That?s more or less the advice i was looking for. I?m getting it as good as I can on my own.

It?s built for Nitrous. I?ll take it to a dyno and get some more experienced help once that is...

Ride on - I was at 13* on my last drive around. The delivered torque value peaked about 1,000-1,500 rpm earlier than I expected with the cam.

I?m still going to be safe and add timing just a...

What's a typical spark advance range at WOT for these gen3 engines? N/A tune, not interested in timing for boost or nitrous for now.

I pulled timing, and added fuel for my first few test drives...

I assume you knew to "write entire" after you turned the VATS off? I've made that mistake before. It would crank, fire then immediately shut off.

I don't see it anywhere. I'll post tune as well - maybe I've overlooked it. To get around not being able to change the switch type I followed the information in this thread about wiring pinouts 32/34...

That was the VSS sensor I had looked at.

I see where I can choose a non-electric auto from a drop down but I don't see a drop down to switch from PRNDL to PN only. I've got a '99 computer with the...

So the IAC is acting up because the computer can't get back into the idle routine? What in the follower/cracker settings would be causing it to stay active?

I have a modified LQ4 swapped into a 1980 k5 with a TH400 behind it. I am tuning OLSD. Currently I do not have a VSS signal, or a gear selection signal. I can see that I need VSS for throttle cracker...

It worked, Thank you!

Long story short I had increased the follower at one point and never moved it back down. I was in the process of decreasing the follower airflow as I suspected I had too...

I am running into an issue where when I release the throttle the IAC sometimes gets "stuck" open. The engine will sit there and run at 1200+ rpms until I shut it off. It doesn't do it everytime, but...

I got it to run from cold start all the way to operating temperature before the motor died. Thank you to everyone for the help so far. The tune is definitely getting better.

Something is changing...

well fixing the injectors seemed to help a lot. it still dies though. This is about the best i've done so far. I can't figure out what is causing it.

I opened the throttle blade until it would start, the IAC goes to 0 in order to slow the idle. I tried less Base airflow but didn?t seem to make a difference. Also tried adding/removing spark. The...

oh okay That makes sense now. I guess I had it in my head that the IAC vs effective area table worked in conjunction with the etc area scalar. Thank you for clearing that up.

This might be a...

I'm looking for advice getting a stable idle. The engine starts when cold (not smoothly, but it doesn't die). Around 80-90*F ECT the motor dies everytime. at that point it will only restart with some...

I have extensions and it made a small difference. I think the O2?s not working has more to do with Cam overlap at idle. I have about 16* overlap at .050.

I found abuse mode, and will turn it off. Regarding the MAF being off when tuning VE. I don't fully understand what you mean by data being skewed. I had only been changing VE at 1600 and below RPM,...

Fuel Injector data should be correct - I copied and pasted from Deatschwerks website. They are 60lb injectors. Changes to base running airflow were made to reflect Idle desired Airflow - I thought...

I am still working on it, this is the first engine I've built, and attempted to tune. I think there is a saying about tuning being a process not an event, and I have definitely...

I'm working on a 403 stroker tune built out of a LQ4 block. The engine is on a stand and I have been working on the idle. When I blip the throttle the engine will either bog then rev or just die if I...
