The Blaze MAP-4  manifold pressure and RPM

The MAP-4 is a 3 1/8” - 80 mm sunlight readable Manifold pressure indicator which can simultaneously display RPM and temperature from a universal RPM and temperature input.

The manifold pressure display is also available in the form of a scaleable analogue bar graph if the RPM input is not displayed.

The MAP-3 has a Hobbs meter (can be set to the current engine time) which is password protected, an engine running timer/flight timer and a programmable maintenance timer to schedule routine engine maintenance.

The MAP-3 features a programmable low/high alarm for manifold pressure, RPM and temperature, a handy magneto check function to easy diagnose magneto problems.

The MAP-3 records the maximum manifold pressure, RPM and temperature reached in permanent memory.

The MAP-3 can also be interfaced via the CAN bus to an external RDAC unit (Remote Data Acquisition Computer). This allows for easier installation as the RDAC unit is normally mounted in the engine compartment. The RDAC can supply engine data to multiple MGL instruments.

We ship worldwide. At checkout you can choose from low cost airmail options and express courier services like DHL or FedEx.

Within the UK we normally dispatch using Royal Mail or DHL. You choose the level of service at checkout.

VAT sales tax (20%) is included in the price displayed on the website. This tax applies to UK customers and EU customers. It will continue to apply to customers in the 27 EU member states from 1 January 2021. This is because we are located in Northern Ireland. The Northern Ireland Protocol, agreed by the EU to facilitate cross border trade with the Irish Republic after Brexit, also applies to the rest of the EU.  We continue to charge the UK rate of vat to customers in the 27 EU member states and there is no further tax to pay upon delivery. We can continue to zero rate the vat for EU business customers who enter their vat number at checkout. 

Customers outside the EU do not pay vat and the tax will be removed at checkout. Local import taxes may apply - check with your local authority.

Currency. All products are priced in Pound Sterling (GBP, £). Using the "Currency" tab you can change the displayed currency to either Euro (EUR, €) or US Dollar (USD, $). This is an indicative exchange rate, automatically updated daily and is based upon the prevailing bank rate. The price you see may be displayed in USD or EUR but payment processing will be conducted in GBP. This means that your card issuer will apply their usual exchange rate, which is likely to be different from our indicative rate.
