soooo is anyone still interested in doing a photoshoot tomorrow?

 

I guess this is where Al's opinion differs. Its too bad he just goes ahead and disables these safety's. People had no clue until ECUFlash came along.

i still feel the Evo ECU is a whiny little brat - that complains at the first hint of knock, But i'm just not ready to set all my maps the same.

 

Yeah, all of the color change in the leaves shoudl make it nice.

need some suggestions for locations, though...

 

sweet, what time are u thinking dave? i wanna (NEED TO!) wash the evo prior to any photos being taken. i also might be goin to boston tonight. call me if anyone is interested...

 

i gotta hook up that logging **** (even tho im stock...). that **** is just plain cool to have and be able to do.

 

So after reading all this fresh jive about tunes...does this mean that paying someone is just as effective as having a friend who understands ECU and can do this via laptop? Running a datalogger, and then re-write the maps? I am in need of a tune in the near future. But by the sounds of it, most tuners are figuring this out as a way to make some real easy money by being "cheap" and setting their maps without being very detailed to each vehicle. Am I understanding all this correctly or reading this wrong? I don;t want to pay someone good money if they have a pre-written map that may pertain to the mods that are in my car. The last thing I want is to be there with my car on a dyno, them show me before and afters, and me think that they "custom tuned" my ECU when all they did was put a "fail safe" map in my car. I have no problem working on cars and undrstand them completely, but ECU tuning, maps...etc is all new to me. I am just starting to scratch the surface with all this. ECU newbie

 

Can't you change the knock filtering? I thought there was something in there to do that. I'll have to check.

I know the EVO motor will put up with quite a bit of abuse before giving up the ghost. It's a pretty damn strong motor. Realistically, any motor (well, maybe not a rotary) will tolerate some knock. Modern cars are made to ride the knock sensor to optimize economy and emissions. Still, they are made to the do that at stock power levels. When you start pushing it and asking it to do something it wasn't meant to, you can easily do more damage. This is when avoid knock becomes more important.

 

yeah no one knows exactly how the knock filters work. they are calibrated specifically for the stock noise level. so some people have issues with them once heavily modified. no ones had any good results changing it. I'm assuming its an actual noise filter table - nothing that you can just modify by hand. Its probably just a pre-calculated LUT, based on a high order filter. If someone spends some time with the knock sensing code, they can probably see how its used, and derive the formula and paramters (harmonics) used to generate the LUT. the resounding advice is not to touch them. you can't just edit them by hand.


mikie your the math guru, you should figure it out, or have someone at work tackle the filter table. i bet you could get matlab or maple to solve for the original formula used. then we use that to see what harmonics they used etc.



edit: this is a crazy tangeant, but it probably won't help any. if i could just get it to interpolate octane maps with knock counts around 3 i would be happy. none of this 1 knocksum crap.

 

Al's already put in the time by custom tuning so many car's already - he has a library of tunes he pulls from when putting together a base flash. If you go to someone like DSG however, they don't have a huge library of tunes - they start from the stock maps, and give you a true custom tune.

tuning is far from rocket science though, and i have a real hard time paying someone to do a job i feel i could do better. I really just don't have the time to fully tune my own car. Jestr's base flash only cost me $50 - and it took me less than a couple hours to flash, modify the boost lines and log all the steps in between. If i were to street tune my own car, it would take me more than a week to get it where i want, and then i would have to tweak it for weather changes.

i also prefer street tunes, unlike many other tuners who prefer dynos. I know Dee (with the white IX) says he is strongly against street tuning, and swears by dynos. I have the opposite opinion - i would rather tune by the true load i'm going to see on the street.

The pros on this board say there is nothing wrong with street tuning, but they prefer dynos because its faster to dial in A/F on the dyno and since the dyno can hold RPMs and pinpoint an exact load cell. It would take alot of logging and partial throttle to full throttle tuning to hit some of the load cells. Once the dyno tune is done - you still have to take it on the street to see how close you were to the proper loading on the street. You can't just tune it on a dyno and be done with it.

edit as a side note, Al isn't the only tuner that hacks out the ECU safeties. Jestr also effectively neuters the ECUs over boost safety.

Wow i missed a lot today. Dex to your point I wouldnt let someone drive my car that i didn't trust never the less edit the very thing that keeps its $6000 heart beating.

 

i guess thats the real question, people are spending a good chunk of money on a prized possession, and expect that if they pay someone for a service on their car, to have the same respect for the machine that they do. Thats just so rare, hence why i hate letting anyone touch my car. Even DSG when installing my clutch, they scratched up my door, broke a wiring clip never tightened my negative battery terminal and they didn't "tighten a retaining clip" which popped off, forcing me to have it towed back to them. (they made good on the tow, and fixed everything fast, so i can't complain too much) point is - now that people know the crap Al has been doing to their cars - I can see why people are pissed.

 

^^^ yeah man that is why i would rather learn myself then let anyone touch it. It sucks that time is always a factor.

dont worry dextors we will learn the ways of tuning.

 

Tim is this your way of having unlimited life for your car so you can get a basic flash tune and not worry about the consequences .....by they way thanks for the flashback via Contra When I get my s**t together I will be needing a tune so this info is a big help. Next spring we should do a road tuning session with instructor Dex at the helm

 

I posted that because I really miss nintendo. I still have all my old stuff in a box in the garage. Next rainy day I may try to hook it all up. Blades of Steel anyone

I am still undecided on which way I should go about my tune.
