Did I mention the pump cost me $30 at the pick and pull and included the connectors and shock mounts? When I told the guy it was for a project, he cut me a deal.

I just swapped the regulator in my alternator from 4 pin to 2 pin, so now it's like a 2006 or newer alternator.

I PWM it directly from my DIY transmission/car controller. I can command the alternator not to do any work till a few seconds after the car started and then slowly ramp up the voltage to normal levels. I may also measure the battery voltage before the engine starts and increase the charge for a while if it was low.

I started a thread in Hybrids section, on how to use the 2 wire 2006 and later alternator without a ECM/BCM. 2 pin 2006 + alternator. Don't throw it away!!

I pulled the pump out a a S40. But my buddy who works for Volvo said the pumps from all the models that use them work the same. There may be one that has a variation on the reservoir, with a remote extension.

Bought a "Maxi" fuse holder and 80 amp fuse for the power steering pump.
The white fuse is the 80 amp maxi, blue ones are standard mini and micro fuses just for size.

I'm impressed by the 8 GA wire on the fuseholder.

Burried in my Cougar build thread is my experience with those. Never again.

Andrew, Thanks for the heads up. I'll go and check it out.

Over the past 2 years, I've completely redesigned the DIY 4L80E controller and body module.

The first version was based on an Arduino Due processor board and LCD display. The reason I used the Due was because it was blazing fast. But it had some down sides as well. These down sides included inconsistent power up, 3.3v instead of 5 volt operation and no built in NVRAM (can't store settings when powered off). I worked around these and got it to work, but I wasn't happy with it and the display sucked.

The new (final) version is based on the Arduino Mega board. As it turns out, the Mega is more than plenty fast enough for the task. It's a 5 volt board, so no jumping through hoops to interface it. It can store and retrieve settings after being powered off. Has lots of I/O pins to connect to the rest of the world.

Here is some of the basic functionality:
It controls the 4l80E
PWMs all the fans: 2 radiator, 2 intercooler, trans cooler and oil cooler
PWMs the two fuel pumps
PWMs the alternator
Connects to the AEM infinity with CANBUS
Controls Boost
Controls the BOV
Displays alarms from AEM or itself.
Triggers the AEM two step
Controls the backup lights
Controls the brake lights
Scramble button
Fuel level sensor
Paddle shifting input
Line pressure input
4L80E temperature input
7" touch screen display and control center


I don't plan on having any gauges in the Vette. The touch screen has more than I need to use this car as both a cruiser and strip car.

This is the heart of the controller

As a former Neon owner (2 97 ACR coupes, and a 98 R/T coupe) and occasional Arduino hobbyist, you have my attention. lol

This is the display/control with the 6.0 running. This is not the final enclosure, just something I 3D printed.



The Vette can be operated in a bunch of different modes. Each mode has it's own shift logic, shift points, boost in each gear and display screens.

This is cruise mode. Automatic upshifting and downshifting is based on load and MPH or optional paddle shift. Cruise mode and be switched to sport mode which is like cruise mode, but with higher shift points and more boost per gear.

Thanks... Did you notice that my Neon was a 2.2 liter? 425 at the wheels at 21PSI through a loose automatic. I ran at 34PSI.

Ryan, not worried... they'll get a headache trying to figure it all out.

Here's burnout mode.


Each mode has many nuances and rules. For example burnout mode can be locked out if the shifter is not in 3. shifting is triggered by RPM only. It only shifts from first to second and has it's own set of boost levels for each gear. When the MPH comes back down at the end of the burnout, it automatically changes to drag mode.

Yeah, I saw that. I seem to remember someone building a Shadow/Sundance with a 2.4L bottom end and 2.5L head some time ago.
I dug a lot of the Chrysler turbo stuff back in the day. I always thought it would be fun to take an AWD, woodgrain sided Chrysler Minivan and add a 2.2 Turbo/5 speed combo and go **** off Mustangs.
A friend of mine back then had a pretty fast 97 ACR Coupe that became a race only car. Ever heard of Matt Tripp?
