Hey, guys, I'm doing a cam and lifter swap and doing away with the DOD on a friend's truck. Would like to ship the ECU to a shop for tuning as it's far cheaper than buying a MPVI3 and doing it...
Yes, I had the older versions saved and the installer refuses to function because it's an older version. Piggyback systems will flourish due to this nonsense, but I understand their position and I'm...
So...I downloaded 4.4.4 and installed it, changing the C:\Program Files etc by adding the 4.4.4 to the end and it still overwrote the old version. I do, now, have the same torque convertor screens...
Please forgive my ignorance on this, but... If I install the latest file in this manner, will I then have another, second version of HP on my laptop to use for editing? While keeping my older version...
That's an interesting tactic. I looked at the tune and see no TM in Normal, only in Performance, and never on the 3-4 shift. I've always wanted to try locking the convertor in second and then...
It does stay locked during shifts, as it always has since I started tuning with HPTuners. I have a different trans in the truck that will go in another project vehicle soon, and the shift kit deletes...
I'm on Suite 4.0.12 and have been for (obviously) quite some time. I didn't think I could lose functions that I had before if I simply left it alone and continued to use it?? I believe I first...
That's right where I'd expect to find it, under trans, then convertor. Trans, then General only shows options for what trans is in the vehicle. 4L60, 4L80, standard, etc. The Torque convertor tab has...
It's been a couple years since I have looked for this, but could have sworn there was an option to check if you wanted the computer to always disengage the convertor to shift gears or not. My 2005...
Ok, well, it seems my understanding of how the MAF is used is incorrect. I had thought the MAF was not used above 4000 in the stock tune, and due to airflow increases, I should limit it's function to...
I'm doing a 2005 Silverado with a p59 and a pair of gt3582r turbos on a 6.0. Engine has rods and pistons, stage 2 LJMS cam, springs, studs, etc. I would like to consider keeping the stock MAF on the...
I found where someone else posted the transient fuel setting needing to be set at zero with larger injectors, so I changed that, and what a difference. Spent several hours re-logging my MAF and VE...
Hey, guys, I have a question regarding minimum pulse and commanded fuel/trims on this application. I have Fuel Injector Clinic injectors and have entered their data, no issues. The tune was quite...
I'm back to struggling with this tuning based on airmass situation, lol. I have been driving the vehicle and cautiously adding boost as I go. I am up to about 7 psi and have almost reached the end of...
Thank you for taking the time to offer intelligent replies; I appreciate it, greatly.
My preloaded spark table shows map vs. RPM and does fill up with actual, final spark data. That's right where...
The simplest way I can answer is this: I can't determine how much manifold pressure equates to XXX airmass number. Therefore, I don't know where on the map I'm at 5 lbs or 20. Does that make sense?
...
10_ss, thanks for the detailed response. I should clarify, I was not trying to see error in the scanner. I was only responding to jjs saying that he set it up to show error in the scanner.
My...
I'm not sure I follow that. if I set up a histogram to match the timing table, what error can I see if there's no "desired spark" as opposed to what shows up in the histogram as actual? Or would I...
I emailed HP and Bill responded that 90% of their software is this way. He also said that if I'm looking for some "free tuning advice" that I should come here and ask. That kind of shocked me as he...
Can I change from airmass to a map value in the spark tables? I can't convert the airmass values to input an intelligent amount of advance. Not sure how to approach this, or how you guys are doing...
That does the trick. I didn't realize that there are tables that trim the A/F ratio in open loop, but the description of the tables does explain this. Zero the table and it has no impact on the final...
OK, ill look into these maps. Just so that I'm clear... the computer will trim the fuel if any STFT table has numbers in it? It doesn't shut it off completely due to temperature? So we need to find...
81749To add some information.... I unplugged the o2's and fired it. Stays nice and consistent as the base VE table commands. Stayed too lean, and while it was running, I made another quick histogram....
I may have jumped the gun a little with my other thread. Upon watching the wideband on startup, I can see that the A/F starts out super lean (1.2) as I've removed much fuel from the VE table. But as...
In continuing to work with this and study the results, I do feel it is changing the tune. But as it runs from first startup to say, 30 or 45 seconds, it goes from quite lean (1.15) to slowly making...
