Can I apply turbo spark tables, up to 100kpa?

 

A turbo car even at 100kpa will be flowing more than an all motor car. (lower spark values)

Depending on the turbo, some will flow more than others.

Pressure =/= flow

 

A couple hours searching has only resulted in a few spark tables that don't seam to apply to my build.1995, no turbo 1.8.although don't expect anyone to just hand one over, some simple direction towards one would be awesome.

searched-
spark table, good spark table, solid spark table, can i see your spark table, spark, na spark table..
Am I just this bad at searching???

 

Here ya go

Conservative spark table - pretty sure it is the basic MSPNP table

 

I did have this one. It just seemed like a REALLY conservative map. 14* at wot just sounds weak. I guess I need to search more along the lines of how much spark is beneficial. I think I remember seeing something like that a couple weeks ago.

 

You will never reach that part of the map as N/A. Notice the kpa on the left is at 230 which is ~19psi. You will only ever get to 90-110kpa from and N/A engine depending on the altitude.

 

Ha! That makes sense. I will plug in those numbers today.

 

One thing is unclear to me though. If my map is basically 20* static, what is the difference with this base map, besides the fact that it tops out 10* less? Right after idle it quickly jumps to 20 as well. I don't get it. Please teach me.

 

They are only referring to base timing. Which is something you have to set with the factory ecu. With megasquirt you only have to ensure that the commanded timing is what you are actually running.
With the factory ecu picture the above map but instead of the cell saying say 18* of timing it would be like 3* and that would be added to your base timing. So if your base was 14* vs 20* then you add 3* to each and you get vastly different numbers

You would have to know exactly what the factory map added to the base timing to compare the maps. Hopefully this makes sense to you

 

What? As far as I know, you set base timing with the new ms...10* locked then reset ms to -10 and follow map.

 

I was suggesting your map is advanced about 10° over the stock map. Some people cant wrap their heads around full control of the map based on load and rpm and still think in terms of advancing by the CAS.

IIRC the stock 90-97 spark map tops out at around 25° at 100kPa.

 

OK. That I get.

 

So you were referring to the top end of my map and how quick it climbs to 40 and 50*, not necessarily the low end?

 

Update:

The car is running pretty darn good now. I think it is time to schedule some dyno time to find out for sure. good mileage, good power and just a tiny-tiny hesitation off idle (800) when I blip a quick full throttle. I think this may have something to do with the strange map pressure that I have at idle (still unusually high at 40-45).
