Help with understanding alignment of 4x cam and 58x crank reluctor wheels and sensor

Hey,
Did you ever get this sorted? I am wanting to do the same thing. I assume you are using a drive by wire throttle aswell.

Any info you can share would be greatly appreciated

Also... its tough sourcing a e67 LL8 engine harness... can anyone point me in the right direction?

Thanks!

VERY tough! I'm having no luck at all with sourcing the same thing! Please share any info if/when you get some. I'll do the same.

Just in case anyone has a line on LL8 harnesses, Im looking for an 06/07 P12 PCM engine harness. Doesnt have to be intact, I just need the 3 PCM connectors with a foot of wiring.

Does anyone have any waveforms for 58x/4x yet...?

I recently found this.....I personally wasn't wanting to spend this much on a harness (although I know it's not expensive relatively speaking)........but i figured I would post it here in case someone else was interested.

I gave up on a LL8 harness a long time ago. Impossible to find, and if you find one - they are not worth the price. I ended up with a '08 Silverado E38 harness. AWESOME source for all (and much more) of all of the connectors you need. You just have to re-pin it all for an E67 setup. EFIConnection has been a great source of parts at a very reasonable price. You can re-use one of the E38 ECU connectors - I purchased the other 2 from EFI. If you are reading this thread, you probably have the patience and understanding on how to re-pin the harness.

Good to know, and I know what you mean. Ive been looking for a P12 harness for an LL8 (or even an I4/I5) for the PCM side connectors. Costs an arm and a leg, but building one from scratch to use as a patch harness would be ~$200 and make what Im trying to do not feasible.

Glad you got it sorted out, probably have to deal with the exhaust VVT on a stock LL8 (but for your swap it doesnt matter).

Erik, you have mentioned the VVT issues before and I have kind of ignored it because I obviously wont need it... however, will this cause some tuning issues? I was assuming I could zero out or staticly set the tables. Thoughts?

Thanks!

Im pretty sure you can just go through and 0 the tables out and turn the DTCs off, my hope is the OS wont freak out when it doesnt get any feedback from the cam position sensor (hopefully killing the DTCs will avoid that). Id have to look again, but I think thats the only issue...

tunedportcj5,
Do you happen to have any pics of your process? Crank reluctor and mounting etc?
Thanks,
