Hi! I want to buy a power programmer,i see they are many types.Which type you suggest to buy?Thanks

 

For what year? I have a Hypertech for a 1999, I'll sale for $150.00.

 

Please answer the following questions:

-What year C5

-What MODs do you have,

-Automatic or MN6?

-What are you expecting to get out of the results of the hand held tuner???

Hand held tuners are NOT going to get you BREATH taking HP/TQ increases.

If you have an AUTOMATIC Transmission, they will do a good job of making the shift a little firmer and some other trans performance mods.

If it were me, I would do all the bolt on mods that I could afford and then have the PCM professionally tuned.

Hi year 2002,mod air filter,mn6.I know that the hand held tune is not good,but i want it most to have access to the engine to see what problems have the car when the check light open.I know a way from the dash buttons fuel,option who you can see the codes.But i want it some thing better if is possible with the programmers,for example i can delete that the car need service etc...

 

I do not understand what you want to do. What exact messages are you seeing??

If the car needs servicing; service it.

If you getting a service engine soon message, you need to figure out what is triggering the message.

Getting a $400 programmer to delete a message is just plain crazy. Read and post the DTCs. That will allow us to point you in the correct direction to fix your specific issue.

You do NOT have any modifications that would require any PCM tuning or tuning to eliminate monitoring functions that would cause PCM codes.

The hand held programmer is NOT going to allow you to delete PCM monitored parameters. You can purchase EFI Live or HP Tuners For $800. and that will allow you access to ALL the PCM programmable features.

The service i do it from my own,i have not do any modifications,expect for the transmission who was auto and i change it to manual.I thought that the power programmer allow to all pcm parameters for that reason i want it.This codes in the dash i have
C2115 H C
C2110 H C
C2100 H C
C1214 H C
Also the traction control isn't working and start when i change the transmission from auto to manual.Thanks

 

The 1214 DTC is an internal problem inside the EBTCM. You can send it out to one of the people who repair them OR you can open it up and attempt to do the repair your self. It requires cleaning up poor solder joints and replacing the power relay.

DTC C2100, C2105, C2110, C2115, C2120, or C2121
Circuit Description
The tire pressure monitor (TPM) system has 4 radio frequency (RF) transmitting pressure sensors in each wheel/tire assembly. As vehicle speed increases above 32 km/h (20 mph) the sensors internal roll switch closes which puts the sensor into drive mode. In this mode the sensors begin to transmit once every 60 seconds to the remote control door lock receiver (RCDLR). The data within this RF transmission is translated by the RCDLR into sensor presence, sensor mode, and tire pressure. The RCDLR waits for the first sensor to go into drive mode then checks if all sensors have gone into drive mode.

Conditions for Running the DTC
Vehicle speed is above 32 km/h (20 mph) for 35 minutes

Conditions for Setting the DTC
Any given sensor does not go into drive mode, or does not transmit at all for 15 minutes.

Action Taken When the DTC Sets
A DTC is stored in memory
The DIC displays the SERVICE TPM SYSTEM message.
The DIC displays the suspect tire pressure as dashes.
Conditions for Clearing the DTC
A current DTC will clear when the malfunction is no longer present.
A history DTC will clear after 100 consecutive malfunction free ignition cycles.
Use a scan tool.
Diagnostic Aids
A newly replaced RCDLR will set DTC C2121 upon the first ignition ON cycle. If this DTC is set, refer to Tire Pressure Sensor Learn .
Loss of, or low system battery voltage will cause all of the sensor Id codes to be erased from the RCDLRs memory and set DTC C2120. If this DTC is set, or this condition is suspected, refer to Tire Pressure Sensor Learn .
If the vehicle is stationary for more than 15 minutes after being driven the sensors will go into stationary mode. Always test drive the vehicle above 32 km/h (20 mph) to ensure the sensors are in drive mode before viewing tire pressures on the DIC.
If there is an open in the serial data circuit to the receiver, the DIC will display dashes for all tire pressures and the SERVICE TPM SYSTEM message.
Occasionally sensor transmission will not be received by the RCDLR due to vehicle level RF interference.
Test Description
The numbers below refer to the step numbers on the diagnostic table.

Tests if the malfunction is system, or vehicle condition related.

Tests if the sensors internal roll switch is functioning properly.

Tests if the malfunction was corrected by sensor replacement, or if the malfunction still exists in the RCDLR.

Schematic Reference: Tire Pressure Monitoring System Schematics

1
Did you perform the TPM Diagnostic System Check?
Go to Step 2
Go to Diagnostic System Check - Tire Pressure Monitoring

2
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, select the remote function actuation (RFA) system diagnostic trouble codes (DTC) function.
Does the scan tool indicate that DTC C2100, C2105, C2110, C2115, or C2120 is current?
Go to Step 3
Go to Diagnostic Aids

3
Since some occurrences of this DTC are caused by certain vehicle conditions, review the TPM system with the customer to verify the conditions under which the DTC set.

Did vehicle conditions cause the DTC to set?
Go to Diagnostic Aids
Go to Step 4

4
learn the tire pressure sensors. Refer to Tire Pressure Sensor Learn .

Did a horn chirp sound when learning the suspect sensor?
Go to Step 5
Go to Step 6

5
Use the scan tool in order to clear the DTCs.
Operate the vehicle within the condition for running the DTC.
Does the DTC reset?
Go to Step 6
System OK

6
Replace the suspect tire pressure sensor. Refer to Tire Pressure Sensor Replacement .

Did a horn chirp sound when learning the suspect sensor?
Go to Step 8
Go to Step 7

7
Replace the RCDLR. Refer to Remote Control Door Lock Receiver Replacement in Keyless Entry.

Did you complete the replacement?
Go to Step 8
--

8
Use the scan tool in order to clear the DTCs.
Operate the vehicle within the conditions for running the DTC.
Does the DTC reset?
Go to Step 2
System OK

Check and reprogram the Tire Pressure monitors and see if you can clear the DTCs after that.

not to mention for cheaper than a programmer you can send your PCM to ECS for a flash tune and get better performance

 

I will check step by step to find the problem,many thanks for everyhting!!!
