Testing the Circuit This is the circuit I’ve built. Tested on my car Connections as follows: Later on, I connected it to the 12V accessory line in the fuse box. This line functions only when you turn the car key on. Refer to your car manual in case you cannot identify the ignition coil, it may vary in shape from car to another. Be careful not to manipulate connections related to ignition coil especially when the engine is running.

I’m not sure I follow you when you say the “stem is to wide for intake”.

Best bit of “maximum information” to have is to not tune carbs incorrectly. OE specifications are readily available and the only spec worth using. Kent, thats precisely the point of monitoring and testing methods. But how do you tune the carbs – or anything else if they “break”, or fail leaks, for example? The same applies to every mechanism on the bike – heat, tire pressure, compression, vacuum, oxygen content, emissions, vibration, noise; virtually anything can be measured.
From reading this forum it’s clear that spline alignment is a significant concern. Instrumentation is available that could monitor spline “health” by either vibration or noise level.
VW Diesel Tachometer
However, before I begin, let me catch you up to date, especially important for those of you who aren’t quite up to speed. I’ve been one of the people asking this question, and it’s been long reported to me that the FIP trucks had a wiring harness with a ‘shunt’, which powered the ammeter. However, my findings today show differently. As Dirty Harry once said, “A man’s got to know his limitations” After I explained the basics on Ford’s setup, we set out to find out all we could.
How to Install a Tachometer. A tachometer is used to indicate the revolutions per minute (RPM) being performed by a car engine. Most cars with automatic transmissions are not equipped with a tachometer, since a tachometer is mostly used to.
Donation Info The turbo diesel hummers have electrically controlled fuel injection so it was easy to put a tach on this truck. All the sensors were already there for the computer. On the other hand installing a tach in a non-computerized older Hummer involves getting an electrical signal from the engine that varies with the rpm. Diesels, unlike gas engines do not use an electrical ignition system so you can’t pickup the engine rpm using ignition impulses.
Because of this you need to either install a pickup of some kind or grab a signal off of something else electrical like the alternator. The articles below are examples of what other owners have done. The pulses that this sender outputs were not strong enough to drive my non AMG tach.

How do I hook up my tachometer? Standard Ignition Coil If you have a standard ignition coil you can use the negative terminal of the coil for the signal source. If you have a high output capacitive energy discharge type coil it is recommended that you install a tachometer filter to prevent damage to the tachometer.

A good basic tool that gets the job done. The idle air flow is balanced first. The Uni-Syn is adjusted so that the ball rises about half way up the tube. By adjusting the idle speed screws the idle speed is maintained about RPM and the flow is adjusted so that the ball raises the same on both carbs. Once the idle air flow is balanced the service screw is used to raise the engine speed to RPM.
The Uni-Syn is adjusted so that the ball rises about half way up the tube at this higher speed. Using the dogbone on the or the balance screw on the the flow is balanced so that the ball raises the same amount on both carbs. When the high speed is balanced, back off the service screw and recheck the idle air balance. The two adjustments should be independent but sometimes it takes a little fiddling to get all the linkages set up properly.
The mixture adjustment is done with the large knobs on the bottom of the carbs.

Supercharged Ford Lightning Supercharged Harley Davidson We have received hundreds of phone call and e-mails asking us if we sold a boost bypass kit. We looked around to find out who was selling boost bypass kits and we were shocked at what we found. RPM Outlet will provide the instructions for installation at no charge. This allows you to realize all the benefits of these kits without spending money on what amounts to, paying for words.
This modification is for off-road use only.
One of the most common glitches on the BMW E30 3 Series is an erratic engine idle. Have you noticed that the idle seems to surge constantly? Does it constantly move between and RPM? Does the idle stay steady at RPM? In this tech article I will go over the steps involved with checking.
There are a large number of modified vehicles that no longer use an ECM engine control module to oversee the emissions and performance parameters of their vehicles. Because of this, the pre computer-controlled type HEI distributor is often used; it is a relatively cheap, stand-alone unit with good to very good performance potential, and has a good track record for durability and reliability.
A computer controlled HEI distributor work basically the same as a non-computer controlled HEI except for the lack of a mechanical or vacuum advance mechanism some early versions did use a vacuum advance ; the ECM determines the advance curve electronically. The only other change you can make in the advance curve is to manually advance the base timing usually worth a little HP by itself. This is not a bad thing, it leaves funds available for parts that WILL make the car faster!
If you have disconnected the 4-wire ECM connector going in the side of the distributor or the wiring between the ECM and the distributor is damaged there will, again, be no advance and the check engine light will come on. Yes, you can remove a computer controlled HEI and drop an old-style mechanical advance distributor in its place; it will physically bolt right in. But it will cause the ECM to throw a code the check engine light will be illuminated because the ECM senses if the computer-controlled portion of the distributor is functioning every time you start the engine.
To run the engine efficiently without the ECM, sensors, and related equipment fully functional, the distributor and carb need to be replaced at the least. It’s simple, easy to tune, and plenty powerful to light off any naturally aspirated engine up to RPM if properly equipped. But it does have its limitations and it has a few built-in design flaws- or “compromises”- like most any mass-produced part that has a limit on how much cost the manufacturer can justify. All carbureted GM engines in cars built from to about ’75 and trucks from back use this type HEI distributor.
RPM tacho questions
With a Vacuum Gauge One of the easiest and cheapest ways to check an engine for serious issues is to use a plain ole vacuum gauge. A vacuum gauge can tell you a lot about an engine’s condition, similar to a full leak down test – but in a much easier way. In just minutes you can know if an engine is healthy or not.
For those of you modifying your engine, I think it makes a lot of sense to make sure your engine is in top notch shape before spending money on modifications, especially if you’re working on a high mileage car.
An air–fuel ratio meter monitors the air–fuel ratio of an internal combustion called air–fuel ratio gauge, air–fuel meter, or air–fuel reads the voltage output of an oxygen sensor, sometimes also called AFR sensor or lambda sensor, whether it be from a narrow band or wide band oxygen sensor.. The original narrow-band oxygen sensors became factory installed.
Disconnect negative – battery cable first. Refer to applicable Service Manual procedure and remove seat. Refer to applicable Service Manual procedure and remove fuel tank. Stop the engine when refueling or servicing the fuel system. Do not smoke or allow open flame or sparks near gasoline. Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. Remove speedometer sensor cable from mounting clips under tank.
The 3-place speedometer sensor connector  is located on the frame beneath the seat. Remove connector from t-stud and disconnect. Cut cable tie holding sensor wires to right rear frame tube. Refer to applicable Service Manual procedure and remove headlamp, for work clearance. Remove speedometer, bracket, and harness. Disconnect the battery, negative cable first.
