I recently sold my dodge cummins and made the switch to a 2021 ecoboost. Was wondering if anyone has any insights on when the 2021 will be able to be tuned?
I think I may have been reading my maps wrong which has gotten me confused. Concerning the maps on the tune, boost pressure fuel quantity limiter table for example. Is that scaled in absolute...
the resason i keep refrencing absolute pressure is because i found a calculation online for mass airflow. it uses engine size, rpm,map,iat and # of cylinders. when i run the numbers from my log at...
i definlty understand more boost isnt always the answer, 35lbs was just a random number i pulled out of thing air. their comes a point when your outside of your turbos map and its just blowing hot...
my thought is this map is used by the ecu for a target airflow. which the ecu use absolute pressure to bring the airflow(based on a calculation) to the target on the map. because the calculation...
Do you know what else these tables effect? I have found a calculation, so I can set it so my turbo won't go above 35psi theoretically. But will it throw anything else off?
I have been doing some forum searches since i got home from datalogging. One thing i have found is refrence to adjusting estimated airflow tables. What is strange is not everyone does that? ...
I'm trying to diagnose a boost issue. My truck will not go above 23lbs of boost. I'm trying to decide if its tuneing issue or hard parts? I started datalogging the "turbo wastegate Dc" and it...
Thanks Jim! this worked great
found this in another thread, is this what you tried?
Adjusting the speedo is easy. You take the stock size tire. Change it to inches to make it easier..
In my case 05 Dodge ram diesel came...
what did you end up using for tire rev? I just switched to 35s and calculated 593 tire revs per mile which is over double of the factory 250?
Wonder if he would just sell the switch and harness with out the tunes?
I can log pilot injection volume and post that up later
thanks for the help
I have been paying more attention to my data log pilot timing values versus maps. rarely does the 20 degree offset work? so either correction tables are always in play or the 20 isn't quite right?...
Jim, its possible I don't really know what "injector rattle" sounds like. I have a diesel rattle type sound under light load/cruise that when I get aggressive it smooths right out. I just assumed...
05 six speed all stock
I use that math pid and my truck basically idles at 0. You need to make sure you log the two pids the math equation requires or it wont work
I want to begin to tune out injector rattle. My truck seems to have it all the time unless im under heavy acceleration. Befor I begin pulling timing out of my main tables, I was wondering if I...
Any idea why it's off by 20?
I read those posts, was just little nervous just adding or subtracting till I get to a number that matches my map. Because I do t know if that's accurate or not?
I have been data logging my pilot injection and the numbers seem to be very different then I'm expecting. Even after considering correction tables, which I admit I dont quite understand how they...
I log it on my truck, it's a 2005. You need to load the os patch
I was logging some 6th gear 100% throttle pulls from 1600rpm low load to 2100rpm . I noticed I had hit an air density limiter, when looking at my tune I have baro limits maps maxed out @ 144.973....
For those of you more experienced in tuning multiple trucks. Do you have different strategies for tuning a manual versus auto truck, all things being the same between the trucks except...
No white smoke, this all started after the truck sat for over a month in a body shop. Truck looks great but came out with some gremlins.
