Megasquirt I v2.2 VE tables

[Hiro]

Hi to all,
Maybe it's time to centralize what we know about Megasquirt for our CIH,
So I start with my VE tables to be downloaded here:
http://www.rroc.net/Techniques/Megas...5_180_160a.vex
Just change the last name for the table you want (see below).

This is what I have available uptill now,
Nothing was dyno measured,
I tested only a few tables so it's all ongoing work.

Table nomenclature:
example: 25_160_145a
25_ = displacement
160_ = output hp
145_ = torque lb.ft
a = variation in idle rpm or max torque rpm

The 20_ & 24_ tables are for stock CIH,
The 24_ table works better in my hands both for 20E & 24E.
The 25_ & 27_ tables are for race CIH,
The 25_200_180a table was the start point for my 2.5
This table was further modified above 4800rpm to get a reasonable functioning,
See next post.

Sorry the table below is difficult to read,
Word text... columns are jammed,
Table list & name is:

25_160_145a.vex
25_160_145b.vex

Now this is what I'm working on now for my race 2.5
They are all variations of the initial 25_200_180a VE table,
I've manually modified the values above 4800rpm,
Using the "tuning" function of the Megatune software.
I had no time to test these new VE tables but one,
The denso3a1_5 was better uptill 6000rpm,
But I could not run WOT yet looks still lean at high rpm.

fast update after some tuning at the Le Mans vintage GP:
the 3a1_8 VE table gave quite nice results with my race 2.4 CIH,
still too rich (WB EGO says 12) but runs OK until about 7200rpm,
getting closer...
