I'm trying to remember, I thought I had saw a thread that said HP Tuners could scan (not write) a 96-97 LT1 vehicle. I was hoping somebody could confirm, I'm about to expand into them and need to make sure I have the scanning solution lined out.
Thanks!
The scanner connects and scans just fine.
It was a long time I tried and don't remember how many parameters you can scan, or if you can log useful PID's and make histograms for tuning purposes.
I'm going to have a LT1 in my hands in a few days, I'll post results.
I successfully scanned a 96 OBD2 LT1 with HPTuners last week. You won't be overly excited with the number of fields available though.
Thanks! I understand it will be limited, but if I can log MAF and WB at the same time, I'm good to go!
MAF Hz isn't supported, at least in a 97 Vortec Pickup I scanned yesterday :(
I really really miss a good scanner for 96-97 LT1, MAF tunning would be a lot easier
here is what I have used
The 96-96 LT1 Pcm works good
but the scanning is very limited without a Snappy or Tech2
on the other hand 94-95 PCM swap with OBD1 Datamaster will show you all the major players
BTW SEMA 05'
Steve Cole and his engineer form TTS had a demo on display of the Datamaster OBD2 for LT1s,
I called several times after SEMA 05
they said it was not ready :pray:
Just being able to scan MAF at all was a big help! Unfortunately, no histograms means it wasn't nearly as efficient, but I made it work! However, not fond of it and I don't think I'll be doing any more 96-97 unless someone REALLY wants it done ($$$).Quote:

pop in the first cal and I'm 90% done. :yay:
beside most the big dawgs get switched to 94-95 computers and use TTS Datamaster to log
What about O2 sensor data?
Do you knbow if the scanner displays it?
Thanks
How hard is that switch?Quote:

Yes it does.Quote:

Any tunign you do using O2 data needs to be done 100% by hand
No MAF Hz
No AFR Error (because no AFR Commanded PID)
No histograms
That's why
Could i do this on a 96 corvette?
what are you guys using to tune the 94-97 cars with? Tunercat? or something else?
Yes, I use Tunercat for the 1996-1997 LT1/4 cars and scan with Hp Tuners.

Here's a reply i got from Tunercat a while back when i asked if i could tune a '96 car for a buddy with their software....where are you guys buying your TC stuff from for 96-97 cars? i'm not looking to spend an arm and a leg to maybe tune 3 cars and put this stuff on the shelf.

Thank you for your e-mail.
No, our LT1 tuning kits do not support the 1996 - 97 OBDII LT1 cars, only the 1994 - 95 OBDI cars. The OBDII cars require a completely different setup. To tune the OBDII cars you'll need our OBDII Tuner program. The OBDII Tuner program comes complete with powerful tuning software, an OBDII interface converter and all the cables necessary to connect your PC to the vehicle. While we continue to do the development work on the OBDII Tuner program we don't sell this program directly. The OBDII Tuner program it is currently available from three sources.
1. A low-cost version is available through JET Performance Products (www.jetchip.com) as the JET Dynamic Spectrum Tuner. This package comes complete with four licenses to tune four different vehicles. Additional licenses can then be purchased for additional vehicles.
2. The real-time version of the OBDII Tuner program which allows you to do real-time tuning (while the engine is running) is available from Craig Moates (www.moates.net) when you purchase their Roadrunner emulator (which is needed for real-time tuning).
3. A professional version of the OBDII Tuner program which allows you to tune an unlimited number of any of the vehicles currently supported by the OBDII Tuner program is available from Wester's Garage (http://westers_garage.eidnet.org)
Best regards,
TC
tunercats sold out the rights to tunercats obd2 tuner to jet tuner, so those of us that had tunercats obd2 can and still get obd2 updates from tunercat but no new sales from them,, but i think you can still get it if you go through moates and buy there ls1 roadrunner kit, then you can get the obd2 cable from tunercats but it will cost more than what the rest of us paid years ago for tc obd2 tunerQuote:

Did you look into the 411 PCM swap then the car can be tuned with hp tuners and u can junk the opti spark and just go dis did the swap on my 95 lt1 and love it
Just an FYI - to make it work right, you do need to add a resistor to the knock sensor input pins on the PCM or you will get Knock Sensor error codes... Or you could change the knock sensors but that's allot of work and messy. Without the resistors knock still works but you get an error code, you could disable the code... or do it right. Just pull the 95 ECU cover off, add the resistors across the knock sensor inputs. That's it!Quote:

I have done it both ways to several cars and all of them worked the same.
At first I installed the resistor to the PCM, but I stopped doing that because I found that just turning the code off gives the same results. The knock sensors work good in both cases
