'04 5.3L in a '01 V6 Camaro.

The bad news, The PCM still does not recognize the 12v A/C request!!! I could wire around that, But what I found out when I jumped the A/C Relay really made me upset......The Fans do not respond to A/C pressure, But they do to coolant temp.

The A/C head pressure is getting read by the PCM, Makes no since to me, I have sent this PCM off TWICE to fix this stuff to no avail. You would think having my PCM for 2 months total more than one of my issues could be resolved.
I will start a new thread on this, Maybe someone has some suggestions.

Now that your poking around the forum again do you have a update for us on how the Camaro is doing? What else you have done to it (LQ9?) and if you ever got the PCM to control the fans?

Wow.....Didn't expect this! I only posted this here because you guys are like family! I kinda regret leaving the way I did.....But me & another member just couldn't get along!

The Camaro now sports a 6.2L L92 out of a 2007 Escalade....Pretty much stock besides a Cam-Motion stage 3 LS3 camshaft, Hardened pushrods & Bushed rockers. Converted it to 24x/1x.

Ended up running a 2005 Silverado PCM which had electric fans from the factory. Now that HPtuners has the Segment Swapper.....I probably could have got the 2004 PCM to work.

Swapped to a 4L80E & now swapping back to a 4L60E. Don't care what anyone says.....4l80E's are power robbing pigs, If you ain't makin' over 550 RWHP or a really heavy vehicle, Don't bother!

Glad to see you back, miss your great input...Jim

I see you still have a MAF sensor, is there a reason you have not gone with a Speed Density tune?

Pure curiosity. I am gonna run a the MAF, but I thought all the cool kids ran SD tunes.

So happy to have you back!
