as the title says.

 

I have done this, couldn't get on of the front pipes off then it started to snow so didn't do throttle bodies, then it took me about 20mins just to get the other one back on :headvswal

just took the car for a ride and no difference at all :cry:

timing is still at 25 :headvswal

did you reset ecu when you changed it

yes.

How are you testing the ignition timing? Using Datascan or a light strobe? The only accurate way of testing it is using a light strobe as Datascan will show what the ECU sees as ignition timing (which may not be the true timing as set by the CAS). The ECU uses the CMPS, MAF, Engine Temp. Sensor, TPS, Vechicle Speed Sensor, Ign. Switch, Knock Sensor, Neutral Switch, A/C Switch, and the Battery as the Input signals to control timing. Based on this input the ECU controls the trigger signal to the Power Transistor to advance or retard the Ignition Timing.

 

The ECU controls Ignition Timing to improve acceleration and performance, while at the same time controlling vehicle emissions.

 

How to test:

o Warm up engine.

o Air-Conditioning off.

o Neutral gear.

o no load.

 

⇒ Timing at idle: 15 BTDC

⇒ Timing at 2000 RPM: more then 25 BTDC
