Ok I'm glad I'm not crazy then for running a bunch of different programs. I haven't been very happy using pcm logger so far I'm trying to find something a little more customizable and "finished", it...

Is anybody successfully datalogging a 12212156 OS/0411 ecm (or similar) using an obdx pro vt in TunerPro? I've tried several different adx files and even deleted and reinstalled TunerPro. Every time...

Title says it all just wondering if this will work, I'm reading mixed things. Some say it will be fine others say it will need the 96/97 valve body and solenoids which is no big deal just trying to...

Thanks this is where I have my tables set right now vs a stock BPLH bin:

My current settings

18384

Stock BPLH

18385

So I guess nobody has seen this issue before where the MAT is enabled but doesn't add the extra TPS AE at lower temps?

No sorry my AFR displayed on my AEM wideband that I am datalogging in Tunerpro.

What I meant by open loop or closed loop is that I was running open loop while doing the initial tuning and getting...

With the scanner hooked up are you seeing high integrator/BLM numbers over 128 when the issue happens? Also does the o2 voltage hit about 850-900mV under wide open throttle? Most common cause for...

Hey guys, just like every other fall/winter since my build was finished I'm having issues running too lean when ambient temp is below 50 degrees F or so. Engine is a 350 bored out to 357 with bored...

I will try to get a datalog posted, it may be a bit as I need the truck at the moment and it's completely undriveable in closed loop so I'll have to make a special drive on a back road where I can...

Back to tuning on my POS 95 Sierra after letting it sit for a while out of sheer frustration. It's a 355 running 9.5:1 compression with a stock lt4 cam. Has a factory 5.7 tbi unit bored out to 50mm...

Oh absolutely I understand the difference, I was trying not to confuse anybody that may be looking to this thread for help by going back and forth between IAT then talking about MAT flags and MAT...

Thanks for all the info everybody and I reall appreciate the ideas. I ran to the local pick n save near my work on lunch a couple days ago and grabbed a factory air cleaner and hose clamped a piece...

Well so far using Trimalyzer is great I absolutely love how it's set up. It has helped a bit with my lean decel at highway speeds but I still can't seem to get the MAT/IAT sensor to influence fuel...

Thanks! I have no doubt he will, go figure when I'm trying to download it for the first time just happens to be when the file is broken haha

Has anybody tried to download Trimalyzer lately? I've been trying to download it from the ecmhack site on several different computers and the download keeps failing, not sure if it's something on my...

Thanks for all the info guys, I'm going to get the Trimalyzer set up and start fresh on this sometime this weekend hopefully.

Well I had done my initial VE adjustments in open loop and thought I was pretty close minus the decel issue so I switched closed loop on to see if it would fix the decel issue but didn't make a...

Just the sections where I'm actually at idle, pretty much just the 30-40 kpa range at 600-800 rpm. I haven't used trimalyzer, is it something in tunerpro or something I need to download? How do I go...

Still battling this even with decel enleanment and DFCO completely disabled though I've sort of just been living with it by dumping a bunch of extra fuel in that area so it only has time to climb...

Ok cool I didn't order anything yet so I won't worry about it. I was looking into the proportional gains and I'm trying to make sure I'm looking at the right tables, are they "proportional flow gain...

My truck does have a factory 3 wire o2 but I'm going to do the 4 wire swap anyways, I like the idea for sure. I have dfco disabled when this happens but I'll make sure to disable decel enleanment...

Oh yeah for sure definitely don't want to try to pull 5+ amps through the signal ground haha I imagine that'd fry the driver in the ecm pretty quickly

That's a great idea and heck for the price I'll definitely give it a shot

Finally got the open loop idle to work by using one of the bin files from the thread tayto linked and doing the exact same thing I already tried with raising the temp qualifier... I guess somehow the...

It definitely idles a lot better in open loop. I've only actually driven it in open loop once and it ran ok but I was mostly just trying to see if it would help with lean surge on decel at highway...
