EVERYTHING I posted last night is garbage.

The IAC was broken, the idle control screw was open, etc etc. I should delete that post, the information in it is BAD!

Today I put in the the new IAC that arrived today. Wow, instant response when I changed thing on the computer.

I'm using a frequency in the 300s. I tried a low freq and the IAC did not like it.

Totally closed the idle screw. Then started experimenting. The car simply would not start for a while. Then it started, and eventually I got the hot idle to be sitting pretty happy at ~1050 rpm.

When all the electrics are on (lights, fogs, flashers, wipers), the idle drops a little and hunts a bit, but does not stall. Here is my current setup. As cheap as these valves (~$11 on amazon) are, I may buy another just to have it on hand.

Here is the current setup.

The valve I had was clearly toast, I was probably just working off the open air screw on the throttle body.

Tonight I could change the duty cycle at hot idle by 1 digit and get a significant change to idle. The idle may not be perfect, but at between 1000 and 1100 I'll take it.

Now the test will be to see if it will start from cold tomorrow morning. It should, but I may need to tune the cold start some.

Started right up from cold this morning and settled into a 1200 rpm idle while the engine started warming up. Electrical on or off made no difference.

I’ll take it.

I’d drive it over right now just to drive it but I have the boys and need an extra seat. Lol.

I need to get the 2002 running for things like this. After the divorce I got it so I could go places with the boys.

I’m declaring victory.

In July I sent the car to Translog for tuning. I got it back yesterday. They are a good shop and have a bit of a wait. And Tony himself wanted to do all the work on my car since my cars EFI is not stock.

The first thing they did was upgrade the firmware to one that would work a little better with Aircooled cars. In particular the Coolant Temp was not capped at 200, but would happily register temps that would melt my heads.

The car is running great. I had to change a couple things, in particular Tony did not understand the IAC function with the resistor, and said he did not want to charge me while he learned it. So he set the idle with a bolt, and I reinstalled the IAC last night and got the idle tuned how I want it.

Today I took the day off for some kid stuff. Once that was over I put about 100 miles on the car, with my laptop so I could pull over and tweak things. It did fantastic!

Yup. Calling this a win.

Hopefully I’ll see some folks at Ski Roundtop tomorrow for the Aircooled meet.

Even Gave it a nice washdown for tomorrow.
My kids noted after my drive today “wow your 914 sure is dirty!”

They were right. It was due.

So which IAC are you now using? I am still having idle issues with my microsquirt conversion but other than that it sure runs well. Would you mind posting your msg file?
Thanks,
Jule

I’m using the IAC out of a Hyundai Sonata. It’s a simple (and cheap -$11 on Amazon) PWM 3 wire unit. It works really well. I’ll post the MSQ file in a minute after I boot the tuning laptop.

@rudedude

Zach's latest 914 MSQ file

Its very very close. Completely driveable. It will sometimes pop through the intake on cold start, and I'm still tuning that out. But one it starts I only have to let it warm up for about 30 seconds before I can drive away.

Thanks! Now I have to figure out how to read the file and compare what I have done. Soon it'll be running well and then put away for the winter
