Just a little information for those that use the airpump to actuate the 6PI actuators and still have a working ACV/Relief solenoid/Switching solenoid.

I use a spare solenoid and the EGR signal to actuate the 6PI acutators. I run off a air line poked into the large hose b/t the airpump and the ACV for the pressure. It works just fine sitting in the driveway. I can select any rpm I want off the RTEK and it works just fine in the driveway.

It does not work fine on the hwy. Becaue the Relief solenoid opens up under various conditons and bleeds off the air pump line pressure I'm tied into. It might work just fine in the driveway at ?? 3500 rpm, but if you pull that Relief solenoids plug off while in the driveway, then the thing won't open until ?? 5000rpm. The switching signal is still there for 3500, but there's a considerable loss of air pressure in the airpump line. So much that it takes a while to build up enough pressure in the 6pi line to open them. For me that turns out to be 5000rpm.

I doubt there's that many people on this RTEK fourm that use the airpump/ACV/Relief solenoid etc, but just in case, I write this.

I really, really shoulda known better to rig it like this on a bascially stock engine.

Talking series FOUR cars.

 

Oooops. Found the hose has a split in it's bottom side, thereby losing a good deal of pressure. That might be the problem.

 

I'll be doing exactly this with my s4 NA and Rtek 2.0. Please post up if the the cracked hose was the issue.

I'm wired open at the moment, but would like to make the ports useable again.

 

I won't know til warmer weather returns in ??? days/weeks. I figure the split hose must the the problem. After all, the series five uses the airpump to actuate the 6PI. and this is just a copycat of the series five put on a series four car. I'll make a post when I fix the hose.

 

Great! I'm looking forward to it. I'll be sending my ECU out soon for the 2.0 upgrade.

 

It was just the split hose. The car passed emissions with the split in it, but it seems the split was dumping too much air at higher revs. Emissions testing is generally b/t 1500 and 2500rpm, meaning the relief solenoid is not dumping the air from the ACV at those speeds, unlike when your at 3800rpms and dumping the air from the ACV overboard.

 

Good to know it was just the hose. My car actually passed smog stuck in open loop.

I will be copying your setup in the next couple weeks, so I might PM you for more details. Not 100% sure what I need to do to make it all work. I know where to hook up the 6PI line, but what fitting is best to use, and what else do I need to do on top of the physical connection of the airline?

I am ordering my Rtek this week.
