I's been hell for me trying to get the car to warm up and idle correctly and I've had a whole weekend to work on it with no progress. The cranking PW's that came on the 90-93 pnp seem to work well enough to start the car (I have 240cc injectors) but right after it starts it goes super lean and the idle is at around 2000. Now I've been messing with the cranking pulsewidth after the car started to see if that would help, but I put those back to what they were. From what I've seen and read the cranking PW's are only to get the car started. What I need to do is work on ASE and WUE. Now this morning I was messing with the settings long enough that the car was up to operating temperature and the idle was still really bad (super lean at 2000 rpm). Any suggestions? The temperature is between 35-40 degrees now.

 

You need to dial in the VE table first, otherwise you'll never get the rest right. Warm up the car then do some datalogging and feed it into MLV. Once your car has a nice VE table you can then fiddle with ASE etc.

 

I've actually been tuning my car repeatedly over the past week and the VE table is prett good. Although with that mentioned I do have issues with my idle. I'll be driving around and I'll let off the gas and the rpm will drop really low, like 400-500 and then jump back up to 1000 before settling down. Any ideas on how to adjust that? I've got a linear tps, but it doesn't seem to help.

 

I run the values DIYautotune uses, never made any changes and they work great it seems. A little rich, but that's the least of my worries.

 

I made the ASE timer a bit lower so it goes to WUE quicker, seemed to stop the crazy rich smell I had after warm starts. My economy is better now too but I have changed my AFR targets and some other stuff at the same time, I don't know if this contributes to better economy or not.
