I am a newbie and I'm trying to tune for my new torque converter. I have a mail order tune that I've slightly modified over the years as my basis to go off of. The vehicle is a 04 Silverado SS with a...

I am in need of the injector data also.
Bump

I get what your saying with the alcohol content. Is it worth it to find out what the content is due to the fact that I use several fuel suppliers?
I will do some logs with the wideband next week...

Thanks for the help Joe. I have made the changes other than the B3601. What should the AFR be at? Shouldn't it be commanding 14.68 with any alcohol content? The truck isn't a flex fuel truck. It is a...

Hey guys I have a mail order tune and being that i'm a novice at tuning i'd like you to take a look at my log and tune files. I have a 04 Silverado SS with the 6.0L. Mods include a tr224 cam, long...

Hey guys.
I just got a new converter that i'm going to put in when the weather breaks. The converter is a Yank TT2600. I have been searching all over trying to find out how to tune for the new...

This helps out a ton. I need to change my idle and was trying to get all the information on it before I started.
Thanks for the great write up.

Thanks for the equations Joe. This is going to be a PITA on my truck. The bad thing is that I don't want to keep the mechanical gauge on the truck after I take the readings and that means that I will...

I looked at putting it there, but it has a oil cooler block from the factory that has hard lines coming from it to the radiator.
I also heard that there was an Allen head bolt on the front drivers...

So to do that I would need to do a voltage test while a mechanical gauge is hooked up to it, and get the corresponding data. So if at 2.5v I had 40psi and at 4.5v I have 65 we could make the pid that...

I have known about the factory gauge readings not being that accurate, so I did buy a mechanical gauge. Problem is that the only place I can install it is where the oil pressure sending unit is, and...

Hey guys.
I installed a cam, timing chain, pushrods, springs, and ported oil pump a month ago along with some other goodies.
I originally installed the wrong o-ring which the supplier told me was...

Hey guys what are the PID's that I would want or should log after my cam swap. I had the PCM tuned by Wait4Me performance and want to make sure everything is ok. I have a LC-1 but it's not configured...

Here is my modified stock tune from copy/pasting from the other tune to the stock tune and OS.
Also my truck has the 4L65E trans and the other Silverados with the 4.8 and the 5.3 had the 4L60E. The...

Here is the *.tun files for both the stock 12585950 (04072901) OS, and the W4M 12587603 (04073003) OS. A majority of the differences were in the trans tables.
My truck is an 04 Silverado SS with...

Hey guys I went to flash my stock PCM with my current tune from Wait4Me performance, and come to find out I have two different OS. The stock OS is 12585950 and the W4M PCM is running 12587603. The...

Sorry I haven't got to this reply sooner. I am not sure what or how my fuel rail pressure is measured. I know it is a returnless system though. I don't have the tools to measure my FRP so I will have...

I asked him if I could have him e-mail me the tune and he said that his software was different than mine and that he couldn't do it like that. He said that he helped do the software for EFI Live. It...

How does it know one PCM from the other? My W4M PCM had the the crank relearn done and the vin info and everything is the same for my stock PCM.

Hey guys I have a quick question.
I have a mail order tune from Wait 4 Me Performance from when I first got my truck. They sent me a new PCM so I took my old stock one and set it aside and had the...

Hi guys. I put some injectors in my 04 Silverado SS with the 6.0L from a 04 Sierra 8.1L. I copied and pasted all the injector info from the stock 04 Sierra tune into my tune. I heard they flow at...

Here is the user manual on the controller joecar.

Hey guys I posted a question on a FJO wideband install on a 04 Silverado on the GEN III topics section. I don't know if this thread section would be better to get answers from though. If hopefully...

Hey guys I just got an older FJO KWB0230 wideband. I also have the V-1 Scan and Tune Commercial. Can I cut the serial wires from the controller on the wideband and hook them up to the orange...

Joecar. I honestly am just starting out on tuning, and that file is my first tune I have ever done. As for the trans tuning, I know even less on that than I know about the engine tuning. In the...
