Introduction/Rookie Tuner

Hello all,

I have a Jeep cj7 with a amc 258. Had a Howell TBI system on it. Did some engine mods: 4.0 head/cam. Now the stock tune does not run correctly. Picked up a autoprom from moates and downloaded tunerpro RT. Now that my account is up and running I will download the correct XDF for my ECM. I believe it is 1227747. Does anyone have a BIN file for me to start with? Will also take any tips/suggestions.

Thanks

you can copy your current chip from Howell a d maybe use that as a starting point. is your current setup fuel only or does ecm control timing as well?

Just fuel. Currently I have no plans to control timing. I will copy the stock tune and start data logging.
