Ok so here is what I have to tune with. I have dsmlink v2 a maft and a autometer a/f gauge. Can I tune with that? If so where do I start. Money is tight right now and I want my car to run good. When I hit about 5 pounds of boost my car bucks like it doesnt want to go no where. And also when I let off the throttle and hit it again it back fires. Any ideas? Im trying to learn I could use some help. Thanks

Absolutely you can tune with the WBO2 and DSMLink. Make sure you have your WBO2 analog output wired into the ECU so you can log. Then take a look at the DSMLink Wiki which will guide you through the beginning steps of starting your tune.
 
It looks like he said he just has an autometer af gauge.

If that IS the case, then I would seriously look into getting a wideband. No matter what you try to tune with you're going to NEED a wideband, and if you're trying to tune a turbo car for high boost w/o a wideband I'd liken that to trying to find a needle in a hay stack.

You're probably bucking from a boost leak or running far too rich or lean...
 
Yes thats what you need a wideband, what kind you looking for? Im going for the innovative because it is going to work well with link when i do get it.

ANY tuning system worth it's salt should be able to use native wideband to do closed loop (being that narrow band sensors are pretty crappy). Innovate is what I use, and it's what i would consider to be the best. AEM wideband's have issues w/ their analogue output being a different signal than what the gauge displays.
 
I wouldn't tune anything turbo w/o using a wideband... really you're shooting yourself in the foot if you do because there is NO way to know exactly what your AFR is.

If you want to tune your car for lots of power, you will need a wideband... otherwise you're just trying to make a baseball land somewhere in the ball park....
 
It wasn't that long ago that we really didn't have affordable widebands. You can get a decent tune by logging the timing curve, knock, egt's, tps, rpm's, and narrowband O2's.
Will you know your exact AFR? No.
Will you be able to find the ragged edge and eek out the last pony? No.
Can you make your car run well at an efficient boost level and remain safe? Yes.


PS
Should you make fun of how old I am? No.

Innovatives are worse about that than AEM.

I was starting to think I was the only one still around from that era! :thumb:

I remember when the cheapest wideband was $1000 and everyone had an EGT gauge. Seems like only yesterday. And I want to believe I'm not old.

Well... my LC-1 is just a sensor and controller... two analogue outputs... there is absolutely NO difference in the two outputs... where as the AEM UEGO units have the gauge/controller as one unit... and the gauge/controller displays a different afr than the analogue output does. Their white papers are wrong, and the uego's are not programmable to change what afr they display for a certain voltage.
