Do i need a compute to the rpm up in a 2002 mitsubishi galant

the computer is preset for rpm at idle it sets the timing -fuel ratio-etc to raise the rpm for what ever reason you would need to reprogram the computer --the transmission-and all sensors are effected also ---none of the programs including racing mess with the idle so you would have to make your own engine management program to raise your idle

While starting vehicle ETC warning display vehicle not throttle

This is a warning that something needs to be checked. This happens a lot when a vehicle is jumped with a dead battery. You may have to take to dealer and have ETC reprogramed.
Throttle Control Warning Light More and more vehicles are doing away with the mechanical throttle cable between the driver's foot and the engine throttle body, replacing it with a "drive-by-wire" system. In this system, a throttle pedal sensor sends data to an electronic throttle control computer, which evaluates and relays the throttle request to a specialized electronic throttle motor on the engine throttle body.
The throttle motor opens or closes the actual throttle blade, which increases or decreases the power output of the engine. The throttle control warning light illuminates when a problem is detected in the electronic throttle system.

A few options are possible here, as a few sensors can be defective on the new engine and cause this (crank position sensor, cam position sensor, mass air flow, etc.). That said, having worked for dodge before, on newer models (since around 2005 or so), when you change the transmission, the ECU usually needs to be reprogrammed with the correct serial numbers to match, or else it won't start or go in limp mode, so this could also be your problem. Best bet would be to ask a friend with a code reader or a mechanic you know that doesn't charge too much to pull out the check engine codes and see if anything turns up that list a sensor that could cause your problem. If there are no codes, call up your local dodge dealer and ask them if your particular model might need to be reprogrammed since the engine was changed. If so, schedule a repair with them so they can do it, as so far it can only be done with the DRB3 module from dodge and haven't seen much jobber boxes that can do this job. Hope this helps :)

Reprogram computer in car

If you want to ECU reprogramming, you should use a OBD2 tool - JALTEST MULTI Diag, it has many functions.


After selecting the car manufacturer, then you can make the diagnosis for the different menus on offer (depending on cars models):

1. Maintenance
Diagnosis codes from all computers
Reset maintenance interval
Modification of the sewage
Read / erase fault calculators
Maintenance of the particulate filter

2. Air Conditioning
Diagnosis of cooling electronic
Reading settings cooling circuit,
Test servo actuators

3. Pollution control
Diagnosis of the particulate filter
Electronic control of pollutant emissions
Control of the Lambda probe

4. Liaison to the ground
Electronic configuration of the size of tires,
Electronic configuration of tires (winter / summer),
Setting valves tire pressure
Diagnosis and management of shock-driven
Calibration of the sensor angle Driving (initialization of the steering angle)

5. Body
Implementation of safety airbags (lock / unlock)
Reconfiguration of a new calculator Airbag,
Diagnosis of calculators Airbag,
Rain sensor windshield (reading and erasing fault)
Test panel and activators of lights,
Setting Xenon headlights,
Rear radar

6. Post-Equipment
Setting up the radio,
Configuration loader CD,
Setting alarms
Configuration of the coupler,
Configuration bicycle loading system

7. Braking
Diagnosis of calculators ABS, ESP.
Diagnosis and unlock electric brakes.
Flush the brake system.

8. Motor
Diagnosis of any calculator injection engine (diesel, gasoline, flexfuel, etc. ..)
Programming of injectors
Electronic configuration of the EGR valve

9. Expert Mode
Diagnosis of advanced computers,
Configuration of comfort functions,
Change the language of the instrument panel,
physical measures (option with a probe - not supplied)
Direct access to all functions of diagnosis.

I have a p1135 code does that mean it the o2 sensor cause i have change the mass air sensor

Code P1135 is a vehicle specific code for selected Toyota vehicles - it really helps to know what car you are working on...Year, Make, Model, Engine Size, Automatic or Manual Transmission, etc. There may be Technical Service Bulletins that apply to your vehicle that cover things like reprogramming the engine controller to correct this code, etc. Nobody can give you that information if they don't know what kind of vehicle we are talking about.

In general, the code description for code P1135 is "Air Fuel Ratio Sensor Circuit (California Emissions )"
The possible causes are
1. Open or shorted Air Fuel Ratio Sensor (AF) circuit
2. Faulty AF sensor
3 AF sensor heater or heater circuit shorted or open
4. Engine Control Module (ECM) Fault

The Mass Airflow Sensor (MAF) cannot cause this code - this is a "CIRCUIT" code, not a not a "LEAN" or "RICH" Oxygen Sensor (or AF Sensor) code. The MAF can only cause lean or rich codes.

Most of the time, this code is caused by the sensor itself, however, as I mentioned earlier, there are Technical Service Bulletins for several Toyotas that involve reprogramming of the Engine Computer.

Took to ford motor co.said i had a speed

I don't know what they said exactly but there is no reprogramming requires when replacing any of the 3 things stated above. But if there is a notice and the technition finds that your car needs to be flashed or the ECM needs to have some updates installed. Well that is very different.

Cruise control installation

Not really sure on parts pricing (probably very expensive) but very complicated and work intensive to install... Need to get the engine computer reprogrammed for cruise control, install all the wiring (to the brake light switch, the speed sensors, etc...) install the servo/vacuum motor and cables to the throttle assembly...
