2056 Timing, Looking for Analysis Of New Timing Values Options

[Mblizzard]

I have converted my 2.0 to a 2056 and added Micro Squirt fuel injection.

Ever since I did the 2056 conversion I have seen higher than norm cylinder head temperatures. In fact I cracked a set of heads from getting them too hot.

I played around with the timing with in the suggested 2.0 limits of around 27 degrees. but was really never able to influence the CHTs that much with changes in the timing. Adding more fuel at the right times with the Micro Squirt certainly allowed me to control the CHT much better but I always felt it was still getting too high.

Then I ran across this.



This is certainly a lot more advance than I ever added to the engine. So based on that I revised my timing table to:



Just love how easy it is to make changes with Micro Squirt.

So I am looking to see what the thoughts are on 35 degrees of advance and what impacts it may have on CHT. I am going to load this and test tomorrow.

I would ensure the timing accuracy -- make sure your timing light is matching exactly with the computer.

The fact that it idles well with half the normal timing seems like something isn't matched up.

I can't get an engine to idle for shit with 7° at idle.

I get perfect alignment of timing at a 72 degree offest angle. But as you stated crap for idle at 7 degrees.

Went back to James timing table this afternoon. A bit higher CHTs but not a huge difference. James table is much more peppy and responsive.
