I removed my complete AC system, but left the wiring in tact. So I burned a map with a 2step (enabled the AC activation on the 2 step), pushed the ac button, put the pedal to the floor, and it didn't cut when it was supposed to.

I've been doing some reading and read that I need to "jump my AC harness" so it activates the 2 step when I hit the AC button.

Which wires do I need to jump?

You need to ground it. I believe it's D14? I donno it's been a while. I know it's on the Uberdata forums though

bump for an answer because i want to use the ac button for my boost control

there is a plug under the hood behind the passenger headlight you have to jump and one under the dash where the ac radiator thing is... i can't remember any specifics either. the info is somewhere on the uberdata site.

i found some old pics of that might help. i don't remember which ones are jumped in the plug but its something. in the dash pic, you can't really see but there is a jumper behind the metal in the pic.

bigbadboy

ok so jump 2 wires in the plug in the engine bay. and jump the plug that goes where the little rad for the ac is??

EJ1 wilcox

Right on man, thanks for the pics. I have an EF, but I would think the process would be similar. I know right where both those plugs are.

Thanks!

Does anyone know where it talks about how to do this?

I can't seem to access the Uberdata site and I can't find any info on pgmfi.org either.

what the hell i just set the launch control in crome to 1 mph and it was always doing my launch limiter when i wasnt moving, no need for a switch to deal with.

Okay I think I located my plugs, I have an EF so it's a bit different from the pics.

I just have one question. I have two plugs in my engine bay that are disconnected now that I removed my ac.

Both plugs have two wires to them, one plug is for the AC fan, and the other plug goes to some sort of switch that was on one of the AC hard lines.

Is it the AC fan switch that I need to jump? Or the other switch located on the hardline that I need to jump?

I took pics of the plugs that I'll post up later if I don't determine which it is.

** figured it out **

For future referrence, it's the pressure switch that you jump in the bay.

I jumped the pressure switch in the bay, then the two wire harness under the dash, and it works perfectly.

So yeah, you don't have to jump the fan switch, just the pressure switch.

I will be so nice to be able to build boost for my launches.

can anyone tell me where the pressure switch in the engine bay is located on a ek??

On my car, there are two plugs in the front of the car by the passenger side headlight. One of my plugs was green and plugs into the AC fan, and the other plug was white and plugs into a switch on one of the hardlines.

Also, on my pressure switch both of the wires were blue with red on them. They were both the same color. Same with the ones I jumped under the dash, they were both the same color.

Hope that helps!

So you do this and then you can use the A/C button to turn on and off the 2-step in crome?

its for uberdata, i don't think crome has that option.

I don't know about crome but it works like a champ in uberdata. I have it set to 5000 RPMs and I can build 5 psi!

Pretty sweet
