So, what is the best way to make sure your vehicle is as hassle free as possible, while you still reap the benefits of using LPG?

We did an installation for a customer running dual fuel (petrol and LPG), plus he wanted to run two boost levels. He wanted two switches on the dash to achieve these actions. One to switch between the two fuels, and the other to switch between high boost and low boost.
We sourced two switches that looked very similar to the original switches in the vehicle. Which by itself would have probably been good enough for the customer. But..

Most standard ignition systems are of the inductive type. These ignition systems can generally handle up to 15PSI of boost pressure, sometimes a little more, sometimes a little less. Gapping plugs down is not the best answer by any stretch of the imagination. Reduced plug gap can lead to a rough idle and increased fuel consumption.

What can dirty injectors do to your engine?
Cause Idle Problems – misfires at idle, lumpy idle, inconsistent idle speed.

What is the most important thing you think about when modifying your car? Is it power? Is it that you enjoy cruising around on a nice day? Is it that you want to win in your racing class? Whatever it is, it won’t be nearly as good (as much fun) as it could be if [...]

..what I want you to think about is – “What are the future uses of my vehicle, and do I have the correct parts on my vehicle to allow me to get to that point as easily as possible?”

A lot of high powered turbo cars have too much power in the lower gears. This can actually make the car slower than if it had less power, as the driver needs to spend more time reducing engine power (with his right foot), than getting on with the job of driving.

We all know that increasing fuel pressure means you get more fuel per squirt right?
Well that may be true, to a point.

Most of us know that you cannot begin to even try to start an engine without a timing light (although many have tried in the past – including myself in my early days). But, without knowing that your ECU is delivering the ignition timing that you think it is delivering, at best you can guess what the real ignition timing is, and at worst you can potentially cause damage to your engine.

This posts subject line is “General Fault Finding Mindset”, and that may sound a little dry to some of you, but what I’m trying to get across is that when you are installing and EFI system (or any automotive electronics for that matter), there are a few simple things you can do to speed up the diagnosis when there appears to be a problem.
