and now I'm curious what in the world made you look at the WUE, go "hmmmmmm, lets go ahead and completely alter it drastically" without trying to 1st figure out why it was the way it was in the 1st place.

oh well you live you learn.

protip: when learning to tune, baby steps are the only steps you should take. if you're altering something more than 10% at a time, you should thoroughly question your method
THIS X10!!!

Agreed.

You really gotta have a game plan/method/approach. changing multiple values in multiple places almost always results in frustration and waste of time.

I started with a dIY base map for 94-95. Right off the bat it was so rich I was almost passing out from carbon monoxide in my driveway. Like I said, I will re load it again and start over.

The base map cuts off enrichment at 175* my car runs at about 200. Not a lot different than what I have done.
My question regarding the map pressure on the base map still remains. Why does their non turbo base map have kpa pressures to 240???

I have read the mega manual quite a bit, some sections over and over and over.Some things are just different. From the first start of my install, following their directions exactly when trying to hook up my AIT sensor, per the 1995 1.8 section It said " connect to the yellow and brown wires" I do not have yellow or brown on mine. Differences like that make it hard for me to follow direct instruction.

its scaled to 230 cause they're lazy and it won't make a difference much and you'll be re-scaling anyway. their base map is just to get the car fired up and able to at least get on the road.

temp scaling is not what screwed you over, changing enrichment % from 100 to 0 on the low end is what we're pointing out to you.

I can't see the msq though since at work, so I'm just going off what was posted

So should I be hitting 100% at like 150 deg.F. and then run it out past 200 deg. F at 100%?

Something like that. 100% = no extra fuel, >100% = add fuel for warm up. You should not have it go below 100%, that definitely sounds like what is causing your problems.

yep, 0* = 150 or 130 or whatever
tapering to 150* or 180* = 100. never less than 100, and the taper needs to e really smooth,

Yeah one of the downfalls of the Reverant ECU is that the WUE was perfect out of the box, so I never learned how to tune it.

One of the reasons I'm looking forward to tuning the truck, I'll actually have to learn all that ****.

Thats debatable. Though it is very good WUE changes depending on several values in your tune. I save the fine tuning of WUE till Im practically done tuning. Usually Ill do everything but WUE and wait till the next morning and tune it while the car warms up.

Mine turns off around 155-160 cause I run more fuel at idle to help with hot restarts at 160+ and use EGO to lean it out. With seq Im warming up at 14.3-14.7 then idle at 14.5-15.3ish

Cant you tune the hot restart leanness out with ASE, thats on a timer isnt it?

Yeah but you have to run it for a lot of time. I still run ASE but as soon as it kicks off EGO takes over. Not necessarily the best method but it works good for me.

Started again with a base map from DIY, smoked out my whole neighborhood. Went fo a short drive to let autotune take over for a bit. Back to the same place I was three weeks ago with an idle that I cannot get below 2200. I am back on open loop now.

I made a block of the timing at twelve just to make sure that I wasnt getting any influence from other cells.

Idles at 13.9 AFR @2200 rpm.
How is this engine even running??-screenshot-9-.jpg

Well at least your fuel map looks somewhat normal.
What happens if you go into idle valve test mode and close the valve completely?
You might have to close your idle screw a bunch.
