Hondata

-(Serial # of K-Pro) I looked at the casing of the ECU and didn't see anything.
-(The Calibration) I do not own a laptop.
-(Datalog of a problem) I do not own a laptop.
-(Vehicle) 2002 Honda Civic SI.
-(ECU #) Stock ECU 3780-PNF-A03 Underneath that 2091-304481 Then in red ink it says 273 and there is a blue line and a red line with SM written on it aswell.
-(Modifications) Greddy Turbo Kit w/ Intercooler & BOV. Greddy intake and EVO2 Exhaust and of course K-PRO.
-(Problems) Well i don't get the cylinder missfire codes anymore. I've had my car retuned since last posting to you guys. I have these codes P0172 System Too Rich (Bank 1), P0600 Serial Communication Link Malfunction, P0011 Timing Over-Advance Camshaft Position Acuator.

My altenator went and when the mechanic replaced it, that serial communication code came up i believe and now the temp doesn't read and the brake light remains on the dash.

As for my main problem If I drive my vehicle normal and then say 10minutes later or even shorter I try to accelerate fast and it climbs RPMs but just as fast as a stock 02 Civic Si. Now while driving if I turn the car off and then turn it back on It will run fast again and the blow off is louder and longer and not short gasp. I can also turn the vehcile off from a stop position and the problem will go away aswell. This is pretty annoying problem as you can prob tell.

For the error codes you are getting you really need to follow the Helms manual (factory service manual) for those specific error codes. Since this all happened after a mechanic worked on the car, you should probably have it looked at again to see if he messed up some wiring or damaged anything. The reason it feels stronger after you erase the error codes is that the error codes are putting the ecu into limp mode. This is to help protect the engine from damage.

Alright I went to a shop. They checked out the vehicle and said that theres nothing mechanical that they can change to prevent the advanced timming. That it has to be done through hondata. They also reset the check engine light and when it was driven hard the light didnt come on. When I drove the car back home (soft) then back to the movies (soft) the check engine light came back on displaying that advanced timing code. What do you suggest I do now? They're telling me to go to a hondata tunner.

That would be a good place to start. But it does sound like whoever worked on your car has messed something up...It may even be a blown fuse somewhere.
