MWR's AEM EMS4 kit is the most powerful tuning tool available for your 1ZZ or 2ZZ powered Toyota and the price for this plug n play kit is unbeatable.

This kit fits:

2000+ non-US market Corolla models equipped with 1ZZ-FE, 2ZZ-GE, 3ZZ-FE and 4ZZ-FE engine and 3-row ECU connectors (see diagram.) This includes Runx, Sportivo, TS and Compressor models.

Main Features:

Full tuning control of fuel, ignition timing, idle speed, VVT, VVL.

Additional outputs configurable to control boost level, radiator fan, fuel pump, nitrous, shift light, water/meth injection, etc.

Adjustable rev limiter and launch limiter.

High resolution datalogging capability with or without laptop connected.

Closed loop fuel control using stock O2 sensor or aftermarket wideband O2 sensor (sold separately and strongly recommended.)

Fully configurable knock sensing and control.

Very flexible- easily tune for larger injectors, bigger cams, stroker, high compression, ITBs, supercharger, turbo, nitrous... you name it!

MAF meter may be removed (optional- you just need to add an air temp sensor) so no more limitations caused by maxing out the MAF at high boost levels. You can also make your air inlet and intercooler pipes any size you prefer.

MWR base tune provided- we'll provide the best start-up map for your application at no charge. This is a good base map only so an experienced tuner is needed to get the system 100% dialed in for your car.

Stock ECU remains in place to control stock functionality like coolant temp gauge and air conditioning. Also allows you to reconnect stock ECU quickly for diagnostic (OBD) or emissions legality purposes. The EMS (like all aftermarket ECUs) is not emissions legal and should not be used on public roads where emissions equipment is required.

Works great for 2ZZ swaps, no additional 2ZZ ECU or adapter harness is required. Just add MWR VVL connector kit.

Installation takes only minutes- no soldering or custom wiring required for standard install. Full install and tuning instructions are provided.

Included in the kit:

Custom configured AEM EMS4 engine computer

MWR custom plug n play wiring harness

OEM quality 3-bar MAP sensor (made in Germany)

3 meter USB programming cord

Programming software is downloaded directly from AEM HERE at no charge
