Best datalogging option for OBD2 LT1 engines

[hexdmy]

I know that TTS Data Master and possibly EFI Live are good options for the OBD1 LT1 , but what are people using for OBD2 LT1's ? Curious to know if anyone has had success using EFI Live to log enhanced GM PIDs .

Some other tools that are advertised to work, but how well I'm not sure:

AutoTap

Palmer Engineering ScanXL

Ease Diagnostics

Auto Enginuity

If anyone can add to the list or comment on any of the above tools, it would be much appreciated .

EFILive product wise you would need the EFILive V4 OBDI/ALDL Scan Tool license. This is a software only product; we recommend this cable from Moates Ware.

I use EFI_Live V2 for the OBD2 LT1. I created maps to use with my data for speed density tuning. The serial wide band input is a plus. It does not have a PID for the MAF in hz. I do not know if that is an availble PID for that PCM.

This is a list of the supported PIDS that comes up.

Interesting. I didn't know V2 worked with the LT1

It only works for data logging! Sorry if I mislead anyone.

Interesting, I've seen v4 before on the EFILive web site, but cannot find it anymore, is it still available ?

Regarding v4, you mention it works with OBD1, I'm looking to use it with a OBD2 LT1, is this possible ?

I did not know that EFILive v2 tool supported datalogging for the LT1 , that is good news, and another reason why I should get setup with EFI live lol . Too bad MAF Hz is not included, although the pid list in the .xls attached in your post look pretty good to me .

Thanks for your input.

I created / modified v7 files for the LT1. Its been along while since I played with them cause I went the 24x 0411 route. I may have an updated version somewhere cause I saw some spelling errors. I recopied them and ran a spell check. Maybe someone could include it in an update. Let me know if you have a questions or if there are errors (I also remember fixing some scaling issues). Just replace the sae generic file and add the GM_LT1 file.

Enjoy

Beerman, thanks for posting

Bringing up a very old topic, and I'm a bit of a noob to EFILive, I tried using Beerman's "sae_generic.txt" and "GM_LT1.txt" files in the configuration folder, however I cannot get the scan tool to point to "GM_LT1.txt" for the enhanced parameters. I did copy and paste in the vehicle VIN number (see attached image), trying both with and without quotation marks.





So, am I doing something wrong, or possibly is there a compatibility issue with the latest version of EFI Live v7.5 scan ?

Thank you in advance to anyone who can offer some assistance !
