Doesnt the US lancer have a 4g94? I think it does supertuner, lol!
Evo is 4g63T. 1G Eclipse is 4g63. Lancer is 4g94!

 

Ive got a manual and I can do 115mph in 4th which amazed me with the lancer... on a STOCK ecu...

 

Absolutely positive. I've taken it to the 6900 cutout 6 or 7 times now. Twice in my test drive, and a few more times just to freak friends out It purs like a kitten all the way up to it, and even when the rev limiter kicks in, it doesn't sound like anything's wrong (not that I stay there for more than a second, obviously). I believe the 91 octane fuel helps to avoid any timing problems or whatever would cause too much force on the pistons. I trust Rob's engineering, and don't think he would have chosen 6900 (yes, the rev limiter is programmed in there like the rest of the fuel map) if it wasn't safe. He did recommend avoiding redline in 89 octane with the reflash.

Another thing to consider is that when Mitsu puts a rev limiter in, they are doing it to be very safe and keep people (like us) from blowing their engines, so they set it at a very safe level. The new limiter takes it closer to the actual limit. Truth is, most SOHC engines can rev past 7000 rpm, and DOHC can usually go to 8000 and higher.

 

I always believed stroke length was one of the measuring ways on how high the rpm. By hitting 6900, it just boggles the mind.

I have hit fuel cut in my car only once at 6750. I had just glanced at my AFC, and its O2 reading jumped from 1.3 at 6500 to a whopping 1.7 rich at fuel cut. My car shook for about 1.5 sec. It seemed my cam didn't want to turnover at that high rpm, and the ecu took its jolly time trying to shift safely w/o grinding.

I know in manual format drivers can bounce fuel cut whenever. In auto format, it takes a lot of effort and the right situation for the ecu to downshift hard enough and not let off the throttle, just long enough to fool it to go beyond 6500 redline on tach.

 

MY MIRAGE WITH OBX CF SHORT RAM ,AND Exhaust did a 17.3 and its auto.i have seen lancer oz with intake and exhaust doing 16.6.must hab been a bad day or bad driving.i really hope they make the reflash ecu for mirage's .

 

kinda off topic, but is there any way to make shifts faster or change shift points for a reflash for auto ECU's?

 

i got nooborrific question for those who know.

i was just wondering, the a flashed ECU and/or piggyback system like the AEM EMS, wont that **** up ur engine faster?

i mean obviously over time, the engine deteoriates, everything does, but wont this speed that process up?

i mean, something that screws with ur air/fuel ratio, and what not, tricking the engine, wont that have a negative toll on the car?

i really want to get me an EMS or my ECU flashed, but what are the negative points to it?

i didn't bother searching guys, lazy tonight, i just saw this, and i might as well just ask it here if u dont mind.

thx.

 

Bahamut, you can set your rev limiter at anything you want, and then you could take the Lancer's engine right up to 7500 or 8000 if you don't mind throwing a rod right through the hood or something like that. An engine will do almost anything you want it to do until it destroys itself. The trick is deciding how far before it becomes detrimental.

Bobaab, that is actually Rob's biggest challenge with the auto reflash. Shift points are part of an auto's ecu program, but the points change according to how hard you are accelerating, how much of a load is on the car, etc. so I assume the auto reflash will alter the shift points for more performance, or maybe to be more sensative to the way you drive (like city versus racing)

Deuzforever13, that's actually a good question. The reflash and piggy back are not very extreme, and won't wear your engine any more than driving like a maniac without the mod will do. But yes, if you drive a car hard, it will suffer in the long run. Other than that, I run 91 octane fuel when I take the new ecu to its limits, which helps a more precise timing and burn rate. If you need to know more on this, ask Boeturbolancer, who was instrumental in the development of the reflash.
