share. i know sharing tuning stuff can be touchy so i dont want you steppin on anyones toes ya know, he will probably help you out and explain it as well anyhow. it may be too much for that pump is why everyone is wondering what it is. 60 overs like to drink diesel
LLY: 85 over cp3. Sounds like a ford
- Thread starter PAT
- Start date
Pilot injection fuel flow rate = 0.6 average and 1.9 max.
Pilot injection timing = 22.6 average and 50.8
How do those numbers sound? To much? To little?
Yes, tony does all of guys tuning. So send him a log or make sure tony got it. In the end it is tony tuning your truck so he will fix or what needs to be done to make your truck run correctly that way if he does have the log he can see what is actually going on that way you can send him the ecm.
Injectors balance rates checked out ok.
I wish there was a way to take the pump out of the equation and making sure its a known good.
I was curious to that question just from my basic understanding of tuning. But tuning isn't my strong point.
Sounds like stock to me , but what you posted up doesn't really help
When you add bigger injectors and leave pilot fuel mm3 the same you are adding a lot more fuel on the pilot shot
However if he is saying it's not enough I would disagree
As the bigger pump will add more fuel also
Pilot fuel shot can make a rattle if there is not enough.... I actually shut mine off at anything over 1000 rpm and tuned out the rattle with other fuel tables
If you look in the timing calc thread there is a pilot timing calc also posted
If Tony is tuning your truck gEt him involved and he can fix it
More easily said than done. Him and guy are busy men and hard to get ahold of. I'm damn near about to acquire a stock ECM from a junk yard and get a friend to tune it for me.

Pat,
I called you back yesterday, your VM box wasn't set up so I could not leave you a message.
I vehemently dislike texting and would rather talk to you in person.
I have PM here, always online, I have email as well at my web site.
I am not hard to find, and even with a log it is doubtful that it will get resolved that way. In my experience many people confuse timing noise, fuel pressure rattle, pilot rattle and other noises when modified CP3's and 60% injectors are in the equation, a log doesn't give me the same information as when I am seated in the truck in real time.
If I were to get some seat time in the truck it would get resolved in under two hours and you would be on your way, you just need to get the truck to CT.
Sorry it is inconvenient to have a locked ecm, but I am not a high volume/low priced email tuner who sends out tunes like a kid with a Napster account. It's always quality over quantity, I don't need cheerleaders, fancy web sites or expensive advertising, my business is all referral and word of mouth.
Most of my tuning is custom through diesel shops,usually high profile trucks.
Ask anyone who has brought the truck to me or flown me out to the shop to tune the truck and you will find that I am very good at what I do.
Try me today, but it would be much easier to bring the truck to me.
Tony
See that's what i didnt get why he said more though with my truck it rattles an ive simply given up trying to fix it as ive tried messing with pilot timing, pilot fuel, main pw, rail pressure, reg mpa tables, just cant get them to be quiet.
I know on my truck if you pull 40% outta the pilot fuel thing will hardly run an rattles like a bitch found stock pw in pilot sounds better and runs better but still has rattle??? So the injectors are all foinf to Exergy to be checked out balanced and flow matched ect to see if that helps
Mine doesn't rattle anymore. It sounds normal at idle now. I'm just trying to get the Rp to stay up.
Would need to see the whole thing to say. Just saying if your CP3 is holding 26k with the fpr disconnected, and when driving it's commanded 21-2xk, and the pump is matching commanded, it would seem to me like the truck is making the rail pressure it's being commanded to.
Timing will give you the "powerstroke" noise to a degree, but anyone who's heard a durmax with no pilot injection would swear its a powerstroke.
You can listen to hear if the pilot injection turns off when you go WOT on the highway. If you don't hear the "powerstroke" noise get any louder when you go WOT, that would lead me to say pilot injection is either off or not enough.
JMO, I'm no expert tuner...
With FPR disconnected will running the truck to WOT be a bad idea? I just want to see If the cp3 can keep up with the injectors under full demand.
