reprogramming ecu presentation

[mpampis_]

hello guys, i would like to present you some progress in chip remaping and to discuss about that.

this is the stock map for our 155Q4. and in the left column we can see the air destiny in absolute pressure

the point is that our map can see up to 2.10 bar which means 1.1 bar boost so if we are running 1.1 bar boost, or 1.5, the injection ms and spark advance timing is the same

this is lancia delta's map

we can see that air destiny's brake points are up to 1.59 bar boost wich it gives you the option with a boost controller to run 1, 1.14, 1.44 and 1.59 separately with most suitable injection timing and spark advance for each boost bressure

reading and understanding how does hex working from here (http://berlinasportivo.com/pages/hexmaps.php) i make some changes to our map in air destiny's brake points

this is an 155Q4 map modified by me according to how i want to drive my car
the injection table

and the ignition table

I've always wondered why Alfa mapped the Q4 like this as standard. Give you no room at all to change anything.
Its also strange looking at the difference between the std Q4 and Grale maps to see the differences in injection settings at the different MAP values.

I know when my Q4's chip put together and setup it used the Grale breakpoints with the Q4 data as a starting point.

Doesn't the Evo Grale have a different Map sensor to the Q4?

That's why I change the values. Many times I was using grales maps but with q4 break points. The only thing is that the last grales brake point is 1.59 maybe with 3 bar map sensor. I make for me brake points up to 1.35 as see. It is like I am driving another car feeling free to increase revs very fast

Steve can You please check ECU website http://www.berlinasportivo.com/pages/q4ecu.php
links for q4 xdf files are dead.

I'll take a check of the page and get it sorted. Thanks for letting me know there is a prob.

Should be done now, take a check and let me know if there is still a prob.

It's Ok now.
