I did read on here that the Sniper does "funky" things when tapped into. If it's just a. Can someone please explain why I can't tap into that wire? I see TCI sells one, as well as other companies. Sorry if this has been covered a million times, but I really couldn't find the answers as to why I can't split that signal.

Thanks in advance. Join Date Dec Posts I have a Compushift unit for my SBC. The TPS signal wire for the Sniper was not designed to be shared. I've talked with Holley reps on this during my install and the issue as best as I understand it is the ECU is dependent on a clean signal from the TPS and any variance would have disastrous effects.

Altering the wiring in that manner would also void the warranty. I was able to reuse the TPS sensor that came with the Compushift unit and get everything to talk correctly with each other. There's nothing stopping someone from sharing the signal, but Holley would offer zero support if thus created an issue or damaged the Sniper unit.

Thanks for the advice! Join Date Feb Posts It's been over 10 years since I carried out electronic theory formally, so I'm a little rusty. Ignoring the increased chances of adding RFI into the TPS signal, the circuits impedance would change when splicing another controller into a shared signal. Input circuitry tends to have a pull up or pull down resistor sometimes both to reference the input so it doesn't float.

Usually tuned externally on a circuit board, but could also be provided within the IC performing the analog to digital conversion. Placing two or more controllers in parallel will change the expected resistance value. Then other differences between each controllers 5 volt signal reference they won't be exactly the same0V reference, the controllers reference to the vehicles 0V, ground loops between the controllers, RFI, etc.

The 0V signal reference could also be coupled to the vehicles ground differently between the products. DC coupled on one and AC coupled on the other, or not coupled at all. The ADC will be presented with different 0V references shifting the calculated value of the input. Don't splice into signal wiring. Electrically there are ways to share signals, but this adds complexity to the design, additional failure points, and cost.

Use a dedicated TPS to maintain segregation between the controllers like the one you have selected. Edelbrock F 2V dual plane intake manifold.

Quick update on the TPS problem, and more problems...

AOD Transmission. Ford 9" 3. Pacemaker PH 2v Tri-Y extractors to 2.But if you like to drive your car more than a quarter mile at a time, at some point you have to think about drivability. With fuel prices skyrocketing, newer technology is appealing to the smaller group of hot rodders who used to shy away from it. We borrowed a car from Ryan Daniels, of Riverside, Ca. Ryan got his car as a project from his brother about ten years ago when he was only When it came time for his brother to sell the car, Ryan told his parents he wanted it, and staying true to his word he got the car running and has been driving since.

Ryan installed a 4L80E in the Camaro to take advantage of modern transmissions, and installed a manual valve body. They also have a kit for their 4L80E-based 6X Six-Speed transmission, which is capable of handling up to horsepower. Gone are the days of tweaking your old transmission with different stall speeds and low gear sets to get the performance or economy you want from it.

Technical Details

For those who have something other than what the General built, TCI sells adapters for many Ford and Mopar small and big block engines, including the modular Fords. The Camaro currently has a manual valve body, losing the luxury of automatic shifts.

We replaced it with a standard valve body to regain full use of the automatic transmission and to control the way it shifts, including manual shifting - with the EZ-TCU you have a choice. Our installation began with removing the manual valve body that was installed on this Camaro.

Once the valve body was replaced, the rest can be as detailed as you want it to be, routing wires away from obvious sources of heat and keeping the harness almost hidden if you desire. You always want to be sure that you tie up the harness to keep it from resting against hot or moving parts, while at the same time allowing for the flexing of your vehicle so as not to pull on the harness during hard runs.

All the plugs are in place, making the installation a breeze. When installing, make sure all wires are kept away from excessive heat. The LED indicator on the face of the unit should always face outward. Most all of your connections will plug directly into your transmission and control unit, and regardless of what type of distributor or ignition box you have, there are detailed instructions that will get you connected properly.

The Control Unit should be mounted away from EMI and places where water can get to it, with the face of it easily accessible. You will also need to keep in mind that you'll have to connect the handheld for monitoring the TCU while driving. Solution for Cable-Driven Speedometers. If you are still running a cable-driven speedometer, TCI has you covered.JavaScript seems to be disabled in your browser.

I have silverado with engine and 4l60e. I purchased exact same kit for mine. It will be more than enough to run this engine. I purchased this unit to go with my 4l80e and I must say that it is very easy to use and install It should work just fine as long as it gets a proper signal from TPS and speed sensor. I just finished installing one on a silverado.Page of 22 Go.

