i have come to the conclusion that i need to data log my 86 TPI car . at this moment i know nothing , EXCEPT that a data log could help me diagnose a cold weather problem im having . my question is ,,, which is better "tunerpro " or something else ? . and whats all this "some 7165 ECMS wont allow a data log ?? . how can i have reasonable sucess ? any and all reccomendations or tips are welcome

 

I use TurnerPro Rt. I have recently got into tuning. The 7165 ecm can be a problem connecting when datalogging. It's a crap shoot, some will datalog all day and others will only datalog for a few minutes. I can datalog for about 15 minutes before getting errors. The 7165, maf, ecm's can be problematic when datalogging. Not sure why. I've been thru about 3 ecm's with varying results when datalogging. I researched and made recommended changes to the settings to include a timeout during the data stream and that seems to help. The members on this forum are very knowledgeable and should be able to get you on the right track.


The hardware (cable that connects the ALDL link to the laptop USB port), I got from Moates.

 

If you can find on a '259 is plug n play interchange with '165 it also has 2 instead of 1 inj drivers.

 

I need to learn how to datalog so I can figure out mycars w tpi. I have 3 so there's always something going on.

 

I data logged with TTS Datamaster. Since its free, I thought it would be a pretty common program to use. It seems simple enough to use, but when I posted the file and asked some questions about the results, I got next to no replies. I'm not sure why.
So, Is TunerPro RT the one eveyone uses?

 

tunerpro rt is what I use, setting up the programs for datalogging is a pain in the ***, my 165 ecm will only datalog with the resistor on the cable in place which causes issues.

 

I have my resistor set all the time for data logging also. I didn't know it could cause issues though? If it's not set I have a high idle. What issues can it cause?

 

So some months later, what did you use?
Have any results, comments or suggestions?

 

no , unfortunately , i hit a oak tree with my beloved camaro . to repair it would involve replacing the entire front sub structure. so , i have found another 86 IROC . its also a real "B4Z" car. that has 70,000 miles and is a one owner car . parked in 1990 due to the original owner dying. trying to score it as we speak

 

Bring that thing home.

 

im trying , unfortunately the person selling it has a delusion that its worth $5,000. and it dosent run , due to it being parked in dry storage for 26 years
