Courtesey of MrFred, Here you go E6:

 

make sure your cruise trim hasn't changed from the last time... ie +4%???

 

Play with me for a minute would ya......

If I adjust injector scaling to lower cruise LTFT, I would be lowering the scaling thus bringing IDC even higher right?

 

Yea but if that cruise +4 goes closer to 0 because of that, it would even itself out.

Have you changed the LTFT crossover yet or is that at factory settings still? If factory still, the car is adding +4 fuel at WOT above your target.

Cruise LTFT seems to be waffling +2 - +5 depending on which log you look at.


I haven't touched that. What do you mean adding +4?

Are you saying that if my target in the map is 11:1 the LTFT crossover setting causes the ECU to shoot for 7:1?

Bryan, you have a copy of my map I sent to you about 2 weeks ago, you should be able to verify that crossover setting. I cannot as I am at work right now.

 

More around 4%. I've seen -3/-4 LTFT lean out WOT by .5/.6 AFR

It's up to you if you want to stop the LTFT from affecting WOT fueling. I would recommend making it not effect it as it's one less thing to worry about.

- Bryan

 

Shall I do this now while we are trobleshooting? and are you talking about the code Tephra posted here:

Yup that's it. Just know that if you do that and you tuned the car with the LTFT at +4, WOT will lean out after you do that change.

thx tsitalon1, pasted it into evoscan data file hope it works out for me as mine is a 08 edm mr logging using mode23 jdm evox. will keep everyone posted. thx guys

 

Mine is USA version, I'm not sure if it'll work for you. Dbl check by IPW X rpm / 1200

 

In that case it may be better to leave it alone while we are trouble shooting IDC's.

Do you guys concur?

 

Up to you, just know if that LTFT changes, it will change your WOT fueling as well.

- Bryan

 

You are making this more complicated than it is. 9 times out of ten when I see this happen it is the fuel pump on its way out. It is NOT your injectors. At the mods that you have, it is hard to run out of injectors. On the X, it is also possible that it is the relay. So here is what you do NOW:

1. Swap out the fuel pump relay with the high beam relay. Look under the fuse box cap and it will tell you which is which. If your AFR goes rich, then that is your problem. That is something that you can easily fix NOW.

2. If the relay is fine, then change the fuel pump. These things fail even on low mileage cars. It is a Mitsu after all...LOL. A new fuel pump should fix your problem.

 

Lol NJ! Man I think I beat myself in the head saying that lol. But I agree with you 100%.

 

Swapped relays with the HL relay... no change. I guess I'll order a pump, are the walbro still loud like they were in DSM's?

Best price for walbro with plug and play adapter?
