Hey Guys!!!!
Great news She's running great, idle good, data streaming with 7.4 memcal in G1 still have CEL I believe I ran a datalog can I post it somewhere to have someone look at it and decipher it for me?
It's about time! :laugh:
When you click the reply, look at bottom of box for Go Advanced. Then at bottom of that you will see attachment manager and can attach the TunerPro .xdl file you recorded.
Thanks EagleMark I uploaded 2 files 1 at idle mostly the onter with some rpms I know I need a knock sensor and will get it tonight 1 question the v6 has 2 knock sensorsI believe in series the 7.4 only uses 1 this should function ok right? ( the harness has 2 knock sensor plugs on it.
Thanks Bobby
Well, I road tested her today and it does shift, but when you get on it, the transmission flares and the engine goes way beyond redline, pegs the tach needle any other ideas out there?
Could this be due to the 4L80E memcal?
There's nothing in the Memcal that effects transmission except the chip/bin file!
Or an issue with the trans? Did you say it's new? Does not mean it's correct...
Is it flaring during the 1-2 shift or is it slipping while driving. I could not keep a 700r4/4L60E together behind a mild 350, much less a 454. Just personal experience here. At the minimum I would make for sure it has an 093 servo in it and check the line pressure with the transmission connector unplugged. I like 230-240 psi of line pressure with the case connector unplugged at 2,000 rpm.
As long as you are running a $0D based .bin and its not in LHM its not the memcal causing your issue.
You are probably needing to remap the line pressure tables much more aggressively than stock. Also you may end up needing to start the shift at a lower rpm than a stock 350. Might also have to reduce the timing in the cell closest to the RPM you shift at at WOT to kill some torque. What I mean by that is if you are shifting at say 4,400 rpm, you would make you 4,800+ RPM timing cells substantially lower than your 4,000 rpm cell to cause the timing to retard right as the rpm hits the shift point. I have alot of experience trying to bandaid a 4L60E in a high torque, heavy vehicle application.
Helllo There!
Guess what the flare was? The rear tires breaking loose! I can't keep traction when I get on it! This thing is a beast I'm going to have to get grippier tires!
Hi Fast355 thanks for the reply!
This had a 4.3Lv6 not a 350 v8 in it

I think you're right about the shift points I need to change them how would I go about doing that?
Hello everyone!
A quick update on the 454ss4x4 project. I've been driving it for a few days now and it's doing really well brought to a trans shop to double check after he took it out for a test drive the guy said "Man this truck is sweet" The one thing I came upon while browsing sites was the year of the bin files might matter the bin I used was for a 1994 4l60e but I have a 1995 will that make a difference?
