Just wanted to follow up to correct what I thought were my final results. It turns out the problem the whole time was the base tune was set up way too rich from the start at idle (like 10-11 afr). ...

Isn't that offset table you posted for the L92 12609749 injectors? It was noted here that they were slightly different than the L96 12613412 injectors and I noticed that the voltage offset tables...

Thanks for clarifying some of that. That is why things get unclear very quickly trying to learn this stuff. If you look back at LSxpwrdZ's post of the text files, both injectors are labeled. Hard...

Guys, so RedXray posed the question on which data is correct from the 3 sets posted in this thread because they are all slightly different. I understand the differences that come with vacuum...

Just wanted to follow up with what I found. I have this working now. I bought an AEM UEGO wideband kit 30-4110. The first sensor that came with the kit was bad. Kept going lean. I called AEM and...

I had thought the same thing. I have Speed Engineering long tubes. Narrow bands are in the end of those. I then had 3" exhaust swelled to fit over the header and use 3" wide band clamps over the...

Thanks for the info. This is my second new AEM wideband so I was struggling to think that it was bad. As for the O2 sensors, I have about 6 of them, all new, that I have been swapping in and out of...

So just reaching for any options. I put the tune back into closed loop and ran it down the road to see if I could start getting the O2's to respond and see if the wideband changes from lean. I...

Fuel pressure shows that I am 63 psi at the rails. That is with a cheap Amazon 100 psi transducer so the calibration for it could be off just a touch. Anyone know if it is an issue running the 7603...

I run the same setup in my other swap without issue.

Did not know that. It is a walbro 255 in tank pump.

Thanks for the input. The idle reads rich from cold because I left the OLFA table alone. It runs out to lean on warmup. Wideband reads fine from cold all the way up to warmup (about 100 deg) and...

Would appreciate anyones help. This is my second LS swap. I am just trying to dial in the VE at idle so I can make sure this is ready to tune. Starts up rich when cold and will run to full lean...

WB sensor is installed driver side just back from the end of the long tube headers connection. Does the transient impact factor not change with an injector change when the intake stays the same?

Thanks for the feedback. To answer a few questions this is an older swap vehicle so Cats are gone, stock 03 truck intake, no EGR, no ETC, Flex fuel disabled for the time being. I was under the...

Okay guys, I took my file and put the idle air and a few other areas back to stock. Also corrected the injector offsets to be correct for a vacuum referenced fuel rail. Right now the file is set...

Gotcha. Mine is set to "Percent". By a 1 point change I was saying going from 65 to 66. Thanks.

Awesome, thanks for the input. I don't believe that I had messed with the Units or Decimal places at all. Did you see something that would flag that, or just more of a recommendation?

I do have a stock truck intake. Vacuum referenced return-style. I am guessing that I just need to take the 0kpa column and copy that across the table so each column is the same?

Thanks Hondaeater, I will hopefully be able to scan using the channels list here in the next day or two. I pulled the injector data from this forum converted to Gen3 already. Seemed like quite a...

Hey guys,
I have a 2003 6.0 P59 from an Express Van in a truck build. Changes are Sloppy Stage II, headers, and 12613412 injectors. Had intentions of doing E85 eventually. I have the 12587603...

I guess I am just asking why the differentiation? I would love to upgrade, but I have 1 vehicle that I tune as a hobby and already have a lot of money stuck into this tuning module. The upgrade...

Any reason that the saving of unlicensed files is only allowed with the MPVI2 and not the MPVI1? I am trying to help my dad tune his car. He has the MPVI2 and I have the 1. Kind of a bummer I...

I have a 2000 LS1 with a 228R and the 36lb GTP injectors. Mine runs fine with the settings attached. Yours seem to be different. Not sure if that is it or not.
