How do you check that? Is that what you have to open the cover and check the jumper settings on?

 

yup

 

Long Term Fuel Trim -

on hot days, intake charge is less dense so the AFR is leaner if kept at the same injector duty cycle as when on a cooler day. on cold days, vice versa. to sort of remedy this, if the ecu sees a pretty lean AFR, the LTFT goes negative and increases injector duty cycle (making the AFR richer) until it sees an acceptable AFR. this is only during closed loop mode/cruising.

during open loop/WOT, the LTFT affects the fuel maps by increasing or decreasing IDC across the board. this means that if the LTFT is negative(ecu seeing lean cruise AFR) it'll increase the injector duty cycle throughout the map. you'll wind up with a richer AFR during WOT.

soooo, pretty much when you base tune, you gotta tune on a median temp weather day or adjust accordingly. if you tune on a cold *** day, then you might have problems on warmer days, etc etc.

 

I was reading an article last night by these guys who tune turbo Toyota pickups. They said tha at low-throttle the STFT and LTFT should be opposite each other. Right now , while driving, my LTFT is at 0.8 and my STFT is at -0.8 today was in the 70's with moderate humidity.

I don't remember my jumper settings, but 3-8-4 sounds right. They're at whatever Ghostrider figured out they needed to be two years ago.

I THINK I may have found yet ANTOHER trick to making the eM work. *******ed GReddy. I'll be running some tests tonight. It may end up that you can't compare the data or save the maps. If it works, I'll do a full writeup of starting the tuning. It'll be easy to make the changes, but you can't save anything or add any toys.

 

All of them that i do are 3/8/3... those are also the same settings i use on my 1g as well.

It is the setting for mitsubishi karmen vortex adjustments.

 

you'll find that miragers and 2g eclipse guys use this setting as well...

 

^^ Be sure to get that write up asap

 

damn, i hate conflicting info. i guess both are up for grabs then.

Great - two gurus who are using different jumper settings. However, eBoy is having a lot of trouble with his and boe, as far as I know, hasn't had the same problems. Perhaps that's the key. I don't know. Why would these two be using diffent settings?

 

worth a friggin try! Why not? Nothing else has worked and frankly, I'll defer to Boe on these matters, especially if he's tuned other Karman vortex MAS's.

Actually, I'm gonna go do it now while I'm still steaming from several worthless runs and I'l let you all know what happens

 

I hope you can come back with great news! If so, and by some miracle this works, I'm buying that WBO2! And it would also be nice to finally figure out what the heck has been your emanage's problem!

 

nope, no effect. And I'm sure you're thinking "well, this thing's not hooked up at all. There's no way it could be this bad." I can sit there and take out fuel at idle until it kills the car. I can retard timing until it sounds like a diesel engine. But I can't get the AF curve to change at WOT.

to be fair I didn't start from complete scratch. I did not update the eM and reset all the parameter settings. It could still be thinking I'm on the other type of Karman but I forgot to check. Long weeknd, long week ahead. I'm going to bed.

 

since you've changed the setting you'll need to go thru the setup process again. Basically hook up laptop, key on/car off, modify the settings and click confirm, shut car off then back to on without starting... close map(will ask you to save... save it)... Then with key still on/car off open emanage support tool again, open the map you just saved, zero it all out, export it... save it again, start the car... go tune and when done export it and save it.

Basically what i do everytime.

By the way... i had an issue with a local guy out here that had emanage on his lancer. He couldn't seem to log on or tune it right. Come to find out he had a pirated cable... wasn't communicating right with emanage. If your using that or trying to use a straight usb with serial connection you need to stop. Invest in the emanage harness and then proceed. It's not a straight connection... i think they cross over on some of the wires in order to make you have to use their connecting harness.

Also there have been reported issues when using a serial to usb adapter... if your laptop doesn't have a serial connector see if you can get an adapter card with serial connection. You really need to connect thru serial port. Emanage is really picky in that way. I have been able to use a keyspan(not sure if that's right name) usb to serial before and it worked great. But others i've tried failed. Just some info.

To date i've installed/tuned basic emanage on 3 lancers. I've yet to install the timing harness though i've tuned them with them. All my settings were 3-8-3 and used the greddy usb to serial connector. No issues... i'm also on the 1.1 software. If you want a copy of that support tool let me know and i'll get you one... maybe your version isn't working right.

 

I'll go through the startup process again. It was already 12:15 by the time I got out to the car, so I didn't have the time to go through the whole process. That'll be tonight's project

I've read that all the extra exporting is what messes up most folks' mapping. I haven't even been saving the maps, but when I import them they look fine. I make the changes and when I close to switch over to the WBO2 program, I tell it "no" at the "do you want to save changes" dialog box.

I'm using a cloned cable but not an additional adapter. I know it's sending signal to the eM, but I won't rule out that it may be part of the problem. GReddy claimed that the cable slowed down the info coming out of the laptop because the eM couldn't process the info fast enough, or something like that.

I'm on support tool v1.11 and firmware 1.39 just downloaded from Mohd a couple weeks ago. I can't think of a more reliable source- unless it's someone who works for GReddy R&D

again, I'll keep everyone posted

 

I've had the worst luck with the pirated cables... in fact i've yet to really get one to work right. That's why i just got the cable direct. Since then i've never had any issues.
