At what point do you really need to data log?
I know that once you start to mod your car you open up risks. I'm not trying to go into 10's or be the fastest guy out there. I just want a car that has some pep and can hold its own. I didn't buy a MB 55 to turn it in to a full race car and having to log and baby sit everything.

When you're messing with your a/f ratio that's when you have to data log. Squeezing as much power out of your motor to achieve the best performance.

I like knowing what the car is doing stock to slightly modified to fully built. As such I think it is always better to have data, than to not have it...What you do with the data is another subject altogether .....

Yeah no real need to datalog then. Bout the only thing it might be helpful with is letting you know IAT's to see if your pump is working properly.

Go with a nice standard box tune and enjoy. They run safe air fuels and make nice hp! I will never forget going stock to Kleemann K2. It was amazing and super safe. What a blast!

The only thing I data log is IAT and timing for the most part. I look at the fuel trims somewhat but with the setup I have and running race gas I don't have to monitor much. The best thing to have if your modded is AFR gauge just for safety.

what kind of timing do these cars run.

Roverron

OK so I guessing to get AFR I'm going to weld in a bung in my headers. Or can I put that in my mid section?

Duc1098E500

Roverron you would need a wideband so get an accurate reading.

Roverron

yea the welding in a bung is for the wideband to read.

Get the wideband as close to the engine as you can. If you are only installing a single wideband I would place it on the drivers side as number 8 cylinder seems to run the leanest for most.

Just to let you know when I used to tune my turbo cars and the only time I connected my wideband was when tuning. Ortherwise, I remove it so I don't kill the sensor prematurely.
