Ok guys me and my friend took on the challenge of tuning the car and by no means did we have any idea what we were doing our goal was to have a safe tune that was a little better than what we had before.. we took it to the track tonight to see what it could do and i was very upset with my times! When you take a look at our log please keep in mind that this is our first time tuning with dsmlink and we know that there are some clear issues and it needs some fine tuning.. one major thing that i know forsure is wrong is my timing is way low and the maf tables are messed up... at WOT my A/F ratio is always within 12.5 to 11.8 which isnt bad also i was pretty happy with our knock ratio during WOT

So i would really really appreciate if you guys could steer us in the right direction and get us on the road to make some decent power! I went 13.9 at 96 mph with a 1.8 60ft

I know i definately need a 2g maf at the least, and a fmic but with the stuff i have i know its possible of 12 second passes no problem im just a little bummed at what i ran but i know theres alot more to be done and move in a positive direction :thumb:

I'm new, but your tune looks really screwed up to me. airflowperrev is too low at idle, disable mafclamp cause you are running a 1g maf, log more stuff. stft, ltft, combinedft, wideband, tps. maybe go to ecmtuning and watch the demos, it really helps.

Oh yeah, and you have a CEL for a injector circuit malfunction, and it looks like your front o2 is on it's way out.
 
I don't have my wideband ran to the ecu yet I do need to do that, and yes I know the tune is way off like I said this is our first time ever doing it.. I'll do another pull tomorrow and log some more stuff
 
Watch the demo videos and setup a base tune. I can't even figure out how you managed to adjust the fuel/timing/maf sliders. Did you guess? What injectors are you running? Do you have a afpr?

it's not so much the fuel or timing as it is the maf sliders...

OP, you do realize there are three sub-forums for this type of thread...?

I guess I'll point you in the right direction:

http://www.dsmtuners.com/forums/ecm...efore-you-ask-ecmlink-dsmlink-log-advice.html

And you really should not be tuning (or trying to, rather) without logging your wideband...

oh and ditch that 1g maf asap! :)
 
Ok thanks for the replys so far guys it looks like there's Lot of useful stuff you guys posted, I'm gonna show him all this tomorrow and it should help us out a lot and o running denso 550 injectors as well
