Im always willing to help Thunder just hit me up. Did you ever switch to the evo rom? I recommend that to everyone as its night and day as far as tuning goes.

 

+1 hey 03lance when you do a full pull all the way up to redline and when you shift do you get a knock light at all?


I can do a full 3rd gear pull now but I can't seem to get a good a shift in without the CEL flashing, any clues on what might be the case? I can send you my rom and tell me what you think and what I should do so I can adjust it

 

Sadly I too am still stricken with the fast shift knock I can't figure it out. I always thought it was due to my throwout bearing but sounds like a few of you experience the same issue. In my vid if u pay close attention u can tell wjen I shift into 4th and I hesitate for a second before mashing the gas again to ensure I don't get that knock. I think this is going to be my next issue I confront because my fuel is looking awesome and my timing is almost there but plenty good to leave and venture onto this issue.

 

Yea I switched over and it's running like crap right now I have a lot of work to do. Even my start ups are really rough.

 

EDIT** im going to start a new thread in the timing area that we can all participate in so if we have problems with tuning our tephra mod we can go in there and ask questions and post answers. The tephra mod in the tuning is pretty much how to download it and tweak to get your car running

 

Sounds Valid....a timing/knock thread for converting is probably necessary....but the info needs to be there, don't want to just start advising people without a good baseline. As far as the evo ROM, like 03lances said, yeah it's night and day as far as tuning...I can already tell that with only 1 pull. But, without the ability to even cruise at 2500 rpm without getting 20+ knocks, something else is wrong and that needs to be addressed, probably for everyone who makes the switch.

I was really concerned when 03lances first said "yeah, I'm adjusting my knock sensitivity" because I thought, ok...boom goes the engine. Really though, I think it's the right direction, although posibly wrong approach. You know there's that Knock Filter map in the stock lancer rom, but no such thing in the evo rom, I wonder what else "knock wise" is missing from the lancer or evo roms that is different between the 2. I'm thinking there are frequencies that get picked up by the sensor, and they are calibrated on a "per engine" basis.....so if we use the wrong ones, we'll pick up knock where it isn't, and miss knock where it is! /me is pretty freakin scared at this point....

 

This is the drawback to having our type of setup, either way someone goes they have some kind of specific issues that go along with it. Knock settings being the definite burden. It took me awhile to get up the courage to start adjusting those knock settings but rest assure I dont do ANYTHING without probable cause and without educating myself on the subject. I feel like I have been able to sucessfully eliminate alot of false knock I presonally have using the tools I have available to me. I have always had the impression that you just expressed above hornstar although with no way to adjust some thing like that you have to use the tools you do have to do the best you can. Just in the last couple weeks I have really helped everything on and off boost without touching my timing and just dialing in my fuel more precisely. I have especially noticed leaning out that one section from 2500-3500 really helped me with my off boost throttle response in that lower area. Ok time to start researching this shift knock...

 

Found this thread with a quick search. I am going to log this and see what happens and adjust if I need to but thought I would share

That does make a crap ton of sense...the "flow" of the shift sort of thing, follow where it goes, the same way you smooth out a timing map for just accelerating through it. I'm not there yet, but I wish you luck with it!

 

Ok did some logging but I am not seeing a pattern yet. I think I am still being too suttle though, I am shifting quick but looking at my logs is showing my only going about half throttle for the first half second. However there were a couple times in there I did go about 85% right after the shift and do see some knock there. Even with the half throttle I see samples that go from 35 degrees down to 7 or even 4 degrees in about a 1/4 second with no knock being logged. This is however preliminary logs I am going to do more but wanted to give the old girl a break cause I was running her hard lol. Definately fun though she is running VERY good I am so proud my baby is growing up haha

 

Well I had to go up to the big city again today to return something. Brought a buddy with me and he is pretty impressed with the power increase. I have noticed since leaning out the fuel that pull does not drop as much as it did before with more weight in the car. Seems like before running a little more rich it would feel quite a bit slower when I would take someone for a ride to check it out. Not the case anymore I am happy to report. I am starting to feel really satisfied with my power and think I am going to schedule a dyno run here soon and post my numbers. I hope there actually close to my VDR numbers that would be awesome.

 

u know i used to rele notice the power loss when i had a passenger....have u solved this lol

 

Sure seems like it. After leaning out the fuel it really seems like I am not losing nearly as much pull as I was before

 

What are you running for AFR's?

 

I know the closer you get to 12.5 the more power you ought to make.....but the more dangerous you'll be. As far as how to know what exactly is safe vs what isn't, no idea...I'm thinking EGT is a good indicator. But, I'm curious what target AFR you are going for by full boost around 4000 RPM...and what's your EGT showing at that point vs idle and cruise?

Excellent news about the "happiness" with the tune, I know the entire forum is proud for you, you've got one hell of a car there.
