ems for 03 lancer
 

friends got a 03 lancer 0z whatever :3 not evo. he wants to turbo it, what kinda a managment can he use

Re: ems for 03 lancer
 

F/IC is my vote for piggyback, or any true standalone.

Re: ems for 03 lancer
 

This should do it if your willing to research and indulge yourself into the world of fuel injection.

Your welcome.

Re: ems for 03 lancer
 

price went up $90 but the new cable is ------- amazing vs the old cable

still worth the buy

Re: ems for 03 lancer
 

Wow, I ASSumed ECUFlash only supported the Evo.

Re: ems for 03 lancer
 

it supports anything that ecu definitions can located for, and has an obd2 port

Re: ems for 03 lancer
 

stinger :y

Re: ems for 03 lancer
 

I have used it to tune some sti's and a wrx. Those 2007 sti's are a bitch and extremely prone to failure. I did however extract more power out of a stock ecu than he was getting out of his cobb.

Re: ems for 03 lancer
 

evos+sti's+bigger turbo = both fun as hell to drive , in any mental state.
homemade 3" pipe from turbo side port max 65cms

Re: ems for 03 lancer
 

Subaru = worst factory turbo car ever. They burn oil by design, oil pumps ---- if you rev them past 7K, and the stock engines come apart if you push 300. Garbage.

Re: ems for 03 lancer
 

the turbos are the cause of oil burn ;)

stock engines are good for more than 300 if you know which you're talking about ;)

Re: ems for 03 lancer
 

It's a flat-4, Jon. Think about it.

Re: ems for 03 lancer
 

i worked in a subaru garage for a year and have known everyone at that garage since i was a child. the only time oil was added to cars, was when oil changes were done.

I know this thread is pretty much dead, but I figured I'd add on with the EcuFlash comments as I'm pretty much the only mitsu based user of it on here.

EcuFlash does have the definitions for the lancer models in the rom metadata, however to turbo it some physical changes have to be made. First and foremost is the maf...plain and simple the lancer one is not large enough. You would have to upgrade to an Evo 7/8/9 model maf and rescale accordingly. Injectors and the latency voltages also need to be changed as well, depending on the injector size you run. More than likely using the stock 560cc Evo 8 injectors would be your cheapest alternative and you could use the stock scalings from the 94170008/94170015 roms. The injector scaling is roughly 87.9% of the actual flow rating. You will also still have to recirculate the diverter valve between the maf and the turbo. I'd highly suggest going over to the Evolutionm site, they have a specific section just for Lancer's.

Re: ems for 03 lancer
 

The more MAF cars I tune, the more I dislike MAF for any performance application.

Re: ems for 03 lancer
 

Really? I have had limited success on a sti. I just recieved my brand spanking new 2 Ostrich 2.0 and am about to try Nistune on a few things. I have map tracing and datalogging.

Craig was cool enough to upgrade my old 1.0 to a 2.0 and gave me some money off the other one I purchased.

If I come to the conclusion that the if the MAF's suck as you stated I am going to talk to the creator of Nistune to see if there was any way of switching from MAF to MAP.

It's all just an analog signal right?

I have heard that the trick to tuning the MAF's is datalogging and scaling the MAF correctly. I am in no way questoning your knowledgeability. Just looking for input

Re: ems for 03 lancer
 

It's just an analog signal, sure, but the actual code has to be gutted and redone./

Most of my MAF problems are poor MAF placement causing problems, but I still don't like it./

'04 STi has a speed density patch you can run, it's set up like a % VE deal like Megasquirt and fairly straightforward to use.

Re: ems for 03 lancer
 

The Evo crowd has a working speed density patch as well, but some of the tables added and changed to run a map sensor really aren't quite right. Subaru maf's aren't too bad compared to most, DSM mafs seem to be the worst IMO. The biggest issue like Jon mentioned is scaling the maf every time you change intake/filter setups as every one affects the maf differently. My biggest gripe is most turbo maf setups is that they tend to have the IAT sensor built in to them and only read incoming temps before the turbo. Overall though maf setups seem to have an easier time idling with large cams and the part throttle is usually relatively smooth. After a while you start to see maf-based load percentage tables in the same light as a normal speed density table lol.

Re: ems for 03 lancer
 

I've never had a problem idling big cams with speed density. MAFs often don't work right, but maybe that's all the Nissans people bring me.

Re: ems for 03 lancer
 

What are you using for the Nissans you tune? Or is it pretty much what ever they bring you?

Re: ems for 03 lancer
 

Nissan maf's = bigger fail than DSM maf's. What these people don't realize is that the littlest addition in line with the maf will screw up the entire scaling of it and throw everything out of whack with the ecu and tune. That's why intake companies make intakes for maf-based cars with ludicrous stories of ludicrous power gains just from "their intake"...because more than likely "their intake" has so thoroughly screwed up the maf scaling and frequency that it takes the stock tune that's normally very rich to keep it safe and ends up leaning it out and advancing timing in the process. Unless the maf is rescaled to properly match by logging the short term/mid term/long term fuel trims , most "rediculously mad powers gained jdm intakessss" act like nothing more than an AFC. And see my sig to see what Joey and myself think of AFC's. :P Unfortunately every maf has a different algorithm depending on ecu as well, so rescaling can become quite a PITA.

Even GM blow-through mafs have their downsides, and although they tend to read part-throttle cruising and idling very well, they loose their resolution a bit under boost.

Re: ems for 03 lancer
 

They bring me a bunch of NisTune. It works better for some cars than others. Nobody listens to me about where to stick the goddamn MAF, and it's always two inches before the TB with only the diameter of the recirc pipe seperating the two = fail fail fail. All the Nissan guys think a car that sputters and stalls, even if you tap the gas pedal, after boosting is normal as day and night and look confused when you tell them it doesn't have to be that way. :1 If it were mine I'd sell every SR20 swap for a KA24DE with BC cams and run a $350 used AEM with the AEM CAS disc that I bitched at AEM until they gave it to me for free - cheaper than a NisTune daughterboard.

I'm going to start tacking on a $150 "ignorant MAF placement after being told how to do it correctly for $10 extra in materials and no extra time" surcharge.

Don't get me started on the STi owner circus. Half are good dudes who want sweet rides, the other half are nightmares. MAF cars, and the people who like them. :l

I don't mean to thread jack but does anyone know what program I can use to tune a obd1 jetta?
