Ok guys, I have been using HP since it basically only did LS1 cars. Been using it on and off over the years as I did mods to my 99T/A. I've kept the software current as updates became available....

Ok guys, I have been using HP since it basically only did LS1 cars. Been using it on and off over the years as I did mods to my 99T/A. I've kept the software current as updates became available....
Okay I had a chance to enter the formula I previously listed. It seems to be working and tracking the FAST meter as long as I put the meter in Single Mode and not averaging the two wideband sensors....
Thanks for the quick response.
I have some information that I previously found and used before acquiring the Pro interface and may be what you were referring to.
FAST AFR meter range is :9.6 to...
With the older software version I was never able to get the user defined formulas to track and match the FAST AFR meter correctly. So I upgraded HPTuners and also upgraded my MPVI interface to the...
I also have high flow CATS, but I don't think they have the same requirements that stock CATS do. They seem more for show when they look during inspections. I turned my COTS off but where I live,...
When flashing the PCM, I ensure anything that doesn't need to be on is turned off. Doors are closed (no courtesy lights), no heater/air blower running and no radio. I don't want to have any stray...
Attached is an injector data calculator. Input your stated injector size and your operating fuel pressure. I've used this a couple of times and never had issues.
Remember that the stated injector...
I think the guys point (Sunny) that you seemed to miss was that factory tunes may not be that great right out of the box and if the tune is worked, you can get favorable results (based on real...
Took a quick look at your scan. LTFT are pulling a bunch of fuel. Even though the STFT don't look too bad when you look at the Average, take a look at the max (+) and min (-) readings. They are...
As far as your voltage issues, I saw the same thing with mine. Had the alternator checked at Autozone and Advance and both said charging system was OK. Then one day I noticed it wasn't getting above...
Yes I am using a MAF. But even with it being used now, I still had to set up my VE tables with it disabled and work the tune as a SD. Once VE was dialed in using a dual wideband, the MAF is...
Glad I could help. Could probably do the same thing on a dyno if there was one willing to take the time.
Looked at your VE tables. To me it just doesn't look right especially at the lower RPM and KPAs. I have a '99 LS1 with free air mods, Weiand LS6 intake, SLP ported/polished throttle body, 32lb...
The only time I have seen that is when I was slowing way down, in third or fourth gear (mines a 6-speed LS1) and started accelerating again. Really loaded the engine but with the torque it has...
Because when you set up your histograms, the setting you are talking about means you have to hit the cell that amount of times BEFORE it will record anything. So if you set it up for 50, it means...
When I adjusted my MAF curve using WB AFR error vs MAF freq I was able to get the actual AFR very close to commanded. However, once I enabled trims again, they were off. So I plotted LTFT vs MAF...
My home weather station said 92*. Too hot for my liking unless I'm by the seashore somewhere.
WS6Firebird is right about the stock tune. My 99 T/A WOT PE equated out to be 11.7.
Anyway, looking at the scan, ECT and IAT are high and might be a contributing factor????
Well my friend I too am collecting a pension after 35 years of service to my country and have been building my own computers since the 8086 processor days. I can also remember when tuning a car was...
It all depends on how knowledgable you are about cars and comfortable working on them. When I bought HPTuners a few years ago I started reading everything I could before starting. I realized it was...
Not knowing if you have dialed in your VE table and MAF (if you are using one) first before adjusting timing, I will assume you did.
Looking at the data in your scans shows knock at the higher...
I tried the Beta when it first came out. I had problems with the tune for my LS1 and got tired of trying to figure out if it was the software or the car. Too many variables to deal with while...
I just don't understand why the Beta and updates aren't made available on the HPtuner's website for registered users. If I can still download version 2.22, I should have access to the Beta files....
I agree with going back to a previous tune and starting over, even if it wasn't perfect. I've had to do this a few times when things didn't seem to add up. Though it's a PITA, carefully rework the VE...
What does your nitrous kit recommend? Some tell you to install an inline fuel boost pump to maintain fuel rail pressure, others tell you to upgrade the injectors, (especially if your tune puts them...
