Those are the maps, just people are labelling them differently.
90550001 is a fairly bare rom from what I have seen. It doesnt have alot of the maps that are in other roms. eg. it only has one set of cranking and post start enrichment maps, whereas some of the Evo8 and 9's have two sets. My ecu is an 8000 series 512k rom and it only has one set.
There are a couple of other maps that are in the same cranking enrichment routine but so far I have been unable to find the exact purpose of them. After finding enough maps to allow startup to be adjusted I stopped spending so much time on it. I will find one of them for your rom later tonight, and you can have a play.
Found it.
<table name="Cranking Enrich Related" category="Fuel" address="3932" type="2D" level="2" scaling="uint8">
<table name="Engine Temp" address="5102" type="X Axis" elements="9" scaling="Temp"/>
</table>

for 96530006 - I will try to realign the table names to what Mattjin started to use and then I will post the updated xml on the ecu wiki http://evoecu.logic.net/wiki/96530006
It's all in this thread: https://www.evolutionm.net/forums/sh...d.php?t=347668
These 2 threads oughtta be combined, they deal with the same issue — cold start, one has to do with AFR, one with timing...
In any case:

I decided to leave the numbers raw just due to the fact that you end up with messy decimal place numbers rather than just more easily considering it a control factor.
To clear up what the maps do. Cranking first pulse is the first type of enrichment when cranking begins. It then switches to what the aftermarket calls a Post Start Enrichment which is labelled here as a Post Primer Enrichment because it takes effect as soon as the cranking pulse has finished. This adds fuel to the normal mapping and it will decay (reduce over time) this enrichment based on the decay map. I am yet to thoroughly investigate the load control map but from initial testing it will reduce the effect of the post primer enrichment under heavy load to prevent running too rich (enrichment not needed at this level of airflow).
So if you car is hard to get fired up, play with the Cranking map. If it fires up and runs crappy for the first few seconds play with the Post Primer maps.

Ah, thank you. I stopped paying attention to that thread. lol... never know where good info is going to crop up here.
lol my 94170014 XML just exceeded my evo7base XML in size.

Well, those definitions come from this thread: "cold start enrichment table":
https://www.evolutionm.net/forums/sh...1&postcount=40
or
https://www.evolutionm.net/forums/sh...&postcount=126
And when it comes to "boost enhancement" table i just looked at these posts in this thread and changed the scaling of the table to timing:

A couple of questions on cranking.
1. Has anyone logged cranking and seen a one-shot "wetting primer" that was longer than the cranking pulses?
2. Has anyone logged the cranking pulse-width reduceing? Not refering to post crank decay here, just while cranking.
The reason I ask is Motec/Autronic/Wolf and I think Haltech all have a seperate wetting pulse to the cranking pulse, and I think you can make the Motec cranking pulses decay as the manifold gets wetter, preventing flooding.

1. That is what the 11-element Cranking First Pulse map is for. It is the first shot of fuel when you start to crank.
2. Immediately after this, it uses the main maps and also starts using what all the (aussie) ecu's you refer to call a Post Start Enrichment. Had to mention the aussie bit ;-) Even though it hasn't officially started yet it still starts enrichment and begins decaying. I probably have more experience with Haltech stuff than anyone on the planet, and they definitely use a couple of maps above and below a set temp that allow enrichment amount based on a time after starting axis, and also timing advance vs time. The new platinum stuff can be mapped vs engine temp in the same way as the Evo does, but in 3D rather than 2D vs 2D.
On a side note I found the purpose of another two maps. They control the startup delay of the O2 sensor from turning on closed-loop. The delay is based on engine temp and is done to allow the heater element to bring the sensor up to operating temperature. The max time we can set (255) is 2 minutes so I created a new Delay Time scaling which seems to be working. The map is fairly pointless unless anyone has specially changed 02 sensors. I always knew the maps were related in some way to closed loop and a little playing around today showed what they do.
Also while playing around I found a map that had a definite effect on acceleration enrichment. I am start the discovery of those maps over the next couple of weeks.

Mattjin, point 1 satisfactorily clarified, great.
Point two, Post Start Enrichment. Is this %enrichment of the main map, or milli-seconds? Lookong at the units and past experience say it could be either.
I love getting stuff like this quantified.

I was looking at my cranking IPW in Evoscan yesterday. First shot looks to be ~6ms, then immediately it drops to ~4, then to ~2 where it settles for a bit and then goes down to ~1.7
Playing with cranking IPW adder/primer enrichment didn't seem to change that at all from what i was looking at. I couldn't change that first ~6 reducing or increasing any of the values in any of those enrichment maps...... i wonder why.

You will have to check its exact purpose. Zero the map and see if it still injects fuel, that would be the easy answer. Be sure to disable closed loop when doing all testing too, especially with anything to do with fuel. Easiest way is to just set the temp control for it to above a temp that you will ever see (I use 110C)
