The Ultimate A/C Thread For Pigs! (Air Conditioning)

The idle speed control valve should open up a bit under the compressor load and at least try to keep the engine idling around 650rpm.

FJ62 and FJ80s didn’t cut the a/c off when at idle. The ecu has the ISCV compensate for the load and attempt to keep the idle speed at 650rpm.

I don’t think your ISCV is working properly...

The A/c on signal to ecu from amplifier just raises the desired idle speed to make the a/c system more efficient and blow colder. Compressor spins faster, and fan moves more air over condenser.

Thank you! That helps confirm my suspicions.

Looking forward to your product!
 
I have a solution for integrating factory a/c to an efi motor; to get rid of the idle speed cutoff function.

Perfect for a piggie with a diesel, or an efi motor that can control idle speed when a/c is on.

It works without any coil input(rpm) but still allows stock thermistor and temp dial to set temp.

More info to follow. Going to build a few for sale, so I will need to get a star. Will include controller box and a small wiring adapter, with or without a wire to integrate to ecu “a/c on signal”

Definitely works with 73 and later systems, but I am going to create a slightly different harness adapter for the 70-73 style.

If you come up with a stock underdash unit, without wiring or controller I can also get you functional with this and a new harness.

Did this used to be a separate thread?

Any updates on this?

Thanks!
 
Would one of you 55 guys like to own a very good condition A/C manual of your very own? 60 bucks plus shipping.

They are $19.99 plus shipping from SOR. Just FYI.
 
I thought I had posted a link in here for hose ends that will allow custom hoses to bolt up to Denso compressor manifolds.

Does anyone know where to get these?

Wonder if these would work?

I would also like to know if they work. I hunted for weeks for metric hose parts and came up dry.

When my hoses failed and the mechanic said American hoses would not swedge correctly. I had a machinist cut off the hose side of the fittings and weld on American swedge ends. When the machinist was done one could not tell it had been done.
 
This is a great post , Thank you PabloCruise for your post all the information I needed. With that said Iam going to push the golden buzzer button. TTT

Glad I could help!
Maybe we could get the mods to merge the two threads and sticky...
 
I guess I have not been keeping this thread up very well.

I have some good details about my AC progress (or lack thereof) around here:|

 
Here is where I measured the opening (wait, what?) to see how big of a condenser I could fit:

Everyone needs a chance to see @Spook50 rebuild a Denso 10P15C AC compressor:

 
Need information on sanden compressor, I have the mount for a sanden compressor for a 2F, but not sure which one that will take the larger stock 2F belt. Any help appreciated I have this bracket
