I have researched this topic but could not find any info to help me. The Problem/question i have is, why does the truck start in open loop, then fuel system status goes to "non stoich" then finally...
[QUOTE=GHuggins;759581]You have to download from hpt's website. Won't show with the normal update. That was the mistake I made too.
I did pull it from the website..
I opened up the tune file...
I just downloaded Beta 5.1.1971, wiped vehicle in HPtuners file, re-polled for supported parameters, then did a read entire. I still don't have the Pedal table...
What am i doing wrong not to...
First off want to Thank Ghuggins for the writeup he did on installing the SCIAP sensor to a L83 truck, also to Alvin that makes a great harness for the SCIAP. This was my first time ever re-pining a...
Thanks for the ongoing tuning help, I will try to create a model based off of your suggestions.
So had to do a log after I zeroed out cam retard and adjusted the VT to what the scanner was saying. I believe the cam Zeroed out made that torque dip go away, and the higher VT kept the tranny...
They only added the SCIAP linear and offset. Would be sweet if they did the other two. I will still need to get ahold of Will for those.
I believe you have already altered the background tables you speak of when you had me do a write entire, on another thread.
I did bump up the VT tables to match, you can see 2nd gear was...
Question on cam timing. I have a BTR V2 stage 1 truck cam. I setup my retard from the website. In the attached log I'm making what is saying good power, then suddenly drops actual and commanded...
FYI,
I contacted support about tables 4013 and 4014. They just added them to the latest Beta download.
I did notice my MAF was off quite a bit around idle. Thats corrected now and I brought the center portion of the DD table up slightly, kind of took some of the bow out of it. Also tweaked my SOI...
The stumble i had originally posted about is all but gone. I attached a mixed driving log. normal driving, holding gears to fill out STFT table, WOT from cruise on highway. Doing that is the first...
This is great!! I haven't had time to do a log yet, but I believe you are correct with bumping up the DD a bit. Throttle feels a spongy around the 50% area, but it doesn't surge either. Will be...
Yes there is one wire going from a sensor in the manifold to the MAF. After looking back at the install manual, the harness i have is to bypass MAF temp sensor and use the one they sent for the...
Ok so I did some work dialing in my VVE since most responses say to do that. My original tune was MAF only. The tune in this post is what I have now. Still wants to stumble for a second when...
I have had this truck for a while and did most of my tuning a few years ago, with help from others. for the most part it runs great, but sometimes if am coming to a stop the wideband goes to 1.20...
Sent you a PM
on the tune file magnuson sent me with tvs 1900 kit for a 2018 sierra 5.3 with a 3 bar MAP it had MAP sensor linear 312.50 kpa and MAP sensor offset -11.25 kpa
