There are a ton of reasonably priced options for an LS1 harness. It makes ZERO sense to start converting your LS1 24 tooth crank to 58 tooth just to use these harnesses. LS1s use cable throttle bodies, knock sensors are in the lifter valley on LS1s, lots of issues.

It doesnt make sense to put an ls1 in a mustang to a lot of people either.

My motor didnt come with a harness or a throttle body or a computer. The other options I am looking at, I have to buy a computer, a harness and then pay more money to get them worked on.

This is great news for those looking for a factory style harness for the new LS2/3/7 motors...
So the computer can be reprogrammed to work, but is the program that is in it initially tunable? Most dyno shops don't have a tech 2 and the software to start loading in new VIN #'s.

No, they were not able to tune the ecm at first. 20 minutes later, yes. It was thought before that this ecm would be locked and useless for tuning.

I never thought the ECM was locked, I know it is an E67 unit which can be flashed to another program. The question, now answered, was whether or not the file that comes in the ECM from the factory could be tuned or not.

Glad to hear they got you all tuned up.

Runs awsome. I have just a bit over 1K miles now with no major problems. Took it to the local 1/8 mile again after tuning and changing the rear gears to 3:73's and ran some 7.80's @95mph on regular street tires....

This seems like it could be viable option pending one detail. Is it possible to to use the system on an LS7 that has a standard throttle body (eliminated throttle by wire)?

Most likely not.
For that, you would need an older style LS1 ECU that will work with a cable TB, and use the LPE Conversion module to make the older ECU work with the 58x LS7.
