Why does my WUE only at 100% all over after Autotune?

Hi again, here i come with some stupid questions "Again" with my L28et, turbo Datsun.

I have made 2 tunes one with 2 squirts simult, and 2 squirts Alternating. On the 2 squirt simult. the WUE tuning is "Normal" after used Tune Analyze Live, but on 2 Squirt Alternating the walues goes to 100% all over the board after Tune analyze live. Why is that? 

Im posting both of the .MSQ the one called "NR2" is simult. 2 squirts, / and Stock.MSQ is the one i would like to use.

I bought new injectors before i started, can someone give me the correct Dead time on 13.2V, see the picture added. its only 4 injectors there but this is a six cylinder, they just forgot to send me the last 2 injectors. (I got them now offcourse)

The picture wouldnt upload it was to big even tied to .ZIP it down. So im writing the values from the scheme here:

Volts: MS:

8 1.049
9 0.947 
10 0.846 
11 0.764
12 0.682
13 0.616
14 0.550
15 0.484
16 0.418

I tryed to switch the "stock.msq" from 2 squirts to 6 squirts alternate to check if the AFR went Lean or Rich, it went Lean directly and the motor died almost right away. It idles pretty good at 2 squirts alternate. 

Im also posting my .Msl from startup today, there you can se that i also get "Lost sync error" 

On the stock.msq i have tried to make two tables with Kp as switching point, Table 1 for cruising and Table 3 for Boost. Its not dynoed yet, but i wont to have all settings ready when i get to the tuner so they dont have to use alot of expensive time to make the settings correct. 1 Hour of tuning here in Norway is like 230-250$ and its not many over here that knows Megasquirt in and out. I do not want to be the one who pays for theyr education to learn MegaSquirt if you follw me. 

The GM IAC is working pretty good, but the total closing step is 313, have i set the Cranking stepper settings correct? Im not sure i have..

And the last question (for now) im using ms 3.3.2 version, and the ASE Taper time is in Cycles, does this mean one cycle is one turn on the engine? I have seen some other .MSQ have seconds instead. If you count 100 cycles on idle lets say 750RPM how long time in seconds is that? Yeah i know Stupid is stupid does.

Thanx alot for all you guys that have plenty info on everything.


Does anyone want to make a Remote Tuning Live, and with that i mean i let you have acces to my laptop with 4G thrue internet, and i call over to you with a seperate phone while im in the car while driving. Like when you have live support from example Microsoft. That would be a funny test. I can even pay for the time been used, if you have the skills to do it then, not a garage tuner like me. :wink:

You have several different questions all together, and some of them are pretty esoteric.  Looks like a big mess to get involved.

 

- Warm up enrichment (WUE) at 100% after autotune.

 

- Lost sync.

 

- Injector dead time.  Apparently the table of voltages can be used to calculate dead time?  You're asking someone to do the calculation or asking for the formula?

 

- ASE taper time.   What's that?

 

 

From what I've seen, many people don't even use Autotune.  It changes things that you might not really want changed.  Most start with a basic known tune, then use the datalogs to make manual changes.  Autotune is for the end when you're almost done tuning.

 

You'd probably do better by listing the specs. of your engine and components, and the specs. of your Megasquirt system, then using one of the tunes that people have provided on the forum, to get started.  

 

Just offering an outside opinion.  I don't have MS so can't even look at the three files you attached.  If you have Windows you can use the Snipping Tool in Accessories to capture a screen shot.  Might be easier than creating zip files.

With a lot of these questions, you need to go to the MSExtra forum . I skipped all the batch fuel setup and went straight to the the sequential setup where there is no question about fueling, one squirt per cycle, easy. I didn't mess with Autotune for warm up. Just got a good base tune while warm and figured out the best AFR during warmup to what the motor liked and sounded the best and tapered the enrichment till about 160 degrees. 70c? Not sure of that conversion. I run about 13 to 1 AFR till warmup. Of course since then I have switched to MAF and most of the tuning challenges seem to have disappeared. Its like speed density is a delicate balance of many variables to calculate fueling and MAF is just measuring air, that's it.
