Another couple quick questions on LFX parts...

I saw a link to summit on here for a new LUK LFX clutch kit and now can't find it for the life of me. Anyone have a link?

Also, what are the correct GM part numbers for the flywheel bolts?

 

11588884 - 8x required - annoyingly, even the LuK kit came with the automatic bolts(!?!)

You rock! Thanks Brother.

 

Finally found a salvage yard on car-part.com that would confirm the ECM came from a 2015 camaro V6 w/ a 6-speed manual and were willing to ship it for $75 total. Amazing how many told me they wouldn't ship it out of state. Wtf?

 

Erm - crap, 2015 is gonna be an E39a ECM, and might have issues with the alternator control.

 

haha, I just can't win with this.

If it is a 2015 engine and 2015 alternator why would there be an issue?

 

Needs the BCM because of course we had to make the alternators too damn smart.

The DR44 alternator (2 pin) has a field and a sense wire. The E39 with hptuners and alternator override will default to 13.8v output. E39a's wont enable the Field wire, which won't produce voltage. I'm working on a simple 555 timer circuit that'll produce the right 128hz PWM signal, but I just got around to designing it last week.

 

Got it. Okay, please treat me like a 5 year old for this so I don't **** it up again.

Is there a specific year 6-speed camaro 3.6 lfx ECM that is guaranteed to work?

And do I need a different alternator than the 2015 model that comes with my engine?

 

Serv #: 12643248 - should cover 2012 Camaro, has PN of 12648906 (E39), with a VIN of 1G1FE, 1G1FF, or 1G1FG (indicating manual transmission). Annoyingly https://service.gm.com/dealerworld/v...013%20r1.7.pdf doesn't appear to be loading. edit: https://www.camaro5.com/forums/showthread.php?t=266853 has the decoder.

Alternator should work, it's just the control is different.

 

Yeah getting the salvage yards to give me a vin from the donor and confirm the details and ship is going to be a mess. I see why this is such a nightmare now.

Thanks for the help Brother!

So far the salvage yards think I'm a moron and are telling me I have no idea what I'm talking about. This is gonna be fun.

 

Score!!!!

Okay, so a bit of advice for anyone trying to track down an ECM for a LFX swap...

Go on car-part.com and search for a 2012 camaro 3.6 engine. Look for an engine that shows it as being a 6-speed manual car. Hopefully they show pics of the car in the images and you can confirm the vin. Call and get the ECM.

Totally lucked out and found one 20 minutes away in Austin. Just went and picked it up on my lunch break. I saw the car and it was indeed a 6-speed. The vin pic I took at the actual car. Btw, if anyone needs a vin for any reason on their ecm, feel free to use this one.

Please tell me this is the right one...

 

Hurray!

 

Besides the Miatas I have a C5 Vette, and I gotta say, GM and their electronics...what a huge PITA they are.

 

Anyone know what size bolts to use to get the LFX on an engine stand?

Edit: Found it in DJWade's build thread... "M10x1.5 x 75mm is what you want if you're using a harbor freight/torin engine stand, or at least the 'T' leg version"

 

Running into an issue trying to find the trans housing to engine bolts.

Portabull listed the part # as 11515770 in his build thread. That is the same part # I'm seeing here:
https://chevrolet.7zap.com/en/camaro...7923382-0-0/#4

When I go to order them though, they show as alternator bolts on every website and nowhere else do they show as transmission bolts.
https://www.gmpartsdirect.com/oem-pa...-bolt-11515770

Can anyone confirm if those are the correct bolts?

 

Looks right to me. And a tip - the pennies you save buying from gmpartsdirect or similar is lost when you need to return them - I never heard anything good about them. I made friends with the local Chevy parts counter guy (well, annoyed him lots) but he always returned the parts that don't fit with too much fuss - though waiting a day or five to come from the warehouse (depending on the warehouse). And GM's complete parts listing isn't online - parts counter guy has a better resource that - but to speed things up, have a 5spd camaro VIN handy. I would usually find as many part numbers as I could, then rattle them off to him and verify they were more or less correct on his screen as to the application.

 

Yeah, I'm finding parts lookup online to be a bit of a pain in the ***. Many of the parts I'm trying to look up either don't have an image or are buried in one of 20 different parts diagrams that only show a tiny drawing of the part. Then I google it to see if I can find a picture on ebay or somewhere else.

Thanks!

 

Found a gem... Chevrolet Equinox Service Manual - Engine - Powertrain

It's for the equinox, not the camaro, but this site has the full service manual for the LFX on it. I was struggling to find some torque specs and replacement procedures for a few parts and this had it all.
