Yep, keydivers chipps are just as he said, basically un-reprogrammable chips that do alot of the features of DSMlink. Great for those who wanna quickly create a cheap setup, but dont wanna spend the 565 that DSMLink runs. Keydivers chips are something like 70 dollars, so they are very cheap. Dave, my friend has three of them. I actually was a beta tester for keydivers 2g chips way back in the day.

This is 16g-95gsx, sorry, Im on my friends computer.

 

sweet. i just hooked up my dsmlink. but he didnt send me the usb connector like i asked, so now i need to find a laptop w/ a serial port

damn.... yea my car knocks like a bitch when I tried changing some of the settings... blah, cant really tune my car I guess until I get injectors pump and fmic and a few other things. like a better turbo...the car runs better w/ dsmlink than it does w/ the regular ecu tho.

my runs are on dsmlink in the engine part of the forums, just search for my username "elementalwindx" to find the post..

 

I think that 16g-95gsx and KPW are saying the exact same things they are just being said wrong.

Everyone with knowledge of psi knows its just a value of pressure, and is meaningless unless the setup is taken into consideration.

With that being said a certain setup can only flow so much lbs/ per min before knock begins to play a role. Wether you are looking at what lbs/per min or psi value, you are still stopping at that value to further tune out knock. I think all Chris was trying to say was, glancing at the psi value was a easier more convenient way of tuning. Once the baseline 40lbs per min or so was understood, then you can focus more on squeezing more psi through tuning; while using the lbs per min feature as another tool to show that the airflow is also increasing as well.

Airflow does infact have a direct correlation with horsepower, I think its something like 10.5 hp x (airflow per min) equates to what your motor "should" be making at the flywheel.

 

Any tips on the clutch-cut? (NLTS) feature? I just finished wiring that up. Interesting how it drops my idle whenever I hit the clutch now.

 

You have to enable to clutch-cut feature while you are connected to the ecu through dsmlink. The idle drop is because its not enabled yet, and I notice it everytime I reset my ecu and have to turn the NLTS back on.

 

i skimmed some of hte BS and it seems to me to be one of those arguements where two people are arguing two totally different things, that don't have any relation.

first off, the idea of the boost estimation and it's usefulness, is due ot hte fact that not everyone has a 3 bar MAP sensor. it can't really be argued it's not a usefull parameter, as boost is just as relevant as timing, A/F, etc. it is not a solid state, it changes, so the ability to have it logged can be usefull, even if it is just an estimation.. people have tuned off of EGT for years, and that is only an estimation, just in a different way.. a number is a number.. the trick is knowing how to use it

second, boost is irrelavent? go turn your shit up to 45 lbs of manifold pressure, and then try telling me "it doesn't matter, only my lbs/min matters!". your point about the compressor maps was accurate, BUT you had it backwards. looking at lbs/min and NOT looking at manifold pressure, to judge load, is just looking for disaster unless you know the compressor map well enough.

boost is a variable of compression, it isn't, and should never be used as an estimate to airflow. manifold pressure and airflow are two totally different values, to be considered as two totally different factors. ignoring boost is jsut as dangerous as ignoring timing or A/F

boost, A/F, timing.. choose the two you want and tune accordingly.. or put in some good gas and have the best of all 3

last, if i totally was off on my assumption of what the arguement was over, my apologies, i only skimmed it, since it looked like a bunch of boring

also, estimation of hp based on airflow is not accurate.. you can flow all the air you want.. it's how much boom you make from it that matters

 

I agree, when in neutral it says my car has like 300hp sometimes, and while driving, i average just at 100hp lol. even while doin a run. kinda funny how useless that lil calculation seems.

 

I'm sorry Dave, you're wrong. When compared to airflow in lbs/min, looking at boost is unimportant. Your example is horrible....no one would run 45 psi without expecting either a lot of airflow, or disaster.

I said potential for power. Some of us have logged airflow, made calculations, and then taken it to the dyno to see how accurate we were. And we were very accurate.

wow. so throw away that boost guage and only look at lbs/min

and don't ask me why you blow head gaskets when you do!

you fail to understand that they measure two totally different things

 

Please Dave...you are not speaking to the dragva mass. If you want to call me an idiot, do it with less words.

I'm not going to throw my boost gauge away because it is a useful tool in determing at a glance whether the car is boosting normal.

The arguement I put forth was that logging an estimated boost or a 3bar map sensor was irrelevent when you could log airflow instead. Why? Because airflow gives you a better picture of what is going on when compared with simply knowing the pressure at the intake manifold.
