4L80E budget stand alone trans control making use of 0411 GM system PCM.

ALTER 9/26/16 – These days I have over 400 miles for this stand alone transmission control. Also, I not too long ago turned on the torque converter clutch to stimulate in overdrive. Things are performing perfectly and transfer exactly like it should.

While the topic claims. It is for anyone people who happen to be starting MegaSquirt, carbohydrate or something like that other than a factory laptop for his or her applications. This publish is made for OPERATION OF THE 4L80E INDICATION. I (Dale Follett) can document steps to make it perform a 4L60e as well if theirs adequate focus in it.

We (Dale Follett) ended up being tired of having our LS engine/4L80e transmitting wired upwards for whole handbook valve looks and desired it to move by itself immediately like a factory unit. This could possibly be easily done-by trading across the complete motor pc and utilize on a factory elegance PCM, sadly my vehicle happens to be wired up with MegaSquirt 2 i like the functions. A Microsquirt and 4L80e generate is $450.00, but thats a bit much to swing just for automatic transmission control and I wanted a cheaper option. And this is what we created, simply expense 2 HP tuners Licencing credit and a PCM within the junkyard (full-blown of $125.00) as well as some of my own time.

0411 PCM which was a throttle system hard drive by wire create. Is irrelevant whether or not it am a 4L60E or 4L80E BUT creating a computer system that went the transmission from factory from your junkyard now is easier.

All your valuable standard wires garbage. Soldering irons, cable strippers, electrical record or you wish to be elaborate warmth contract, line, etc.

All of the relaying electrical fcn chat visitors connections, while the manufacturing plant PCM electrical connections, and a OBD2 diagnostics harbor connector the HP tuners program to PCM marketing and sales communications.

As already reported this really the 4L80E GM relaying USING UP-TO-DATE UNDERGO RELAYING CONNECTOR.

Truly the only needed PCM stimulant from the motor is merely RPM and throttle place. The rest of the PCM’s inputs originate the transmission itself.

Greatest factor listed here is PCM choice. You need a PCM that runs a 4L80E ultimately or 4L60E that also reviews the crankshaft placement controls. Instance, simple firebird organize is working a 4.8L LS gen 3 engine that has the 24X controls. So when it comes to PCM or tune document, they had to be considering a car which had the LS 24X crankshaft situation detector wheel and so the PCM’s RPM feedback would see truthfully. Whether your managing a older style 350 smallest block chevy you’d wanted a PCM out of a chevy express van and set-up the engine for the same crankshaft situation detector and wheel to get the appropriate RPM insight into the PCM.

The next thing is TPS. For us using EFI this is often no problem because we all curently have a TPS sensor. For those that are looking into carrying this out for your carburated setups, you need to fabricate a mount onto your carbs for a TPS sensor. This PCM NEEDS A TPS FEEDBACK being function correctly as a transmission management section.

Right now on exactly how to wire it in. Their unique are no pre-made wires utilize’ for doing this therefore you will need to develop your very own utilize. It is far from a lot of work though and absolutely nothing as opposed to creating a engine wires harness. I go by pinout number and connector pin counts complete our circuit harness’ since wiring colors may be dissimilar to model and make automobile the exchanging section around. Simply produces existence straightforward because cable colorings may change from X to by nevertheless the PCM’s hooks and connector pinouts refuse to change The PCM and wiring directions i personally use happen to be for any 0411 or P01 GM PCM with the orange and Red PCM fittings. The azure connector is known as C1 along with Red connector is called C2.