It can be mounted in the engine. It is good practice to mount the TCU with the. This way, there is less chance of moisture getting into the TCU if it. In particular. Optional, longer communications cables are available if needed. It will flash if the on. To take advantage of this feature, the TCU will need to be mounted so that.

The handheld will also indicate if any faults have been. Please read this instruction sheet carefully before beginning installation, and also take a moment to review the included limited warranty information. Page 2 This connects to the round connector on the passenger side of a 4L60E transmission.

Page 3 TCU and a fuel injection system, for example if needed. Yellow Bump Up Use momentary switch to ground to request an upshift. Page 6 But the TCU will be damaged and system performance will degrade. It sends a calibrated speed signal to the SCU. Installation Sequence This is a general outline of the installation process. Read all of the component specific installation notes for more detail before beginning the installation. Page 8 Its first task is to take you through the Setup Wizard.

It also serves as a scan tool by displaying live data and diagnostics information. Beyond basic setup, you can also adjust other settings to suit your preferences. Page 9 In addition to live data readings, the Live Data screens also feature several Status Indicators.

They show when certain conditions are met. These indicators can serve as a troubleshooting tool by offering a way to verify that the various switched inputs are wired and functioning properly.

BAT V Battery voltage. The Setup Wizard takes care of calibrating this sensor. It can easily be verified using this display. YES will let you continue the Setup Wizard.For many people who are used to the limited wiring harness and the hands-on approach to working on their car, the idea of having an electronically controlled transmission might seem like a stretch.

But some things are a lot easier than you might think. If you can hook up a few wires, route them in the car and down to the transmission, then you can do this installation — piece of cake!

This article will show the setup and advance features, assuming the installation has been completed. We had installed a 4L60E overdrive transmission and needed a better way to control how our transmission operates. After the initial wiring and ECM installation, it was simply a matter of turning the ignition on and plugging the included handheld into the ECM and a volt cigarette lighter source.

The Setup Wizard walks you through some basic questions about your vehicle, making it an EZ process. As we showed in our installation articlethe Setup Wizard walks you through a New Tune, which will erase any existing tune, but will not erase the default settings.

The initial selections are the engine, transmission type, the tire diameter — which can be selected by the tire size, the PPM Pulses Per Mileand the rear axle ratio. The tire size and gearing are important to set up the speedometer seen in the Live Data selection, and are completely independent from the speedometer output wire used during installation.

There are three setup screens in the setup wizard that allow you to fine tune your transmission for firmer shifts, or even torque converter lock up speed. Vance suggested running through the setup wizard with the values at the default settings, and driving the car before you make any adjustments.

If you want a softer shift at low speeds, adjust the value lower. For a firmer shift at higher speeds, adjust the value higher. The three Live Data screens will show you real-time readings from your vehicle, including speed calculated on tire size and gear ratio.

It will also indicate what gear you're in, as well as whether the converter has gone into lockup. To fine tune the settings, you can enter advanced settings and change how your transmission performs under light and heavy throttle individually. If you prefer a smoother transition through the gears at low throttle, you can adjust the shift points and firmness to a lower setting. Then for a firmer, more positive shift at higher rpms you can increase the setting.

These are all broken out in a simple display that makes it easier to understand. As seen in the video above, there are a couple of other settings that can be made to the EZ-TCU with added wires that allow you to change the characteristics of the transmission. This includes locking up the torque converter full time with the gray TCC wire, and a purple wire for Performance. Both can be activated when connected through a switch to a solid ground location.

But Vance warns that these are not for those who lack experience and should only be used by people who are more familiar with how the transmission and torque converter lockup function. The gray wire will force the converter into lockup full time, but it must be switched off when lower speeds are reached, and definitely when the vehicle comes to a stop. Leaving it switched on would make the transmission more of a direct drive, and and can cause lugging and shudder when coming to a stop.

The purple wire is for performance and should be used with caution as well. The orange speedometer input wire, as discussed in the prior article, is for aftermarket electronic speedometers and when used can be set up through the handheld by selecting the PPM Pulse Per Mile that coordinates with the sender in the transmission.For many people who are used to the limited wiring harness and the hands-on approach to working on their car, the idea of having an electronically controlled transmission might seem like a stretch.
