HELP needed, please read
I was hoping someone can help me figure out something about a low timing issue I have been having lately. My car has 27,000 miles with the mods in signature. The ecu does not advance timing more than 5 or 6 degrees, we have it set to advance it 12-15, this is from 6k-7.5k rpms. The car does not break up or misfire but I am still thinking that I need to change the plugs becasue I think they are causing my timing to be low. The car has 0 knock. What do you guys think, any input would be appreciated.

I don't have any timing maps or logs, I am tuned by 4ws, I am sure he will come on here and discuss this matter into further detail. We both think it is the spark plugs. He finally got the car to make like 8or 9 degrees. He has tried every trick he knows but it still does not want to run what he sets it to run. Would the spark plugs cause this even if the car isn't breaking up or anything?
What has the barometer been reading in Fl recently. Same here but 2 degrees less (I'm in SC).
The baro table has a direct influence on spark advance since it directly affects propagation and (decrease of) ignition lag

I have no clue, but I don't think it would make my timing go down 10 degrees, this has been going on for about 3 weeks now, maybe more but that's when we logged it to retune the car. My question to everyone is can the spark plug cause this?
maybe you were changing timing at the wrong load cells. Sometimes what you see in the datalog are not the same load cells in EcuFlash (MAF can be messed up). So posting the EcuFlash map files will help a lot. Don't tell me you can datalog the file but you cannot pull the map.

How do you flash the car? If you have a Tactrix cable you can log the car. people can't do much to help if there are no logs or any maps to look at. If you can provied these then maybe you'd get more answers.
