This tuning mode is the most popular Dyno tune method for normal aspirated racing engines that have poor vacuum signal or throttle bodies. It is easier because the Dyno locks the RPM’s to a specific load site and the tuner can move the load through the other axis. Then he […]
Matrix MAP Tuning
This tuning mode is the most popular Dyno tune method. It is easy because the Dyno locks the RPM’s to a specific load site and the tuner can move the load through the other axis. Then he tunes specific intervals. The ECU will then interpolate points in-between his tuning points […]
Graph MAP with TPS tuning
This tuning is the same as MAP graph tuning with the added adjustment to get the engine to idle on TPS calculations. It is still easy to tune without going to TPS matrix. So first tune according to this method. The same principles will apply to the timing graph but […]
Graph MAP tuning
Make sure all safety precautions are met as specified by the Dyno Safety rules from the manufacturer. Also remember to keep an eye on the water temperature of the engine. If at any time you hear detonation, back off the throttle immediately and lower the timing in that RPM range […]
Accelerator pump tuning
Accelerator pump selection The accelerator pump setting is used to richen the fuel mixture when accelerating to avoid flat spots or bog. Here you can select not to use it, use either the TPS or MAP or both signals. Below is the selections to setup each pump for TPS and […]
Fuel Economy Cut-off Tuning
This feature will cut fuel to the engine under low load conditions. This will save fuel in town and downhill driving. The engine will run against compression as you are decelerating. It will also prevent flaming in the exhaust during accelerator blip. The injectors will be cut when the MAP […]
Calibrate timing
This section discusses how to set the ECU timing to be accurate with Engine timing. This is important to see realistic timing values on the software and also settings that use the timing real-time bar to protect the engine. First get the engine to start and idle smoothly as discussed […]
Starting and engine for the first time
The ECU has a few sequences how to start the engine. An engine requires an initial prime pulse of fuel to start the moment the engine is cranked, then a richer mixture during cranking. Once it started, it also requires a certain amount of richer mixture than idling to get […]
Settings Before Tuning
When you get to this point your engine should start and idle easily and the basic settings in the startup procedure should be set. Start with a warm engine at working temperature. Remembering you have a start-up map loaded from a running vehicle. All the sensors such as TPS, MAP […]
Connecting the ECU for the First Time
Now you can proceed with the following steps. If any steps do not correlate with the ECU operation, stop and look for the faults. Ensure that the ECU is earthed!!! Notice that there may be steps not applicable to certain ECU’s. Then you may skip them. Remove all the fuses. […]
