Just a quick update, I did get all the correct injector information in my tune and made a run. Things are more stable as hoped, I collected quite a bit of data and applied it to this tune. I have...
perfect than you for the patience and lesson. I had confirmed my fuel pressure so all that is good, I had added a gage to make sure that wasn't the issue. Depending on time and weather I will...
This is information I was looking for, something I had done or an issue in the tune. I now know what I have done so I can move forward without wondering why things went off the rails.
I am back...
ohhhh well that does make sense, I had read about the static pressures vs the injector pressures and those differentials but thought too deep.
thanks for the easy lesson, I will make the changes. ...
ahh ok, I will need to get my other computer with excel and sort that out and look at the file you sent.
You mention I should be able to spot the difference, what does a person look for? I had...
Here is what I have for data for the injectors. I have tried to do this as correct as I could.
again thanks,
Dave
they are 60 lb-hr Deatschwerk injectors. I have the info I will need to find again but they came with all the info I copied in according to what I understood. It is a swap vehicle my 68 C10 swapped...
Thanks I understand. I will go and collect data and work on the VE table. I have read and understand what I need to do and have some tables setup in my scanner to make these percentage changes. ...
Hi all, I have been using HP tuners for quite a while but not nearly as knowledgeable as many on here. This is in my 68 C10. As I have worked on this I seem to have made things worse. I found a...
OK gotcha. I've been fighting my shifter so I'll proceed with a different one or work on this linkage arm.
Thanks for clearing that up.
Dave
I believe you are correct it wasn't a factory option. I thought some of the aftermarket controllers allowed that and was just hopefull it might now be adaptable thru HPTUNERS
Thanks
Dave
Hi all, can HP Tuners help set up a 4l80e with the tap shift like the newer 6l80 and such? Since I understand they are all electronic I didn't know if this is possible. I am looking to swap...
You can possibly use your phone as a hot spot if you can't get close to wifi. It doesn't take much and once you do it you wont need to do it again for that vehicle.
Dave
Thanks for that reassurance. that made sense to me but there are so many tabs, fields and charts to change I just wanted to confirm.
Dave
Hi all, I was comparing my original tune to that of my attempt to tune the VVE table. I found under engine\airflow\speed density the VE Coefficients have changed after I changed my VVE table. This...
Thank you for that. I am using fuel trims for this part throttle tuning. It just seemed strange to have a difference in the two charts depending on how I filtered them. My charts look good and am...
Hi all. I've looked around the other gen 3 and 4 posts too plus my notes rom my gen 3 tuning and seem to remember about filtering the data. The how-to posts didn't give me a definite answer. I have...
Since he had referred to them if they didn't get reset if it would give him some false info. Just a thought
Dave
The gen 5 tuning is all new to me so this may be a silly question. Do you need to rest the ltft after the new tune is written? I didn't know how quickly they will repopulate.
I've been fortunate to keep my truck. I've had her over 30 years. I guess that kinda tells my age lol. I did the gen 3 swap about 13 years ago before it became so mainstream to do. So at first I...
Thank you IARLLC. I have read lots of your posts thank you for the great info. You and several others are great assets to this forum. I had looked as well and didn’t see any difference either....
I am working to understand the VVT timing retard in that "EGR" area. The retard is pretty steep as you all know in the low area, it appears that the 2014 and maybe 15 doesn't have as much of the...
Thank you, I will do some comparing. I am gonna expect they are the same but now I will know.
Dave
I am working on my 2017 Sierra Denali 6.2 and have found reference to compare some parts in my tune to that in a Yukon. I don't know what all years but maybe 16 -17? If you have a stock tune I...
No, I have not written any tune to my truck yet. I was still researching but that one seems easy enough to give it a try. I did put it in "manual" and gear 7 this keeps it from going into AFM and...
