ECM Tuning
I usually hang out in the 67-72 page and the 73-87. Just wondering if anyone here has tuned an OBD2 ECM with their computers, editing maps and such. Kinda new to the whole thing and am pretty tech savvy so not afraid of anything. Just wondering if anyone has used TOAD before and what tips people have out there. Just thought it would be a pretty cool thing to try. Thanks!

Re: ECM Tuning
TOAD is just an editor, so you'd still need to run a tuning program to actually extract and flash the data.
We do vehicles with HP Tuners primarily, but EFI Live is another option thats common. Whats your goal? |

Re: ECM Tuning
HP Tuners and EFI Live do pretty much the same thing. They have cables that connect to your OBD port and then to your Laptop.
They can read the contents of your ECM, "copy" those tables and settings (aka the tune file), and then use their respective programs to make changes. Then, those changes are saved, and "flashed" back into the ECM. Entry level cost is around $499, cost varies a bit between them and any licensing or credit costs afterword. Be aware, while its great for people to learn and make changes, its very possible to blow sh!t up, or make changes that cause plenty of headaches. |

Re: ECM Tuning
Running my late model GM stuff with EFI Live and it works great. You have the capability to set fuel trims, Speedometer/tire adjustments, Fuel cutoff points, fan turn on times, and also adjust transmission shift points, all from a laptop.

Re: ECM Tuning
Not really sure what TOAD is but for a beginner I'd recommend checking out the free version of tunerpro. If your tech savvy it will give you an idea of the nuts and bolt behind the bigger fancier tuners. Craig Moates' support site also has lots of good info and also check out gearhead-efi and one of my personal favorites pcmhacking.
