Honestly, I'm not sure yet. I'll be running this motor N/A for a bit to break it in and save up some $ for engine management. I'd love to go with AEM just a little iffy on how parameters and whatnot will work for stock function like A/C. When I had haltech for my genesis coupe, it was FANTASTIC, however A/C was a little iffy. Id like to basically keep all stock parameters with the option to change whatever I needed to in the ECU for tuning.
ac operation on an AEM in any S chassis is as simple as a switch input for ac request and a low side output to ac compressor magnetic clutch. All functions including idle up and previously said inputs and outputs are plug and play in the S chassis aem boxes.
I had a customer with a haltech and a genesis dont let the experience sway you. The AC operation/control in the haltech was fixed with some updates from what i remember. The way that vehicle controls the ac was monitoring the pressures of high and low sides. I'm sure the factory ecu monitored that and had some other timers involved to control it. I ***** hated that ecu. They put it in the engine bay with no way to control the ecu's temperature. In the summer time, it would lock up the ecu and delete the firmware and tuneup. I had to have it sent back to haltech to fix it once. When it came back i had the customer buy an extension harness and we put it inside the car never had a problem again. I will say the fuel maps are huge which is a big plus for any car that has valve timing control. The genesis has a unique/piece of **** intake manifold and makes NOOOOO power/torque without properly tuning the valve control. The valve control is being used right outside of idle and fueling changes are huge in short amounts of rpm.
but i still hate the box and the support structure of the haltech.
If you are building a setup for gas OR e85, ecu options are easier. Just have to have two tuneups.
If you are building a FLEX FUEL setup, gonna have to go with AEM infinity or series 2, haltech, pro efi (good luck getting support if you're not a dealer), motec, ect ect ect
