LTFT moving in open loop (O2 unplugged)??

considering I have 100's and my idle puts my IPW's around 1.8... It doesnt work below 2.0... which believe it or not is excatly 1.3(min pulse)+.7(offset).

Yay.
 


it "should" be 1.8 but never makes it there. You can watch it march down from 2.7 during warmup and stuff, then hit a wall when it trys to command under 2.0. It then starts jumping between 1.3 and 2.0 causing a crummy lumpy idle.
 
Thats pretty crappy. Are your injectors controllable at pulse widths that low?

Using your math I should not be able to go under ~1.6 ms yet I've seen as low as 1.56 in transients, however typically ~1.7 at idle. This is with 70 lb injectors.
 
So how did you lower the pulse widths that low.. Mine still runs rich in closed loop under decel in 4th gear.. If your high enough in the rpm it'll go full into dfco but for the most part the lowest it'll go is 2.136

Click to expand...

Use large injectors.

Define rich.
 
I'll throw a scan up when I get home tuesday... It runs perfect everywhere except 35map and below.

Here is a Scan.. It's a short one showing going down the expressway and tipping out of the gas then back in..
Any help would be greatly appreciated.

Deaccel enleanment.

Try stock settings.

Then try more enleanment.

Also, can you post a log in at least a spread sheet?
 
That is a SpreadSheet.. It's a csv file in txt format.. just change the .txt to .csv or just open the file in excel
The forum won't let me attach a csv file.

Also the stock settings vs map are at 1... I would assume that the smaller the number the more enleanment judging by the other enleanment options.
