send them off and get professionally cleaned &flowed. i too have found used oem better than aftermarket.

Ah OK. Thanks Kur4o, I don't need to persue that avenue then. Another question then. OL SD Tune still. Have you got any info on Intake Temp...

Attached are my notes for the '0411 / 4L60E pinout.

Maybe this gearhead-efi thread might have some useful insights? Gearhead-efi member Fast335 indicates he's used the 0411 for standalone E-Trans with...

The more I know the more I don't know. If you go to transmission there is this a item name "pulse per mile" that sets your actual speedometer...

1project2many, Thanks for the input At cold engine start, growling is very weak and gets noticeable, after getting a good warm-up and heat soak,...

This table is only used with MAF, it smooth down the rapid transition of maf reading, so you got more flat curve instead of steep peaks. Usage is...

Here's the log I have so far. (If I did it right)

I thought that was strange. the computer is the 16196395 $OE mask. Here's some screenshots of the lists.

well most engine have seperate coolant temp and IAT...what mask/ecm/whatever are you running if you have IAT based tables and no IAT sensor things...

I found the Log file. Thanks for the help. I have started to log data! Pretty cool in itself. Now how to understand what I'm looking at. The main...

nice! so if you post a log and your current ve table ill make a tutorial for you

Just checked, I do have a closed loop flag.

Ok hopefully I can figure it out wasn’t there a site out there where I can plug in my gear ratio overall wheel diameter and transmission type and get...

if you have a closed loop flag in your log so we can tell if you're in closed loop or not then leave it on

I do have a wideband.

If you don't have a wideband you will need closed loop activated in order to get feedback from the factory narrowband O2 sensors so that they may...

I’ll grab a log file while I’m there at the shop. Do I disable closed loop or allow it to enter into closed loop? That’s one of the things that...

the parameters you HAVE to log for VE tuning: - MAP and RPM - fuel trim or wideband afr (or both) the parameters you SHOULD log, if available,...

Steveo, Finally, put in simple terms- now that part is clear. So, do we have to keep the system in open loop to do the base tuning and then return...

I am following with great interest. 4 inch stroked 6 L with the 603 computer and 4L60E. I've got it pretty close but trying to set up data logging so...

when you change gearing there are all these vss based transmission tables that need to be corrected. you need to do some math and find the...

by the way this might not sound easy but it gets super easy with practice, and then you can tune anything. tuning MAF is exactly the same as VE but...

what is a ve table? a table that represents how much air flows at a certain rpm and manifold pressure. so at 50 KPA and 5000 rpm it flows x air...

So back to the transmission it’s not shifting right sometimes it will shift to 2nd or 3rd but everything is off I know my gear ratio that the tune...

Hello, Welcome to the forum. 68 El Camino is one of the cars on my bucket list. I love the stance and I think they look great tubbed. Turbo...

The maximum pressure depends on the application. If they are "regular" TBI injectors that typically operate at 9-13 psi they can usually be used at...
