It seems its time to release the patch publicly...
mad scientist ...thanks...
)))
--------------------------------------------------------------------------------
This patch has VE table, Temperature compensation table,MAP calibration table.
There are 2 versions 1- limiter version -as I'm using everyday on my rom where map is limiting mas signal -so it is scaled to be a bit rich running on map - and a full version which lets entirely eliminate MAS sensor - but its temperature input is still used for temperature compensation - the ideal is to put the temperature sensor into the manifold and put it to MAS temperature input.
Also disassembly masterpiece included. Not very detailed as for my ecu - but better than nothing.
If you still have MAS connected you should try the limiter patch - you can log you MAFSOURCE_MAIN signal - goes from MAS in limiter patch and compare it to MAFSOURCE1 signal -emulated by MAP. Than getting ve table you could swith to MAP entirely.
Dont forget to copy your tables to patch and correct the accel enrichment.
Also dont even try to start this without having wideband..

You can ask questions to mixmastermatt cause he tested this patch ...
Will not answer in PM this patch - related questions -ask here...or at aktivematrix same thead....

UPDATE:
Car is back on the road with a new 5-speed transmission. While it was down, I pulled the intake manifold off and drilled out the bung for the IAT sensor. I'll be wiring the GM IAT sensor directly to the ECU and compensating for any temp differences in the ECU. As for the baro, I think I am going to try to use the stock MDP sensor and rescale it to match the typical voltage output of the stock baro sensor. Hopefully I'll get a lot of testing done this weekend.

Aw so that means you wont be sending me that mdp sensor? ahaha I'm kidding lol, but that is cool, let me know how it goes. Are there tables already defined in ecuflash to compensate for the iat voltage. I know the baro table is there, but I havent seen anything for IAT Calibration.
If it doesn't work the way I expect it to, then I'll send it to you. I meant to PM you about it, but got caught up in work.

It uses 3-bar MAP connected to MDP input -doesnt matter JDM or from Apexi boost conteroller or othe 3-bar - the're all linear 5 volt ...
The baro In mas and temperature input are required to work without CELS- so at least put resistors there...

Hey bez I am using the same sensor you are, which is the motorola mpx6300a, I was wondering did you add any resistance when you wired yours up. I measure the resistance and the difference from the stock sensor is about .30 should I still add a resistor? So far it seems to be fine and pretty close on target. Nevermind, I see what you are saying which is regarding the other sensors(IAT and baro).

There is no resistance in sensor - it outputs voltage...Dont add the resistor...
I compared JDM map mand MPX6300 -almost the same - a little difference is compensated with offset -85 -100 in our case

Yea I know, since 94170008 is so close to mine 94170014 it would be much easier to port the information over to my rom lol.
Man I opened bez's rom and my rom and tried to just copy the code information from the map addresses shown in hex,(could kinda tell where the map patch began, right after his MUT table) since it looks like it was just added code in the empty spaces FFFF area (im noob at this coding stuff) and i tried to changed the address for the tables based on where i pasted the code in my rom, but the rom would no longer open
any suggestions smart guys. The only reason I figured I could do it this way is because when i added the info to the xml file it showed me the charts but was incorrect because of course the addresses were mapped incorrectly. 
Any help will be great ahahah

mm this would be the cat's ***. I too have the 008 (03 viii) might hafta sit down with ida and a few other toys and see what i can glean. probably time to move ida off my desktop and onto my laptop, maybe play a little at work
