Hello i bought the ALDL cable and downloaded the Datamaster program and recorded some data from my PCM (i am trying to figure out why the car hesitates and idles rought ALL the time) . If one of you would be so kind as to look at my recorded file and see what is happening (if anything). As far as i can tell it seems pretty normal, maybe an O2 prob. but i have one of those i haven't put on yet. If you do not want to look at my recorded file at least can you explain what portions of the data i should be looking at to help diagnose and fix this hesitation. TIA

 

I use datamater to log all my runs and Tunercat to tweek my BH tune. E-mail the file to hvyss@hotmail.com and I will revue the file and e-mail you back and tell you what I find if anything.

You might read this (thanks to Injuneer) for some background on what the data means.

 

You are definitely going about fixing your problem the RIGHT way!.. as opposed to saying "my car bucks and surges, somebody help!".

If you want you can email me that file. OR try and host it somewhere for everybody to read. Some vital members are kinda stubborn and would rather view the data as a .csv file which you can convert the .uni file to by clicking on File/Export engine data.

 

Why do you have such a problem with this? I don't need DataMaster.... I don't want DataMaster, I don't even use a stock PCM in my own car. I just want to help people. In return for my help, I simply ask people to offer me the favor of providing the file in a format I can use. Why does this bother you to the point where you feel obligated to comment on it?

I'm really at the point where I'm simply not going to even offer to help if its this big a problem.

 

I was only messing with you, Fred. I know you would have requested that format eventually so I was merely letting him know to have it available to look over. Most of the guys on here dont use it but I know your input is highly beneficial so dont take my comment as a personal stab at you.. more like a subtle nudge.
