ECMlink First start help.

[YawnY]

I just got my car running in the fall and haven't spent much time on it since my son was born. Got the spend a couple hours chasing boost leaks and getting my boost gauge/wide band installed. Got it up and running but have a high fluctuating idle. Boost leak check was good, no leaks.
I'm running ECM link v2 with a 2g maf, a 255 pump and a fpr adjusted to 37psi, denso 750 injectors, comp cams 101 and a 16g with a fmic

Any help would be amazing!

Pretty strong example of idle surge once it warms up.
I'd keep looking for boost leaks with a pressure test and make sure your throttle butterfly is closing all the way at idle. Also make sure you see the TPS voltage swing is. Log just pushing the petal up and down.

Why don't you log/have an IPS?
I didn't see a configuration (maybe missed it) for Narrowband O2 simulation. It's been long enough for me too forget is V2 supported it.

Does the car have a stock Throttle Body?

I'm assuming it's a 1G but if you posted a profile it would help.

Thanks for the reply.

Tps voltage does swing from 0-99% with the appropriate set voltage at the tps. I have the ips switch disabled.

I'll have to check on narrowband 02 simulation!

Stock throttle body but I have the coolant paths blocked off. I read last night that it can cause an idle surge if I don't block off the paths with rtv, so I'm going to try that, then do another boost leak check. I had just made a block off plate for my egr because it was leaking when I did my last boost leak test.

I'll get my profile setup asap.

Again thanks for the help!
