Yes, the AEM will only allow retard. I've spoken with a number of their engineers on this subject but they do not believe it can or will allow advance. I understand from talking to them how they've implemented the system and would tend to agree with their evaluation. There are several ways you could force it into advancing the timing but that's beyond the scope of what i need it to do.

The AEM folk are kind of odd because they swore up and down for weeks that their unit wouldn't work with the lancer but I finally spoke to the actual engineer and described the pulse system and how it conditions the signals and he told me enough to understand how it can be made to work properly. The answer you get depends entirely on who you talk to and how inexperienced they think you are. I'm hoping to have the turbo car the AS group did on the dyno shortly.

One other note that is hopefully helpful for those going turbo. No piggyback will work properly on this setup. You need something to drive the injectors independently. Getting frustrated with the system I did some low level debugging on the ECU itself. The system will severely limit the maximum pulsewidth at lower RPMs no matter what you try. Once it causes an exception the fuel strategy changes and in a way that is very bad for a turbo car.

The limits mean when you spool up it will lean out no matter what you tell the ECU it's flowing for air. The mapping functions are quite complicated inside the ECU and it's got a large number of fuel and ignition tables which I presume are to control the mivec. I haven't spent much time trying to find exactly how it does mivec control but the code itself does not seem to have anything in common with the EVO.

Sum it up here are the options:
Full standalone - will work great if you have a really good tuner but will be very expensive. May be difficult to get factory cluster to work 100% properly and most likely you will need to change a number of engine parts (throttle for example) and a lot of sensors.

Extra Injector - won't really work properly because the factory ECU will try to lean it out in time. As a result you will end up relying heavily on the extra injector and the fuel balance will continue to get worse. As a result, low power numbers and significant chance of a blown up engine. Also going to have fuel trim CEL problems.

FPR - not very accurate and will cost a lot in fuel, plus it tends to be inconsistent depending on the day, temps etc. Since the ECU will try to pull fuel you're looking at getting CEL's because of fuel trim. After a few summers like this you will have spent more on extra fuel than all the other choices combined.

Piggyback that drives the injectors too. Best choice for a basic turbo kit IMO... Provided it allows for O2 spoofing you can keep the factory ECU from staying in closed loop. Costs are reasonable and results reliable if your tuner can get things working properly.

Hope this is helpful to everyone. I am working on funding to provide another alternate solution and will let people know if it pans out.

Hey Dan it's been a little over a month since the map ecu started learning with the new adapter. How's it going??? Is it still in learn mode or did you started to mod the charts a little?? No rushing here just a little anxious. This one's for you

been real busy, but I have been in contact with PMR recently and they want to see what maps the unit has learned so far. I was going to mess with it a little today and tomorrow, my grandmother is coming to town this weekend though so I how much I will get done.

I don't think it's reasonable to expect or hold your breath any time soon for a "crack" for the RA ECU. The code is completely different than the EVO stuff and it will take a considerable amount of work to come up with a crack for it.

read moar. there is a plethora of information if you look around. I promise I'm not giving you a hard time, I'm saving that for when you really start getting on my nerves if you don't believe me, ask around

I think you already ask that on other topic, and you got your answer cause I swear I read it

I wont tell you to search, cause I hate people that tell me the same, Dont see why people cant answer something they know

YES EVO and ANY LANCER cosmetic parts will fit your RALLIART, are you happy now?

so far you've got a long way to go to get on my nerves.

we do jump around a lot. and some of us are on here all the time too

cosmetics are hard to go between evo and other lancers, the evo is wider. other lancers are interchangeable +/- some things IIRC. engine parts are not interchangeable as far as everyday bolt ons are concerned. there are similarities between some of the mitsu engines and drivetrain though, so we have found some parts that cross over.

gotta search though. the car has been out long enough for most things to have been covered. we slowly breaking into the nitty gritty; it takes time to get enough miles on a car to make rebuilding the engine or drivetrain a feasible idea.

READ MOAR, in other words. you will find you answer, and if you don't bump a similar thread so you don't clutter the search pages even more also, mind the rules on here. they enforce them.

enough I'm gonna walk the dog and then hook this mapecu2 up to the laptop again

got some more learned maps from the car this weekend. I have to pull some stuff off a backup disc too though, the laptop crashed around the time I typed that last message and I had to "start over." I still have the files, they just aren't on the laptop anymore. got tons of stuff to do tonight, this is on the list though
