Inertia dynamometer design guide, DIY-
Guide to constructing your own dynamometer. The inertia principle can be used for engine or chassis dynos of all sizes and with DTecs 'DYNertia' package it's never been easier. Make sure you also check out the DYNertia DIY dyno system product page for further information.
Brake dynamometer design tools, DIY-
Tools to assist in designing your own brake (absorber) dynamometer. The brake principle can be used for engine or chassis dynos and with DTecs 'DYNertia' package it's never been more cost effective. Make sure you also check out the DYNertia DIY closed loop dyno system product page for further information.
Temperature Sensor Calibration Tool-
With just 3 measurement points, create a characteristic curve for any resistive (NTC) temperature sensor as commonly used in automotive applications. Also reveals voltage output and sensitivity of these sensors when used in practical applications.
Airflow bench design, DIY-
Cheap, easy and accurate. Perfect workshop companion for our 'Dynertia' DIY dyno software & system. Flow your own cylinder heads, inlet systems, exhausts etc. take the guess work out of those modifications.
Testing fuel mixtures (Lambda) after a converter-
Do you need to test fuel mixtures before the catalytic converter when using a 'broadband' air fuel ratio meter? what are the disadvantages of conveniently testing at the tailpipe.
Air density and tuning, the use of RAD-
Relative Air Density (RAD) is vital for tuning. Understand the concept the experts use to tune their engines for maximum performance under all atmospheric conditions.
Design an accurate fuel mixture probe ('Tailpipe' Lambda)-
Get accurate readings at low gas flows with your 'broadband' air fuel ratio meter and increase the life of your expensive sensors.
Ignition coil dwell time and mapping-
Practical guide to understanding ignition coil dwell time, determining the figures to program and why it's so critical to get it right.
Ignition coil energy testing, DIY approach-
Technique for measuring the stored energy of an inductive ignition coil. Important information to help select the best coil for your performance application.
Multi spark ignition systems, Inductive-
Understanding inductive based multi spark ignition systems. Why do it and is it right for your application.
High energy ignition upgrade-
Upgrade your old vehicle to a High Energy Ignition (HEI) system for minimal outlay. If you're seeking the performance benefits or even just replacing an existing faulty module, learn from others and avoid the pitfalls that catch so many.
Fuel injector data & flow rate converter-
