OBD1 Tuning, 1995 Impala SS 383ci with big cam

OBD1 tuning used to be easy. Now all of my old laptops that run the tuning software are either dead or close to it. DataMaster quit offering their software for sale. TunerCat OBD 1 is still available to me since I have a CD with license and compatibility mode. Anyone have ideas on good data logging for OBD1 ?
I'm using the Innovate LM2 wide band O2 system. I've had this unit for years! Love it. It always works. If I were using the HPTuners or EFI Live for OBD2 cars then the LM2 outputs directly to them and records at a very high sample rate. Easy data logging. With this OBD1 software I cannot lot directly to the DataMaster and so I just record video of the live AFR reading.
In theory 13.0 to 1 would be the best power but I have never found that to be the case. At the drag strip my own LT1 cars like to be at 12.5 : 1 But every car is different.
I just bought a Dragy (like all the no-prep racers). It is dead nuts on accurate as far as mile per hour and if you don't spin tire it will be dead nuts on accurate for elapsed time too. It is a great tool for gauging performance. (I rely on 1/8 mile MPH).

Thanks for sharing. Good to see you tuning obd1 still for those who haven’t done the LT delete mod.

I'm going to be playing with DST for my 2 '96s (I like that "spirited" throttle)

Hi Karl, i use DataCat for OBD1 logging, it has a lot of nice features including WB02 logging via A/C pressure sens line.

Karl, If that part throttle rich condition is cyclical it could be cat over temp coming on.

Could you help me tune a 1994 c4 corvette? 383 with cam, hooker Headers no cats 3 inch straight pipes. I think i need larger injectors but dont know what size to buy.

Nice try my man, but even with all that technology, you still need 1.21 gigawatts to travel back in time!!
