what was your final settings ?

thanks Bob

 

Same as prior page

 

Held idle 2nd day after cold start ...a/f purrrfect

 

I did log quite a bit before the switch but not in kpa in psi. So i've been doing the math to convert it over and get aproximations. I will keep messing with it some more as I drive around more.

Where can I find the conversion for Farenheit for the MAT readings, I'm obviously hitting celsius. My search button wasn't bringing me what I needed! I also have skimmed through almost all of that install thread for it and a lot of the SD thread by fred.

Thanks-

 

I only have the MAT scaling for celcius.... The formula Is the same 1.8*x-40 which should be for celcius.

 

celsius doesn't do me much good thats what I already have. Weren't you saying there was a conversion floating somewhere around for farenheit? Or is everyone just watching celsius? I guess as long as the car can register it for SD that's al I really care about.

Getting closer after tonight to getting a smoother fuel curve like before the sd switch. Did a quick pull for a brief 19 psi and afrs looked alright around low 12's 12.0-12.2. Need to tweak the drivability as still goes back and fourth form lean to rich in different areas. Car feels a lot crisper now on SD than before, felt kinda choppy on and off throttle.

 

Also log O2 feedback during cruise to make sure the car isn't pulling or adding fuel. WOT should be the top 2 cells for map VE.
12.0 a/f @ 19psi. Add about 5-10% fuel for the top 2 map VE, log and add 1/2 points in the RPm VE if your still a little lean. What boost do you normally run? And what a/f?

If u need extra help post up your VE tables and a WOT run where it goes rich after shifting.

 

Oh the only thing i've read for Fahrenheit is 1.8*x+32. See if that works.

 

Awesome!! I'll give those a shot. I've still been screwing around with it, but the ambient temps are swinging from 30's to 60's and it's totally throwing me off as my results are different every day.

I'll give that a shot and see what happens.

Thanks!!

 

I got a chance to try it out today. The car still stalled out after starting a couple times, but it seemed like it took less time feathering the throttle before it would hold idle. I'll try increasing some of your values at lower temperatures and see what happens. I'll keep you posted...

 

I think I asked you about morning temps a few days ago. Mine range from 75-85F in the am. Based on your morning temps increase those areas. For the most part I increased 68-90F area which is my local temps.

Tommy,
try changing this before upping any additional values:

MAF Comp vs Coolant Temp#1 & 2(same values for both)

 

Ah, that's a good idea.

I upped some other values, mostly my idle RPMs and it has helped. I'm still idling around 18:1 and it'll often stall after I start it the first time. Still a work in progress.

I like that thought though, I'll give it a shot.

I have a question for you about speed density kpa/load table. Should I post it up here you think?

 

Shoot away. Just watching lakers play Suns.
