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.

Nice work Karl!!

[@leoamaya1818]

Very nice work. I have a 1994 impala SS & she could certainly use a tune. Time is money & thank you for sharing 💯

[@EllweinEngines]

Thanks.

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

Awesome

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

[@DanielChristiansen]

btw- i would check the charcoal canister and solenoid as the rich condition conincided with a 100% DC on the CCP.

[@EllweinEngines]

@@DanielChristiansen Wow! I never thought of that. I need to go back and check all of those logs. By the way the knock circuit fix ended up being a new old PCM. In other words the PCM was at fault and not the knock sensor circuit. So much to condense into one little video.

[@EllweinEngines]

Thanks Daniel. DataCat? Going to check that out now.

[@DanielChristiansen]

@@EllweinEngines Yeah its free for 10 days so you can try it out. I really like the fuel mixture histogram makes it real easy to apply corrections to fueling.

Man I wish you could give me some tips on my build, I’m in need of some good advice and help all the way around…please!

[@bigdiezel748]

Hey where those video at mane

[@grizzlygamingGG]

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.

[@EllweinEngines]

I can give some tips and or advise. Are you doing the tuning?

[@grizzlygamingGG]

@@EllweinEngines yup I'll be doing everything.

[@robss96dcm]

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

[@EllweinEngines]

Gotcha. I am pretty sure I turned it off but I better double check.

[@EllweinEngines]

That was it!!! Cat over temp. Man I love KZbin and thank you Rob for suggesting that. Nothing wrong with Cat over Temp except when you don't need it. :)

[@robss96dcm]

Anytime Karl, your welcome

[@JZ-nn1kg]

Where are you located ?

[@EllweinEngines]

I'm down in Southern Maryland

[@reddyfreddy]

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

[@EllweinEngines]

1 Chevy horsepower is about 10 Mega watts. I'm close!!
