MoTeC Global Forum

Hi,
Today, in the process of starting the engine and doing the initial setup for the first time, we ran into some issues;
ECU Is MoTeC M130 with GP Lite Firmware and a Adapter wiring loom to the oem Mitsubishi Evolution VII ECU Connector

First of all, TPS input reads in the MAP, I mean when we open and close the gas pedal TPS stays zero and the MAP column changes, I saw that the MAP Input is using “Analog Voltage Input 2" instead of the TPS and I can’t allocate/relocate it in ECU I/O in the Software.
Also, I’d like to use an external Barometric Pressure Sensor and keep the Original MAP Sensor in the Intake Manifold, can I wire the Baro sensor to the External Provided “MAP” Connector that came in the Adapter loom ?

Second, Tachometer doesn’t work and also I can’t assign it in the software to "Half Bridge Output 2" like provided in the pinout-wiring document.

Third, Only the Radiator Engine Cooling Fan works and not both Fans (AC Fan).

Fourth, the Idle Stepper Motor doesn’t seem to work and the engine stalls, also I can’t find “Half Bridge Outputs 3-6” under ECU I/O, instead “Bridge Output 1&2” are assigned.

Fifth, I’d like to run the engine on dual fuel, Regular Pump Gas and E85;
How can I use a switch to run each fuel with a specific Engine Efficiency Table, Ignition Timing Table and Different Boost Targets for each fuel ?

Thanks for your input and help
Kam

Hi,

Which adaptor loom are you using? MoTeC does not make an adaptor loom for this vehicle/Package.

1, The easiest resolution for this is to swap the input pins in the M130 connector so that MAP sensor runs into A15 and the TPS is into A14. I'm not sure where the External MAP sensor is wired to in your loom so I cannot confirm if it will work. There are unallocated AV inputs that can be used for extra sensor, but the M1 will only use the sensor allocated to AV2 for MAP sensing.

2, Half Bridge 2 is allocated to the Idle Control system, you need to use a different HB output to drive the Tachometer output. Depending on the Tacho input requirements, you may also need to provide a pullup voltage to the signal to get it to work.

3, There is only a single cooling fan output in GP Lite, both fans will need to be wired to the relay that is controlled by this output.

4, Bridge output 1 is a output that combines Half Bridge 1 and Half Bridge 2 into a single control function that can drive a motor in two directions by changing the polarity of the two half bridges. HB3 and HB4 combined make Bridge Output 2.

5, GP Lite does not have support for Flex Fuel operation, not does it have support for dual fuel and ignition maps.

Which dealer sold the Package to you?

Hi,
Thanks for the clarification
Kit is bought from J-SPEC Performance Switzerland including the M130 ECU and Mits Evo 6 Wiring Loom Adapter..
So, if upgrading the firmware, can we resolve the problems above and have more control ?
And especially have dual fuel capability because the car is daily driven on pump fuel and sees track days on E85

Thank You
Kam

Hi,

Going to GPA or GPR will suit your requirements more.

Can you please explain the pricing difference between the two and how to upgrade ?
Thinking about GPR

Hello,
Swapped the TPS & MAP Pins and they worked like they should
Still have to add a Barometric Pressure Sensor so I can tune the vehicle at different altitudes and take advantage of the 3D VE Tables
Car has a AEM Lambda/AFR gauge installed, can I wire it to the M130 on the GP Lite Firmware so I can read Lambda values in the datalogs ?

Thanks

GP Lite (and all MoTeC developed firmware packages) only support lambda input from a MoTeC LTC

Hi,

What sort of altitude changes are you expecting to make? The VE system will compensate for changes in barometric pressure whilst driving, we have vehicles running the M1 ECU competing at the Pikes Peak Hill Climb that do not have specific Barometric Pressure sensors in place and the fuelling is remaining correct for the whole run. The MAP sensor will also sample the barometric pressure on start up and use this value as the Barometric pressure until the ECU is next restarted.

Changes of 1800m altitude are common to take place in less than an hour of driving from sea level to the village-mountains
