2002 to 2006 Lancer Turbo's W/Automatics that tune their own ECU's
I know there are a decent amount of us base model lancer guys with automatics that have added turbo's. I have already searched throughout the forums and have yet to find anything related to what I'm looking for. That being said, and saving myself the sanity of trying to ask every auto lancer guy here separately, I'll ask it generally and see if it draws out one of us that may be able to help...
What I'm looking for is if anyone with an auto thats turbo'd and tunes their own ECU's, regarding their shift points (SHIFT PRESSURE). Anyone thats looks into their own roms knows we have the ability to manipulate values in our automatic tranny's.
My tranny is actually in great condition, but since I shift manually with my selector, and plan soon to install a ratchet shifter, I would like to be able to make the adjustments in the rom to make the shifts themselves more responsive.
shifting from 1st to 2nd is already good, but 2nd to 3rd is actually the slowest. I move the selector from 2nd to 3rd and it can be a delay sometimes of 2 seconds before the gear itself actually grabs into 3rd which is kinda lame. and 3rd to 4th or drive, is close to the same.
Any Idea's/help will be awesome. And of course if one of you actually have gone in there and actually made changes that have had positive results and would be willing to help out myself and even others. Please comment here. Thanks

Hmm thats weird mine is very very fast to shift into the next gear but i did notice that at the factory rev limiter it does shift slow I rev mine to 6800 and shifts nicely with the stock values for it .
There is a slight delay to respond maybe half a second but it does not delay the actual shift from gear to gear just my command to it .

Mine shifts tighter too if I'm at a higher RPM. Just not say around 4000rpm or less. Way more delayed at those RPM's . Thats why I'm hoping one of us Auto guys has messed with the values in their ROM to tighten up the pressure values. And if they have what the trim settings were, That way I could have something to work off of. Our Auto's are not nearly as talked about/discussed in forum. It may be something we just have to deal with. But I do think since we do have the ability to change values for our tranny in our roms, there is hopefully someone thats tapped into it that all of us can benefit from. Not just having it be responsive in high RPM's, but all.

I did just flush mine about 3000 miles ago. So I'm good there. I did just think about this though. The EVO 7 had a decent amount of Auto Versions which also happens to be what my Speed Density ROM was based off of, and Maybe someone that owns one of those may chime in. I still say someone here has delved into that portion of their ROM with positive results thats willing to share with the rest of us. A video would be fine.

The one main reason I wanna get it figured out is, when its cold...(tranny). It has a tendency to be real jerky til its warmed up and once its fully warmed up it loses a little to much of its response. Actually an additional tranny cooler may help with it once its warmed up, but still want to fine tune it just like we do our engine mods. I want to get the most out of my cars ability with what I have up to this point.

Just ignore 5th gear thats just a sloppy copy and paste on my part.
As for the shift maps the units are in relation to output shaft speed the default and table are basically unknown for changing shift points but i have some theories.
I can tell from the code that between the 4 map sets (shift maps 1-4) that 1 and 3 are related and 2 and 4 are related.
The transmission logic is called INVECS which has a way of determining via input if the driver is aggressive, if it should brake going downhill, and downshift while uphill etc which is probably why there are 4 sets of maps which it interpolates from.
The maps are definitely setup to switch between 2 variables. In one variable the maps go from 1 and 3 to map set 2 and 4 depending if its set or not. The next one determines within those maps if 1-4 is used or 5-8. One of the variables is likely the brake switch. The other could be an incline/decline switch for downhill shifting.
The left hand side of the maps is throttle position most likely in volts and the right hand side is the output shaft speed in some hz measurement most likely.
Each set of shift point maps is in a set of 2 1-4 being a set and 5-8 being a set which are switched via some method. I'm not positive but for maps sets 2 and 4 the load may be something other than the throttle plate like brake pressure or maybe the incline switch is variable.
Each set of maps should relate to the four gears. Gear 1 being map 1 and 5, Gear 2 being 2 and 6, and so on. These tables may be minimum and maximum shaft speed ranges before the the car downshifts or upshift but that is unknown. It will take testing to find out which map set is currently enabled. I would start with gear 1 and set it to a high value, whatever the max of that table is and see how it responds to gas input, braking. Then we can by assumption find out where the incline/decline values are.

I've already confirmed they work.

Ok...so I will test this out over the weekend. I like your test idea, cause it should give us a little incite as to where to go from there. I do honestly believe if this untapped area, (at least as far as i can find) can be helpful....
