So I just got s300 v3 and had a buddy help me out with the tune so far, started with a base map and went from their.

Its acting funny when I'm trying to cruise... the air/fuel goes up and down and the car surges... and not sure whats not setup in the tune to fix that?

Anyways....

Here's my setup...

b16a2 block
gsr head
skunk 2 intake manifold
AEM cold air intake
greddy header
2" exhaust (installing 2.5" system the next few days)
Stock injectors
Fuel pressure 42psi at idle

Any help would be cool, I'm new to the whole smanager tuning and have an idea what im doing, my buddy thats helping me has used it before but been a few years and is mostly a toyota guy.

Thanks

So i got the new 2.5" exhaust on today and took 2 more data logs driving.

I personally would have started with a B16A base map being that the block is a B16.
When tuning it's best to tune in open loop.
If you are using a wideband it's best to connect it to an input other than D14 to get a wider range.

Ya? what input would you suggest I hook up to then?

Definitely needs some work.

Use my tune from this thread as a guide.

Try D10 ELD

on d10 would I disconnect the wire from the obd1 to obd0 jumper harness and connect? like I dont need eld going to the ecu anymore?

I was going to use that spot but was confused on weather or not to do that.
